Farmers in Ethiopia participated in research evaluating different seeding rates for teff production using a seed spreader. Over two years, farmers preferred lower seeding rates of 5-20 kg/ha mixed with sand compared to the recommended 30 kg/ha or typical 35 kg/ha rate. An economic analysis also found the lower 15 kg/ha rate mixed with sand to have the highest benefit-cost ratio. Both the farmer preferences and economic analysis support using the lower 15 kg/ha seeding rate mixed with sand as the most feasible option for farmers in the study area.
The document summarizes a study that evaluated the effects of different rates of nitrogen (N) and phosphorus (P) fertilizers on the quality of snap bean pods grown in Jimma, Ethiopia. Five levels of N (0-164 kg/ha) and four levels of P (0-138 kg/ha) were applied in a field experiment. The results showed that increasing N and P rates significantly improved several quality parameters, including pod length, diameter, and marketable yield. Specifically, applying 82 kg N/ha and 46 kg P2O5/ha optimized pod quality by increasing length, diameter, fiberless nature, and marketable yield compared to other treatment combinations and the unfertilized control.

Genotype by environment interaction and stability of extra-early maize hybrid...IJEAB
Maize (Zea mays L.) is the most important cereal crop produced in Ghana. However the change in environmental conditions, the expansion of maize to new agro-ecologies coupled with inadequate maize varieties available for the different environments affects yield improvement programmes in Ghana. Hence, the study is to investigate the influence of genotype by environment interaction on the maize hybrids and to identify stable and high yielding hybrids with superior agronomic for famers use in the country. The objectives of the study was to investigate the influence of genotype by environment interaction on the maize hybrids and to identify stable and high yielding hybrids with superior agronomic performance for famers use in Ghana. Thus, fifteen extra-early maize hybrids and three locally released checks were evaluated in a randomized complete block design with three replications in two locations in Ghana. The experiment was carried out at KNUST and Akomadan which represent the forest and forest transition zones of Ghana. Nine of the hybrids out of the fifteen hybrids evaluated produce above the average yield and the effect of genotype, location and genotype by location interaction was significant for grain yield. The GGE biplot used in this study revealed that TZEEI-1 x TZEEI-21, TZEEI-6 x TZEEI-21, TZEEI-15 x TZEEI-1 and TZEEI-29 x TZEEI-21 were high yielding and stable hybrids because they were closer to the ideal. The GGE biplot also identified Akomadan as the most ideal testing environment for these hybrids under irrigation.

Effect of regulated deficit irrigation on growth and yield of sorghumAlexander Decker
This document summarizes a study on the effects of regulated deficit irrigation on the growth and yield of sorghum. The study consisted of different irrigation regimes (100%, 75%, 50%, 25% of full irrigation) applied to two soil types and measured various growth parameters. The results showed that irrigation regimes of 100% and 75% performed better in terms of growth, water use efficiency, and economic returns compared to 50% and 25% deficit irrigation. Additionally, there were some interaction effects observed between deficit irrigation and soil type. Overall, the study recommends the use of 75% regulated deficit irrigation for optimizing sorghum growth in this agricultural zone.
Maize Phenology and Crop Stand in Response to Mulching and Furrow Irrigation ...Premier Publishers
The field experiment was conducted to investigate the effects of mulching materials and furrow irrigation methods on phenology and crop stand of maize at Werer, Middle Awash Valley of Ethiopia during 2017/18 cool cropping season. Split plot design with three replications, in which the irrigation methods (Conventional, Fixed and Alternate Furrow) were assigned to main plot and the three mulching materials (plastic, straw and no mulch), were to the sub-plot. Result showed that maize phenology and crop stand was affected by different furrow irrigation methods and mulching materials. But interaction of irrigation methods and mulch had no significant effect on maize phenology and crop stand except days to phenological maturity. Conventional furrow irrigation took less days to emergence (8.4 days) and tasseling (66.67 days). Plastic mulch took less day to emergence (6.9 days), tasseling (62.67 days) and silking (69 days) respectively. Physiological maturity (114.3 days) arrived earlier in fixed furrow with plastic mulch. The conventional furrow irrigation (29600ha-1) and white plastic mulch (29956ha-1) resulted in the maximum maize stand. In conclusion, conventional furrow irrigation and plastic mulching had improved phenological stages and maize crop stand at Werer and other similar agro ecology.
Interactive Effects of Stream Sizes and Furrow Geometry on Furrow Irrigation ...AZOJETE UNIMAID

Breeding for dual purpose attributes in sorghum. Identification of materials ...Maarouf Mohammed
This study investigated the potential for developing high-yielding dual-purpose (grain and fodder) sorghum cultivars. 122 sorghum genotypes were screened and 21 were selected based on traits like early flowering, high regrowth, plant height, panicle size, and grain/fodder yield. These 21 genotypes plus 3 checks were evaluated in field trials. Significant variation was found among genotypes for fodder and grain yields. Some genotypes like SG33 and S.25Abu70 showed potential for high dual yields. Positive associations were found between grain and fodder yields and related traits, suggesting dual-purpose cultivars can be developed by combining high levels of these traits.
Poultry manure application and fallow improves peanut production in a sandy s...Agriculture Journal IJOEAR
To meet our food security demands, Papua New Guinea (PNG) needs to improve smallholder subsistence agriculture by promoting the production of cash crops that mature early and have a high market value. Peanut is a typical example of a cash crop which potentially has a high market value, but pod yields are low due to declinein soil quality. A field experiment was conducted under 4 different land use systems (LUS) to evaluate the effects of continuous peanut cultivation on peanut pod yield and on selected soil properties. Peanut pod yield declined significantly under the continuous peanut and peanut/corn rotation systems; while the poultry manure and land fallow systems significantly increased pod yield. Over the 3 cropping seasons, significant changes in organic carbon; extractable potassium and CEC in all cropping systems occurred, while changes in total N was significant in the peanut/corn rotation and poultry manure cropping systems only. No significant changes in bulk density; field capacity; electrical conductivity; soil pH and available phosphorus were observed in all the 4 LUS over the 3 cropping seasons. We suggest that adequate fallow periods of more than 1 year and poultry manures are applied to enhance soil quality and improve peanut productivity and/or sustain peanut production in marginal lands under continuous cultivation
Breeding for Dual purpose in sorghum. Effect of harvest options and genotypes...Maarouf Mohammed
This document evaluates the performance of dual-purpose sorghum genotypes under different harvest options in Sudan. A study was conducted across seasons to test genotypes for fodder and grain yield when harvested at different stages. The results showed that genotype performance varied significantly depending on the harvest option and season. When harvesting the main crop for forage and the ratoon crop for grain, the cultivar Abjaro performed best in winter, while S.25Abu70 performed best in summer. When harvesting both grain and stover from the main crop, either Abjaro or S.25Abu70 could be recommended depending on farmer preferences for yield or earliness. Overall, the study found that different genotypes and harvest options are needed
Determination of the optimal level of the fertilizing elements N, P, K on the...Innspub Net
The objective of the test is to determine the best formula of the NPK elements for two local varieties improved of corn. The studied plant material is composed of local populations improved P1, P2. The factorial test is driven with two P1 varieties, P2 and four doses of NPK according to an experimental device in blocks of Fischer to four blocks. The doses of 20 – 10 – 10, 30 – 15 – 15, 10 – 5 – 5 and 40 – 20 – 20 correspond respectively to the T1 treatments, T2, T3 and T4. On the T2 (2,073 m ± 0,009) P1 is observed of the heights raised of stem. The T4 (1, 85 m ± 0,173) recorded a stem raise of P2. The T2 (30, 75 ± 1,500) P1 reached the highest number of grains in a row. The T1 (30, 75 ± 1,258) P2 got high number of grains in a row. Greater number of grains in an ear is observed on T3 (520 ± 15,491) of P1. The greatest number of grains per ear is noted on the T2 (510,5 ± 10,630) of P2. The T2 (4, 20 t ha-1 ± 0,12) P1 recorded better outputs in grains. The T1 (4,035 t ha-1 ± 1,831) P2 got the best output in grains. The corresponding T2 to the dose (30 – 15 – 15) could be kept for the P1. The corresponding T1 to the dose (20 – 10 – 10) could be recommended for the P2 to increase the productivity of corn in the zone of survey.
Genetic and Morphological Diversity Analysis of Ethiopian Mustard (Brasica ca...Premier Publishers
This document summarizes a study that analyzed the genetic and morphological diversity of 49 Ethiopian mustard landraces collected from different regions. The landraces were evaluated for traits like days to flowering, days to maturity, seed yield, and oil content. Significant variation was found among genotypes for most traits, indicating genetic diversity. The highest heritability was found for thousand seed weight. This diversity provides opportunities for selection and breeding to improve traits like yield.
The document discusses opportunities for plant breeding to adapt crops to climate change. It notes that breeding takes 5-25 years but new technologies can accelerate it. Various challenges are mentioned, such as which future environments and diseases to breed for, how much genetic variation exists, and which traits and methods should be used. Trait dissection, genetic mapping, and accelerated breeding strategies using markers are presented as opportunities to develop new crop varieties suited to future climates through exploiting genotype-environment-management interactions.
Correlations and Path Analysis of Some Quantitative and Qualitative Character...ijtsrd
Durum wheat is the second most important triticum species next to bread wheat. Ethiopia is one of the centers of diversity for durum wheat. The present study was to determine the interrelationship and direct and indirect effects of yield component traits on grain yield of Ethiopian landraces durum wheat for further breeding activities of yield improvement. Out, 97 durum wheat accessions along with 3 improved varieties were evaluated in 10 x 10 simple lattice design during 2018 main cropping season at Mata Sub site of Haro Sabu Agricultural Research Center. Analysis of variance revealed highly significant differences among accessions for all traits. More than 36 of accessions were superior in mean grain yield than the standard checks. Grain yield exhibited positive and significant correlation both at genotypic and phenotypic level with most of the characters such as plant height rp = 0.22, rg = 0.25 , harvest index rp=0.79, rg = 0.78 , biological yield rp = 0.31, rg = 0.30 , number of kernels per spike rp = 0.17, rg = 0.21 , spike length, rp = 0.36, rg = 0.39 , and hectoliter weight kg hl 1 rp = 0.44, rg = 0.45 . The association between yield, and yield related characters through phenotypic genotypic path coefficients revealed that biological yield, spike length, harvest index and plant height exerted highest positive direct effect on grain yield. This suggests that simultaneous improvement in these characters might be possible Zewdu Tegenu | Dagnachew Lule | Gudeta Nepir "Correlations and Path Analysis of Some Quantitative and Qualitative Characters in Durum Wheat (Triticum Turgidum L.)

Effects of Tillage methods on some soil physical properties, growth and yield...AZOJETE UNIMAID
Disc ploughing plus disc harrowing (DP+DH) was found to be the most effective and profitable tillage method for improving soil physical properties, growth, and yield of watermelon in sandy loam soil. DP+DH treatment resulted in the highest watermelon yield of 31.0 t/ha, as well as the largest fruit weight, length, and diameter. For zero tillage (ZT), the highest yield was 26.5 t/ha. Overall, DP+DH enhanced watermelon growth and yield the most, while ZT was found to be unsuitable.
Agronomic approaches for managing drought stress include:
1. Choosing drought tolerant crop varieties that escape drought conditions through early flowering.
2. Adjusting planting dates to avoid drought periods. Delaying sowing dates can reduce yield.
3. Optimizing sowing depths from 4-8 cm depending on the crop to maximize yields.
4. Seed priming treatments like water soaking or salt solutions can improve seed germination and establishment.
An Agronomic field study was conducted at University of Limpopo Experimental farm, Syferkuil, over two summer growing seasons to determine the optimum phosphorus (P) rate and also assess the productivity of pigeonpea under intercrop with maize. Five P rates (0, 15, 30, 45, and 60 kg P ha-1) were evaluated under sole and intercropped pigeonpea. Treatments were laid out in a randomized complete block design with four replicates. Results revealed that variable P fertilizer rates exerted significant effect on pigeonpea grain yield in both seasons. Highest grain yields of 922 and 1141.7 kg ha-1 under sole and intercrop plots, respectively, were achieved at 45 kg P ha-1 during first and second seasons, respectively. However, the predicted optimum grain yield of 734 and 1034 kg ha-1 based on the response model was achieved at 52.67 kg P ha-1 and 42.84 kg P ha-1, in the respective seasons. Intercropping achieved a significantly higher pigeonpea grain yield (+37%) during second year than sole cropping following P addition; with over 21% mean grain yield advantage across the two planting seasons. Hence, depending on the inherent soil-P level, application of 42-53 kg P ha-1 under pigeonpea/maize intercrop represents the range at which P is optimum for maximum pigeonpea grain yield and better returns for farmers.
Weed control is an important agronomic practice that improves growth and maximizes yield in maize. An experiment was carried out to investigate the ‘effect of different weed control methods on the growth and yield of maize (Zea mays L.) in the western highlands of Cameroon. The work was carried out during the 2017/2018 main cropping season from the 14th of March to the 14th of July at the Institute of Agricultural Research for Development (IRAD) Bambui experimental field. The experiment was laid out in a Randomized Complete Block Design (RCBD) and replicated three times. The experiment comprised of seven treatments: weedy check or control (T1), constant hand hoeing (T2), delay hand hoeing (T3), pre-emergence herbicide application of Atrazine 90 DF ( 0.9 kg ha-1) (T4), post-emergence herbicide application of Ultramais 100 SC (1.9 litre ha-1) (T5), pre- herbicide application of Atrazine 90 DF ( 0.9 kg ha-1) + Ultramais 100 SC (1.9 litre ha-1) (T6) and delay post-emergence herbicide application of Ultramais 100 SC (1.9 litre ha-1) (T7). The white maize variety CHC 201 (“KASAI”) was used during the experiment and sown in plot sizes of 4 m x 5 m with a planting density of 80cm by 50cm with 2 plants per station with the aim of achieving a plant population of 50,000 plants ha-1. All agronomic practices were followed from planting to harvesting. The data recorded were plant height, number of green leaves per plant, leaf area, stem girth, days to 50% tasseling, days to 50% silking, ear height, ear length, ear girth, number of gain rows per ear, number of gains per ear, 1000 grain weight and grain yield.. The data collected were analyzed with the aid of STATGRAPHICS Plus 5.0 Software and ANOVA was run to find the differences between the various treatments. The highest 1000 grain weight (314.13g) came from the pre-emergence plus post-emergence herbicide application treatment and did not differ significantly (P˃0.05) from the constant hand hoeing treatment (307.83g). The lowest 1000 grain weight (234.67g) was seen in the weedy check treatment. The constant hand hoeing had the highest grain yield (6.27 ton ha-1) and this did not differ significantly (P˃0.05) from the pre-emergence plus post-emergence herbicide application treatment (6.07 ton ha-1). The lowest grain yield (3.18 ton ha-1) was seen in the weedy check treatment. From the study, the pre-emergence plus post-emergence herbicide application may be recommended for increasing maize yield particularly in the case of high scale production.

Effect of nitrogen fertilizer rates and intra-row spacing on yield and yield ...Premier Publishers
A field experiment was conducted at Gode Polytechnic College demonstration farm in 2013 under irrigation to observe the effect of six N rates (0, 46, 69, 92, 115 and 138 kg ha-1) and four intra-row spacing levels (7.5, 10 12.5 and 15 cm) on yield and yield components of onion (Allium cepa L.). The experiment was laid out according to randomized complete block design in factorial arrangement with three replications. Results of the analysis revealed that the interaction effects of N rates and intra-row spacing showed highly significant (P<0.01) effect on harvest index, fresh biomass yield, dry biomass yield, total bulb yield and marketable bulb yield. Thus, according to the result of partial Budget analysis application of 138kg N ha-1 planted at 7.5cm plant to plant distance was found the best treatment than others in relation to yield and yield components of onion under Gode condition.
This document summarizes a study on improving the productivity and nutrition of baby corn through evaluating the effects of intra-row spacing and nitrogen fertilizer rates. The study found that narrower intra-row spacing of 15cm and a higher nitrogen rate of 200kg/ha led to taller plants, thicker stems, higher leaf area index, ear weight and length, and highest baby corn and stover yields. This treatment combination is proposed for baby corn production in the study area and similar agro-ecologies. Further evaluation of additional varieties and nitrogen rates above 200kg/ha is recommended for future work.

We suggest that adequate fallow periods of more than 1 year and poultry manures are applied to enhance soil quality and improve peanut productivity and/or sustain peanut production in marginal lands under continuous cultivation
Breeding for Dual purpose in sorghum. Effect of harvest options and genotypes...Maarouf Mohammed
This document evaluates the performance of dual-purpose sorghum genotypes under different harvest options in Sudan. A study was conducted across seasons to test genotypes for fodder and grain yield when harvested at different stages. The results showed that genotype performance varied significantly depending on the harvest option and season. When harvesting the main crop for forage and the ratoon crop for grain, the cultivar Abjaro performed best in winter, while S.25Abu70 performed best in summer. When harvesting both grain and stover from the main crop, either Abjaro or S.25Abu70 could be recommended depending on farmer preferences for yield or earliness. Overall, the study found that different genotypes and harvest options are needed
Determination of the optimal level of the fertilizing elements N, P, K on the...Innspub Net
The objective of the test is to determine the best formula of the NPK elements for two local varieties improved of corn. The studied plant material is composed of local populations improved P1, P2. The factorial test is driven with two P1 varieties, P2 and four doses of NPK according to an experimental device in blocks of Fischer to four blocks. The doses of 20 – 10 – 10, 30 – 15 – 15, 10 – 5 – 5 and 40 – 20 – 20 correspond respectively to the T1 treatments, T2, T3 and T4. On the T2 (2,073 m ± 0,009) P1 is observed of the heights raised of stem. The T4 (1, 85 m ± 0,173) recorded a stem raise of P2. The T2 (30, 75 ± 1,500) P1 reached the highest number of grains in a row. The T1 (30, 75 ± 1,258) P2 got high number of grains in a row. Greater number of grains in an ear is observed on T3 (520 ± 15,491) of P1. The greatest number of grains per ear is noted on the T2 (510,5 ± 10,630) of P2. The T2 (4, 20 t ha-1 ± 0,12) P1 recorded better outputs in grains. The T1 (4,035 t ha-1 ± 1,831) P2 got the best output in grains. The corresponding T2 to the dose (30 – 15 – 15) could be kept for the P1. The corresponding T1 to the dose (20 – 10 – 10) could be recommended for the P2 to increase the productivity of corn in the zone of survey.
Genetic and Morphological Diversity Analysis of Ethiopian Mustard (Brasica ca...Premier Publishers
This document summarizes a study that analyzed the genetic and morphological diversity of 49 Ethiopian mustard landraces collected from different regions. The landraces were evaluated for traits like days to flowering, days to maturity, seed yield, and oil content. Significant variation was found among genotypes for most traits, indicating genetic diversity. The highest heritability was found for thousand seed weight. This diversity provides opportunities for selection and breeding to improve traits like yield.
The document discusses opportunities for plant breeding to adapt crops to climate change. It notes that breeding takes 5-25 years but new technologies can accelerate it. Various challenges are mentioned, such as which future environments and diseases to breed for, how much genetic variation exists, and which traits and methods should be used. Trait dissection, genetic mapping, and accelerated breeding strategies using markers are presented as opportunities to develop new crop varieties suited to future climates through exploiting genotype-environment-management interactions.
Correlations and Path Analysis of Some Quantitative and Qualitative Character...ijtsrd
Durum wheat is the second most important triticum species next to bread wheat. Ethiopia is one of the centers of diversity for durum wheat. The present study was to determine the interrelationship and direct and indirect effects of yield component traits on grain yield of Ethiopian landraces durum wheat for further breeding activities of yield improvement. Out, 97 durum wheat accessions along with 3 improved varieties were evaluated in 10 x 10 simple lattice design during 2018 main cropping season at Mata Sub site of Haro Sabu Agricultural Research Center. Analysis of variance revealed highly significant differences among accessions for all traits. More than 36 of accessions were superior in mean grain yield than the standard checks. Grain yield exhibited positive and significant correlation both at genotypic and phenotypic level with most of the characters such as plant height rp = 0.22, rg = 0.25 , harvest index rp=0.79, rg = 0.78 , biological yield rp = 0.31, rg = 0.30 , number of kernels per spike rp = 0.17, rg = 0.21 , spike length, rp = 0.36, rg = 0.39 , and hectoliter weight kg hl 1 rp = 0.44, rg = 0.45 . The association between yield, and yield related characters through phenotypic genotypic path coefficients revealed that biological yield, spike length, harvest index and plant height exerted highest positive direct effect on grain yield. This suggests that simultaneous improvement in these characters might be possible Zewdu Tegenu | Dagnachew Lule | Gudeta Nepir "Correlations and Path Analysis of Some Quantitative and Qualitative Characters in Durum Wheat (Triticum Turgidum L.)

Effects of Tillage methods on some soil physical properties, growth and yield...AZOJETE UNIMAID
Disc ploughing plus disc harrowing (DP+DH) was found to be the most effective and profitable tillage method for improving soil physical properties, growth, and yield of watermelon in sandy loam soil. DP+DH treatment resulted in the highest watermelon yield of 31.0 t/ha, as well as the largest fruit weight, length, and diameter. For zero tillage (ZT), the highest yield was 26.5 t/ha. Overall, DP+DH enhanced watermelon growth and yield the most, while ZT was found to be unsuitable.
Agronomic approaches for managing drought stress include:
1. Choosing drought tolerant crop varieties that escape drought conditions through early flowering.
2. Adjusting planting dates to avoid drought periods. Delaying sowing dates can reduce yield.
3. Optimizing sowing depths from 4-8 cm depending on the crop to maximize yields.
4. Seed priming treatments like water soaking or salt solutions can improve seed germination and establishment.
An Agronomic field study was conducted at University of Limpopo Experimental farm, Syferkuil, over two summer growing seasons to determine the optimum phosphorus (P) rate and also assess the productivity of pigeonpea under intercrop with maize. Five P rates (0, 15, 30, 45, and 60 kg P ha-1) were evaluated under sole and intercropped pigeonpea. Treatments were laid out in a randomized complete block design with four replicates. Results revealed that variable P fertilizer rates exerted significant effect on pigeonpea grain yield in both seasons. Highest grain yields of 922 and 1141.7 kg ha-1 under sole and intercrop plots, respectively, were achieved at 45 kg P ha-1 during first and second seasons, respectively. However, the predicted optimum grain yield of 734 and 1034 kg ha-1 based on the response model was achieved at 52.67 kg P ha-1 and 42.84 kg P ha-1, in the respective seasons. Intercropping achieved a significantly higher pigeonpea grain yield (+37%) during second year than sole cropping following P addition; with over 21% mean grain yield advantage across the two planting seasons. Hence, depending on the inherent soil-P level, application of 42-53 kg P ha-1 under pigeonpea/maize intercrop represents the range at which P is optimum for maximum pigeonpea grain yield and better returns for farmers.
Weed control is an important agronomic practice that improves growth and maximizes yield in maize. An experiment was carried out to investigate the ‘effect of different weed control methods on the growth and yield of maize (Zea mays L.) in the western highlands of Cameroon. The work was carried out during the 2017/2018 main cropping season from the 14th of March to the 14th of July at the Institute of Agricultural Research for Development (IRAD) Bambui experimental field. The experiment was laid out in a Randomized Complete Block Design (RCBD) and replicated three times. The experiment comprised of seven treatments: weedy check or control (T1), constant hand hoeing (T2), delay hand hoeing (T3), pre-emergence herbicide application of Atrazine 90 DF ( 0.9 kg ha-1) (T4), post-emergence herbicide application of Ultramais 100 SC (1.9 litre ha-1) (T5), pre- herbicide application of Atrazine 90 DF ( 0.9 kg ha-1) + Ultramais 100 SC (1.9 litre ha-1) (T6) and delay post-emergence herbicide application of Ultramais 100 SC (1.9 litre ha-1) (T7). The white maize variety CHC 201 (“KASAI”) was used during the experiment and sown in plot sizes of 4 m x 5 m with a planting density of 80cm by 50cm with 2 plants per station with the aim of achieving a plant population of 50,000 plants ha-1. All agronomic practices were followed from planting to harvesting. The data recorded were plant height, number of green leaves per plant, leaf area, stem girth, days to 50% tasseling, days to 50% silking, ear height, ear length, ear girth, number of gain rows per ear, number of gains per ear, 1000 grain weight and grain yield.. The data collected were analyzed with the aid of STATGRAPHICS Plus 5.0 Software and ANOVA was run to find the differences between the various treatments. The highest 1000 grain weight (314.13g) came from the pre-emergence plus post-emergence herbicide application treatment and did not differ significantly (P˃0.05) from the constant hand hoeing treatment (307.83g). The lowest 1000 grain weight (234.67g) was seen in the weedy check treatment. The constant hand hoeing had the highest grain yield (6.27 ton ha-1) and this did not differ significantly (P˃0.05) from the pre-emergence plus post-emergence herbicide application treatment (6.07 ton ha-1). The lowest grain yield (3.18 ton ha-1) was seen in the weedy check treatment. From the study, the pre-emergence plus post-emergence herbicide application may be recommended for increasing maize yield particularly in the case of high scale production.

Effect of nitrogen fertilizer rates and intra-row spacing on yield and yield ...Premier Publishers
A field experiment was conducted at Gode Polytechnic College demonstration farm in 2013 under irrigation to observe the effect of six N rates (0, 46, 69, 92, 115 and 138 kg ha-1) and four intra-row spacing levels (7.5, 10 12.5 and 15 cm) on yield and yield components of onion (Allium cepa L.). The experiment was laid out according to randomized complete block design in factorial arrangement with three replications. Results of the analysis revealed that the interaction effects of N rates and intra-row spacing showed highly significant (P<0.01) effect on harvest index, fresh biomass yield, dry biomass yield, total bulb yield and marketable bulb yield. Thus, according to the result of partial Budget analysis application of 138kg N ha-1 planted at 7.5cm plant to plant distance was found the best treatment than others in relation to yield and yield components of onion under Gode condition.
This document summarizes a study on improving the productivity and nutrition of baby corn through evaluating the effects of intra-row spacing and nitrogen fertilizer rates. The study found that narrower intra-row spacing of 15cm and a higher nitrogen rate of 200kg/ha led to taller plants, thicker stems, higher leaf area index, ear weight and length, and highest baby corn and stover yields. This treatment combination is proposed for baby corn production in the study area and similar agro-ecologies. Further evaluation of additional varieties and nitrogen rates above 200kg/ha is recommended for future work.

This study evaluated 6 varieties of bread wheat on 27 farmers' fields in 3 districts of southern Ethiopia. Variety and location significantly affected plant height, spike length, seeds per spike, and yield. The highest-yielding variety was Digalu, which farmers in all districts ranked first due to its adaptation, disease resistance, quality, and market value. Variety Tay was also well-adapted and ranked second in 2 districts. However, variety HAR-604 performed poorly and was susceptible to diseases. The study concluded that Digalu can be recommended for all areas, while Tay is suitable for some locations.
Growth and Yield Response of Bread Wheat Variety Grown Under Varying Seed Rat...Premier Publishers
Wheat is among the most important staple crop globally. However, constrained by appropriate agronomic practices. Therefore, the information on the interaction effect of seed rate and weeding period is useful to identify the effective time of weeding for high yield of wheat. Thus, the present study conducted at Amuru district of Horro Guduru Zone, Ethiopia in 2019 cropping season with the aim of identifying optimum seed rate and appropriate time of weeding to improve production and productivity of bread in the area. The experiment was laid down in randomized complete block (RCB) design with three replications. The treatment was arranged in factorial combinations of four weeding intervals (farmer practice, weeding at two weeks after emergence, three weeks after emergence and four weeks after emergence) and three levels of seed rate (125 kg, 150 kg and 175 kg-1).The result showed that days to 50% heading, days to maturity and effective tillers per plant were highly significantly (p<0.01) affected by the interaction effect of weeding time and seed rate. Moreover, interaction effect of weeding time and seed rate was significantly (p<0.01) affected the weed above ground dry biomass. Guizotia scabra (22.47%) with population density (370), Phalaris paradoxa (22.10%) with population (364), Plantago lanceolata (18.58%) with population density (306), and Bidens piloso L. (8.74%) were the dominant weed species competing with wheat in the study area. Minimum relative weed density (26.6%) weed dry biomass (1.7gm) and maximum weed control efficiency (98.08%) was recorded at weeding four weeks after emergence and 175kgha-1seed rate. Thus, the finding suggest grain yield was increased (52.3%) when weeding four weeks after emergence over farmers practice and 13.75% at 175kg seed rate.

Field experiment was conducted in Humera in 2015 main cropping season in a factorial randomized complete block design (RCBD) to study the performance of sesame under different supplementary irrigation applications and nitrogen fertilizer rates. The study consists of four levels of nitrogen fertilizer rates (0kg N2/ha, 23kgN2/ha, 37.5kgN2/ha and 46kgN2/ha) and three levels of supplementary irrigation; rain-fed (I0), four irrigations (I4), and six irrigations (I6). Nitrogen fertilizer was applied in two splits, with the first half at sowing and the remaining half 30 days after emergence. Data on plant height, number of capsules per plant, number of seeds per capsule, thousand seed weight, harvest index, aboveground biomass and grain yield were recorded. The analysis of variance (ANOVA), in indicated that application of nitrogen fertilizer significantly (p<0.05) affected sesame grain yield. The highest grain yield 423.4kg/ ha, and 455kg/ha was obtained from application of 46kg nitrogen per hectare, and six supplementary irrigation. The results obtained in this experiment showed that, application of supplementary irrigation could be an important climate change adaptation strategy in areas where onset and cessation of rainfall occur.

The knowledge of gene action and heterosis also helps in identification of superior F1 hybrids in order to use further in future breeding programs. The objective of this study was to estimate the amount of standard heterosis of the pipeline maize hybrids for grain yield and yield related traits. A total of eleven pipeline maize hybrids and two standard checks (BH546 and BH547) were evaluated using randomized complete block design with three replications during the 2015 main cropping season at Northwestern Ethiopia. Mean squares due to genotypes were highly significant (P ≤ 0.01) for most grain yield and yield related traits indicating the existence of genetic variation among the evaluated genotypes. The standard heterosis ranged from -38.72 to 33.65%and the highest heterosis was recorded for CML395/CML202//CML464 cross. The observed highest heterosis for grain yield and related traits indicated the possibility of increasing yield by exploiting heterotic potential of maize genotypes. The information generated by this study could be useful for researchers who need to develop high yielding maize hybrids.

This study evaluated the effect of mineral and organic fertilization on some agronomic parameters of cassava nursery plants Bocou 1 and Yavo (Manihot esculenta Crantz). For this purpose, 1200 cassava plants were produced on 10 substrates based on soil supplemented with chicken droppings, sawdust, carbonized rice husks and NPK 10 18 18. The trial was conducted in a completely randomized Fisher block design on two 880 m2 subplots 6 m apart. The planting density was 1 m x 1 m with three replications per treatment, i.e. 600 plants per cassava variety. The manures used were chicken manure, charred rice husks and NPK 10-18. Results showed that treatments T2S6 (T2: Carbonized rice husks; S6: Substrate 6) and T2S3 (T2: Carbonized rice husks; S3: Substrate 3) induced better plant growth than the other treatments for the two cassava varieties studied. The highest yields were obtained with treatments T3S2 (T3: NPK 10 18 18; S2: Substrate 2) (456.83 t/ha) and T2S8 (T2: Carbonized rice husks; S8: Substrate 8) (423.25 t/ha) at Bocou 1 and Yavo, respectively. The results of this study will help optimize cassava production in Côte d’Ivoire and improve the purchasing power and livings standard of producers.

A field experiment was conducted to assess the effect of rates and time of nitrogen fertilizer application on yield and yield components of sorghum in northern Ethiopia. The treatments consisted of four rates of nitrogen (23, 46, 69 and 92 kg N ha-1) and three time of N application (1/2 dose at sowing and 1/2 dose at mid-vegetative, 1/2 dose at mid-vegetative and 1/2 dose at booting stage, 1/3 dose at sowing, 1/3 dose at mid vegetative and 1/3 dose at booting stage). The main effect of rate of N application showed significantly the highest days to flowering, days to physiological maturity, plant height, panicle length and biomass yield (10716 kg ha-1) at 92 kg N ha-1. Similarly, the highest days to flowering, leaf area index (2.86) and panicle weight were obtained from three split application and the maximum biomass yield (10142 kg ha-1) was recorded from two split application of N (1/2 dose each at mid-vegetative and at booting stage). The interaction of rates and time of application of nitrogen had significantly the highest 1000 kernels weight (44.67 g), grain yield (4635 kg ha-1) and harvest index from 69 kg N ha-1 in three split application. Economic analysis showed that maximum net benefit of 33053.23 ETB ha-1 from 69kg N ha-1 in three split application. Based on the results, it can be concluded that application of 69 kg N ha-1 in three splits to be appropriate to increase the productivity of sorghum in the study area.
Assessment of genotype by environment interactions and grainAlexander Decker
The document discusses a study that evaluated 100 extra-early maize hybrids across three environments in Ghana to determine the presence and effects of genotype by environment interactions (GxE) on grain yield. The study found significant effects of genotype and environment on grain yield, but GxE was not significant. Using GGE biplot methodology, five hybrids - TZEEI 8 x TZEEI 51, TZEEI 5 x TZEEI 53, TZEEI 21 x TZEEI 39, TZEEI 27 x TZEEI 36, and TZEEI 4 x TZEEI 6 - were identified as high yielding and stable across environments.

Reaction of Elite Faba Bean Genotypes for Soil Acidity StressAI Publications
Soil acidity is one of the major abiotic stresses in Ethiopian highland agriculture that limits crop production in general and a prime factor of faba bean production in particular. The goal of this study was to investigate the effect of soil acidity stress on grain yield of 50 faba bean genotypes of which 22 were released varieties. The experiment was comprised two stress levels (lime treated and untreated) arranged in randomized complete block design with three replications. The analysis of variance for both potential yield (YP) and stress yield (YS) indicated significant differences among fifty genotypes. Also, significant differences were observed among faba bean genotypes regarding seven soil acidity stress indices. Based on the YP, the genotypes Moti, CS20DK, EKLS/CSR02010-4-3, Cool-0024 and EH07023-3, had the highest yield under non-stressed condition, while the genotypes CS20DK, Obse, Wolki, Didi’a and Dosha displayed the highest yield under stressed condition. In terms of grain yield (g/5plants) CS20DK was ranked 2nd and 1st with 113.24g and 79.56g under non-stressed and stressed, respectively. However, based on the overall performances of multiple stress indices (YI, STI, MP, GMP, HM, SSI and RYR) Wolki, Dosha and Obse were confirmed as soil acidity stress tolerant genotypes whereas Wayu was identified as the most sensitive genotype. The STI, MP, GMP and HM indices exhibited strong correlation with YP, while YI showed strong correlation with YS indicating YS can discriminate soil acidity tolerant genotypes with high grain yield under stress conditions. Hence, use of multiple stress indices confirms the performance consistency of the genotypes considered for the stress.

The experiment used five levels of N (0-92 kg/ha) and four levels of P (0-30 kg/ha) in a randomized complete block design. Results showed that increasing the N level significantly increased various yield components. The P level also significantly affected plant height, leaf length, leaf area, and number of tillers and plants per plot. The interaction between N and P significantly impacted leaf area and number of plots per plot. The highest yields were obtained at 92kg/ha N and 30
This document discusses a study on the effects of planting date and planting method on wheat yield in Nigeria. The study tested four planting dates (1st November, 15th November, 1st December, 15th December) and three planting methods (drilling, dibbling, broadcasting) in two locations. Results showed that later planting dates of 15th November and 1st December produced higher grain yield compared to earlier dates. Drilling and dibbling methods also resulted in higher yields than broadcasting. Based on these results, the study concludes that planting wheat from 15th November to 1st December using drilling or dibbling is best suited for the study areas.

A universal model for managing the marketing executives in nigerian banksAlexander Decker
This document discusses a study that aimed to synthesize motivation theories into a universal model for managing marketing executives in Nigerian banks. The study was guided by Maslow and McGregor's theories. A sample of 303 marketing executives was used. The results showed that managers will be most effective at motivating marketing executives if they consider individual needs and create challenging but attainable goals. The emerged model suggests managers should provide job satisfaction by tailoring assignments to abilities and monitoring performance with feedback. This addresses confusion faced by Nigerian bank managers in determining effective motivation strategies.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Abstract
Farmers’ participatory evaluation of seeding rates on teff using seed spreaders in Wolaita Zone, South Ethiopia
was conducted during the main rainy seasons of 2010 and 2011. Six treatments viz. 5, 10, 15, 20, 30
(recommended rate) and 35 kgha-1 (farmers practice) were used in the experiment. Treatments lower than
recommended and farmers seeding rate were mixed with seed spreader (i.e. dry sand). The experiment was laid
out in Randomized Complete Block Design with four replications. Teff variety (DZ-Cr-37) was used. Before
commencing the experiment, awareness creation and on job trainings were given to Farmers Research Group
(FRG) farmers. The farmers’ evaluation result during 2010 and 2011 in the field, based on visual observation
(i.e. lodging intensity, expected grain and straw yield ) indicated that they preferred lower seeding rates such as
5kg/ha, 10kg/ha, 15kg/ha and 20kg/ha mixed with sand as 1st, 2nd, 3rd and 4th rank, respectively. In addition, the
average economic analysis value during 2010-2011 using benefit: cost ratio, depicted an increasing trend up to
15kg/ha and then a decreasing trend in subsequent to 15kg/ha. Furthermore, the grain yield, farmers preference
and economic analysis justified that the lower seeding rates particularly 15 kgha-1 mixed with sand could be
economically and technically feasible for farmers since it save seeds (100 % over 30 kgha-1), efficient utilization
of improved seed; and to address seed demand of resource poor farmers. Hence, lower seed rates (10 and 15 kg
ha-1 mixed with sand) are technically and economically feasible for farmers in the study area.
Key words: FRG, Seeding rate, Seed spreaders, Teff
1. Introduction
Teff (Eragrostis tef (Zucc.) Trotter) is the most important and traditional staple cereal crop in Ethiopia and is
grown extensively under various climatic and soil conditions. It is a dominant cereal accounting about 32% of
the total cereal production (MoARD, 2007) and provides over two-thirds of the human nutrition in Ethiopia
(Lacey and Llewellyn, 2005; Stallknecht et al., 1993). Teff is major grain crop next to maize in Wolaita Zone,
Southern Region of Ethiopia which occupies 23% of the land covered by grain crops (SNNPRS, 2007).
Mean while, seed is considered as a basic input for agricultural development due to the fact that it ensures grain
production and adds new genetic resource to the total crop gene pool (Raj et al., 2007).The deficiency of good
quality seeds available to farmers is one of the biggest issues in agricultural development in Ethiopia and it is
believed this makes farmers difficult to obtain enough harvest from their farming. Hence wise utilization of seed
through appropriate seeding rate is crucial.
In Ethiopia, the recommended seed rate for teff is 25 to 30 kg/ha (ESE, 2001), but farmers often use 40–50
kg/ha, because it is difficult to distribute the seed evenly, the viability of farmers’ own seed is reduced (i.e.
uncertainty of the germination percentage), and to suppress weeds at early stages (Tefera & Belay, 2006). Since
few years, in countries abroad Ethiopia such as USA, South Africa and Australia, teff has been cultivated for
grain and fodder purposes. They accomplish sowing using planters at optimum rate of 5 to 8 kg seed/ha
(Stallknecht et al., 1993), which implies that an Ethiopian farmers (i.e. at 30kg/ha) are being utilizing extremely
higher seed rate by 275% to 500% as compared (30Kg ha-1) with (8kg/ha) and (5kg/ha), respectively. The figure
is becoming higher when compared with farmers using the above recommended rate.
The small seed size of teff is taken as agronomic limitation during teff production that poses a problem during
sowing and after germination (Seyfu, 1997). At sowing, the very small seed size makes it difficult to control
population density and its distribution. After germination, the uneven plant stand has an impact on growth,
nutrient use efficiency of the crop and crop yield (Seyfu, 1997). Furthermore, the dense population in teff
could have an effect on seed quality since it favors competition, lodging, disease and insect prevalence. Seed
spreaders (seed mixers) are materials (sand, dry soil, sieved compost, etc) which are used to further improve the
performance of tiny seeds during planting. Reports indicated the paramount importance of seed spreaders on
small seeds (Rathore, 2001; Naturland 2002, Owuor et al., 2001). Accordingly, seed spreaders make seed bulk
and aids to broadcast tiny seeds uniformly by hand, saves poor farmers from extra seed cost, contribute in seed
saving and help to realize better growth yield. Furthermore, it is easily applicable for teff and other tiny seeded

crop and might also easily adoptable by farmers. Therefore research was initiated with the dual objectives.
First one was to introduce a farmer participatory research method called “Farmer Research Group based
Research” (hereinafter called as FRG approach) to find out the reason of shortage of seeds together with FRG
farmers on their location. Second one was to share the outcomes of farmers’ preference with the economic
analysis. Furthermore, information on the issue on teff growing areas of Ethiopia, including the study area is
very scanty.
2. Research Methodology
2.1. Description of the Study Area
This experiment was conducted in Wolaita Zone, Duguna Fango Woreda (Edo Kebele), South Ethiopia in the main
rainy season of 2010-11. The research site is found in the altitude 1591 m.a.s.l, latitude 07002’14.9” N and
038000’44.5”E with the minimum and maximum average annual temperature is 160C and 260C, respectively; and
the average annual rainfall of 950 mm. The site was selected for the experiment because teff is highly cultivated in
the area and also due to the presence of established Farmers Research Group (FRG).
2.2. Treatments and Experimental Design
Six treatments viz, 5, 10, 15, 20, 30 (recommended rate), and 35 kgha-1 (average farmers practice) were used in the
experiment. Among the treatments 5, 10, 15 and 20 kgha-1 were mixed with dry sand. Dry sand that passed 2mm
diameter sieve was used for the experiment. Since farmers hand have accustomed with higher seeding rate (i.e. 35
kg/ha), its volume was 1st determined. Lower seeding rate treatments such as 5, 10, 15 and 20 kgha-1 were
placed in labelled container with 35kg/ha. Then, the difference in space from the labelled volume by 35kg/ha and
applied rates (i.e. 5, 10, 15 and 20 kgha-1) were filled with dry sand; and both were mixed before sowing. Finally,
keeping the difference in the seed amount, each treatment was kept at constant volume in which farmers’ hand has
been familiar for broadcasting. The experiment was conducted in Randomized Complete Block Design (RCBD)
with four replications. Treatments in the 1st replication were arranged in an easy to grasp way for the farmers i.e.
according to the increasing order of the seeding rate amount. The remaining replications were assigned using
randomization technique. Size of each plot was 9m2 (3m x 3m). The spacing between plots and blocks were
0.75m, respectively; and one meter free area was left around the experimental field.
2.3. Farmers Participation during Experiment
This approach emphasizes composition of multidisciplinary research team, researchers from the university,
development agents (extension officers) and group of farmers organized for research and extension (FRG), who
conduct research based on farmers’ needs. The FRG members were 10 during 2010; and 16 during 2011. For FRG
members, an awareness creation was given on the necessity of participatory evaluation, site selection, field and lay
out preparation, sowing, fertilizer application, field management and participatory crop performance evaluation. In
addition on job training on how seed is mixed with sand, purpose of mixing and crop management practices were
given to participant farmers. This was done to ensure their full participation and to let them feel responsible on
each and every step from the beginning to the end, except scientifically technical matters. Furthermore, when
researchers did technical things, farmers were briefed the purpose of the activity (e.g. agronomic data
measurements, soil sample collections, etc).
2.4. Crop Management
For the experiment early maturing teff variety (DZ-Cr-37) was selected since it is preferred by many farmers. Prior
to sowing, the experimental land was well prepared; and sowing was done through hand broadcasting. Fertilizer in
the form of urea at a rate of 50kg/ha and DAP at 125kg/ha were applied. DAP was applied at sowing time while
urea was applied by split application (half at planting and the remaining half at mid tillering stage). Important
agronomic practices were uniformly applied to all experimental plots as often as required. Disease and insect
prevalence was checked regularly and there was no incidence of disease and insect pest in the experimental field.
2.5. Data Collected and Analysis
2.5.1. Farmers stand evaluation preferences
The data were collected before harvest (i.e. at crop physiological maturity stage). Farmers were grouped into four
and each group was assigned to one replication. Farmers’ used their own criteria viz. lodging intensity, expected
grain and straw yield. Each group had a secretary and after a number of round way trips on assigned replication
coupled with a hot discussion, they came up with common ranking preferences. Finally each group presented its
preference to other participants. The preference of each group, total summary and average preference rank of FRG

farmers is indicated on table 1 and 2. To summarize all rankings, tally method was used in which the first, second,
third, fourth, fifth and sixth ranking had weighted value of six, five, four, three, two and one points, respectively.
2.5.2. Partial economic analysis
The following methods were used for partial economical analysis
a. Total income (birr) = income from grain yield + straw
b. Total variable costs (birr) was taken from input costs (seed and fertilizers) keeping labor, land constant
c. Marginal cost (birr) was calculated by deducting the total variable cost of each seeding rate with respect to
the cost of previous seeding rate
d. Net benefit (birr) = Gross Return - Total Variable Cost
e. Marginal net benefit (birr) was calculated by deducting the net benefit of each seeding rate with respect to
the net benefit of previous seeding rate
f. Benefit: cost ratio = Net benefit of each seeding rate
Total variable cost of its seeding rate
3. Results and Discussions
3.1. Farmers Evaluation during Experiment
Farmers evaluation result revealed that farmers grouped for the evaluation during 2010 and 2011 were came up
with different preferences. However, most of the participating farmers preferred lower seeding rates when mixed
with sand than higher seeding rates (Table 1a and 1b). The farmers’ evaluation in 2010 indicated that 5kg/ha,
10kg/ha, 15kg/ha and 20kg/ha mixed with sand were preferred as 1st, 2nd, 3rd and 4th rank, respectively (Table
1a). Similar trend of preference ranking were noticed during 2011 (Table 1b). Lodging intensity, expected grain
and straw yield were the most frequently indicated justifications for selecting treatments in the field. This suggests
that FRG approach has some positive effects on extension process due to farmers’ better understanding of
scientific data. Furthermore participation of farmers is helpful in order to bring more precise information during
research output applicability to wider context. Similarly, variable selection and use of farmers’ own criteria during
participatory variety evaluation was reported by Nishikawa, 2011. In addition, the importance of farmers’
participatory research at all stages was reported by (Abule Ebro et al., 2011 and Nishikawa, 2011).
3.2. Economic Analysis
The average grain yield of teff did not statistically influenced by seeding rate during 2010 and 2011(data was not
presented). However, partial economic analysis (Table 2a and b) was carried out to evaluate the economic
performance of different seeding rates. Economic analysis indicated that seeding rates showed differences the
gross returns, net returns and benefit: cost ratio (Table 2a and b). During 2010, the highest gross returns (10,008
birr /ha), net returns (8313birr/ha) and benefit: cost ratio (5.25) was recorded from treatment receiving 30kg/ha,
30kg/ha and 10kg/ha mixed with sand, respectively (Table 2a). Total variable cost in treatment receiving 35kg/ha
was higher (1766.5 birr/ha) followed by 30kg/ha (1694.5 birr/ha) compared to other treatment combinations. Least
cost of cultivation (1334.5 birr /ha) was recorded from 5kg/ha plus sand with benefit: cost ratio of 4.52 (Table 2a).
During 2011, the highest gross returns (11,160 birr /ha), net returns (9609.5 birr/ha) and benefit: cost ratio (6.35)
was recorded from treatment receiving 20kg/ha sand, 20kg/ha and 15 kg/ha mixed with sand, respectively (Table
2b). Highest total variable cost was recorded in treatment receiving 35kg/ha (1766.5 birr/ha) followed by 30kg/ha
(1694.5 birr/ha) compared to other treatment combinations. Least cost of cultivation (1334.5 birr /ha) was recorded
from 5kg/ha plus sand with benefit: cost ratio of 6.05 (Table 2b). Furthermore, the average benefit: cost ratio for
2010 and 2011 showed an increasing trend up to 15kg/ha and then a decreasing trend in subsequent to 15kg/ha
(Fig. 1). Partial economic analysis result during 2010 and 2011 in general revealed that 15 kg/ha mixed with sand
were economically feasible for teff production in the study site.
4. Summary and Conclusion
It is true that few years ago, an increasing trend for the grain cost of teff was observed and particularly the average
unit seed price was high for the improved seed. In the mean while, farmers in the study area are not readily
accessible to the improved seed due to scarcity. Hence, it is worthwhile to use lower seeding rates by mixing with
sand than higher seeding rates. This is evidenced by the fact that raising the seed rate did not bring corresponding
significant increment in grain yield of teff. Farmers’ evaluation and the economic analysis indicated the better
performance of lower seeding rates mixed with sand. Among seeding rates, 15kg/ha mixed with sand seems
technically and economically feasible in the study site since it save seeds by 100% over 30kgha-1, adequate area
coverage with relative uniform distribution, promotes efficient utilization of improved and quality seed; prevent

farmers from extra seed cost and also highly suitable for addressing resource poor farmers. Moreover, the absence
of weed which is a common problem in other teff growing areas during lower seeding rates is not a concern for
FRG members in the study area. This is because of the common practice of multiple and continuous cropping on
the small land holding size. In general, FRG approach has some positive effects on extension process due to
farmers’ better understanding of scientific data and should be considered as important tool for the applicability of
research outputs to wider context.
