The tomato is the one of the most famous crops in Pakistan. It is used and consumed as fresh as well as in processed form. Its botanical name is Solanum lycopersicon Mill. The proposed study had been conducted in the year 2017-2018 in order to find the best combination of water soluble NPK fertilizers as compared to control. Five different types of water soluble fertilizers were collected from different sources and were applied at 5% concentration during the entire growing period of the tomato crop. The experiment was designed using Randomized Complete Block Design (RCBD) with five treatments and three replications of each. Different vegetative, reproductive and bio-chemical parameters were recorded and analyzed statistically at 5% level of significance. The treatments were compared using LSD test. It was concluded that different NPK water soluble fertilizers showed variation in physical and bio chemical parameters in tomato plants as compared to control. The plants showed variation in plant height, No. of fruit per plant, fruit yield per hectare, Individual fruit weight, fruit weight per plant, No. of diseased fruit per plant, date of first harvest, Fruit color Fruit length (cm), fruit size (cm), fruit firmness, total NPK contents, vitamincmg Chlorophyll concentration, pH, (TSS), Electricity conductivity (EC) and Titratable acidity Among all the water soluble treatments, the T3 treatment (WSF 20:20:20) yielded the comparatively better results as compared to other WSF treatments. So it was concluded that T3 was the recommended water soluble fertilizer for tomato.

A study of sorghum tolerance to low P condition was conducted in two experiments : (1) in nutrient solution and
(2) in acid soil. The aim of this study was to obtain information on the genetic variability and heritability of agronomic characters that could be used as selection criteria in low P condition and to obtain information on gene action that controlled agronomic characters of sorghum.The plant materials used in this experiment were F2 segregating population derived from the cross between B69 and Numbu. The first experiment was conducted in the green house of Bogor Agricultural University. B69, Numbu and F2 population were grown hidroponically for 14 days. Composition of the nutrient solution used in the experiment followed the method suggested by Ohki with modification of P concentration. P is given in the form of KH2PO4: 0.001 mM. The results showed that shoot dry weight (SDW) and total dry weight (TDW) had high estimate of heritability and moderate genotypic
coefficient of variance (GCV), thus these characters can be used for criteria selection for low P tolerance at seedling stage. The significant value of skweness from the distribution shoot dry weight in F2 segregants, indicate the presence of complementary epistasis gene action, whereas normal distribution of total dry weight showed additive gene action. The second experiment was conducted in acid soils of Bogor District Experimental Field Tenjo, Bogor. The results showed that stem diameter, panicle weight and grain yield per plant had high heritability and wide GCV value, indicating these characters can be used as the selection criteria in selecting
sorghum genotypes for low P tolerance in acid soil. Based on the skewness values, all of the agronomy characters
observed in this study were influenced by additive gene action. Get more articles at: http://www.innspub.net/volume-7-number-3-september-2015-ijaar/

Evaluation of Different Growing Substrates on Lettuce (Lactuca sativa) under ...Innspub Net
Hydroponic technology has many benefits that it is highly productive and conserves water and land most especially if natural resources are scarce. Normally, plants grow inside a greenhouse that controls temperature, light, water and nutrition. The study was conducted to evaluate the performance of different growing substrates on lettuce under a non-circulating hydroponics system. It was conducted at Cagayan State University – Piat Campus from September to October 2019. The Completely Randomized Design (CRD) with four replications was used to test the following treatments: T1 – Rockwool, T2– Coco peat, T3 – Carbonized Rice Hull (CRH) and T4 – Sawdust. Results show that plants under coco coir (T2)–obtained the tallest and longest roots while the most number of leaves and heaviest fresh biomass was registered in rock wool (T1). In terms of water pH, the result revealed no significant differences among treatment means. In the absence of rock wool, the coco coir can be used as an alternative as growing substrates for a non-circulating hydroponics system since they did not differ significantly.

Glyphosate-resistant (GR) soybean was one of the first major applications of genetic engineering in field crops and offered farmers a vital tool in fighting weeds. Weeds are a problem for soybean production in Cuba, so our work aim was the GTS 40-3-2 event introgression into Cuban varieties. Two local cultivars were crossed with transgenic genotypes that carry the event. From F1 to F3 generations, individual plants that produced more than 60 g of seeds per plant were chosen to obtain next generation. Individual lines were selected from F4 generation. F5 and F6 generations of five selected transgenic lines and their relatives were chosen to evaluate seven
agronomic traits throughout the summers of 2012 and 2013. A Random Block experimental design was done. First flowering (R1) and maturity (R8) stages of all genotypes were affected by planting date. Plant height of I1B2- 3, I1B4, I36B4 and RP5 lines ranged from 80 to 111 cm. I1B2-2 and I1B2-3 lines would be suitable for mechanized harvesting because they had the insertion of the first pod at 14.63 cm and 13.93 cm respectively. I36B4 line produced the greatest number of pods per plant (127). Transgenic lines produced more than 180 seeds per plant and 100-seed weight ranged from 13.75 g to 17.46 g. Seed yield per plant of transgenic lines and their parents IncaSoy36, CEB2 and CEB4 weren’t statistically different. These results could be a start point for other studies
involving larger areas, different planting dates and localities. Get more articles at: http://www.innspub.net/volume-7-number-4-october-2015-ijaar/

The main objective of this study is determine the responses of Bambara groundnut [Vigna subterranea (L). Verdc.] to application methods of plant growth promoting rhizobacteria inoculant and time of sowing after inoculation in Agbani area of Enugu, South East Nigeria. Field trials were conducted at the Teaching and Research Farm of the Faculty of Agriculture and Natural Resources management, Enugu State University of Science and Technology in 2015 and 2016 planting season. The experiment was a 2 × 3 factorial trial in a randomized complete block design with three replications. The treatments consisted of two different rhizobacteria inoculant application methods (seed applied method and soil applied method) and three different periods of sowing after inoculation (0 min, 15 mins and 30 mins) in all possible combinations (six treatment The obtained results revealed that Bambara groundnut cultivated on soils fertilized with ten grams of rhizobacteria inoculant per planting hole significantly (p < 0.05) had highest vegetative growth, number of nodules per plant and yield traits in both planting season. The main effect of time of sowing indicated that plants sown 30 minutes after inoculation significantly (p < 0.05) gave the tallest plants and leaf area index per plant in 2015 and 2016 planting season than the other time regime. The interaction effect of rhizobacteria inoculant application methods and time of sowing after inoculation were observed to be significant (p < 0.05) in 2015 and 2016 planting season. The results showed that the plants on soil with combined use of soil applied method of inoculation treatment and 30 minutes after inocualtion before planting significantly (p < 0.05) had the highest vegetative growth, number of nodules per plant and yield parameters than the other interaction effect. The combined use of soil applied method of inoculation treatment and 30 minutes after inocualtion before planting is recommended for the cultivation of Bambara groundnut in Agbani Area South East Nigeria.
Production of tomato in the tropics especially in Ghana is beset with lots of setbacks thereby causing low yields per hectare. Greenhouse cultivation systems are promising yet yields of tropical tomato cultivars are hampered by adverse temperature conditions. In order to mitigate this, an experiment was conducted during the extreme summer temperature conditions in the greenhouse at Kashiwanoha Campus of Chiba University, Japan. The study was conducted between May 23, 2018 and September20, 2018. The low substrate volume production system of 500mL in closed recirculated hydroponics (sub-irrigation) method was employed. Three tropical tomato cultivars (Jaguar, Lebombo and Lindo) were evaluated for yields. Plants were spaced at 20cm (4.2 plants m-2) and 30cm (2.8 plants m-2). At 7 and 9WAT, plants were topped at 2nd and 4th nodes respectively. The 3x2x2 factorial in Randomised Complete Block design in three replications was adopted. Some parameter collected were; 1. Morphometrics such as plant height, girth, leaf number and chlorophyll content, days to 50% flowering and fruit set 2. Yield components and fruit quality such as fruit number, marketable yield, yield per area, yield per hectare, percent blossom end rot, fruit TSS, TA, TSS/TA ratio and 3. Dry matter partitioning at last harvest, 11WAT. Results showed that blossom end rot reduced the yields of Jaguar and Lindo almost by 50% while Lebombo recorded less than 1%. Lebombo produced significantly the highest plant dry mass of 125g of which 57.7% was converted to vegetative growth compared to the Jaguar. For Jaguar however, 53.7% of total plant dry mass was allocated to fruits. This in effect was translated to the highest yield of 93tons ha-1 year-1 for Jaguar plants that were pinched at 4th truss in high density planting of 4.2 plant m-2.
The effect of leguminous cover crops on growth and yield of tomatoAI Publications
Tomato (Lycopersicon esculentum L.) is one of the vegetable fruit crops commonly cultivated around the globe and used mostly as a flavour in cuisines. Cover cropping is a form of sustainable agriculture which helps to maintain soil fertility and reduces the need and the amount of inorganic fertilizer and thus helps the farmer to increase profitability. The objective of this study was to find the effect of the cover crops on growth and yield of tomato. In this experiment legume cover crops were grown in five treatment plots and these were Bare soil, inorganic fertilizer (NPK 15:15:15), Vigna unguiculata (Cowpea), Mucuna pruriens (Mucuna) and Canavalia ensiformis (Canavalia) in 3 blocks. The results showed that tomato plants grown on Canavalia ensiformis plots showed earlier flowering and fruiting than the other treatments. It also showed significantly higher yield than the other treatments (P= 0.006). The study shows that cover crops especially Canavalia ensiformis could be considered as part any farming system that wants to use sustainable farming to improve soil nutrients and reduce cost of farming.

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.

Cassava (Manihot esculenta Cruntz.) establishment depends on quality of planting materials. The experiment was done to determine the effects storage and variety on crop establishment and early growth vigour. Karembo and KME 4 varieties were stored in clamp under double shade (CUDS), horizontal under shade (HUS), vertical under shade (VUS) and horizontal under open ground (HOUG) as control for 16 weeks. Planting materials was sampled from each storage methods after every 4 weeks and taken to field to evaluate their sprouting ability, number of primary shoots formation, number of leaves, rate of leaf formation and early growth vigour. Data were subjected to ANOVA and means separated by LSD. Sprouting percentage at Kabete was 54.73 % while in Kiboko had 37.78 %. The results showed that Kabete had 1.60 number of primary shoots per plant compared to 1.04 of Kiboko. The results showed KME4 had higher sprouting than Karembo in both sites. This can be due to genetic difference among varieties. The rate of leaf formation at Kiboko was higher as compared to Kabete it could be contribute difference in temperature between locations. Thus, optimum temperature and relative humidity should be factored in cassava cuttings storage to avoid increased death of stored cuttings. In case of storage cassava cuttings, should be stored in clamp under double shade methods under low temperature and moderate RH.
Genetic and Morphological Diversity Analysis of Ethiopian Mustard (Brasica ca...Premier Publishers
Growing of Ethiopian mustard, as an oilseed and leaf vegetable require genetic improvement which relies on its genetic diversity. The experiment was executed to analyse genetic and morphological diversity of Ethiopian mustard land races at Holetta agricultural research center. Forty-nine genotypes collected from different agro ecologies were analyzed using morphological traits in order to assess the genetic and morphological diversity that exists in these materials. The experiment was carried out in a simple lattice design. The analysis of variance showed that there were significant differences among genotypes for all traits compared except seed yield per plant, fresh leaf biomass per plant topped at 40, 50 and 60 days of growth and number of intact leaves at flowering. The significant difference indicates the existence of genetic variability among the accessions that is important for selection and breeding. For yield component traits, high genotypic and phenotypic coefficient of variations was observed in seed yield per plot and oil yield. This shows that selection of these traits based on phenotype, may be useful for yield improvement. The highest heritability in broad sense was recorded for thousand seed weight(68.80%), followed by days to flowering (65.91%), stand percent (63.14%), linolenic acid (62.58%), days to maturity(60.43%), plant height (59.63%), palmitic (58.19%), linoleic (57.46%),leaf area (52..09%), oil content (50.33%), leaf width (48.29%),leaf length(46.28%), oil yield(44.84%), fresh leaf biomass at 50 days of topping(43.40%), seed yield per plot(42.99%), number of leaves at vegetative state(40.48%), seed yield of 50 days growth stage topped plants(38.85%) and primary branches (34.20%). This suggests that large proportion of the total variance was due to high genotypic variance. Hence, a good progress can be made if some of these traits are considered as selection criteria for the improvement of yield, yield component and vegetative traits. The present study revealed the presence of considerable variability among genotypes for all traits compared except seed yield per plant, fresh leaf biomass per plant topped at 40,50 and 60 days of growth and number of intact leaves at flowering. These conditions indicate that there is good opportunity to improve these characters using the tested genotypes.

A field experiment was conducted during 2004 and 2005 cropping seasons to determine effect of different weed control practices on proximate composition, nutrient concentration and nutrient uptake of maize (Zea maysL.) at the Teaching and Research Farm of Ambrose Alli University, Ekpoma, Nigeria. Seven treatments were used for the experiment, viz no weeding (control), Primextra (3.0kg a.i./ha), mulching (wood shavings), one- hoe weeding at 3 weeks after planting (WAP), two hoe- weedings at 3 and 7 WAP, cover cropping with melon minus hoe-weeding, cover-cropping with melon plus one hoe-weeding at 3WAP. The seven treatments were laid out in randomized complete block design with four replicates. Results showed that mulched plot with wood shavings had the lowest weed density and highest proximate composition, grain nutrient concentration, ear leaf concentration and nutrient uptake followed by Primextra treated plot .The study recommends that small holder farmers to adopt mulching technique with wood shaving to improve the nutritional quality of maize grain since it does not involve any technical rigor besides signifying a non-chemical weed control.

It was conducted at Cagayan State University – Piat Campus from September to October 2019. The Completely Randomized Design (CRD) with four replications was used to test the following treatments: T1 – Rockwool, T2– Coco peat, T3 – Carbonized Rice Hull (CRH) and T4 – Sawdust. Results show that plants under coco coir (T2)–obtained the tallest and longest roots while the most number of leaves and heaviest fresh biomass was registered in rock wool (T1). In terms of water pH, the result revealed no significant differences among treatment means. In the absence of rock wool, the coco coir can be used as an alternative as growing substrates for a non-circulating hydroponics system since they did not differ significantly.
Effect of Different Sources of Nutrient on Growth and Yield of Okra (Abelmosc...Agriculture Journal IJOEAR
The experiment was carried out at Nepal Polytechnic Institute field, Bharatpur, Chitwan, Nepal to study the effect of different nutrient sources on growth and yield of okra (Abelmoschus esculentus L Monech). Five different treatments; poultry manure, FYM, goat manure, chemical (as per N equivalent) and no fertilizer (control) were replicated four times. The experiment was arranged in Randomize Complete Block Design (RCBD). The okra variety ArkaAnamika was used for experiment. The data were collected on the growth and yield parameters including plant height (cm), canopy (cm), numbers of leaves per plant, numbers of branches per plant, fruit length, diameter and yield. Results indicated that different nutrient sources had significant (P<0.05) affected on plant height, canopy, leaf number, branches and also in yield parameters. Based on the findings of the experiments, it can be concluded that application of poultry manure significantly increased the growth and yield performances on Abelmoschus esculentus L. Monech (okra) compared to other types of fertilizers. As the study reflected the use of no fertilizer results in the lowest vegetative growth and yield performances which indicates to use some nutrient sources for better growth and production of okra.
Glyphosate resistance trait into soybean Cuban varieties: agronomical assessm...Innspub Net
Glyphosate-resistant (GR) soybean was one of the first major applications of genetic engineering in field crops and offered farmers a vital tool in fighting weeds. Weeds are a problem for soybean production in Cuba, so our work aim was the GTS 40-3-2 event introgression into Cuban varieties. Two local cultivars were crossed with transgenic genotypes that carry the event. From F1 to F3 generations, individual plants that produced more than 60 g of seeds per plant were chosen to obtain next generation. Individual lines were selected from F4 generation. F5 and F6 generations of five selected transgenic lines and their relatives were chosen to evaluate seven
agronomic traits throughout the summers of 2012 and 2013. A Random Block experimental design was done. First flowering (R1) and maturity (R8) stages of all genotypes were affected by planting date. Plant height of I1B2- 3, I1B4, I36B4 and RP5 lines ranged from 80 to 111 cm. I1B2-2 and I1B2-3 lines would be suitable for mechanized harvesting because they had the insertion of the first pod at 14.63 cm and 13.93 cm respectively. I36B4 line produced the greatest number of pods per plant (127). Transgenic lines produced more than 180 seeds per plant and 100-seed weight ranged from 13.75 g to 17.46 g. Seed yield per plant of transgenic lines and their parents IncaSoy36, CEB2 and CEB4 weren’t statistically different. These results could be a start point for other studies
involving larger areas, different planting dates and localities. Get more articles at: http://www.innspub.net/volume-7-number-4-october-2015-ijaar/

The main objective of this study is determine the responses of Bambara groundnut [Vigna subterranea (L). Verdc.] to application methods of plant growth promoting rhizobacteria inoculant and time of sowing after inoculation in Agbani area of Enugu, South East Nigeria. Field trials were conducted at the Teaching and Research Farm of the Faculty of Agriculture and Natural Resources management, Enugu State University of Science and Technology in 2015 and 2016 planting season. The experiment was a 2 × 3 factorial trial in a randomized complete block design with three replications. The treatments consisted of two different rhizobacteria inoculant application methods (seed applied method and soil applied method) and three different periods of sowing after inoculation (0 min, 15 mins and 30 mins) in all possible combinations (six treatment The obtained results revealed that Bambara groundnut cultivated on soils fertilized with ten grams of rhizobacteria inoculant per planting hole significantly (p < 0.05) had highest vegetative growth, number of nodules per plant and yield traits in both planting season. The main effect of time of sowing indicated that plants sown 30 minutes after inoculation significantly (p < 0.05) gave the tallest plants and leaf area index per plant in 2015 and 2016 planting season than the other time regime. The interaction effect of rhizobacteria inoculant application methods and time of sowing after inoculation were observed to be significant (p < 0.05) in 2015 and 2016 planting season. The results showed that the plants on soil with combined use of soil applied method of inoculation treatment and 30 minutes after inocualtion before planting significantly (p < 0.05) had the highest vegetative growth, number of nodules per plant and yield parameters than the other interaction effect. The combined use of soil applied method of inoculation treatment and 30 minutes after inocualtion before planting is recommended for the cultivation of Bambara groundnut in Agbani Area South East Nigeria.
Production of tomato in the tropics especially in Ghana is beset with lots of setbacks thereby causing low yields per hectare. Greenhouse cultivation systems are promising yet yields of tropical tomato cultivars are hampered by adverse temperature conditions. In order to mitigate this, an experiment was conducted during the extreme summer temperature conditions in the greenhouse at Kashiwanoha Campus of Chiba University, Japan. The study was conducted between May 23, 2018 and September20, 2018. The low substrate volume production system of 500mL in closed recirculated hydroponics (sub-irrigation) method was employed. Three tropical tomato cultivars (Jaguar, Lebombo and Lindo) were evaluated for yields. Plants were spaced at 20cm (4.2 plants m-2) and 30cm (2.8 plants m-2). At 7 and 9WAT, plants were topped at 2nd and 4th nodes respectively. The 3x2x2 factorial in Randomised Complete Block design in three replications was adopted. Some parameter collected were; 1. Morphometrics such as plant height, girth, leaf number and chlorophyll content, days to 50% flowering and fruit set 2. Yield components and fruit quality such as fruit number, marketable yield, yield per area, yield per hectare, percent blossom end rot, fruit TSS, TA, TSS/TA ratio and 3. Dry matter partitioning at last harvest, 11WAT. Results showed that blossom end rot reduced the yields of Jaguar and Lindo almost by 50% while Lebombo recorded less than 1%. Lebombo produced significantly the highest plant dry mass of 125g of which 57.7% was converted to vegetative growth compared to the Jaguar. For Jaguar however, 53.7% of total plant dry mass was allocated to fruits. This in effect was translated to the highest yield of 93tons ha-1 year-1 for Jaguar plants that were pinched at 4th truss in high density planting of 4.2 plant m-2.
The effect of leguminous cover crops on growth and yield of tomatoAI Publications
Tomato (Lycopersicon esculentum L.) is one of the vegetable fruit crops commonly cultivated around the globe and used mostly as a flavour in cuisines. Cover cropping is a form of sustainable agriculture which helps to maintain soil fertility and reduces the need and the amount of inorganic fertilizer and thus helps the farmer to increase profitability. The objective of this study was to find the effect of the cover crops on growth and yield of tomato. In this experiment legume cover crops were grown in five treatment plots and these were Bare soil, inorganic fertilizer (NPK 15:15:15), Vigna unguiculata (Cowpea), Mucuna pruriens (Mucuna) and Canavalia ensiformis (Canavalia) in 3 blocks. The results showed that tomato plants grown on Canavalia ensiformis plots showed earlier flowering and fruiting than the other treatments. It also showed significantly higher yield than the other treatments (P= 0.006). The study shows that cover crops especially Canavalia ensiformis could be considered as part any farming system that wants to use sustainable farming to improve soil nutrients and reduce cost of farming.

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.
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 storage methods of cassava planting materials on establishment and ...Innspub Net
Cassava (Manihot esculenta Cruntz.) establishment depends on quality of planting materials. The experiment was done to determine the effects storage and variety on crop establishment and early growth vigour. Karembo and KME 4 varieties were stored in clamp under double shade (CUDS), horizontal under shade (HUS), vertical under shade (VUS) and horizontal under open ground (HOUG) as control for 16 weeks. Planting materials was sampled from each storage methods after every 4 weeks and taken to field to evaluate their sprouting ability, number of primary shoots formation, number of leaves, rate of leaf formation and early growth vigour. Data were subjected to ANOVA and means separated by LSD. Sprouting percentage at Kabete was 54.73 % while in Kiboko had 37.78 %. The results showed that Kabete had 1.60 number of primary shoots per plant compared to 1.04 of Kiboko. The results showed KME4 had higher sprouting than Karembo in both sites. This can be due to genetic difference among varieties. The rate of leaf formation at Kiboko was higher as compared to Kabete it could be contribute difference in temperature between locations. Thus, optimum temperature and relative humidity should be factored in cassava cuttings storage to avoid increased death of stored cuttings. In case of storage cassava cuttings, should be stored in clamp under double shade methods under low temperature and moderate RH.
Genetic and Morphological Diversity Analysis of Ethiopian Mustard (Brasica ca...Premier Publishers
Growing of Ethiopian mustard, as an oilseed and leaf vegetable require genetic improvement which relies on its genetic diversity. The experiment was executed to analyse genetic and morphological diversity of Ethiopian mustard land races at Holetta agricultural research center. Forty-nine genotypes collected from different agro ecologies were analyzed using morphological traits in order to assess the genetic and morphological diversity that exists in these materials. The experiment was carried out in a simple lattice design. The analysis of variance showed that there were significant differences among genotypes for all traits compared except seed yield per plant, fresh leaf biomass per plant topped at 40, 50 and 60 days of growth and number of intact leaves at flowering. The significant difference indicates the existence of genetic variability among the accessions that is important for selection and breeding. For yield component traits, high genotypic and phenotypic coefficient of variations was observed in seed yield per plot and oil yield. This shows that selection of these traits based on phenotype, may be useful for yield improvement. The highest heritability in broad sense was recorded for thousand seed weight(68.80%), followed by days to flowering (65.91%), stand percent (63.14%), linolenic acid (62.58%), days to maturity(60.43%), plant height (59.63%), palmitic (58.19%), linoleic (57.46%),leaf area (52..09%), oil content (50.33%), leaf width (48.29%),leaf length(46.28%), oil yield(44.84%), fresh leaf biomass at 50 days of topping(43.40%), seed yield per plot(42.99%), number of leaves at vegetative state(40.48%), seed yield of 50 days growth stage topped plants(38.85%) and primary branches (34.20%). This suggests that large proportion of the total variance was due to high genotypic variance. Hence, a good progress can be made if some of these traits are considered as selection criteria for the improvement of yield, yield component and vegetative traits. The present study revealed the presence of considerable variability among genotypes for all traits compared except seed yield per plant, fresh leaf biomass per plant topped at 40,50 and 60 days of growth and number of intact leaves at flowering. These conditions indicate that there is good opportunity to improve these characters using the tested genotypes.

Effect of different Mulching Materials on the Yield of Quality Protein Maize ...Agriculture Journal IJOEAR
— Field research was conducted on the effects of different mulching materials on the yield of Quantity protein maize which include polythene sheet, dry grasses and control. The different mulching materials were tested on nine (9) ridges each measuring 10m. The research was laid out in a completely randomized block design each treatment replicated three times. The parameters measured include weight of cobs, weight of 100grain, and total grain, there was no statistical difference in the weight cobs among all the treatments, similarly, there was also no statistical different in the weight of 100 grain. As far the weight of grain per 5m 2 there was a significant difference among the treatments with polythene sheet covered plots that have 0.25kg, however, the grass-mulched plots 0.16kg was statistically similar to the control plots 0.15kg. And finally for store weight observed per 5m 2 , polythene sheet covered plots were significantly higher than grass-mulched plots which are also significantly different to control plots with the values of 1.23kg, 1.21kg and 0.71kg respectively.

Climate and crop modeling by Gummadi Sridhar,Gizachew Legesse,Pauline Chiveng...ICRISAT
Climate effects on agriculture are of increasing concern in both the scientific and policy communities because of the growing population and the greater uncertainty in the weather during growing seasons. Changes in production are directly linked to variations in temperature and precipitation during the growing season and often to the offseason changes in weather because of soil water storage to replenish the soil profile. This is not an isolated problem but one of worldwide interest because each country has concerns about their food security.
I'm Charlie Nardozzi. People are growing plants in the wildest places these days. There are rooftop gardens sprouting up on top of 30 story buildings, container gardens on balconies and fire escapes, and now living green walls in cities, schools and homes.
The green wall revolution coincides with the increased interest in urban gardening. Gardeners are growing everything in green walls. I saw a school once in Queens that had a living green wall indoors to help purify the air. Many common plants can filter off-gasses emitted by paints and carpets. And you don't have to live in a city for it to make sense. I was at the Coastal Maine Botanic Garden last summer and they have a green edible wall filled with basil and cherry tomatoes. In my latest book, Urban Gardening for Dummies, coauthored with Paul Simon, we devote a whole chapter just to vertical gardening.
Space saving is always a good idea and green wall technology now makes it easier for a home gardener to grow up. To grow a vertical garden at home, you can purchase simple kits with pots that hook on a wire screen that can be mounted to a wall or sophisticated planting devices with drip irrigation and fertilizer systems.
You also can make a simple green, wall garden with old wooden pallets. Here's how. Fix any lose boards and remove protruding nails. Staple landscape fabric around the back and three sides of your pallet. Place plants in the one side that will be the top and then lay the pallet horizontal and fill it with potting soil. Plant transplants in the open slats, mixing flowers, veggies and even strawberries. Let them grow on the ground for a few weeks to get established keeping them well watered, then prop up the pallet to grow vertically.

Irrigation experiments of cocoa tend to concentrate on yield of matured cocoa trees compared to field establishment of young seedlings. Seedling survival leading to optimum population density are fundamental to obtaining maximum yield of crops. The aim of this experiment was to determine the effect of mulching and irrigation on survival of hybrid cocoa clone raised in three different growing media during the establishment phase. The experimental design was a 2 x 2 x 3 factorial arranged in a split-split plot design, with irrigation as the main plot factor, mulching as the subplot factor and growing media as the sub-sub plot factor with three replications. Cocoa pod husk (CPH) was used as the mulching material and each plant received 5kg at a rate of 5.6 t/ha. Irrigation was done daily by applying 4L of water except when it rains. Data was collected on soil moisture, plant height, leaf number, stem girth and plant survival. Results indicated that irrigation and mulching significantly (P<0.01) enhanced soil moisture. Cocoa seedlings raised in topsoil, mulched and irrigated significantly (P<0.05) increased survival rate (94.5%) compared to seedlings raised in soil without irrigation and no mulching (47.1%). Similarly, the survival rate of seedlings raised in growing media M2, mulched and irrigated (93.0%) was significantly (P<0.05) higher than similar seedlings without irrigation (73.4%). However, the survival rate of seedlings raised in M3 without mulching but irrigated was significantly (<0.05) higher 92.1% compared to seedlings raised in M3 mulched and irrigated 67.1%. Irrigation is very important in ensuring high survival rate during early field establishment. Mulching with cocoa pod husk without irrigation did not improve cocoa seedling survival.

The Effect of Mulching on Soil Moisture Retention and Yield of Lettuce (Lactu...Agriculture Journal IJOEAR
An experiment was conducted to evaluate the effectiveness of different mulching materials on soil moisture retention and yield of lettuce at the greenhouse located at Luyengo campus of the University of Eswatini during the months of January and February, 2019. The treatments consisted of grass mulch (GM), Plastic mulch (PM), leaf debris mulch (LM), and no mulch (NM) which was used as a control. Each of the treatments had four replications. The organic mulch was applied at a thickness of 10 cm, and the plots for experiments were randomly selected. Each plant received 600 cm 3 of water every 3 days using a homemade drip irrigation system (equivalent to 6 mm per irrigation circle). Data on soil moisture content was collected using the gravimetric method every 3 days (before irrigation).The growth parameters of the lettuce plants that were collected weekly were plant height, leaf number and leaf area. Both wet weight and dry weight yield were determined for each plot at the end of the experiment (six weeks after planting). Data collected was coded and entered into SPSS computer software. Data analysis was conducted using the analysis of variance (ANOVA) and the least significance difference (LSD) test to determine if means were significantly different. The results showed that GM treatment had high mean moisture retention at 9.3%. It was followed by PM and LM at 8.9%. The lowest moisture retention was realized from the control (No mulching) at 7.9%.The differences in mean moisture retention was significant between NM and NM (p<0.05). The same pattern was observed for the growth parameters, where GN had highest values and the control had the lowest values. The wet mass yield was highest for GM, at 164.7 g. The yield from LM was 149.3 g. It was followed by PM at 141.3 g. The lowest yield was obtained from the control at 108 g. The difference in mean yields for GM and NM were significant (p<0.05). They were not significantly different for all the other treatments (p>0.050. It was concluded from the experiment that grass mulching resulted in improved moisture retention and high yields.
High ambient temperature is the greatest problem faced by tropical greenhouse producing
vegetables. Temperature affects the productivity and growth of a plant, therefore using shades to alleviate this
effect could increase the yield of plants grown in greenhouses. This study intends to investigate the effect of
shading and greenhouse conditions on brinjal flowering and traits, and subsequently compare them to open
field cultivation of brinjal.
Fertility Levels of Soils under Selected Tree Vegetations for Efficient Agro-...AI Publications
In many parts of Nigeria, large areas of lands are dominated by tree crop vegetations for timber production and for fruits with land users not knowing the fertility status of soils in these vegetations. Continual evaluation of soil properties of these tree vegetations has become pertinent for agricultural sustainability. This study therefore was carried out to evaluate the fertility levels of soils under selected tree vegetations at National Horticultural Research Institute Okigwe, Imo State, Nigeria. Five tree vegetations that were over 20 years of establishment were selected namely: oil bean (Pentaclethra macrophylla Benth), African breadfruit (Treculia africana), mango (Mangnifera indica), Ogbonu (Irvingia gabonensis) and orange (citrus spp). In each of these tree vegetations, four soil samples were collected at uniform depths (0 – 20, 20 – 40 and 40 – 60 cm) at different locations using soil auger. The samples were analyzed using standard laboratory procedures. Data collected were statistically analyzed using analysis of variance. Results obtained showed that despite the ages of these vegetations, the soils were acidic, low in macronutrient and basic cation concentrations when compared to FAO standard. The highest exchangeable bases and organic matter (1.78%) was recorded on bread fruit vegetation. Therefore, there is need to increase the fertility status of these soils in these tree crop vegetations by adopting measures that will boost organic matter content of the soil irrespective of the duration of the vegetation and this will help in agro forestry and alley cropping.
Dynamic Assessment of Air Temperature for Tomato (Lycopersicon Esculentum) Cu...Redmond R. Shamshiri
Net-screen covered greenhouses operating on natural ventilation are used as a sustainable approach for closed-field cultivation of fruits and vegetables and to eliminate insect passage and subsequent production damage. The objective of this work was to develop a real-time assessment framework for evaluating air-temperature inside an insect-proof net-screen greenhouse in tropical lowlands of Malaysia prior to cultivation of tomato. Mathematical description of a growth response model was implemented and used in a computer application. A custom-designed data acquisition system was built for collecting 6 months of air-temperature data, during July to December 2014. For each measured air-temperature (T), an optimality degree, denoted by Opt(T), was calculated with respect to different light conditions (sun, cloud, night) and different growth stages. Interactive three-dimensional plots were generated to demonstrate variations in Opt(T) values due to different hours and days in a growth season. Results showed that, air temperature was never less than 25% optimal for early growth, and 51% for vegetative to mature fruiting growth stages. The average Opt(T) in the entire 6 months was between 65 and 75%. The presented framework allows tomato growers to automatically collect and process raw air temperature data and to simulate growth responses at different growth stages and light conditions. The software database can be used to track and record Opt(T) values from any greenhouses with different structure design, covering materials, cooling system and growing seasons, and to contribute to knowledge-based decision support systems and energy balance models.
Screening and Selection of Drought-Tolerant Groundnut Varieties Based on Yiel...Premier Publishers
Drought is the most important abiotic limitation to groundnut production in Northern Ghana. Drought, during the pod-filling stages is even more devastating. The current study was conducted to screen groundnut varieties, for drought-tolerance based on yield and other traits. Evaluation of groundnut genotypes was under two environments/water regimes; well-watered and water-stressed. ANOVA was run for Quantitative data. Means were separated by l.s.d. at 95% confidence level. Correlation analyses were performed using SPSS. Combined analysis of variance was computed for the groundnuts across water regimes. Dendrograms were generated using yield data and based on Euclidean distance. Scoring and ranking was used to assess disease incidence on a scale of 1-5. Results indicate that end-of-season drought caused pod yield reduction that varied across genotypes. The Drought Tolerance Index ranged from 0.53 (Kpanieli) to 2.40 (Agric-Manipinta). The highest yielding genotypes under water-stressed condition were Sinkara (582g/plot), Nkatie-sari (512g/plot), Ndogba (470g/plot), Chaco-pag (400g/plot) and Oboshie (381g/plot) and Chinese (local) (340g/plot). Farmers’ selected Sinkara, Ndogba, Chinese, Nkatie-sari, Agric-Manipinta and Chaco-pag based on pod yield and biomass production. Sinkara (0.8798), Sokan-donworor (0.8739), Kpach-Isah (0.8318) and Kpanieli (0.8016) recorded very high mean pod harvest index values, while Ndogba recorded the lowest (0.2252). Combined analysis of variance for pod yield among all the genotypes indicate that the groundnuts performed differently in both water regimes due to the significant interaction effect observed between water regimes and genotypes. Information generated from this study can be used to develop new groundnut varieties that combine higher yield and drought tolerant traits.
Development of drought tolerant maize cultivars is prerequisite to achieving stable grain yield in
drought–prone ecologies of Nigeria’s Guinea savanna. However, success has been limited mainly due
to lack of maize genotypes that show clear differences in response to well defined moisture deficit
condition. Two sets of drought tolerant (DT) maize germplasm were evaluated under screenhouse and
field conditions between 1999 and 2002. In the screenhouse study, performances of the genotypes
were compared under well-watered condition and moisture deficit imposed at different growth stages.
Under field conditions, the first set comprising 11 accessions along with a check were evaluated for 4
growing seasons while the second set which comprised 3 DT varieties were evaluated along with 2
check varieties using monthly plantings between April and August of 2001 and 2002, respectively. In
the first set, post anthesis moisture deficit significantly reduced grain yield by 25 to 73.5% in the open
pollinated varieties (OPVs) and by 20 to 64% in the hybrids. Grain yield under field conditions ranged
from 2.48 to 3.49, 2.82 to 3.73 and 3.58 to 4.76 tons/ha-1 for 1999, 2000 and 2001 full growing seasons,
respectively, and 2.03 to 2.50 tons/ha-1 for 2000 late growing season. In the second set, pre and post
anthesis moisture deficits reduced grain yield by 77.6 and 95.8%, respectively, of well watered
condition while in the field, grain yields in the genotypes were highest for plantings made in April and
July (1.90 - 2.5 t/ha), lowest for August (0.7 -1.8 t/ha) when moisture deficit coincided with
reproductive phase. Yield stability exhibited under moisture deficit and on the field by 8522-2, Oba
super 2 and AK9943-DMRSR in the first set as well as DT-SR-Y C0 and DT-SR-W C0 in the second set,
indicates their suitability either as cultivars per se or as potential source of DT alleles for
development of DT maize varieties for Nigeria’s savanna ecologies.
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.
Mulching and Tied Ridges as A Moisture Conservation Strategy to Improve the Y...Agriculture Journal IJOEAR
Abstract— An experiment was conducted to determine the effectiveness of soil moisture conservation techniques on improving sorghum yield in a semi-arid rural area of Swaziland. The four treatments were; planting sorghum on flat soil (F), planting on tied ridges (T), planting on mulched soil (M) and planting on a combination of tied ridges and mulch (TM). Sorghum planted on flat soil was used as control in the experiment. The sorghum variety 8625 was planted. The experiment was complete randomized design and each treatment was replicated three times. The parameters measured were; grain yield, total biomass yield, soil moisture suction and grain moisture content at harvest. The grain yields from all the other treatments (mulching, tied ridges, tied ridges with mulching) were higher than those of the control (flat planting). The grain yield from TM was the highest at an average of 10.002 tons/ha. It was significantly different from that of T and F (p<0.05).>0.05). The results showed that a combination of tied ridges and mulching provided superior results in terms of grain yield, dry matter yield and soil moisture suction. Mulching and tied ridges also yielded results that were better than the control (F).
Changes in Selected Soil Physical Properties and Maize Yields as Affected by ...IJEAB
The study was conducted at Abakaliki to determine the changes in selected soil physical properties and maize yields as affected by animal wastes application in Abakaliki southeastern Nigeria in 2014 and 2015 cropping seasons. The experiment was laid out in Randomized Complete Block Design with four treatment replicated five times. The treatments were poultry droppings at 5 tha-1 (PD), cow dung at 5 tha-1 (CD), mixture of PD + CD at 5 tha-1 and control (C) – non application of amendment. Bulk density, total porosity, moisture content, aggregate stability and mean weight diameter were determine in the laboratory using appropriate procedure while plant height, leaf area index and grain yield were also, measured in the field using recommended methods. The results showed positive changes in selected soil physical properties and maize yield in the two cropping seasons with the application of animal wastes. Also, improvement in soil physical properties and maize yields were higher in the second cropping season when compared to the first cropping season. Poultry dropping is recommended for farmers to use as fertilizer in maize production because plots treated with poultry droppings recorded the highest maize grain yield in the two cropping season than other treatments.
An experiment was carried out to determine the effect of different organic manure on the growth yield and nutritive value of Guinea grass (Panicum maximum). This experiment was designed in a Randomized Complete Block Design with three replicates. Treatments were control (without any manure) (T 1), Goat manure alone (25 t ha -1) (T 2), Poultry manure alone (25t ha -1) (T 3), Cattle manure alone (25 t ha -1) (T 4). These were applied as basal and topdressing application of manure in this experiment and their performance was recorded once in three weeks. Analysis of Variance was performed to define a significant difference among treatments (p < 0.05). Results revealed that plants grown in Poultry manure (T3 )(25 t ha -1) showed significantly (p < 0.05) better performance in the measured growth parameters viz. plant height(217.2cm), leaf area, number of tillers, maximum leaf length and maximum leaf width while the lowest performance was observed in control (T1) at 11 WAP( weeks after planting). Further the results of this study revealed that relatively higher total dry matter (149.61g/plant) and nutrition composition viz crude protein (14.48%), Ash content(19.78%),crude fiber(16.17%), Ether extract (8.75%) was obtained from the plants treated with poultry manure alone (T3) followed by T4,T2 whereas the lowest dry-matter yield(62.7g/plant) and nutrition composition was observed in control (T1). Therefore, it could be concluded that the poultry manure can be used to enhance the growth and nutritive value of Guinea grass.
Wheat is a temperate crop requiring low temperatures for growth and yield. Production of wheat in the Sudan savanna agro-ecological zone of Nigeria is restricted to periods of low temperatures that prevailed from early November to late February. Based on the above, field experiments were conducted in two locations at the University Teaching and Research Farm during 2016/2017 dry season to determine the most appropriate planting date and planting method in the study area. The two locations were: Fadama Teaching and Research farm at Jega (Lat. 12°12.99' N; long. 4° 21.90'; 197m above sea level) and the University orchard at Aliero (lat. 12°18.64'N; long. 4°29.85'; 262 above sea level). Both Jega and Aliero are located within Sudan Savanna ecological zone of Nigeria. Treatments consisted of factorial combinations of four Planting dates (1st November, 15th November 1st December and 15th December 2016) and three Planting Methods (Drilling, Dibbling and Broadcasting). The experiments were laid out in a Randomized Complete Block Design (RCBD) with three replications. Results revealed that grain number per spike; grain weight per spike, 1000-grain weight, straw yield, and grain yield were higher when planted on 15th November and 1st December. On the other hand, drilling and dibbling methods resulted to higher stand count, plant height, leave number, leaf area index, days to 50% heading, grain number per spike, grain weight per spike, 1000-grain weight straw and grain yields than broadcasting method. Based on the results of this study, it could be concluded that planting of wheat from 15th November to 1st December coupled with either dibbling or drilling methods of planting gives the best wheat yield in the study area.
