Increasing cassava productivity through optimized planting dates, crop age at harvest and fertilizer application

The document summarizes Monsanto's 2014 pilot cover crop program for seed growers in Oelwein. The program shared costs of cover crop seed to encourage growers with limited experience to adopt the practice. Participants provided field data. The proposed benefits of cover crops discussed are long-term soil health, erosion control, nutrient scavenging, and addressing compaction issues. The summary provides examples of cover crop planting methods, mixtures, and timing used in the program and discusses establishment success, challenges from weather and timing, and best practices identified.

Brothers Jake and Blake Drenon are using grid sampling technology and GPS-assisted variable rate fertilizer application on their cattle operation in Missouri. Grid sampling creates a detailed soil profile that shows fertility strengths and weaknesses across their land. This allows them to variably apply fertilizer based on each area's needs, increasing productivity while reducing over-application and costs. They have seen a 20-30% increase in carrying capacity through this innovative approach. The article promotes grid sampling as a tool for young beef producers to boost profitability now and in the future.

Variation in Corn Yield across Planter Width

DuPont Pioneer

The study found that corn yield varied across planter width, with the outside wing harvest passes yielding significantly more than the center passes at most locations, averaging 11.3 bushels per acre more. This confirms that soil compaction from planter wheels in the interrows can reduce corn yield in adjacent rows. Splitting planters into more than two strips for trials could unfairly bias results due to differential wheel traffic impacts. Growers should be aware of potential yield effects of compaction when setting up split-planter comparisons.

African Conservation Tillage Network

- The Foundations for Farming system is a conservation agriculture approach developed for small-scale African farmers to improve yields and profits using appropriate technology. It focuses on minimal soil disturbance, mulching for moisture retention, and crop rotations. - Key findings from research and development trials show that organic fertilizers like manure and compost can provide comparable yields to inorganic fertilizers when used properly. Crop rotations, particularly maize-soybean-maize, have resulted in maize yields of 7 tons/hectare without any fertilizer application. - Current research is focusing on improving soybean yields on sandy soils through inoculation and developing integrated farm models combining crops and livestock.

DuPont Pioneer conducted corn population research trials across North America from 2001-2012. The results showed that the optimal seeding rate depends on yield levels, with higher rates needed for higher yields. For typical Midwest yields of 190-220 bushels per acre in 2013, the optimal economic seeding rate was found to be 34,600 seeds per acre. Hybrid improvements have allowed for higher populations over time, with the top yielding hybrids from 2009-2012 performing best at 40,000 plants per acre. Growers can use these results to determine the best seeding rates for their hybrids, locations, and management practices.

SRI-Rice, Dept. of Global Development, CALS, Cornell University

Willem A. Stoop presents on ecological intensification lessons learned from the System of Rice Intensification (SRI). He discusses two approaches to intensification - conventional using modern varieties, dense planting, irrigation, and chemicals, and ecological using local varieties, low seeding rates, and organic inputs. SRI is presented as an example of an agro-ecological approach using practices like young seedlings, wide spacing, and alternate wetting and drying of soils. SRI results in increased growth, yields, and resilience through enhanced root and soil biology. However, SRI challenges conventional agricultural sciences' focus on increasing planting densities and fertilizer use over soil health and plant spacing.

Alexander Decker

This study evaluated the effects of row spacing and fertilizer rates on yield and growth of transplanted tef in Ethiopia over two growing seasons. Four row spacings (15cm, 20cm, 25cm, 30cm) and two fertilizer rates (100/100 and 50/100 kg/ha of urea/DAP) were tested. Transplanting tef resulted in 29.2-39.3% higher yields than broadcasting. The highest grain yield of 24.4 Q/ha was obtained with a row spacing of 15cm. Applying 100 kg/ha of urea produced more tillers and higher yields than 50 kg/ha. The optimum row spacing and fertilizer rate for transplanted tef

1. The document summarizes a seminar presentation on the Sustainable Sugarcane Initiative (SSI), an agronomic approach inspired by SRI rice methods that aims to increase sugarcane productivity using fewer resources. 2. Major principles of SSI include raising nurseries with single-budded chips, transplanting young seedlings in zig-zag patterns with wider spacing, precision water management including drip irrigation, reduced chemical fertilizer and pesticide use, and intercropping. 3. Studies show SSI can increase yields to 100-130 tons/hectare, save 40% water usage, and increase profits by 30% compared to conventional methods through greater resource efficiency and healthier soil/

Elevated atmospheric CO2 and wheat production in Australia - Glenn Fitzgerald

Climate Change Research Strategy for Primary Industries

The document discusses research on the impacts of elevated CO2 levels on wheat production in Australia. Key findings include: - Wheat grown under elevated CO2 (550 ppm) at two sites in Australia showed yield increases of 22-61% depending on location and year. More stimulation was seen at the drier location. - Elevated CO2 decreased grain protein levels by 4-13% but increased nitrogen uptake in straw and grains by 24-63%. This has implications for wheat quality and nitrogen management. - Crop modeling found that despite experimental yield increases under elevated CO2, future changes in rainfall and temperature are predicted to result in yield losses of 10-20% in some regions and gains of 10

1) The document describes research on improving cassava production techniques in Asia, including time and method of planting, weed control, fertilization, intercropping, and erosion control. Experiments showed that yields are reduced if rainfall or temperatures are limiting after 3-5 months of planting. 2) Planting vertically or inclined produces higher yields than horizontally, especially during drought. Planting on ridges is better in rainy seasons but flat planting is better in dry seasons. High yields can be maintained with animal manure and chemical fertilizers or chemical fertilizers alone. Intercropping with peanuts increases income and protects soil. 3) Fertilization, intercropping, contour ridging, and contour he

Conservation agriculture adoption by cotton farmers in eastern zambia

African Conservation Tillage Network

This document summarizes research on the adoption of conservation agriculture (CA) techniques like minimum tillage and mulching by smallholder cotton farmers in eastern Zambia. The researchers surveyed 326 farmers about their land preparation methods for cotton and maize plots. They found that only 5% of plots using the basin method and 13% of ripped plots included legume rotations, and most crop residues were grazed. Statistical modeling showed that adoption of ripping was associated with wealth, oxen ownership, and experience, while basins were used by labor-abundant households. The researchers concluded that basins meet niche needs but large-scale adoption is unlikely, while ripping has more potential if equipment rentals increase and training accompanies expanded

Increasing the Production and Productivities of Groundnut in the Dry Savannas...

ICRISAT

Nigeria has move from one of the major groundnut exporting country to an importing country due to several factors, biotic, abiotic ad social. There is a renewed interest by stakeholders to increase groundnut production in Nigeria. One way is to increase the hectrage of production either in the wet season or through dry season production. Preliminary survey have shown that groundnut cultivation in the dry season for seed, grains or fodder is highly profitable. There is however no scientifically backed recommendation of planting date and variety for this technology. Farmers therefore plant dry season groundnut whenever they fill, some farmers plant too early resulting in stunted growth as a result of low temperature in the early season while others plant late which result in the crop maturing at beginning of rains thereby resulting in conflict with the subsequent wet season crop. This can be addressed by initiating a scientific based research to obtain optimum planting date dates. Another way to increase the grgroundnut production is to improve the agronomic recommendation to facilitate reaching potential yields of the new improved varieties available.

High-Yield Corn Production

DuPont Pioneer

This document summarizes best practices for high-yield corn production based on national corn yield contest winners. Key practices include selecting hybrids with top yield potential, applying nitrogen fertilizer at key growth stages, planting early at optimal populations in 30-inch rows, and using foliar fungicides which increased yields 80% of the time. Contest winners also employed crop rotations, starter fertilizers, and weed control programs utilizing multiple herbicides to manage resistance. Adopting several of these proven practices can help growers accelerate corn yield gains.

Bacterial wilt in irish potato

MohamedManjale

This document presents the background and methodology for a study investigating the susceptibility of different Irish potato varieties to bacterial wilt caused by Ralstonia solanacearum. The study aims to identify high-yielding varieties that are less susceptible to bacterial wilt. The experiment will use a randomized complete block design with four potato varieties (Kenya karibu, Shangi, Dutch robijn, Tigoni) and five replications. Data on days to wilting onset, tuber numbers, weights, and proportion of symptomatic tubers will be collected and analyzed. The results are expected to help breeding programs identify resistant varieties and advise small-scale farmers on high-yielding, less susceptible varieties.
