1. Dryland Organic Winter Wheat Improvement by the Inclusion of Composted Cattle Manure and Cover CropsOrganic agriculture in semi-arid environments can face several challenges in order to produce a successful crop. These include nitrogen and phosphorus deficiencies, moisture limitations, and high weed competition. Organic winter wheat (Triticum aestivum, L.)-fallow systems can be amended with composted cattle manure and with green manure from cover crops grown in the fallow phase to help increase wheat yields and quality. Cattle manure can improve soil health with the... C. Helseth, U. Norton |
2. Effects of Commercial Organic and Cyanobacterial Fertilizers on Instantaneous Water Use Efficiency in Drip Irrigated Organic Sweet CornWater and fertilizers are applied to maintain crop growth, yield, and quality. Nitrogen (N) fertilizer plays a crucial role in crop growth and yield development of sweet corn (Zea mays). Organic growers often use commercial organic animal- based fertilizers which vary in nutrient composition, forms of available N (NH4+- N and NO3--N), and have high transportation costs. Alternatively, cyanobacteria can be grown on-site as a source of N. Cyanobacteria haves unique dual properties because they... J. G. Davis, A. Sukor, C. Ramsey |
3. Optimizing Nitrogen Fertilizer Rates for Annual Cereal Forage ProductionNitrogen fertilizer provides one of the greatest returns on investment but also one of the highest operating expenses for annual cereal forage production. It is important to know the total nitrogen required by a crop to optimize yield and quality and to minimize nitrogen losses to the environment. It is also possible that annual cereal forage species and cultivars will have varying responses to nitrogen availability. The objective of this study was to determine the optimal nitrogen fertilizer... J. Spackman, R. Findlay, J. Sagers, J. Pandey |
4. Micronutrient Management to Optimize Yellow, Brown and Oriental Mustard Production in Southern IdahoOilseed crops hold a significant position in global agriculture, serving as vital sources of essential oils and as raw materials for numerous industries. Among these, yellow, brown, and oriental mustard are prominent for their multifaceted uses, particularly in the culinary and industrial sectors. However, these mustard varieties face challenges in achieving their maximum yield potential, largely due to suboptimal nutrient management practices. Fertilizer programs, though essential for productivity,... H. Ali, J. Spackman, J. Pandey |
