1. Biofuel Byproducts As Nitrogen Sources for CropsThe new development of ethanol and biodiesel plants in the United States is creating a large, and potentially excessive, quantity of byproducts in the forms of distillers grains and oilseed meals. The organic nitrogen (N) compounds in these byproducts rapidly mineralize in soils, showing the potential to be used as a N fertilizer source to plants. The objective of this research is to evaluate the application of biofuel byproducts on yield, size distribution, and nutrient uptake for Russet Umatilla... A. Moore, A. Alva, H. Collins, R.

2. Barley Yield and Protein Response to Nitrogen and Sulfur Rates and Application TimingThe introduction of new barley varieties, as well as changes in management practices, necessitate a re-evaluation of nitrogen (N) and sulfur (S) nutrient management guidelines. Nitrogen has a significant impact on barley grain quality and yield. Overapplication of N can result in lodging, groundwater pollution, and high protein content, resulting in lower end-use quality of barley, while underapplication of N results in reduced grain quality and yield. Sulfur promotes N utilization in barley plant... O. Adeyemi, J. Spackman, J. Sagers, J. Marshall, Z. Hong, R. Findlay, J. Bevan |
3. Nitrogen Fertilizer Rate and Timing Implications for Malt, Food, and Feed Barley Production in Southern IdahoNitrogen is an essential nutrient required to produce high-yielding barley. Nitrogen strongly impacts barley yield, grain protein, tillering, and lodging potential. Unlike other crops such as corn, available nitrogen must be carefully managed for producers to achieve both optimal yield and grain quality for malt, food, and feed barley. Exessive nitrogen availability increases grain protein concentration that may be unsuitable for malting but may be ideal for feed or food barley. The objective... J. Spackman, O. Walsh, A.
