1. Barley Yield and Protein Response to Nitrogen and Sulfur Rates and Application Timing

The 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

2. Nitrogen Fertilizer Rate and Timing Implications for Malt, Food, and Feed Barley Production in Southern Idaho

Nitrogen 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.

3. Malt Barley Yield and Quality Response to Nitrogen and Sulfur Fertility

Nitrogen (N) and sulfur (S) and are critical nutrients for producing high-quality malt barley but can be difficult to manage in semi-arid production systems where rainfall and, periodically, irrigation is variable. High spring precipitation or excessive irrigation events can favor N and S leaching reducing yield and grain quality. However, N fertilizer additives such as urease inhibitors, nitrification inhibitors, and controlled-release products may improve N availability. Irrigated... J. Spackman, J. Spackman, J. Hatch, J.

4. Liming for Improved Nutrient Utilization and Weed Management in Wheat

Soil acidification is an increasing concern for agricultural productivity in Eastern Idaho, where low soil pH threatens the yield and quality of key crops such as barley and spring wheat. Acidification occurs from the long-term application of ammonium-based fertilizers and other management practices, leading to aluminum toxicity and nutrient imbalances that inhibit root development and reduce yields. Farmers in the region are exploring strategies to address this challenge, including the use of... T. Jacobsen, J. Spackman, A. Adjesiwor, J. Sagers, K. Schroeder, J. Bevan, K. Mookodi, J. Gibbons
