1. Effect of Foliar Zinc Application on Durum and Spring Wheat Grain Yield and QualityZinc (Zn) deficiency represents a common micronutrient deficiency in human populations, especially in regions of the world where staple food crops are the main source of daily calorie intake. Micronutrients like Zn also plays an important role in growth and development of plant thereby affecting crop yield and quality. A two-year field trial was conducted at Sidney, Montana, to investigate the effect of foliar application of Zn on yield and grain quality of spring wheat. Zinc treatment included... F. Etemadi, R.

2. Nitrogen Management in Semi-arid Conservation Cotton Production SystemsThe Southern High Plains (SHP) region of Texas is one of the largest cotton-producing regions in the United States. Cotton production is hindered by climatic conditions and wind erosion, but attempts have been made to adopt conservation management practices like cover crops and crop rotations to limit these effects. Conservation management practices can reduce a soil’s susceptibility to wind erosion, but their adoption has been limited on the SHP due to producers’ concerns regarding... J. Burke, K. Lewis, W. Keeling, W. Keeling |
3. Cover Crop Function and Management Optimization for Semiarid West Texas Cropping SystemsWater-use is a primary concern preventing integration of cover crops in dry climates. Recent research has demonstrated that adequate cover crop residue (with optimal termination timing) is more likely to improve soil water dynamics for the subsequent crop. Regarding cover crop function in West Texas, wheat stubbles as a fallow may offer a cheap and effective solution to prevent wind erosion and facilitate water storage in soil profile. Optimum management practices are likely different though... T. Hussain, R. Noland, R. Matschek, . Delaune, E. Kimura , J. Muir |
4. Evaluating the Profitability of Nitrogen Management Strategies to Increase Yield in Regenerative Cotton Production SystemsSoil health management practices, such as cover crops and no-till systems, are common in semi-arid cropping systems to reduce wind erosion. However, implementing these practices can also lower cotton yield. As a result, cotton production using no-till and cover crop systems in semi-arid environments tends to be less profitable than conventional systems, despite lower costs from fewer tillage operations during the growing season. For these soil health practices to be economically sustainable in... A. Wright, J. Burke, K. Lewis, W. Keeling, W. Keeling |
