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. Evaluating the Trade-offs of Cover Crops in Dryland Wheat Systems of the Colorado PlateauOn the semi-arid Colorado Plateau, dryland farmers are challenged by severely degraded soils and low and increasingly unreliable precipitation. Cover crops have been shown to improve soil fertility and mitigate soil erosion in many regions, but are also associated with use of limited soil moisture, a cost that could mean decreased cash crop productivity for farmers. Most literature on cover crops comes from relatively humid climates, where crop yield penalties due to cover crops may be less pronounced.... L. Eash, A. Berrada, K. Russell, S. Fonte |
3. Evaluation of Starter Nitrogen Fertilizer Rates for Grain Sorghum Production in the Southern Great PlainsNitrogen (N) is the most essential nutrient for plant growth and is often the most limiting in crop production. Timely applications of N throughout the growing season are critical to maximizing crop yield. Applying N at planting has proven to be an effective practice, giving plants accessible N early on to increase vegetative growth. Although this is commonly practiced in corn production throughout the Oklahoma and Kansas area, little research has been conducted concerning proper N starter rates... M. Thomas, B. Arnall |
