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. Changes in Soil Quality During the Transition from Irrigated to Dryland Cropping SystemsThe availability of irrigation water enhances crop productivity and, in turn, increases crop residue inputs and soil quality. With increased pressure on declining groundwater resources, some formerly irrigated lands are being transitioned to dryland management. However, little is known about the shifts in soil quality after conversion from irrigated to dryland cropping systems. The objective of this work was to quantify the effect of irrigation retirement on the early changes in soil quality.... A. Nunez, R. Ball, M. Schipanski |
3. Evaluation of Soil Test Phosphorus Extractants and Tissue Analysis for Corn in KansasPhosphorus (P) is a critical nutrient for corn (Zea mays L.) productivity. Determining an appropriate concentration of soil test phosphorus (STP) and P tissue concentrations is a fundamental step needed to make accurate phosphorus management decisions. The main objective of this study was to evaluate the relationship of four different STP methods (Mehlich 3, Bray 1, Bray 2, and H3A) for corn production and determine critical P tissue concentration at different growing stages. The study... G. Roa, D. Ruiz diaz |
4. Exploring Long-Term Phosphorus Management Strategies for Optimizing Crops Yields in KansasPhosphorus (P) is a crucial nutrient for sustaining crop productivity, yet its scarcity often challenges agricultural endeavors. Recognizing the essential role of P fertilization in maintaining agricultural productivity, this study takes a multi-year approach to P management. It specifically delves into the intricate dynamics of long-term P placement, evaluating its impact on crop yield under varying rates and combinations. The primary objective is to discern the most effective phosphorus fertilization... D. Ruiz diaz, G. Roa |
