1. Predicting Crop Yield Losses Due to Soil-water Salinity: Comparison of Traditional and Alternative ApproachesIt is estimated that 2,000 ha of cropland are taken out of production daily worldwide due to salinization and sodification. Salinity is estimated to result in economic losses of $27.3 billion U.S. dollars annually. Our project aims to jointly develop techniques for quantifying the severity of soil-water salinity and impacts on crop production on surface-irrigated fields in Pakistan’s Indus River Valley and the Lower Arkansas River Valley (LARV) in Colorado. The Fairmont Drainage District... A. Brown, A. Andales, T. Gates |
2. Influence of Irrigation Timing and Amount on Cotton Physiology and Nutrient PartitioningThis study explores the impact of varying water levels on nutrient uptake in cotton plants, known for its sensitivity to environmental conditions. Recognizing the pivotal role of water availability in agricultural productivity, the experiment employed different irrigation scenarios and assessed the efficiency of nutrient absorption in cotton under these varied circumstances. The research also focused on analyzing nutrient content in different plant tissues,... K. Vargas, K. Lewis, J. Bicaldo, J. Burke |
3. Evaluation of the Nutrient Requirements and Uptake Indices of Ten Modern Cotton CultivarsThis study aims to re-evaluate the partitioning patterns and nutrient uptake index of new and soon-to-be released cotton cultivars to optimize the nutrient inputs for farmers and producers. The study will be divided into two phases: Phase I will be the determination of different nutrient uptake indices of 10 modern cotton cultivars and Phase II will be the development and establishment of new fertilizer management strategies for modern cotton cultivars using the results of plant nutrient uptake...
