1. A New Hydroponic System for Testing Mineral Nutrient Deficiencies and It's Application to SoybeansCorrelating plant tissue nutrient concentrations with visual symptoms is valuable in combating mineral nutrient deficiencies and toxicities. Due to changing climates and decreasing water supplies throughout the world, agricultural lands need to improve nutrient and water management in crops, including soybeans (Glycine max L.).Because nutrient concentrations can be easily controlled, hydroponics effectively demonstrate isolated specific nutrient related symptoms. However, many hydroponic... A.M. Lambert, S.M. Anderson, D.L. Cole, A. Haderlie, C.J. Seely, B.G. Hopkins |
2. Combined Nitrogen with Magnesium or Zinc Effects on Sugarbeet Yield Sucrose Concentration, and Nutrient Uptake Under Conventional and No-till SystemsSugar beet (Beta vulgaris L.) is an important cash crop in the Lower Yellowstone River valley. Fertility, especially nitrogen (N) fertilizer, management is critical for sugar beet yield and sucrose concentration. While farmers are switching from a conventional tillage method to a no-till system for sugar beet cultivation, nitrogen (N) fertilizer application timing might need to be adjusted. Furthermore, micronutrients may enhance sugar beet yield and sucrose concentration. A two-year... C. Chen, M. Etesami, M. Abdelhamid |
3. Genotypic Variation in Winter Wheat Yield Components Response to Nitrogen Management and Seeding DensityAchieving optimal winter wheat grain yield requires understanding genotypic variations in yield component formation under nitrogen (N) application timing and seeding density management strategies. This study evaluated whether modern winter wheat genotypes exhibit differential yield formation pathways under varying N timing and seeding rate conditions, and whether reducing N rates while increasing seeding density (or vice versa) could maintain yields while reducing input costs. Additionally, we... S. Abiola, A. Silva, S. Phillips, P.R. Abiola, B. Arnall |
