Nitrogen Fertilization of Four Cotton Cultivars Grown on a Clay Soil

H.J. Mascagni, Jr., J.S. McConnell, and R.L. Maples


The Arkansas nitrogen (N) management system for cotton (Gossypium hirsutum L.) is designed to provide enough early-season N for normal yields monitor the plant during fruiting and maturation and when needed, apply supplemental N to accommodate above-average yield potentials. In order to balance inputs with yield capability, it is necessary to know how well each cultivar can respond to N inputs and its tolerance to higher-than-average rates of N. This study is designed to 1) measure yield responses of several cotton cultivars to varying rates of N fertilizer and 2) develop soil and plant diagnostic criteria to improve the accuracy of N fertilizer recommendations.
