Abstract
Nitrogen (N) is an essential nutrient for cotton (Gossypium hirsutum L.) production. A standard fertilization practice for N in the Mid-South is a split application. However, a single N application at planting would potentially save fuel and labor cost. The objective of this study was to determine the effectiveness of controlled release nitrogen (CRN) fertilizers applied to various soils relative to pre-plant and split application nitrogen fertilizer programs for cotton production. The study was conducted in 2010 and 2011 on a Bosket fine sandy loam, a Tiptonville silt loam soil, and a Sharkey clay soils. At each location, ten treatments of 134 kg N ha-1 were applied with granular CRN, liquid CRN, UAN, urea and several combinations of CRN blended with traditional N fertilizers. On clay soils, the granular ESN and urea had significant yield increases over the liquid Nfusion and UAN treatments. No significant differences in lint yield were found from any nitrogen treatments on silt loam and sandy loam soil. Significant fiber quality X N rate interactions were evident on all soil types.
