Abstract
Field studies were conducted on a Greenville fine sandy loam to determine the effects of soil moisture regime and N rate on recovery of applied N by cotton. In general, irrigation decreased the percentage of N in plants but tended to increase total N uptake as a result of the increase in dry matter production. Applied N increased both the N percentage and total N uptake of plants, either with or without irrigation.The slopes of the linear regression equations for nitrogen recovery on nitrogen applied for irrigated cotton were about twice as large as those for unirrigated cotton.Five years data for both irrigated and unirrigated cotton closely fits the regression equation log Y = 2.333 + 0.727 log X, where Y = dry matter yield and X — N uptake.Keywords
