Popis:	Data from a pest management program on cotton in dryland and irrigated conditions was used to develop an economic evaluation of insect control in the Lower Rio Grande Valley of Texas during 1973-75. A strong economic advantage was shown for dryland production. Dryland cotton had 89% of its harvested bolls set by June 19 while irrigated cotton had 88% set by July 17; thus, irrigation delayed maturity. Dryland cotton required 5.5 kg/ha (4.91 lb/acre) less insecticide AI than irrigated cotton. Lint yields for dryland cotton were 541 kg/ha (483 lb/acre) vs. 615 kg/ha (549 lb/acre) for irrigated cotton and were equal by statistical analysis. However, production costs for dryland cotton were $266.88/ha ($108.05/acre) less than irrigated cotton and dryland cotton returned net profits of $142.99/ha ($57.89/acre) above those of irrigated cotton.
