Abstract
In a 3-yr field study, a short-season cotton production system was compared with the traditional long-season system. Average cotton lint yields of 3 short-season cultivars were 826 kg/ha as compared with 670 kg/ha for the long-season grower check fields. Four fewer insecticide applications and one less irrigation were required on the short-season test plots as compared with the check long-season fields. Production costs were lower for the short-season system as compared with the Lower Rio Grande Valley (LRGV) of South Texas conventional long-season system. In 1978, the production cost advantage of the short-season production as compared with the conventional was $dollar;0.39/kg of lint produced. A shift to an integrated short-season production system in the LRGV has both economical and environmental advantages over the conventional, long-season system.
