Evaluation of Date of Planting and Irrigation Termination on the Yield of Upland and Pima Cotton, 1992

Six field experiments were conducted at three locations in 1992 in Arizona to evaluate the response of Upland and Pima cotton to dates of planting and dates of irrigation termination. Planting dates ranged from as early as 11 March in the Yuma Valley (150 ft. elevation) to 30 April at Marana (2,000 ft. elevation). Dates of irrigation termination ranged from 15 July in the Yuma Valley to 18 September at Maricopa. Planting date was commonly a significant effect in these experiments, particularly with Pima cotton. Irrigation termination results over three locations and four seasons show increases of approximately 60 to 120 lbs. lint /acre by extending later irrigations.
