      DPL 41 and Pima S-5 cotton were planted at low, medium, and high planting rates on April 12, April 27, and May 10 on the Safford Experimental Farm in 1983. Heavy rains in late September and early October reduced lint yields. Pima S-5 produced 66% as much lint as DPL 41. Both varieties had the highest lint yield when planted on April 27. The highest planting rate produced the highest yield for DPL 41, while the medium planting rate produced the most lint for Pima S-5 on April 27.

      Several upland cotton varieties and one Pima cotton variety were planted and watered up after Poco barley and Yecora Rojo wheat on the Safford Experimental Farm in 1983. Three upland varieties were planted and watered up on July 2. McNair 235 produced the most lint for all three late planting dates. Pima cotton produced the lowest yields. Single cropped DPL 90 produced $8.47 more income/acre than McNair 235, following Poco barley. However, double cropped cotton and barley produced $57.96 more/acre than single cropped cotton, followed by single cropped wheat.
