Abstract:
A field experiment was conducted to evaluate the effect of planting date on Upland as a short staple (Gossypium hirsutum L.) and Pima cotton as a long staple (Gossypium barbadense L.) cotton. Planting dates were 27 April, 13 May, 27 May, and 9 June, 1988. Cotton varieties consisted of three maturity groups: early maturity Delta and Pine Land 20 (DPL 20) and full season Delta and Pine Land 90 (DPL 90) from G. hirsutum L., and Pima S-6, a variety of the more indeterminate type G. barbadense L. A number of cold periods at Marana in the early spring of 1988 created unfavorable conditions for all cotton varieties on the early planting date. This condition resulted in lower head unit (H.U.) availability during germination, and significantly altered the usual pattern for flowering on planting date (PD) 1. The amount of H.U. accumulation for PD 2, especially during germination, was higher than for PD 1. (Abstract shortened with permission of author.)
