Abstract:
A single field study was established during the 2002 growing season to evaluate the effects of planting date (PD) on the yield and fiber quality characteristics of several cotton varieties commonly grown in the Upper Gila River Valley of Safford. Seven varieties were chosen for evaluation in 2002 ranging from early to medium-full varieties. These seven varieties were planted on three separate planting dates (2 April, 15 April, and 3 May) in a split-plot within a randomized complete block design with four replications. Overall analysis of variance revealed significant differences due to PD (OSL=0.0291) but no significant differences among varieties (OSL=0.5164) or in the interaction between PD and variety (OSL=0.4052). Four of the varieties evaluated produced the highest yield with the later PD (3 May). The remaining three varieties performed best with the 2nd PD (15 April).
