Abstract:
A series of studies were conducted around the southeastern region of the state during the 2002 cotton growing season to evaluate the effects of a twin-line (TL) planting configuration on fiber quality and lint yield. Two of the three studies were conducted on grower cooperator fields with large block comparisons or demonstrations of TL versus single-line (SL) configurations. Fiber quality was essentially the same for both demonstration locations. Yield differences were observed in both locations with the Graham County location experiencing a 130 lb lint yield decrease in the TL plots. The Cochise County location experienced a 328 lb lint yield increase in the TL plots. The third study was a split plot within a randomized complete block design with planting configuration (TL or SL) as the main effect and variety as the sub-unit effect. . No significant differences were detected in the main effect, sub effect or the interaction with respect to yield. Trends were observed however, indicating less difference between the TL and SL with respect to yield for varieties with a more columnar growth pattern. Fiber quality results indicated no significant differences among any of the treatments
