Abstract:
Short staple variety trials have been conducted for three years on the demonstration farm, at the Maricopa Agricultural Center. Twenty varieties, received from various seed companies, were entered into the test in 1989, 19 varieties in 1990, and 10 varieties in 1991. Yields ranged from 3353 to 4679 lbs. seedcotton/acre in 1989, 829 to 1428 lbs. lint/acre in 1990 and 1099 to 1246 lbs. lint/acre in 1991. Results form the statistical analysis showed significant differences among varieties for all three years. Differences among varieties in 1989 showed no clear trends with respect to maturity types. In 1990, those varieties that were medium to early season maturity types yielded higher than full season maturity types. The results in 1991 showed medium maturity types yielding in the highest ranking of the test without exception, while the performance of the full season maturity types was mixed. An additional test with narrow row spacing (30 inches) was included in 1991 with 5 varieties. Yields ranged from 947 to 1117 lbs. lint/acre. No significant differences were detected among varieties.
