ABSTRACT
Cultivar yields as influenced by inter row competition were measured on five cotton cultivars at Stoneville for a two year period (1982 and 1983). The objective of this study was to determine the feasibility of breeding cotton for skip-row production systems. Cultivars were planted in a 4 x 4 skip-row pattern and yield comparisons were made on inside versus outside rows. The F values for the year x cultivar, cultivar x pattern (inside vs. outside), and cultivar x pattern x year were nonsignificant being 0.90, 0.71, and 0.44, respectively. Only the pattern x year interaction was significant. This interaction was probably due to the amount and distribution of rainfall. These data indicate that it would not be feasible to initiate a breeding program to develop cultivars for skip-row production systems.
