As new and morphologically different wheat cultivars are developed, altered cultural practices may be required to obtain optimum performance from a particular cultivar. This study compared the relative responses of three contrasting hard red winter wheat cultivars ( Triticum aestivum L. em Thell.) under four planting arrangements. Cultivars studied were ‘Triumph 64,’ ‘Sturdy,’ and ‘Parker.’ A split plot experimental design was employed with cultivars as main plots and planting arrangements (two row spacings and two drilling patterns) as subplots. Characters investigated were grain yield, tillers/unit area, kernels/spike, kernel weight, test weight, plant height, maturity, and protein content of the grain. The cultivars differed significantly for all characters except grain yield. Tiller count was significantly affected by row spacings and drilling patterns while kernels per spike was significantly influenced by row spacings. Planting arrangements did not induce significant responses in any of the remaining characters. A significant cultivar by spacing interaction was noted for test weight and a significant cultivar by drilling interaction was noted for plant height. The results of this experiment indicate that planting arrangements may influence yield components and other characters in the wheat cultivars studied. However, the optimum planting arrangement for increased yield could not be determined.
