Field experiments were conducted at the University of Arizona Experiment Farm at Marana, Arizona, in 1970, to determine the effects of four plant populations on yield and agronomic characteristics of the cotton (Gossypium hirsutum L.) cultivar "Deltapine 16" and the grain sorghum[Sorghum bicolor (Linn.) Moench] hybrid "DeKalb A25". Significant differences in seed cotton yield due to plant populations were found. Boll size, lint percent, lint index, seed index, seed per boll, fiber length (upper half mean), fiber strength, fiber fineness, and plant height were not significantly affected by plant population. The efficiency of mechanical harvesting increased with plant population. No significant differences were found in grain sorghum yield due to the plant populations used in this test. Plant height, heads per plot, and seed index increased with plant populations, but head weight, yield per plants, heads per plant, and seed moisture content decreased. Plant population did not affect trash percentage with the combine used in this experiment. |
