The effects of okra leaf shape on boll rot, yield, and other important characters of Upland cotton (Gossypium hirsutum L.), were investigated at three locations in Louisiana and on three varietal backgrounds. Varieties responded in a similar manner to the leaf shape treatments for all characters studied, but the location ✕ leaf shape interaction was significant in some cases.The okra leaf shape character, as an average of varieties and locations, caused a significant reduction in the incidence of boll rot in comparison with normal leaf cotton. It was associated with a significant increase in yield, earliness, lint percentage and micronaire value, and a substantial increase in fruiting rate. Okra leaf shape had no effect on boll weight, fiber length, fiber length uniformity, or fiber strength, but caused a reduction in fiber elongation and total leaf area.A mixed population of okra leaf and normal leaf plants in a 1:1 ratio was investigated. The mixed population was found to have no advantage over the pure populations of the contrasting leaf shapes.
The effects of the super okra leaf shape on boll rot. yield, plant and fiber characters of Upland cotton, Gossypium hirsutum L., were investigated at three locations in Louisiana. Near isogenic populations of super okra leaf and normal leaf on each of three varietal backgrounds were used.Super okra leaf shape, as an average of varieties and locations, caused a significant reduction in boll rot, yield, fiber length, and total leaf surface area in comparison with normal leaf cotton. Super okra leaf shape caused an increase in earliness, lint percentage, fruiting rate, and micronaire value, but had no effects or inconsistent effects on boll size, fiber length uniformity, fiber strength, and fiber elongation. The interactions of variety ✕ leaf shape and location ✕ leaf shape were significant for some of the characters studied.A mixed population of super okra leaf and normal leaf plants in a 1:1 ratio was investigated. The mixed leaf population was found to have no advantage over the pure populations of the contrasting leaf shapes.
Deep placement of fertilizer and deep tillage were evaluated as to their effect on crop yields and root development. Experiments conducted for several years on four soil types showed that greater root development in the subsoil and increases in yield may be expected from deep fertilizer placement and deep tillage on soils that possess traffic pans. This was particularly evident in years of below average rainfall, when the increased root development in the subsoil caused by deep placement of fertilizer or deep tillage enabled the crop to better withstand dry periods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
