Minimum Seedbed Preparation for Cotton
1968
Phillips, R. E.
The effect of minimum seedbed preparation treatments on growth and yield of cotton grown on Sharkey clay and Dundee silt loam soil was investigated. Cotton was grown on Sharkey clay for a period of 5 years at one location and a period of 4 years at another location. Cotton was grown on Dundee silt loam for a period of 4 years at one location. Plant and soil measurements were made to evaluate the effect of seedbed preparation on growth and yield of cotton. Plant measurements which were conducted were: final stand count, soil water content of seedbed at time of planting, mature cotton plant height, total hoe-time, total seedcotton yield, and seedcotton yield at first harvest. Growth of cotton and seedcotton yield from treatments considered to be minimum seedbed preparation treatments on both Sharkey clay soil and Dundee silt loam soil were as high as from treatments considered to be current or innovations of current seedbed preparation systems provided heavy weed infestations did not exist. Seedcotton yields of spring prepared seedbeds were equal to fall prepared seedbeds for two direct comparisons on Sharkey clay soil. Date of maturity of cotton was not affected by differing degrees of seedbed preparation. Heavy infestations of late winter or early spring weeds must be killed on seedbeds receiving minimum preparation if adequate stands and no reduction in yields are to be obtained.
