Combination Air Seeder/Cultivator/Sprayer for Interseeded Small Grain/Cotton Cropping System

W.M. Lyle


Small grain-cotton rotation systems have proven successful in combating wind and water erosion, minimizing wind damage to cotton, and increasing cotton yields on the Texas Southern High Plains. The system with greatest producer appeal has been a terminated wheat or rye-cotton system since cotton can be harvested every year. However, insufficient stubble and residue often occur due to lateness in small grain establishment if sown after cotton harvest. A combination tillage tool has been designed to sow a small grain into growing cotton at the last cultivation or even later with minimal crop damage due to quick raising shanks and sweeps. Spring weed control and/or small grain termination can be accomplishment with a quick attaching hooded sprayer. The implement also allows simultaneous small grain and furrow dike establishment without degradation of the dikes. Successful stands of spring wheat, winter wheat and rye have been established on silty clay loam and fine sand loam soils in both diked furrows and undiked tractor and gage wheel rows.
