Reduced tillage can conserve soil, increase moisture in the soil profile and in some instances enhance crop yields. Conservation tillage can lower production costs because it requires fewer trips over the field. A six-year study was conducted to evaluate cotton lint yield response to different tillage systems and nitrogen fertilization rates. Results showed tillage practices had a direct effect on lint yields while nitrogen fertilizer rates affected yields only in certain years. Lint yields varied during the six year period from a high of 1047 pounds of lint to a low of 232 pounds largely due to wide variation in precipitation. Rainfall during the growing season varied from 4.72 inches in 1996 to 23.53 inches in 1992.
