Abstract
Effects of crop geometry on the evapotranspiration (ET) of water were studied over two growing seasons at the Caddo Research Station, Ft. Cobb, Oklahoma. Peanuts were grown in 12-inch rows and 36-inch rows. Plots were oriented with rows north-south and east-west. The four combinations of these treatments were replicated three times each year. A water budget on accrued water was computed each year. Difference of water content between dates was sensed with a neutron probe. These differences were corrected for either drainage or accretion from below by the deduction of a computed integrated water flux. This flux was determined from tensiometric measurement of total hydraulic head and pressure head across the fifth foot of the profile. (Author)
