A study was made in 1967 and 1968 on a Nunn clay loam soil to determine the effects of row spacing on evapotranspiration (ET) and yields of corn ( Zea mays L.) in a semiarid environment. Double rows 0.3 m apart flanked on each side by spaces 1.8 m wide as used in the microwatershed system were compared with single rows in spacings of 0.9, 1.2, and 1.8 m. ET and yields of the double rows and the single rows of 0.9 and 1.2 m spacings were very similar. These results indicate an important degree of freedom is allowed in planning management systems such as microwatersheds to increase water use efficiency.
