Abstract
In field trials on Travis fine sandy loam in Texas in 1972 and '74, grain sorghum cv. Oro was sown on 14 April in double rows 25 cm apart in lysimeters of the percolative type and harvested on 25 July. In 1972, trickle and sprinkler irrigation systems were compared, both treatments being irrigated 3 times/week at rates of 1.1 times the measured soil water losses. In 1974, trickle irrigation frequencies of 3, 2 and 1 times/week were compared, the same total amount of water/week being applied in each treatment. No significant difference in grain yield or water-use efficiency was found between the trickle and sprinkler irrigation systems with 3 irrigations/week, yields in 1972 being 9.2 and 10.2 t/ha, resp. Variation of trickle irrigation frequency also had no significant effect on yield or water-use efficiency, yields in 1974 being 10.7, 11.0 and 11.3 t/ha for 1, 2 and 3 irrigations/week, resp.ADDITIONAL ABSTRACT:Crop response and water use efficiency (ratio of grain yield to total crop water use) of grain sorghum in an enviromentally controlled lysimeter installation were investigated using trickle and sprinkler irrigation. Also, effects of different trickle irrigation frequencies on the crop growth and grain yield were studied. Results indicate no significant differences in yield or water use efficiency when using trickle and sprinkler irrigation with three irrigations per week. Also trickle irrigation frequencies of 1, 2, and 3 irrigations per week appeared to have no significant effect on yield or water use efficiency of grain sorghum on a layered sandy loam soil
