MAIZE AND WHEAT CROP PRODUCTION AS INFLUENCED BY BASIN AND FURROW-BED IRRIGATION METHODS

Water plays an important role in the agricultural production system of Pakistan. Judicious use of water through proper irrigation method; can increase its productivity. Basin and furrow-bed irrigation methods were evaluated for two consecutive years (1999—2001) under a maize-wheat cropping system. The mean maize grain yield was 39% higher under furrow-bed than basin, whereas, wheat grain yield was 8% less. On average, applied irrigation depths were around 30% less under furrow-bed than under the basin irrigation method. The mean water use efficiency (WUE) for maize and wheat as 63% and 17% higher under furrow-bed than basin irrigation method, respectively. The higher WUE under furrow-bed may be attributed to applied water saving and improved soil environments
