Abstract

The effect of soil physical properties such as bulk density, soil moisture content, soil temperature and water use efficiency on groundnut production under drip irrigation with black plastic mulch was investigated by four treatments namely drip-T1, drip with mulch-T2, mulch-T3 and control T4. The obtained results of the bulk density are within permissible limits of 1.3 to 1.6 g cm-3 for sandy soil. Compared to all treatments, the drip with mulch treatment reported optimum soil moisture content and s oil temperature. The obtained results of water use efficiency for drip with mulch, drip, mulch, and control were 12.44,9.73, 8.05 and 6.45 kg ha-1 mm-1 duly. The higher water use efficiency under drip with mulch treatment was reported because of efficient use of application of irrigation water by adopting drip
