Abstract:

A field experiment was conducted on sandy loam soils (Inceptisols) in Himachal Pradesh, India, to investigate the effect of different levels of drip irrigation with and without plastic mulch on the yield and irrigation water requirement of capsicum. The following treatments were employed: (T1) drip irrigation with V volume of water; (T2) drip irrigation with 0.8V volume of water; (T3) drip irrigation with 0.6V volume of water; (T4) surface irrigation; (T5) T1+ plastic mulch; (T6) T2+ plastic mulch; (T7) T3+ plastic mulch; and (T8) T4+ plastic mulch. Drip irrigation at 0.8V volume of water recorded a significantly higher yield (116.69 q/ha) compared with surface irrigation. Drip irrigation+polyethylene mulch increased crop yield (131.47 q/ha). Water use efficiency with sole drip irrigation, drip irrigation+polyethylene mulch and surface irrigation was 3.73, 3.88 and 2.35, respectively. Drip irrigation+polyethylene mulch besides the 55.6% water saving has also resulted to 37% higher yield compared with surface irrigation only. The benefit-cost ratio of capsicum cultivation under drip irrigation, drip irrigation+polyethylene mulch and surface irrigation was 2.66, 2.77 and 2.27, respectively.
