Abstract:
Investigation was taken up to assess the combined effects of drip irrigation and mulches on yield, water-use efficiency and eco­nomic return of cucumber. The treatments of the study comprised of different combinations of three drip irrigation levels (100, 80 and 60% of crop water requirement, ETc) and three mulches (white polyethylene sheet, black polyethylene sheet and no mulch). The yield of cucumber increased with the increasing amount of irrigation water in mulched treatment. The yield per plot was 71.93 kg, yield per 1000 square meter 11.07 t and yield per ha 110.70 t ha^-1 under treatment consisting of 100% crop ET with white plastic mulch as compared to black mulch and without mulch. The average water use efficiency was highest in treatment consisting of drip irrigation at 60% crop ET with white plastic mulch (9.70 t ha^-1cm^-1).
