ABSTRACT

Irrigated pigeonpea is a cash crop growing in rabi season in the South Gujarat to overcome the water logging problem occurred during kharif Season. Ascending irrigation levels progressively increased the grain yield without altering the harvest index but the significant increase occurred upto 0.30 IW/CPE ratio. The percentage increase in grain yield over control was 128.45 and 135.88 under 0.30 and 0.60 IW/CPE ratio, respectively. The consumptive use (CU) of water increased with increasing irrigation levels, reaching as high as 323.50 mm under 0.60 IW/CPE ratio. Water use efficiency (WUE), on the other hand decreased with ascending irrigation regimes but more sharply beyond 0.30 IW/CPE ratio.
