Drip Fertigation for Green Peas

The research trial was conducted to determine the best irrigation and fertigation scheduling through drip irrigation in a saline soil to optimize green pea yield, field water use efficiency and fertilizer use efficiency. The experiment was laid out in split plot design with four main treatments, four sub-treatments and three replications. The irrigation levels comprised based on crop evapotranspiration (ETc) viz., I1: 100% ETc, I2: 85% ETc, I3: 70% ETc and I4: 55% ETc. The irrigation water was applied at an alternate day under drip irrigation as per the treatments. The Fertigation levels (water soluble fertilizers) viz., F1: 125% RD, F2: 100% RD, F3: 75% RD and F4: 50% RD through drip irrigation. The results showed that the irrigation level I3 (70 % ETC) obtained maximum yield (34.47 q/ha) as compared to the other levels of irrigation and the fertigation level F3 (75 % of RD) obtained maximum yield (30.24 q/ha) as compared to the other levels of fertigation.
