India has virtual monopoly in pigeonpea production accounting to 90% of world’s total production but the average productivity is relatively low due to terminal moisture stress and the production is not adequate to meet the demand of increasing population. To meet the said demand pigeon pea productivity has to be increased. There is a need for judicious management of available water and plant nutrients through different fertilizers to increase the productivity and to reduce the production costs of pigeonpea. Application of fertilizer at appropriate stages of crop growth ensures a regular flow of both water and nutrients resulting in increased growth rates and higher yields. Drip fertigation method is an option for efficient use of water and nutrients through improvement in crop yield per unit volume of water and nutrients used. Fertilizer use efficiency up to 95% can be achieved through drip fertigation. In the present paper, as reported by different research workers throughout world drip fertigation in pigeon pea saves 30% to 70% of water, significant fertilizer savings of 20-60% increases yield by 20% to 90% and results in higher water use efficiency from 35.5% to 50.8 % as compared with conventional method resulting in reduction of cost of cultivation.
