Abstract: Pulses occupy unique place in Indian diet with supplying of vegetable protein to primarily starchy diet and provide an essential supplement for balance diet. Therefore, it is essential to increase the sustainable productivity with more appropriate management of nutrient utilization of plants so that with same area, we can increase pulses sustainable production. In future sustainable pulse production will greatly depend on soil health because of heavy doses of chemical fertilizers, extensive removal of phosphorus by the crops under intensive cultivation and degraded soil condition day by day will be chief in concern for decreasing sustainability in production and environment. In this regard, a field experiment was conducted at Instructional Farm Rajasthan College of Agriculture, Udaipur with four levels of phosphorus (0, 20, 40 and 60 kg P2O5/ha) in greengram. Results workout in quadratic equation with four levels of phosphorus found that 48.62 kg P2O5/ha is proved to be the best dose for optimum input responsive yield (1384.85 kg/ha.).
