Nutrient availability in bt. cotton under drip fertigation

Cotton occupies sizeable area in India including Maharashtra which is progressively increasing with creation of irrigation amenities. Farmers adopting furrow irrigation causes percolation, nutrient leaching and volatilization at one end and unproductive loss of ground or surface water on the other end. Therefore, experiments were conducted during Kharif season of 2015-2016 to evaluate nutrient availability in Bt cotton by using drip fertigation under different phosphorous sources.
