Effect of Different Rates and Time of Application of Phosphorus on Yield, Soil Fertility, Nutrient Uptake and Monetary Returns of No-till Maize (Zea mays L.) after Lowland Rice

Field experiment was conducted during dry seasons for 2 consecutive years at College of Agriculture, Rajendranagar, Hyderabad on no-till maize after lowland kharif rice sandy clay loam soil. The laid out in randomized block design with factorial concept and replicated thrice. Treatments executed are three Phosphorus levels (30, 45 60 kg P2O5 ha-1) application times (at 10 days before harvest rice, the time sowing first irrigation to maize). results revealed that ha-1 recorded superior grain stover yield, gross returns, net benefit cost ratio nutrient uptake (Nitrogen, Potassium) crop over 30 ha-1. But, left behind soil lower amount available Nitrogen Potassium higher status crop. Application phosphorus being par resulted better yield maize, its delayed or depleted greater from than along irrigation.
