Effect of Different Phosphorus Level on Nutrient Content, Uptake and Economics of Urdbean under Custard Apple based Agri-Horti System

An experiment was carried out in kharif season of 2009 to investigate the effect of phosphorus on nutrient content, nutrient uptake and economics of urdbean under custard apple based agri-horti system. The treatments tested were six levels of phosphorus (0, 15, 30, 45, 60 and 75 kg P2O5/ha) in a randomized block design. Total nutrient uptake/ha was significantly highest with phosphorus application up to 75 kg/ha while cost of cultivation, gross return, net return and B:C ratio were also found maximum with same level of phosphorus application
