摘要

Field experiments were undertaken on sandy soils with three cropping systems at Giridih,Jharkhand,India for two years during 2012-2014.The experiments were executed in split plot design by assigning water soluble phosphorus(WSP)fertilizers in main-plot and recommended dose of phosphorus(RDP)in sub-plot with three replications.The maximum economical yield of rice(4705 kg/ha),baby corn(842 kg/ha)and Chickpea(920 kg/ha)were recorded with the application of 30%WSP.The maximum economical yield of successive crops-wheat(3185 kg/ha),mustard(1720 kg/ha)and groundnut(1578 kg/ha)were recorded with the application of 30%WSP and 100%RDP treatment.Almost similar trends were noticed in terms of by-product yield,nutrient uptake and residual soil fertility status.All the levels of WSP(30%-89%)in complex fertilizers were found to be equally effective for grain yield,straw yield,nutrient uptake,and residual soil fertility.
