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.
