Abstract: A field experiment was conducted during two consecutive Rabi seasons of 2015-16, 2016-17 at SIF farm of CSA University of Agriculture and technology, Kanpur on sandy loam soil with a view to find out the suitable organic sources and response of field pea to DAP. For this purpose, two doses of DAP (@100kg ha^-1, 150kg ha^-1) and organic sources (viz, control, Rhizobium inoculation, FYM@10t ha^-1, Vermicompost@2t ha^-1, FYM 10t ha^-1 + Rhizobium inoculation and Vermicompost+ rhizobium inoculation) were tried in randomized block design and replicated thrice. The important observations like growth parameters, yield attributes, yield, protein content in seed and economics were recorded. Result showed that application of DAP@150kg ha^-1 improved the growth and yield attributes and yield of dwarf pea significantly. It gave 27.81 q ha^-1 seed yield which was 2.29 q ha^-1 or 8.97% higher than the 100kg DAP ha^-1. All the organic sources proved to be over untreated plot in respect to growth, yield attributes and yield of dwarf pea. Application of vermicompost 2 t ha^-1 + Rhizobium inoculation proved to be best as it gave highest grain yield (32.65q ha^-1) and economic return (Rs.52487 ha^-1) followed by FYM @10t ha^-1 + Rhizobium inoculation (30.19q ha^-1) grain yield and Rs.47948 ha^-1 net profit.
