Yield sustainability and chemical fertilizer economy through IPNS in capsicum (Capsicum AnnumL. Var.grossum) under dry temperate condition of Himachal Pradesh

A field experiment to evaluate the effect of five organic sources of plant nutrients and three fertility levels on productivity and economics of tomato was conducted during Kharif seasons of 2006 and 2007 under dry temperate region of HAREC, Kukumseri (L&S), Himachal Pradesh. Among organic sources, application of FYM @ 5 t/ha has recorded the higher values for all yield attributes except No. of branches/plant and was followed by FYM @ 2.5 t/ha + Azotobacter. However both these treatments were significantly at par with each other in recording significantly more No. of branches/plant, higher yield and productivity. Significantly higher economic efficiency of Rs. 1567.6 was achieved with the application of FYM @ 2.5 t/ha + Azotobacter and was followed by FYM @ 5 t/ha (1567.6 Rs./ha/day). Increase in the level of NPK has significant influence on yield, productivity and economic efficiency. Significantly higher values of different yield attributes were recorded with the application of 150% NPK which was reflected in getting significantly higher capsicum yield (190.0 q/ha) and productivity (1.04 q/ha/day) with greater economic efficiency of 1766.7 Rs./ha/day.
