Effect of organic and inorganic sources of nutrients on rainfed wheat (Triticum aestivum)

Field experiment conducted during winter (rabi) season of 1991-92, 1992-93 and 1993-94, to study the effect of different revels of organic (FYM) and inorganic (N, P and K) sources of nutrient on rainfed wheat (Triticum aestivum L.), revealed that application of 10 t FYM/ha yielded significantly higher grain and straw yields of wheat over 5 t/ha and control (no FYM). Application of inorganic fertilizer @ 80 N + 60 P2O5 kg/ha being at par with 60 N + 30 P2O5 + 30 K2O kg/ha during 1991-92 and 1993-94 recorded significantly higher grain yield than this treatment during 1992-93 and rest of fertility levels. Incorporation of FYM and application of N, P and K also exhibited significant effect on uptake of NPK by grain and straw. FYM @ 10 t/ha with 60 N + 30 P2O5 + 30 K2O kg/ha was found optimum level to get the maximum yield in rainfed wheat under low/valley situation of UP hills.
