Effect of Integrated Nitrogen Management on Growth, Yield and Economics of Wheat (Triticum aestivum L.)

Abstract

The present investigation entitled “Effect of integrated nitrogen management on growth, yield and economics of wheat (Triticum aestivum L.)” was carried out during the rabi season of 2016–17 at the B.T.C.CARS (IGKV), Bilaspur (Chhattisgarh). The experiment was laid out in 3 times replicated R.B.D. The treatment consists of 10 nitrogen management practices for study of character associated with yield and yield contributing traits viz. recommended dose (RD) of nitrogen through fertilizer (120, 60, 40 kg NPK ha^-1), 75% RDFN, 50% RDFN+50% N through farm yard manure (FYM), 50% RDFN+50% N through Vermi-compost (VC), 50% RDFN+50% N through FYM+Azospirillum @ 5g kg^-1 Seed, 50% RDFN+50% N through FYM+Azotobacter @ 5 g kg^-1 seed, 50% RDFN+50% N through FYM+PSB @ 5 g kg^-1 seed, 50% RDFN+50% N through VC+Azospirillum @ 5 g kg^-1 seed, 50% RDFN+50% N through VC+Azotobacter @ 5 g kg^-1 seed and 50% RDFN+50% N through VC+PSB @ 5 g kg^-1 seed. The results revealed that the growth attributes and yield attributes was observed to be significantly higher under recommended application of nitrogen through inorganic fertilizer, closely followed by 50% RDFN+50% N through VC+Azotobacter @ 5 g kg^-1 seed. The 75% RD of N through fertilizer showed significantly inferior values for most of the above stated parameters.
