Integrated Nitrogen Management through Different Sources on Growth and Yield of Wheat (Triticum aestivum L.).

A field experiment on study of nitrogen management through different sources on growth and yield of wheat (Triticum aestivum L.) was conducted during rabi season of 2016-17 at Agronomy Farm, B. A. College of agriculture, Anand Agricultural University, Anand on loamy sand soil. Nitrogen management on wheat var. GW 496 with ten treatments comprising of 100 % RDN, 75 % RDN along with 25 % N through FYM or vermicompost or 2% urea sprays at 30 and/or 40 and/or 50 DAS and 50 % RDN along with 50 % N through FYM or vermicompost or 2% urea sprays at 30 and/or 40 and/or 50 DAS into randomized block Design with four replications. Application of 75 % RDN + 2 % urea spray at 30, 40 and 50 DAS was found superior for growth and yield attributes viz; plant height at 60 DAS, number of spikelet spike-1, length of spike, number of grains spike-1, dry matter accumulation, test weight (48.78 g) and grain yield (6662 kg ha-1). However, treatment with 75% RDN + 25% N through VC recorded significantly higher plant height at harvest, number of total tillers, effective tillers and straw yield of wheat The highest net realization (Rs. 84643 ha-1) and BCR (3.95) were secured under treatment 75% RDN + 2% Urea spray at 30, 40 and 50 DAS.
