Effect of nitrogen sources on yield and economics of mustard

Abstract

A field experiment was conducted at Research farm, Vivekananda Global University, Jaipur during Rabi season¸ 2023-24 on loamy sand soil. The experiment comprises nine treatments of different nitrogen sources (100% RDN (80 kg N) through chemical fertilizers, 100% RDN through Vermicompost, 100% RDN through Biogas slurry, 100% RDN through Poultry Manure, 75% RDN through chemical fertilizers + 25% through Vermicompost, 75% RDN through chemical fertilizers + 25% through Biogas slurry, 75% RDN through chemical fertilizers + 25% through Poultry manure, 50% RDN through chemical fertilizers + 25% through Poultry manure + 25% through Vermicompost, 50% RDN through chemical fertilizers + 25% through Biogass slurry + 25% through Vermicompost, 50% RDN through chemical fertilizers + 25% through Poultry manure + 25% through Biogass slurry and 1/3 RDN through Each Vermicompost, Biogas Slurry and Poultry Manure) was laid out in randomized block design and replicated thrice. Results indicated that among the treatments applied as application of 75% RDN through chemical fertilizers + 25% through vermicompost recorded significantly higher seed (1783 kg ha-1) and stalk (6345 kg ha-1) yield, net return (Rs. 70032) and B:C ratio (3.27).
