ABSTRACT
A thrice replicated field trial was conducted in rabi season 2012-13 at SVPUAT Meerut to evaluate different INM module for yield maximization, the experimental results revealed that plant height, number of tillers m-2, dry matter accumulation at 30 DAS and at harvest, and 1000 grain’s weight showed an increase with increase in the NPK fertilizer levels. 125% RDF recorded significantly highest grain yield (3.61t ha-1) and straw yield (4.68 t ha-1). Moreover, application of 125 % NPK was recorded 48.1, 42.6 and 50.0 % available N, 122.2, 125.7 and 174.5 % available P and 48.9, 33.0 and 33.7 % available K at 30, 60 DAS and at harvest, respectively as compared to control and maximum uptakes of N (56.72 and 25.30 kg ha-1), P (9.75 and 6.55 kg ha-1) and K (25.29 and 74.94 kg ha-1) in grain and straw, respectively. Furthermore, higher benefit cost ratio was also fetches by the application of 125 % NPK.
