Abstract:
A field experiment was conducted during the kharif season 2022 at Agriculture research farm, Maharishi Markandeshwar (Deemed to be University), Mullana, Haryana. The experiment conducted in a factorial randomized block design with five treatments and three replications. Three non-scented rice varieties V₁: HKR-47, V₂: HKR-48 and V₃: PR-126 were taken with 5 treatments T₁: Control, T₂: 100% RDN through urea, T₃: 75% RDN through urea + 25% N through vermicompost, T₄: 50% RDN through urea + 50% RDN through vermicompost, T₅: 25% RDN through urea and 75% RDN through vermicompost. Early duration variety PR-126 responded well to INM approach and recorded significantly higher grain yield (52.87 q ha^-1), straw yield (66.27 q ha^-1) and Harvest index (44.07%). Among the treatments, T3: (75% RDN through urea + 25% RDN through vermicompost) gave higher values in all parameters. Thus, fertilizing the crop with 75% RDN through urea + 25% through vermicompost have been found beneficial. Among varieties V₃: PR-126 gave the highest net return (Rs 64,634/ha) and B: C ratio (2.22) as compared to other two varieties.
