Abstract
The research was conducted during rabi seasons of 2022-23 and 2023-24 at College Farm, Navsari Agricultural University, Navsari, India. Nine integrated nutrient management treatments were applied to grain amaranth crop in rabi season (mid-November and harvested in April/May) and replicated three times in randomized block design. Almost all the growth attributes, yield attributes, and quality were significantly improved due to combination of organic manures and inorganics. Significantly higher grain yield (1371 kg/ha) and stover yield (2916 kg/ha) were recorded under the application of vermicompost 5 t/ha + 100% RDN through inorganic fertilizer (T6). However, this yield was at par with the application of biocompost 5 t/ha + 100% RDN through inorganic fertilizer (T4) and application of FYM 5 t/ha + 100% RND through inorganic fertilizer (T2) in pooled analysis of 2022-23 to 2023-24. Application of biocompost 5 t/ha + 100% RDN through inorganic fertilizer (T4) gave maximum profitably higher net returns (₹ 65768) and BCR (2.67) among all the treatments.
