Effect of Enriched FYM and Fertilizer Levels on Yield and Economics of Aerobic Rice (Oryza sativa L.)

Studies were conducted to evaluate the effect of enriched farm yard manure and fertilizer levels on yield and economics of aerobic rice, results showed that application of 125: 62.5: 62.5 NPK kg ha⁻¹ recorded higher grain yield (53.54 q ha⁻¹) and filled grain (111.86) but less unfilled grains panicle^{1(12.83) recorded in application 75: 37.5: 37.5 NPK kg ha−1 which was on par with level 100: 50: 50 NPK kg ha−1 (12.26). Significantly higher 1000 grain weight (23.37 g) recorded in application of 100: 50: 50 NPK kg ha−1which was on par withlevel 75: 37.5: 37.5 NPK kg ha−1 (22.78 g). Among the methods of application spot application of enriched manure recorded significantly higher 1000 grain weight (24.24 g) and grain yield (54.03 q ha−1) due to timely available of nutrients. Interaction of spot application of enriched manure with 125: 62.5: 62.5 NPK kg ha−1 has registered higher grain yield (60.58 q ha−1) and filled grains panicle−1 (128.75). Significantly higher 1000 grain weight (25.80 g) in spot application of enriched manure with 100: 50: 50 NPK kg ha−1. Higher gross returns (Rs. 90, 870 ha−1), net returns (Rs. 65, 319.74 ha−1) and B: C ratio (1: 2.56) was observed in spot application of enriched manure with fertilizer level 125: 62.5: 62.5 NPK kg ha−1.}
