Effect of organic nutrient management on productivity and economics of scented rice

Field experiments were conducted at Ranchi, Jharkhand to study the effect of organic nutrient management on productivity and economics of scented rice indicated that scented rice (Birsamati) grown with 100:21.8:20.8 Kg NPK ha⁻¹ through inorganic fertilizer produced maximum grain (3.95 t ha⁻¹) and straw yield (5.55 t ha⁻¹), net return (39,557 ha⁻¹), and benefit: cost ratio (3.62), with higher value of yield attributing characters. Among various organic sources, use of green manuring @ 5 t ha⁻¹ + farm yard manure @ 10 t ha⁻¹ produced maximum grain (3.28 t ha⁻¹) and straw yield (4.35 t ha⁻¹), maximum net return (35,975 ha⁻¹) and benefit: cost ratio (2.61) compared to rest of the organic treatments.
