Abstract: A field experiment was conducted at Crop Research Station (NDUAT), Masodha, Faizabad during kharif 2011 & 2012 to access the effect of nursery nutrient management on yield and attributing traits of Swarna and Swarna Sub-1 in submergence/flood prone ecosystem of eastern Uttar Pradesh. The experiment was comprised of seven different nutrient combinations viz. T1 - N₁₀₀:P₅₀:K₀ kg/ha_, T2 - N₆₀:P₄₀:K_­40 kg/ha_, T3 - N₂₀:P₄₀:K₄₀ kg/ha_, T4-N₂₀:P₄₀:K₆₀ kg/ha_, T5 - N₂₀:P₆₀:K₄₀ kg/ha_, T6 - N₀:P₆₀:K₄₀ kg/ha and T7-N₀:P₄₀:K₆₀ kg/ha in nursery plots. Highest grain yield of rice (38.28 q/ha) during 2011 and (38.46 q/ha) during 2012 was obtained under variety Swarna Sub1 with nursery nutrient treatment T₄- N₂₀P₄₀K₆₀. The economic analysis also exhibits profitability of this treatment combination (T₄- N₂₀P₄₀K₆₀) over the other treatments with submergence tolerant rice variety Swarna Sub-1. Maximum benefit: cost ratio of 1.79 and 1.83 during both respective years was recorded under combination of variety Swarna Sub1 and T₄- N₂₀P₄₀K₆₀ nutrient treatments.
