Effect of nursery nutrient management on yield and economics of Swarna and Swarna-Sub 1 in submergence prone ecosystem of eastern Uttar Pradesh

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:K­40 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.
