Effect of site specific nutrient management on productivity and profitability of rice in low land situation

Abstract

A field experiment was conducted for three Kharif season of 2014-16 at the Crop Research Station, Ghaghraghat Bahraich of Narendra Dev University of Agriculture and Technology, Kumarganj, Ayodhya to study the effect of site specific nutrient management on productivity and profitability of rice in low lands. Result revealed that application of 100% recommended dose of fertilizers (RDF) through inorganic fertilizers + vigore @ 625g/ha at 8 days after sowing (DAS) recorded significantly the higher values of growth, yield and yield attributes. This treatment increase the grain yield of rice to the tune of 21.5%, 7.5%, 5.6%, 96.1%, 37.9%, 28.2% and 138% over T1, T2,T3, T4, T5,T6, and T7 respectively. This treatment also had the highest nutrient uptake i.e. 108.5 kgN/ha, 35.4 kgP/ha and 121.4 kgK/ha followed by site specific nutrient management (SSNM) based on LCC-4(T3), and site specific nutrient management (SSNM) based on nutrient expert advise (T2). The gross income of Rs.68292/ha was highest with application of 100% RDF+Vigore @625g/ha at 8 days after planting (T8) but net income worth Rs. 29254/ha and B:C ratio(1.84) was recorded the highest with SSNM on LCC-4(T3) which was closely followed by 100% RDF+Vigore @625g/ha at 8 days after planting (T8) with net income of Rs.28134/ha and B:C ratio(1.70).
