Influence of crop establishment methods and nutrient management practices on productivity and profitability of red rice in wet-temperate north-western Himalayas
Keywords:
Organic farming, net returns, nutrient management, productivity, profitability, red riceAbstract
To assess the impact of different crop establishment methods (CEMs) and nutrient management practices (NMPs) on red-rice variety ‘HPR-2720’ under north-western Himalayas (NWH), a field experiment was conducted during kharif seasons of 2021 and 2022 at Palampur. Three CEMs viz., SRI, ARS and TR in main-plots and four NMPs, viz. Control, organic management, natural farming management, and integrated management as sub-plot treatments were laid out in split-plot design, replicated-thrice. The higher rice grain yield, straw yield, and biological yield along with maximum net returns and B:C ratio were recorded with SRI and TR followed by ARS. Among NMPs, integrated management [75% NPK + 25% N through FYM + Azospirillium+ PSB (seed treatment)] recorded significantly higher grain yield of 2.5 and 2.3 t/ha during 2021 and 2022, respectively followed by organic management. SRI under INM and OF was found suitable and remunerative for farmers with small land holdings in North-Western Himalayas.
