Effect of nutrient management practices in farmers field of Lowland rice for enhancement of Productivity, profitability and energetic under Mid altitude of Nagaland
nutrient management practices for improving Lowland ricef Productivity
Abstract
On Farm trail was conducted in Longleng district of Nagaland during 2014-15 and 2015-16 to find out the most suitable nutrient management practices Viz. recommended doses of fertilizers (RDF) 80:60:40 Kg NPK per ha, locally available weed biomass (Eupatorium) @ 10 t/ha and farmers practics at farmers field under Krishi Vigyan Kendra Longleng. Data collected were growth and yield parameters. Plant height, and tillers/m2, grains/panicle, panicle length, panicle weight and 1000-grain weight. The experiment was laid out in Complete Randomized Block Design. The mean data of all the observation over two years were pooled and statistically analysed. The result revealed that the growth and yield parameters were recorded maximum under RDF and followed by Eupatorium @ 10 t/ha as compared to farmers practice. Maximum grain yield was recorded 3590 kg/ha, 3270 kg/ha and 2730 kg/ha with RDF, weed biomass@10t/ha and farmers practices respectively. Grain yield was increased by 31.5 % in RDF and 11.8 % in Eupatorium @ 10 t/ha as compared to farmers practice. Production efficiency was recorded highest with RDF (28.0 kg/ha/day), Eupatorium @10 t/ha (25.5 kg/ha/day) and farmers practice (21.3 kg/ha/day). Maximum net return and benefit cost ratio were recorded Rs.18850/ha, 1.91 with RDF treatment as compared to other treatments. Economic efficiency was found highest under RDF (Rs.147.27/ha/day) followed by Eupatorium @10 t/ha (Rs.128.36/ha/day) and farmers practices (85.70/ha/day). Hence, the farmer’s practices can be replaced with the adoption of RDF or locally available weed biomass (Eupatorium) for higher productivity and income of the District.
