Influence of different nutrient management approaches on growth parameters of dry direct seeded rice (Dry- DSR) in TBP command area

Abstract

An experiment was conducted during kharif-2016 at ARS, Dhadesugur with ten treatments and three replications to evaluate the response of dry direct seeded rice to major nutrients in a vertisol of Tunga Bhadra Project command area. The Results revealed that significantly higher plant height and number of tillers were recorded with nutrients applied through Site Specific Nutrient Management approach fallowed by Soil Test Crop Response approach compared to absolute control. Whereas, the treatments Soil Test Laboratory method and farmer’s practice showed on par with each other at 60 DAS, 90 DAS,120 DAS and Harvest. Significantly higher dry matter production was recorded at 120 DAS of crop. The higher dry matter was recorded in site specific nutrient management followed by recommended dose of fertilizer K Omission with recommended dose of N and P as per Soil Test Laboratory method.
