Abstract:
A field experiment was conducted in the farmers’ fields of Hosahalli village tank command area, Hassan district, Karnataka, during the kharif season of 2021, at different organic carbon levels to assess the performance of paddy under different STCR based fertilizer recommendations. The experiment was laid out in split plot design with three replications. Main plot consisted of 3 organic carbon levels viz., High (>0.75%), Medium (0.50-0.75%) and Low (<0.50%). The sub plots consisted of 4 fertilizer levels in which 3 STCR based fertilizer recommendations for targeted yields of 40, 50 and 60 q ha^-1, compared with farmer’s practice. Significantly higher growth parameters viz., plant height, number of tillers and leaf area were recorded with STCR fertilizer recommendations for 60 q ha^-1 targeted yield followed by 50 q ha^-1. The highest grain yield (53.59 q ha^-1) and straw yield (80.36 q ha^-1) were recorded with STCR fertilizer recommendations for 60 q ha^-1 targeted yield. Effect of organic levels and their interaction with STCR fertilizer recommendations did not show significant influence on growth and yield of paddy.
