Effect of Different Nitrogen and Potassium Levels on Yield and Nutrient Uptake of RNR 15048 during Summer Season in Southern Odisha

Abstract

Background: The low glycemic rice variety RNR 15048 was introduced in Southern Odisha recently but the nitrogen and potassium requirement was not worked out for rabi / summer season. Methods: In this study, RNR 15048, a low glycemic index rice variety, was conducted in a split plot design with four main plots at 0, 50, 100 and 150 kg of nitrogen per hectare and three subplot levels at 0, 30 and 60 kg of potassium per hectare, each of which was reproduced three times. Result: A significant increase in yield, yield components and NPK uptake was noted with increase in nitrogen levels from 0 to 50, 100 and 150 kg/ha and potassium levels from 0 to 30 and 60 kg/ha.
