摘要
背景:最近在南奥里萨邦引进了低血糖水稻品种RNR 15048，但没有计算出夏季氮素和钾的需用量。方法:以低血糖指数水稻品种RNR 15048为试验材料，采用分块设计，设4个施氮量分别为0、50、100和150 kg /公顷的主区和3个施钾量分别为0、30和60 kg /公顷的小区，每个小区重复3次。结果:施氮量从0增加到50、100和150 kg/ha，施钾量从0增加到30和60 kg/ha，产量、产量组成和氮磷钾吸收显著增加。
Effect of Different Nitrogen and Potassium Levels on Yield and Nutrient Uptake of RNR 15048 during Summer Season in Southern Odisha
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.
