Abstract

A field experiment was conducted during kharif 2017 and 2018 at ICAR-Indian Institute of Rice Research, Rajendranagar, Hyderabad to study the effect of different nitrogen management practices on the yield and yield attributes of rice under different establishment methods. The experiment was laid out in split plot design with two establishment methods [Normal transplanting (M1) and mechanized SRI (M2)] in main plots and six nitrogen management practices [N1- Nutrient Expert based recommendation of nitrogen with neem coated urea, N2- Nutrient Expert based recommendation of nitrogen with neem coated urea (75%) +
vermicompost (25%), N3- Recommended dose of nitrogen with neem coated urea, N4- Recommended dose of nitrogen with neem coated urea (75%) + vermicompost (25%), N5- N omission, N6- Absolute control (No N, P and K fertilizer application)] in sub-plots with three replications. The results revealed that yield and yield attributes of rice did not vary significantly due to establishment methods. Among nitrogen management practices, application of nitrogen as per recommendation of Nutrient Expert with neem coated urea (75%) + vermicompost (25%) (N2) recorded significantly higher yield and yield attributes (Number of panicles m-2, panicle length, panicle weight and test weight) as compared to that of nitrogen omission (N5) treatment and absolute control (N6) where as it was found at par with all other nitrogen management practices (N1, N3 and N4).
