Effect of different nitrogen levels on crop growth of various rice cultivars

Abstract

An experiment were done to analyze the effect of different nitrogen levels on crop growth of various rice cultivars with different rice varieties. Six cultivars from rice (Naveen, Indira, Ratna, Surendra, Birupa and Daya) were evaluated in the kharif season 2017-2018. The experiment were conducted in factorial randomized block design with three replications. Among the cultivars of rice, the effect of nitrogen levels on crop growth rate found to be proportional till the vegetative stage and then diminishing effect on crop growth rate is observed during reproductive stage. The highest CGR was observed in naveen and birupa and lowest in daya and surendra
