Rice, the major staple food crop and ranked first as cultivated crop in Nepal, has productivity of 3.36 t ha-1. Nitrogen (N) is one of the most important factors limiting its yield. A field experiment was conducted in Lumle, Kaski, Nepal from June-November 2016 to investigate Performance of temperate rice under different levels of nitrogen application in rice variety (Lumle-2). The experiment was laid out in randomized complete block design with five treatments (0, 50, 100, 130, 150 Kg N ha-1 ) and replicated four times. The yield attribute, number of seeds per panicle was significantly higher when soil was applied with 130 Kg N ha-1 leading to higher grain yield. At N level 150 Kg ha-1, plant height, number of tillers per meter square and panicle length were found to be higher than the lower levels leading to higher straw yield. So, the productivity of rice can be significantly increased by applying optimum level of N fertilizer i.e. 130 Kg N ha-1.
