Abstract
The experiment was conducted at Agricultural Research Station, Bapatlain kharif2014 and 2015 to find out the effect of nitrogen levels on yield components and yield of BPT 2270 Bavapurisannalu. The experiment was laid out in a randomized block design with 7 treatments replicated thrice. Seven levels of nitrogen (80, 120, 160, 200, 240,280 and 320 kg N ha-1) were used as an experimental treatments.Results revealed that nitrogen had significant positive effect in terms of tillers hill-1, grains panicle-1 grain yield, straw yield and economics. The results revealed that application of 320 kg N ha-1 recorded significantly the highest yield attributing characters like productive tillers plant-1, panicle length, number of filled grains per panicle and grain yield (5496 and 5738 kg ha-1) while lowest yield was recorded with 80 kg N ha-1 treatment. Highest net returns and benefit cost ratio was recorded with 240 kg N ha-1during 2014 and 2015. It can be indicated that application of 240 kg N ha-1 is more economical to the BPT 2270 long duration variety in both the years of experimentation.
