Abstract
A field experiment was conducted at Agricultural Research Station, kampasagar, Nalgonda, Telangana during kharif 2011 and kharif 2012 to study the response of transplanted rice to four levels of Nitrogen (0, 120,160 and 200 kg N ha-1) and four levels of Phosphorous (0,30,60 and 90 kg ha-1). The experiment was designed in Randomized Block Design and replicated thrice. 120 kg N ha-1 recorded significantly higher tiller and panicle number, more filled grains panicle-1 and 1000 grain weight than 0 kg N ha-1 and on par with other higher doses.120 kg N ha-1 recorded significantly higher grain yield (4750 kg ha-1 and 5388 kg ha-1) than 0 kg N ha-1 (3647 and 3812 kg ha-1) and it was comparable with 160 kg N ha-1 (4937 and 5514 kg ha-1) and 200 kg N ha-1 (5015 and 5591 kg ha-1). Phosphorous applied at different levels did not influence significantly on yield attributes and grain yield during both the years. NPK uptake was significantly higher at 120 kg N ha-1 than 0 kg N ha-1 and identical with other higher doses in straw and grain. High NNG and NPE were attained at 120 kg N ha-1 and above doses than control. Reverse trend of NUEPG was obtained with increase in N doses from 0 to 200 kg N ha-1
