Studies were conducted for two years (1983–84) to see the relative efficiency of Ankur (a liquid nitrogenous fertiliser) vis-a-vis urea on transplanted rice (Oryza sativa L. var. P.R.106). Higher rice grain yields were obtained at 120 kg N ha−1 with urea than with Ankur. However, Ankur was as efficient as urea at the lower level of 60 kg N ha−1. Among the different time and methods of application, Ankur sprayed in three equal splits at transplanting, three and six weeks after transplanting was found superior to other treatments. Tile total N uptake (grain + straw) was found higher due to urea than with Ankur. When Ankur was applied with urea at 60 kg Nha−1 the total N uptake wasfound slightly higher than Ankuralone. Grain yield was found to be correlated highly with N content at panicle initiation, total N uptake and total dry matter yield.
