Abstract

                                The experiment conducted with thirty rice cultivars revealed that there are cultivar differences in drymatter, grain yield, growing degree days and heat unit efficiency. The heat unit efficiency depended upon the duration, drymatter and prevailing temperature. The cultivar IET 7590 and IET 7301 were screened for their better heat unit efficiency for dry matter and grain yield, respectively. This study suggests that the heat unit efficiency can be used as a measure of crop efficiency for temperature utilisation.
