A Field trial was conducted during 1988–89 and 1989–90 at Water Management Research Station, Memari. Bidhan Chandra Krishi Viswavidyalaya, Burdwan, to study the effect of three different irrigation regimes, namely rainfed (I 1 ) (No irrigation), one irrigation (I 2 ) at flowering and two irrigations (I 3 at flowering and at sihqua formation stages) on the grain yield and water expenses on four different rapeseed‐mustard cultivars, namely Pusa Bold, Pusa Baroni, Varuna and DIR 247. The variety DIR 247 recorded maximum grain yield (12.1 qha‘) followed by Pusa Baroni (11.8 q ha −1 ). The variety Varuna showed the lowest water use efficiency (48.1 kg ha −1 cm −1 ) while DIR 247 showed the maximum value of 57.0 kg ha −1 cm −1 . The number of irrigations significantly increased the grain yield. Two irrigations, one at flowering and at siliqua formation stage increased grain yield by 28 % over the rainfed plots. During the crop growth period the actual water expenses among the cultivars in any moisture regime were more or less similar. The interaction between varieties and irrigation levels were, however, not significant.
