A field experiment was carried out to examine the effect of different irrigation levels on growth and yield of canola in 2005-06. The experiment comprised nine irrigation treatments viz., one irrigation at early vegetative stage (21 DAS); one irrigation at flower initiation (56 DAS); one irrigation at seed formation (93 DAS); two irrigations, one at early vegetative and second at mid vegetative stage (21 & 35 DAS); two irrigations, one at early vegetative and second at flower initiation (21 & 56 DAS); two irrigations, one at flower initiation and second at seed formation (56 & 93 DAS); three irrigations, one at early vegetation, second at mid vegetation and third at seed formation (21, 35 & 93 DAS); three irrigations, one at early vegetation, second at flowering and third at seed formation (21, 56 & 93 DAS); three irrigations, one at mid vegetation, second at flowering and third at seed formation (35, 56 & 93 DAS). The results showed that maximum crop growth rate, net assimilation rate, number of seeds per siliqua, 1000-seed weight and seed yield were attained with three irrigations at early vegetative, flowering and seed formation (21, 56 & 93 DAS). The oil and protein contents of the seed were not affected significantly by varying irrigation levels.
