Abstract

Field experiment was conducted during the rabi season of 2013-14 at Instructional Cum Research farm of Assam Agricultural University, Jorhat, Assam, India to study the response of rapeseed (Brassica  campestrisvar.toria) varieties to varying levels of irrigation under late sown
conditions. Results revealed that production of seed, stover and oil yield increased up to the three irrigations at 20 days after sowing (DAS), flowering and siliqua formation stages, which were significantly higher than those with one irrigation at flowering and rainfed crop. However, crop performance with three irrigations and that of two irrigations (at flowering and siliqua formation) recorded similar yield performance of Rapeseed. Whereas, the maximum water use efficiency was observed under one irrigation at flowering. Considering varieties, the variety TS 67 being at par with TS 38 recorded significantly higher seed and stover yields than those of M 27 and TS 46.
