A field experiment was conducted during the winter seasons of 1996 97 and 1997 98 at the Crop Research Centre, Pantnagar, to study the effect of different fertility levels on yield attributes, seed yield, haricots index, oil content and oil yield of promising Brassica varieties. Brancheslplant (31.86), seed weightlplant (4.75 g), 1,000 seed weight (4.4 g), seeds/siliqua (9.7) and seed yield (1,350 kg/ ha) were highest in PBC 9221 ( Kiran ) of Brassica carinata A.Braun whereas harvest index (1 6.7%) was lower in this variety. Oil content of Kranti Brassica juncea (L.) Czernj. Cosson was higher but oil vield was higher in BC 9221 Brassica carinata. Variety DLSC 1 had higher FUE (N) (43.6) and Kranti recorded lower (1.7) FUE (N) compared with PR 8988 . With each successive increase in fertility level up to 125% of the recommended, the FUE (N) increased. With the application of fertilizer, oil content decreased and, contrary to it, oil yield increased owing to higher seed yield of pronounced yield contributing attributes.References
