Abstract
Four varieties/advanced lines of brassica species, two from Napus (NIFA-Gold and NH-97-5/2-4) and two from Juncea (NIFA-Raya and 7x1/05-4) were tested in a field experiment at NIFA experimental farm. The experiment was laid out according to split plot design, keeping varieties/lines in main plot and boron (B) levels in sub plot. Basal dose of NPK was applied to the experiment at the time of sowing. Different levels of boron were applied as foliar on crop in three splits at vegetative growth, flowering and pod formation stage. The results showed that maximum increase in seed yield (23.8%) was recorded for NIFA-Gold and NIFA-Raya by the application of 700 g B ha-1 followed by an advanced line of juncea 7x1/05-4 yielded (20.8%) more than control at 1000 g B ha-1 , while minimum (19.3%) increase over control in seed yield was recorded in NH-97-5/2-4 at 700 g B ha-1 . Boron concentration in brassica leaves increased with the increase in boron application dose and 100 ± 5 ppm boron concentration in plants leaves was found ideal/optimal.
