Abstract

Field experiments were conducted on three different Brassica spp. (Brassica juncea, Brassica carinata and Brassica nupus) with three levels of nitrogen (40, 80 and 120 kg of N ha^-1) and 2 methods of time of potassium application at 80 kg ha^-1 ((i) 100% basal and (ii) 50% basal + 50% at the time of 1st irrigation), during Rabi season of 2003 - 2004 and 2004 - 2005 showed that Brassica spp. responded significantly to the application of N and K. Maximum oil yield was observed in case of B. carinata (PBC-9221) and minimum under B. napus. Higher dose of nitrogen 120 kg N ha^-1 produced maximum oil yield. Split application of potassium also produced higher oil yield than basal dose of potassium.

Key words: Brassica, nitrogen, potassium.
