Transplant gobhi sarson for higher yield under late sown conditions

摘要

Rapeseed and mustards are the major rabi oilseed crops occupying prominent place both in area and production. India is one of the largest producers of rapeseed and mustard. In Punjab, these crops are grown over an area of 70 thousand acres, having production and productivity 33 thousand tonnes and 4.7 q/acre, respectively. Gobhisarson, a rapeseed crop gained special importance because of high yield potential and higher quality oil. Canola gobhi sarson, an improved version of rapeseed, contains oil (<2% erucic acid and <30 micromoles of glucosinoiates) as compared to other old varieties of rapeseed and mustard (having >50% erucic acid and >130 micromoles of glucosinoiates). The higher erucic acid in edible oils inhibits the cholesterol metabolism and causes deposition in body, increases the pungency and lowers the keeping quality of oil. Canola oil is now gaining importance because its consumption is useful for human health especially for cardiac patients. Gobhi sarson crop can be raised through transplanting techniques where transplanting is delayed due to basmati rice or cotton-based cropping system without reduction in yield.
