Abstract: 

A field experiment was carried out at the research farm of A. S. (PG) College, Lakhaoti, Bulandshahr, (U.P.) during winter 2009-10 and 2010-11. The soil of experimental field was sandy loam and slightly alkaline in reaction (pH 7.7). The treatments consisted of four irrigation schedules viz. I0- no irrigation, I1- one irrigation at pre-flowering, I2- one irrigation at pod filling, I3- two irrigations one each at pre-flowering and pod filling, three phosphorus levels viz. P0- control, P30- 30 kg P2O5 ha-1, P60- 60 kg P2O5 ha-1 and three sulphur levels viz. S0- control, S20- 20 kg S ha-1 and S40- 40 kg S ha-1. The treatments were laid out in split plot design and replicated thrice. The result revealed that plant height, dry matter, number of branches, siliquae plant-1, 1000-seed weight, seed yield and oil content was observed significant with the application of 60 kg P2O5, 40 kg S ha-1 and two irrigations one each pre–flowering and pod filling stage.
