An experiment was conducted during 1998–99 to study the effect of sowing time (October 1O, October 30, Novemper20, December 10) and plant densities (333, 222, 167, 167, 111 and 83 thousand plants/ha) on phenology and growth of African sarson (Brassica carinata A.Br.). The experiment was laid out in spilt plot design with four replications keeping dates of sowing in main plot and plant densities in sub plots. Sowing dates had a significant influence on both phenology and growth of African sarson. The early sown crop took less number of days for emergence while late sowncrop took more number of days. There was drastic reduction in vegetative phase when sowing was delayed to November 20 and December 10. The reduction in reproductive phases was less drastic. The varied plant densities did not have any significant influence on phenological behaviour of the crop.
