with three dates of sowing viz. November, 03, 10 and November, 17, 2011 and used three varieties of mustard viz. Vaibhav, Vardan and Varuna with four replication under Split Plot Design. Plant height, number of branches, number of siliquae, number of seed/siliquae, dry matter, seeds weight and yield were recorded at different growth stages. All the biometric parameters decreased with delay in sowing. Among the different varieties of mustard, Varuna showed higher plant height, more primary, secondary and tertiary branches, more dry weight and yield as compared to Vardan and Vaibhav. Higher seed yield (21.05 q/ha) was recorded under November, 03 date of sowing, when maximum and minimum temperature was 32.8 and 13.0 0 C respectively as compare to November, 17 (Maximum 30.2 0 C and Minimum 13.4 0 C) sown crop. Subsequently, sowing there was 12 and 22% increases in seed yield at November, 03 sowing over one and two week delayed sown crop. Among the varieties mean yield of Varuna yielded 20.06 q/ha and performed 8.3 and 12.3% higher yield than Vardan and Vaibhav, respectively. Net profit was calculated maximum (Rs 66265/ha) under 3 rd Nov. of sowing (D 1 ) over to 10 th Nov.(D 2 ) and 17 th Nov. (D 3 ) as well as the net profit was received among the varieties Varuna was produces maximum (Rs.61621/ha) over to Vardan (Rs 54266.00/ha) and Vaibhav (Rs 50596/ha).
