Abstract:
The experiment was conducted during November 2017 to February 2018 to find
out the effect of sowing time on growth and yield of mustard (Brassica spp). In
this experiment, the treatments consisted of four different Sowing time viz. S
sowing (1
st
November), S

nd
sowing (11

November), S

4
= 4
th
sowing (1

December), and two varieties of mustard viz.
V

= BARI Sarisha-16, V
= BARI Sarisha- 17. The experiment was laid out in
two factors Randomized Complete Block Design (RCBD) with three replications.
N, P, K, S, Zn and B were applied according to recommended doze. The collected
data were statistically analyzed for evaluation of the treatment effect. The highest
plant height was produced with BARI Sarisha-16. The maximum branches plant

were recorded from BARI Sarisha-16. The
maximum thousand seed weight was recorded from BARI Sarisha-16
The highest
yield of seed (1.32 ton ha

) was obtained from BARI Sarisha-16. The tallest plant
was recorded from the treatment with S

maximum number of branches per plant, number of siliquae per plant, length of
siliqua were found in 2

of seed (1.95 tha

almost all the parameters. The highest yield of seed (2.387tha
