EFFECT OF SOWING TIME ON GROWTH AND YIELD OF MUSTARD (Brassica spp.)

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 2 =2 nd sowing (11 th November), S 3 =3

November) and S 4 = 4 th sowing (1 st December), and two varieties of mustard viz. V 1 = 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 2 , siliqua plant -1 and seeds silliqua -1 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 -1 ) was obtained from BARI Sarisha-16. The tallest plant was recorded from the treatment with S 2 = 2 nd sowing (11 th November). The maximum number of branches per plant, number of siliquae per plant, length of siliqua were found in 2 nd sowing treatment (11 th November). The maximum yield of seed (1.95 tha -1 ) was obtained from 2 nd rd 1 =1 sowing (21 . sowing time treatment (11 November).The combinations of variety and sowing time had significant effect on almost all the parameters. The highest yield of seed (2.387tha -1 ) was obtained from BARI Sorisha-16 and S 2 = 2 nd sowing time (11 th November) treatment combination. The highest yield of stover per hectare and biological yield per hectare was obtained from treatment combination of BARI Sarisha-16 and S

sowing time.
