EFFECT OF DIFFERENT SOWING METHODS AND VARIETIES ON THE YIELD OF MUSTARD (Brassica campestris L.) A THESIS

Abstract

The experiment was carried out at Sher-e-Bangla Agricultural University Farm, Dhaka-1207, Bangladesh during Rabi season, November 2017 to February 2018 to find out the effect of different sowing methods and varieties on the yield of (Brassica campestris). The experiment comprised of two factors - the treatment consisted of four sowing methods viz. S 0 = Broadcast method, S = Line to line space 20 cm, S 2 = Line to line space 25 cm and S = Line to line space 30 cm and three different varieties viz. V 1 = BARI Sarisha 14, V 3 2 1 = BARI Sarisha 15 and V = BARI Sarisha 17. The experiment was laid out in two factors Randomized Complete Block Design (RCBD) with three replications. The collected data were statistically analyzed and a significant variation among the treatments was found in respect of majority of the observed parameters. The highest plant population was recorded from Broadcast method of sowing. The tallest plant was recorded from the plot of broadcast method. The maximum branches plant , dry matter weight plant -1 , siliqua plant -1 and seed silliqua -1 were recorded from the treatment line to line space 30 cm. The maximum thousand seed weight (2.97 g) was recorded from the broadcast method . The maximum yield of seed ha (1.11 t) was obtained from broadcast method. The highest plant population (77.25) was observed in case of BARI Sarisha 14. The tallest plant of mustard was found in case of with BARI Sarisha 15. The maximum branches plant -1 , dry matter weight plant -1 , siliqua plant -1 , seed silliqua -1 , and length of silliqua were obtained from BARI Sarisha 15. The highest yield of seed (0.95 t/ha) was obtained from BARI Sarisha 15. The combinations of different sowing methods and different varieties had significant effect on almost all the parameters. The highest biological yield per hectare (5.08 tones) was obtained from broadcast method with BARI Sarisha 15 treatment combination.
