EFFECT OF SOURCE OF NITROGEN AND WEED CONTROL METHOD ON THE PERFORMANCE OF MUSTARD

Abstract

The experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University. Dhaka during the rabi season from November 2014 to February 2015 to study the effect of source of nitrogen and weed control method on the performance of mustard cv. BARI Sarisha-14. The treatment consisted of four sources of nitrogen viz. N 0 = no = NPK mixed fertilizer and N 3= Urea super granule, and three different weeding methods viz. W o = No weeding, W1 = hand weeding nitrogen (Control), N 1 = Prilled urea. N, - and W-,= Uerbicidal weeding. The experiment was laid out in a Split plot design with three replications. Results showed that a significant variation among the treatments in respect majority of the observed parameters. The tallest plant (56.16 cm) was recorded with prilled urea. The maximum number of branches per plant (5.17), number of siliquae per plant (26.34) and number of seeds per silliqua (29.06) were also produced by prilled urea. The highest seed yield (1139.00 kg hi') was obtained from prilled urea. On the other hand, the tallest plant (55.49 cm) of mustard was produced with hand weeding. The maximum number of branches per plant (4.63), number of siliquae per plant (22.75) and number of seeds per silliqua (26.31) was obtained from hand weeding. The highest seed yield (1040.00 kg hi') was also obtained from hand weeding. The interaction effect of nitrogen and weeding had significant effect on almost all parameter. The highest seed yield (1382.00 kg hi') was obtained from prilled urea with hand weeding interaction treatment.
