Abstract
An experiment was conducted at the Crop Botany Field Laboratory, Bangladesh Agricultural University, Mymensingh, from November 2010 to February 2011 to assess the effect of a single weeding on crop growth and yield of two mustard species, Brassica napus and Brassica campestris. The experiment comprised four treatments from the combination of those two species along with one hand weeding on 40 days after sowing (DAS) or without weeding (i.e. control). The experiment was laid out following a Randomized Complete Block Design with three replications. Weeding and species interaction had significant effect on most of the growth characters and yield. One hand weeding on 40 DAS remarkably suppressed the weed growth for the subsequent stages. The results indicated that both species gave higher yield due to the operation of a single weeding as compared to without weeding. The highest seed yield, 1.48 t ha-1 was obtained from the crop treated with one hand weeding whereas the lowest yield 1.08 t ha-1 was observed in un-weeded control treatment. In context of species, the higher seed yield 1.31 t ha-1 was found in Brassica campestris and that of lower seed yield 1.25 t ha-1 was found from Brassica napus.
