Abstract :
To study the effect of nitrogen application timings on Brassica cultivars, an experiment was conducted at New Developmental Farm, University of Agriculture, Peshawar, during winter 2011-12. The experiment consisted of three Brassica cultivars (Abasin-95, Dure-e- NIFA and NIFA Raya), three nitrogen application timings (all at sowing, half each at sowing and flowering, one third each at sowing, flowering and pod formation). Different cultivars showed significantly varied response for weed fresh and dry weight and seed yield. Abasin-95 cultivar showed the strong weeds growth suppression and resulted in lower weeds fresh and dry weight of the weeds and also produced higher seed yield. Nitrogen applied in two or three splits doses resulted in higher Brassica seed yield. Cutting declined weeds fresh and dry weight and seed yield of Brassica.
