EFFECTS OF NITROGEN AND SULFUR ON THE GROWTH, YIELD AND OIL CONTENT OF SESAME

Abstract

An experiment was conducted in the field of Sher-e-Bangla Agricultural University farm, Sher-e-Bangla Nagar, Dhaka, Bangladesh during the period from February to May, 2009 to determine the effect of nitrogen and sulffir on growth and yield of sesame. The experiment consisted of two factors. There were 4 levels each of nitrogen (0, 40, 60, 100 kg N ha1 ) and sulfi.ir (0, 20, 40 and 60 kg S hi t ). The experiment was laid out in Randomized Complete Block Design with three replications. Plant height, number of branches, number of leaves, seed yield, stover yield and oil content increased significantly with increasing N level upto 60 kg N/ha (N 2 ) whereas the concentration of N, P. K and S in plant increased upto 100 kg N/ha. The seed yield, stover yield and oil content at 60 kg N/ha were 1.31 tlha, 3.05 tTha and 42.80%, respectively. On the other hand, plant height, number of branches, number of leaves, seed yield and oil content were increased significantly with increasing S level upto 40 kg S/ha (S2 ) whereas stover yield, N, P, K and S concentration in plant increased upto 60 kg S/ha. The maximum seed yield (1.21 tlha) was obtained at 40 kg S/ha and the maximum stover yield (3.14 tlha) and oil content (43.13%) were observed at 60 kg S/ha. In terms of seed yield, stover yield and oil content the combination N 2S2 (60 kg N/ha and 40 kg S/ha) was found most suitable.
