摘要：A pot experiment was conducted at the experimental space of Botany Department, Jahangirnagar University, Savar, Dhaka during rabi season 2004-2005 to determine the effect of nitrogen (N) on yield, protein content and nutrient uptake of soybean using G-2 (Bangladesh soybean-4) as test crop. Rates of N used were 0 (N 1 ), 10.58 (N 2 ), 15.87 (N 3 ), 21.16 (N 4 ), 26.45 (N 5 ) and 31.74 (N 6 ) kg ha -1 equivalent to 0, 50, 75, 100, 125 and 150% of recommended N doses. Seeds were inoculated with Bradyrhizobium inoculum before sowing. Nitrogen application progressively and significantly increased the yield of soybean upto the N rate of 26.45 kg ha -1 where the highest seed yield of 6.85 g plant -1 was obtained. Nutrient uptake and protein content in seeds also increased with increasing levels of N (up to the same rate of 26.45 kg N ha -1 ). It is concluded that application of 25% higher N over BARC recommendation could give maximum seed yield, protein content and nutrient uptake by soybean seed.
