Shahidullah, M. | Rahman, M.A. | Karim, M.A.
An experiment was conducted with three soybean varieties, Bragg, Lee-74 and Improved Pelican; and four N-doses, 33.64, 44.86, 56.07 and 67.28 Kg N/ha, to study the effect of variety and nitrogen on the growth, yield and nutrient content of soybean. Improved Pelican produced significantly more branches and pods per plant and gave the highest seed yield. Oil, protein and carbohydrate contents were the maximum in the seeds of the varieties Bragg, Pelican and Lee-74 respectively. The highest seed yield was obtained by applying 56.07 Kg N/ha. The oil content increased with the increase in the amount of nitrogen. The highest protein and carbohydrate contents were recorded with the application of 44.86 kg N/ha
