| Abstract: | A pot experiment has been conducted to study on the yield of 3 soybean cultivars at 3 nitrogen rates. The results show that the accumulation of dry matter and seed yields all increase with nitrogen rates,but that the weight of 100 seeds increase little except that of Dongnong 42.$$$$ |
