Analysis on plant of vegetable soybean variety 292 were carrled out at two compound leaves,flower-beginning, pod-setting and pod-picking stages, respectively. The results showed that: (1) The dry matter accumulated the most quickly durhg the period from pod-setting to pod-picking and accounted for 43.98% of the total accumulated amoun. The daily gain was the most quickly from flower-beginning to pod setting stages. (2) The content of nitrogen and phosphorous were the highest in leaves at the stage fron、seedling to flower-beginning. The content of potassium was the highest in stems. The content of nitrogen, phosphorous and potassium were the highest in pods.(3) The content of nitrogen, phos-phorous and potassium varied greatly with different organs. The content of nitrogen was leaf flower and podstem; The content of phosphorous was flower and podleaf. stem. The content of potassium was stem leaf flower and pod. (4) To produce 100kg fresh pods,1.73kg nitrogen,0.19kg P2O5 and 0.94kg K2O were needed, with the ratio of N:P:K 1:0.11:0.54
