Vegetable soybean DT08 were recognized as a trial production for the Red River Delta by Ministry of Agriculture and Rural Development in 2011. To contribute to extending the area, increasing productivity and economic efficiency of the production of DT08, researches into technical processes of seed production and intensive cultivation of vegetable soybean DT08 were carried out. Results of researching seed production technique: the sowing time in spring from February 25 to March 7, in summer from June 5 to June 15, in winter from September 5 to September 15; the plant density of 25-30 plants/m2 with 1 plant/hole; fertilizers in spring and winter crop of 2 tons of microbial organic fertilizer + 50N + 100P2O5 + 90K2O, and in summer crop of 2 tons of microbial organic fertilizer + 40N + 100P2O5 + 90K2O. Results of researching fresh pod production technique: the sowing time as the seed production technique’s; the plant density of 30-35 plants/m2 in spring and winter, and 25-30 plants/m2 in summer with 2 plants/hole; fertilizers in spring and winter crop of 2 tons of microbial organic fertilizer + 50N + 100P2O5 + 90K2O, and in summer crop of 2 tons of microbial organic fertilizer + 40N + 100P2O5 + 90K2O.
