Research for constructing intentive technique process of soybean variety DT2008 in son la province
Soybean variety DT2008 created by Agricultural Genetics Institute has high yield of 2.5-4.0 tons/ha (24.3% higher than DT84 control variety in National Variety Testing), high resistance to diseases and tolerance to drought. With the aim of expanding the area of DT2008 in Son La province, Agricultural Genetics Institute carried out the experiments of intentive techniques of DT2008 in spring and summer-autumn in Son La 2014. The results showed that the intentive technique processes appropriate to DT2008 in Son La province included the sowing date of 10th -20th March, the fertilizers per ha of 0.8 tons of microbio-fertilizer + 40 N + 90 P2O5 + 70 K2O, and the density of 30-35 plants/m2 in spring season; and in summer-autumn season, the sowing date of 20th -30th July, the fertilizers per ha of 0.8 tons of microbio-fertilizer + 30 N + 90 P2O5 + 60 K2O, and the density of 35 plants/m2 .
