Necessity of the study Soybean or soya bean Glycine max L. Merrill belongs to the legume family Fabaceae order Fabales. Soybean is one of the important crops of high economic value with multiple uses providing human feed being a source of raw materials for livestock food industry medicibe cosmetics. In Vietnam soybean is a long-standing crop having an important position in agricultural production and considered as a high economic efficiency crop in the strategy of crop restructure increasing the value of agricultural products. With short growth duration soybean can be cultivated in many crop seasons during the year being ideal in crop rotation intercropping increasing of crop seasons and overlapping crop. Soybean production helps to increase land use coefficient create jobs and increase income for farmers. The soybean planting area in Winter - Spring 2019 of Hanoi reached thousand hectares over thousand hectares planted for the whole year accounting for the yield was tons ha the output reached thousand tons out of thousand tons year accounting for . Soybean has become the main crop occupying an important position in the Winter crop .
