Abstract

Experimental study of the effect of some technical measures on the growth and productivity of DT51 soybean variety in Bao Yen district, Lao Cai province. The experiment was conducted during the spring season from February to June 2018. The experiment was arranged in the style of large and small cells (Spit-Plot design) including 9 formulas, 3 replicates. The results of the study showed that the planting density and the amount of nitrogen fertilizing affected the height of plants, number of branches of level 1, pests, the constituent factors of productivity and yield of DT 51 soybean seed. Tree height ranges from 54.17 - 70.77 cm, the number of level 1 branches ranges from 1.53 - 3.33 branches. Theoretical productivity ranges from 25.69 - 40.88 quintals/ha. Actual net yield ranges from 15.70 - 28.26 quintals/ha, of which the formula P2M3 and P2M2 have the highest net yield of 25.73 - 28.26 quintals/ha. Economic efficiency in the formulas ranges from 8,554,000 - 39,873,000 VND/ha. In particular, the formula P2M2 has the highest net profit of 39,873,000 VND/ha, followed by the P2M3 formula of 30,998,000 VND/ha.
