The experiment was designed in 3 farmer’s fields, one farmer’s field is a replication with full set of varieties. The density was 35 plants/m2 in spring season and 30 plants/m2 in Summer-autumn season. Fertilizers application was of 30N - 60 P205 - 60 K20, and 800 kg of Song Gianh microbialorganic fertilizer. The results showed that, two soybean varieties ĐT51, ĐVN14 have similar growth-duration with local soybean variety in summer - autumn season (84 days), but in spring season, their growth-duration was 5-7 days longer than local variety. Variety NAS-S1 has 7 days shorther than local variety in growth-duration in summer - autumn season but 3 days longer than local check in spring season. The average yield of three varieties DVN14, DT51, NAS-S1 ranged from 44,0- 66,0-69,0% respectively higher than local check in Summer-autumn season, and 113 - 189 - 170% higher than local check in spring season.
