Varieties Soybean:
Research on different aspects of Soybean has been conducted in different Institution under Bangladesh Coordinated Soybean Research Project (BCSRP) of the Bangladesh Agricultural Research Council (BARC). After a series of experiments on yield, maturity period, resistance to diseases, etc., two varieties has been found suitable and recommended for adoption in Bangladesh:
1. Bragg:
This kind of Soybean plant is medium in height. The flowers are white. Depending on different seasons it takes 3 - 4 months to mature. Three Soybean Crops may be raised in a year with this variety under favorable climate it may yield up to 27 mds per acre (25 quintals per hectare).
2. Davis:
This kind of Soybean plant is slightly more than that of Bragg. The flowers are white and the likes 110 - 120 days to mature. The numbers of pods per plant are more than those of Bragg. As a result, the yield is also higher. Under favorable climate conditions, its yield goes up to 29 mds per acre (27 quintals per hectare). The viability, germination capacity, resistance to diseases and pests of Davis type Soybean is higher than those of Bragg.
