Climatic requirements for soybean cultivation Soybean is a warm season crop. Its cultivation is now extended to subtropics and temperate climates. It can grow well in areas receiving annual rainfall from 600 to 1000 mm. Soil temperature of 15.5°C or above favour rapid germination and vigorous seedling growth. The minimum temperature for effective growth is about 10°C. Lower temperature delays the flowering. Temperature of 26.5 to 30°C appears to be optimum for most of the varieties.
