Explanation:

Production of Soyabean in India at the present time is restricted mainly to Madhya Pradesh, Uttar Pradesh Maharashtra and Gujarat. Soyabean is used for making high protein food for children. Soyabean grows well in warm and moist climate. A temperature of 26.5 to 30°C appears to be the optimum for most of the varieties. Soil temperatures of 15.5°C or above favour rapid germination and vigorous seedling growth. The minimum temperature for effective growth is about 10°C. Well drained and fertile loam soils with a pH between 6.0 and 7.5 are most suitable for the cultivation of soybean.
