and the plant free from an important obstacle in the 

 way of introduction to new regions. A crop of seed is 

 ensured wherever conditions are such as to allow the 

 plants to make the proper vegetative growth and reach 

 maturity. 



There are over 200 varieties of Soya bean, which 

 are distinguished according to the colour, size and shape 

 of the seed, and the time required for the plants to reach 

 maturity. This large number of varieties can be formed 

 into six groups yellow, greenish-yellow, black, brown, 

 green and white. 



The yellow variety has the largest giowth, and is rich 

 in oil (17 to 19 per cent.), albuminoids, carbohydrates, 

 and nitrogen. Under average conditions it grows from 

 3 to 5 feet, and requires from 120 to 150 days to mature 

 a crop of seed. The average yield should be 30 bushels 

 per acre (600 kilograms). Under no circumstancea 

 should this seed be planted more than 2 inches deep. 

 The crop can be readily harvested with machinery, and 

 is frequently gathered with a grain-binder. One of the 

 yellow varieties, the " Southern/' has given very good 

 results in Natal and in the Northern Transvaal. In 

 West Africa also progress has been made, and a larger 

 amount of oil has been obtained there than in Manchuria, 

 Japan, or the United States, and, just before the war, 

 this variety was being experimented with in East Africa 

 and the Sudan. 



The greenish-yellow, a medium late variety, is vigorous 

 but not coarse, growing 3 to 4 feet high with numerous 

 branches, none close to the ground. 



The green is grown extensively in N. China, and, 

 containing about 17 per cent, of oil, is considered to be one
