Abstract
Investigations have been carried out to determine the difference between upland culture and drained paddy field culture on the yield, weight of 100 seeds, ratio of seed coat, and chemical omposition (protein, oil, carbohydrate, ash, potassium, phosphorus, magnesium, calcium, ion, manganese, and fatty acids) of soybean seeds of 5 varieties. The drained paddy field culture, as compared with the upland culture, gave significantly heavy weight of 100 seeds and high manganese content on dry matter basis and in ash. Among the varieties, significant differences were observed in weight of 100 seeds, oil, calbohydrate, magnesium and calcium content on dry matter basis, phosphorus, magnesium, calcium, and manganese content in ash, and palmitic acid and linolenic acid ratio in total fatty acids.
