ABSTRACT
Several exotic varieties of soybean grown in India give very high yield but poor quality of seed. Production of poor quality seeds, rapid loss of viability during storage, and poor and erratic field stand of the crop are the major problems in soybean cultivation in India. A series of experiments therefore were conducted in the field, laboratory and phytotron to find out the reasons for poor quality and storability of soybean seeds. Experiences of the Sri Lankan Soybean Development Program illustrate the opportunities and problems associated with a broad-based national program of crop production, marketing, processing, and utilization. Being of short duration and having rather wide adaptability, soybean is grown primarily as a secondary crop after rice in double and multiple cropping systems or as an intercrop in Indonesia. Soybean is threatened by several injurious pests and diseases. About 208 species of insects, 7 species of weeds and 9 different kinds of diseases have been found associated with soybean.
