Soybean is second most important oil seed crop in India. Yellow seeded soybean was introduced in India in 1963–64. Over a period of three decades there has been an exponential increase in area and production of the crop. But the productivity is stagnant around 1 tonne/ha whereas the world average is 2240 kg/ha. In this article an attempt has been made to analyse various reasons for low productivity and some suggestions have been made to increase productivity.
