Soybean occupies first position among the oil seed crops in terms of acreage and production in India. Besides contributing substantially to the edible oil needs of the country, it earns valuable foreign exchange by way of export of soy meal. Soybean has changed the economic status of the farmers who are growing soybean; still farmers are struggling with the problem of loss of seed quality of soybean. Good field emergence is being a problem due to one or other reasons. Soybean seed is very delicate in nature due to its structural limitations. Chemical composition high protein and high oil content also makes it vulnerable to biochemical degradation during maturity and storage. Maintaining the quality of seed produced during month of Oct-Nov up to the next sowing time in the month of June-July is a difficult task in tropical and subtropical countries like India. The climatic variability leading to delay in monsoon, drought spells of different duration at various growth stages, water logging conditions and above normal temperatures particularly at seed fill stage are the main reasons of low productivity of soybean in India. Poor germination potential of soybean seed and faster deterioration of its seed quality under ambient storage are major problem. In this article, intrinsic factors of soybean seed quality loss and practical approach to tackle the problems have been explained.
