The recognition of highly valued soybean in India is well understood by its cultivation of 6 lakhs hectares during 1980-81 (Bhatnagar, 1980-81). Though Assam is famous as a rice growing area, the typical uplands are not properly utilized for rice because of partial to nonavailability of irrigation water. These areas are either partly used for raising rice seedlings or put to summer vegetables.
