Grown in fertile soils with clean waters, Okcheon’s soybeans show
distinguished taste and quality.
Soybeans are widely cultivated as edible crops. The stem is 60-100cm in height and mostly
grows straight. The roots have many
bulbs. On the stems grow three
alternating leaves that are egg-shaped or oval with smooth edges.
The red or white blossoms bloom in July and August and the small
flower stalk from the bottom of the leaves bears raceme. The calyx is bell-shaped with the end
diverging into five tips. The corolla is
butterfly-shaped with 10 stamens.
The fruit is a legume and oval in shape with 1-7 seeds. When fully ripened, the end opens up to
scatter the seeds. The seeds are divided
into various sizes and shapes. The
colors of the seeds are yellow, black, light brown, and green.

Huabei region of China. In China, soybean has been cultivated
for more than 4,000 years as one of the five major grains. Historical records tell us that Korea
began cultivating soybeans from the early Age of Three Empires (early 1st
