100 days, indeterminate — The plants grow thirty six to thirty eight inches in height, have white flowers, and produce medium, round, yellow seeds with brown eyes that contain about 21% oil and 39% protein.
The parent stock was USDA accession number PI 548411. It was originally collected in Northeast China in 1920 as FC 03654. It was further developed and released as 'Seneca' in 1949 by R.G. Wiggans of Cornell University, Ithaca, New York. Each packet contains 25 to 30 seeds.
Sow seeds about one inch deep, three to four inches apart. Although you can plant in rows, they can be planted densely and allowed to form a canopy. This will help control weed growth. Soybeans are tolerant of drought and poor soil since they fix nitrogen. They will, however, benefit from fertile soil.
Soybean flowers are perfect (self-fertile) and cross pollination is almost non-existent, making saving seed easy. Allow pods to fully develop and dry on the plants.
