Seedling
7-10 daysCotyledons emerge and expand; first true leaves appear; plant is 2-4 inches tall
Keep soil evenly moist. Protect from birds and wire worms. Monitor for damping-off disease in wet conditions.
Vegetative
30-40 daysRapid leaf development, branching begins, plant height increases to 12-20 inches; root system deepens
Maintain consistent moisture. Apply nitrogen-fixing inoculant benefits begin to take effect. Monitor for early pest pressure (Japanese beetles, bean leaf beetles).
Flowering (R1-R2)
10-14 daysFirst flowers appear at leaf nodes; plant is 18-30 inches tall; begins reproductive phase
Critical water stage—maintain 1-1.5 inches per week. Avoid drought stress. Begin scouting for spider mites and aphids. Do not apply herbicides during flowering.
Pod Fill (R3-R5)
30-40 daysPods enlarge and fill with seeds; plant may reach full height (24-36 inches); lower leaves may yellow and drop
This is the most water-critical stage. Maintain consistent moisture. Monitor for pod diseases and mites. Avoid foliar pesticides 30+ days before harvest.
Maturity & Harvest
14-21 daysPods dry and brown; seeds inside are firm and white; plant senescence, leaves drop; pods rattle when shaken
Reduce irrigation. Harvest when moisture content reaches 12-15% for clean combining. Delay harvest to avoid pod shattering in dry conditions.

Common Pests
-
Handpick in early morning, use pheromone traps away from field, apply neem oil or spinosad if damage threshold reached
-
Scout regularly; threshold is 30% defoliation in vegetative stage. Use insecticidal soap or pyrethrin-based products
-
Increase irrigation to reduce stress, spray with miticide (sulfur, neem) in hot conditions; predatory mites help naturally
-
Monitor for buildup; spray neem oil or insecticidal soap; encourage natural predators like ladybugs
-
Use resistant varieties in rotation, practice crop rotation (3+ years away from soybeans), manage with resistant cover crops
Uses
Tofu & Soy Products
CulinaryWhite soybeans are the preferred variety for producing tofu, soy milk, soy yogurt, and tempeh due to their clean appearance and neutral flavor profile. The high protein content (36-40%) makes them ideal for protein-rich food production. [source]
Edamame (young pod harvest)
CulinaryYoung, tender pods harvested at the immature stage and blanched provide a nutritious snack or appetizer rich in complete protein and fiber. Popular in Asian cuisine and increasingly common in Western markets. [source]
Oil & Meal Production
HouseholdMature seeds contain 18-22% oil used in cooking, biodiesel, and industrial applications. The protein-rich meal remaining after oil extraction is used as livestock feed and fertilizer. [source]
Isoflavone Source
MedicinalWhite soybeans contain isoflavones (genistein, daidzein) which may support bone health, hormone balance, and overall wellness. Often consumed as whole foods or supplements. [source]
Nitrogen Fixation & Soil Health
HouseholdLike all soybeans, Asgrow White forms symbiotic relationships with nitrogen-fixing bacteria, reducing the need for synthetic nitrogen fertilizers and improving soil fertility for subsequent crops. [source]

Harvest Tips
Wait until pods are brown and dry, and seeds rattle inside (moisture 12-15%). Cut stalks close to the ground with a mower-conditioner or pull plants by hand. Dry harvested plants to 10-11% moisture before combining or threshing. For edamame harvest, pick pods when green and tender (before full maturity) and blanch immediately. Avoid harvesting when wet to prevent shattering.
Fun Facts
- 🌱 Asgrow is a division of Monsanto (now Bayer) with a century-long history of soybean breeding; Asgrow varieties are trusted staples in commercial agriculture across North America.
- 🌱 White soybeans are visually distinct and more marketable than yellow varieties, commanding premium prices in specialty food markets for tofu and soy milk production.
- 🌱 Soybeans can convert atmospheric nitrogen into usable soil nitrogen through their relationship with Bradyrhizobium bacteria—one plant can fix up to 15 pounds of nitrogen per acre in a season, reducing fertilizer dependency.
