How to Grow Harosoy Soybean
Harosoy Soybean
Glycine max 'Harosoy'
vegetableHarosoy is a widely-adapted soybean cultivar developed in Canada, known for its reliability and consistent yields in cooler climates. It produces bushy plants with small black seeds ideal for both food and feed purposes. This variety has been a standard in northern soybean production for decades due to its excellent cold tolerance and disease resistance.

Germination & Seedling
7-10 daysSeeds emerge as small seedlings with cotyledons (seed leaves) visible. Plant develops first true leaves within 7-10 days.
Ensure consistent soil moisture (not soggy). Thin seedlings if direct seeding. Protect from heavy rain that could cause damping off.
Vegetative Growth
30-40 daysPlant develops compound leaves and grows taller, forming the main stem and branching structure. Height reaches 18-30 inches.
Monitor for pest damage. Apply pre-emergence herbicides if weeds are a concern. No major nutrient input needed if soil is adequate.
Flowering
20-30 daysSmall white or pale purple flowers appear in leaf axils. Flowering typically begins at V5-V6 stage (5-6 trifoliate leaves).
Ensure consistent watering during this critical stage. Avoid drought stress. This stage is crucial for pod set and final yield.
Pod Development & Filling
25-35 daysFlowers transition to small green pods. Pods develop seeds inside and gradually fill out. Pods turn from green to yellowish-brown.
Maintain even moisture. Monitor for pod-damaging insects. Do not allow drought stress during this phase.
Maturity & Harvest
10-14 daysPods and plant material turn completely brown and dry. Seeds rattle inside pods when shaken. Plant is ready for harvest when pods are brittle.
Allow to fully mature for best seed quality. Harvest when moisture content is around 12-15% for long-term storage.

Common Pests
-
Hand-pick in early morning, use row covers during vulnerable stages, or apply insecticidal soap if populations are high.
-
Monitor for webbing and leaf damage. Use Bt (Bacillus thuringiensis) spray if threshold levels are exceeded.
-
Plant resistant varieties, rotate crops away from soybeans for 2-3 years, avoid contaminated equipment.
-
Increase humidity, spray with water, apply miticide if severe infestations develop.
-
Monitor populations, encourage beneficial insects, use insecticidal soap or neem oil for heavy infestations.
Uses
Edamame and Bean Products

Phytoestrogen Source
MedicinalSoybeans contain isoflavones, phytoestrogens studied for their potential health benefits in managing menopause symptoms and bone health. [source]
Nitrogen Fixation and Soil Improvement
HouseholdAs a legume, Harosoy forms symbiotic relationships with nitrogen-fixing bacteria, improving soil fertility and reducing the need for synthetic fertilizers in crop rotation systems. [source]

Harvest Tips
Harvest when pods are fully mature and brittle (approximately 110 days from planting). The pods should rattle when shaken. Cut or pull plants and dry thoroughly before threshing. For dried beans, allow plants to dry in the field if weather permits, then combine or thresh by hand. Store dried seeds in cool, dry conditions (40-50°F, 10-15% moisture).
Fun Facts
- 🌱 Harosoy was developed at the University of Guelph in Ontario, Canada, specifically to thrive in short-season northern climates and has been a staple in Canadian agriculture since the 1950s.
- 🌱 The name 'Harosoy' combines 'Har' (from the University of Guelph's location in southern Ontario) and 'osoy' (a reference to another parent cultivar), representing a true Canadian heritage variety.
- 🌱 Harosoy soybeans can convert atmospheric nitrogen into usable plant nutrients through root nodules containing Rhizobium bacteria, making them excellent for sustainable agriculture and crop rotation practices.
