Traditional Crispness & High Vigor: Vanda Inter Seeds Yard Long Bean OP (Red Seed)
Supply the fresh market with an absolute staple of Thai and Asian cuisine using the Vanda Inter Seeds Yard Long Bean OP – Red Seed. Known locally as “Thua Fak Yao,” this long, crisp bean is a foundational ingredient in iconic dishes such as Som Tam, Pad Prik King, and various fresh chili dips. The “Red Seed” (Melad See Daeng) strain is highly regarded by traditional farmers for its exceptional germination energy and robust early growth. As a stable Open Pollinated (OP) variety, it provides professional growers with a reliable, field-tested crop that thrives in intense tropical environments.
Robust Field Vigor and Continuous Harvesting: Growing yard long beans in the tropics requires genetics that can handle extreme heat and humidity without dropping their flowers. This Vanda OP variety is perfectly adapted to these conditions. It develops a vigorous, fast-climbing vine structure that quickly covers a trellis, ensuring maximum sunlight capture and airflow. Because of its strong root system and inherent tolerance to common soil-borne stressors, this variety ensures a long, highly profitable harvesting window, pushing out continuous flushes of long, uniform pods.
Key Characteristics:
- Authentic Flavor & Texture: Delivers a satisfying, crisp crunch and a mild, sweet interior that holds up perfectly to pounding in a mortar or high-heat wok cooking.
- High Seedling Vigor: The red seed trait is associated with fast, robust germination and rapid early vine establishment.
- Heavy Continuous Bearer: Highly prolific flowering leads to multiple dense pod clusters, maximizing yield per square meter.
- Stable OP Genetics: Reliable, field-tested Open Pollinated seeds that offer robust tropical adaptability and consistent crop uniformity.
Professional Planting & Care:
- Soil & Support: Yard long beans are vigorous climbers. Before planting, construct a sturdy overhead trellis, A-frame, or netting system (at least 2 meters high). This allows the long pods to hang straight down, keeping them unblemished and preventing soil-borne rot.
- Sowing & Spacing: Direct sow seeds into well-draining, highly fertile soil on raised beds. Plant 2–3 seeds per hole, roughly 2–3 cm deep. Space the planting holes 40–50 cm apart with 1 meter between rows. Thin to the two strongest vines per hole after 10 days.
- Watering & Nutrition: Maintain consistent moisture, particularly once flowering begins. Apply a balanced NPK fertilizer (15-15-15) during early vegetative growth. Once flowers appear, side-dress with a phosphorus and potassium-rich blend (such as 8-24-24) to maximize pod length, firmness, and continuous setting.
- Harvesting: Begin harvesting 50–55 days after sowing. Pick the beans while they are still smooth, crisp, and before the seeds inside begin to swell and bulge the pod. Regular harvesting (every 1-2 days) is crucial to encourage the plant to produce more flowers.
