LONG WHITE KOSHIKAYA

Stable "green" yield

Working with "Long White Koshigaya" from Sakata, you understand why Japanese breeding is considered the benchmark for professional vegetable growing. This is a bunching onion variety that proves its efficiency on an industrial scale. The main issue farmers usually have with bunching onions is unpredictable growth and lodging, but here the situation is different: the plant is strong and upright, which is critical for manual harvesting. You do not waste extra time on sorting — the leaves are uniform, dense, and have an excellent market appearance.

Agronomic nuances and protection

With a planting density of 6,000–8,000 thousand plants/ha, we get a well-balanced field. A yield exceeding 100 tons per hectare requires discipline from the operator regarding nutrition and irrigation. As a salad variety, the leaves must remain juicy and tender. Important note: although the variety is resilient, in conditions of high humidity, it is necessary to monitor crop health, especially considering the risks of fungal diseases (downy mildew). Timely preventive treatments allow the Sakata potential to be fully realized.

Practical operation insights

• Maturity: Up to 90 days is the "golden mean," allowing for scheduled conveyor supplies.
• Harvesting: Manual labor is justified by the leaf quality, which remains undamaged during careful cutting.
• Economy: High planting density provides maximum yield per square meter.

If you are looking for a variety that maintains market demand and delivers predictable results under intensive technology, "Long White Koshigaya" is a professional tool that requires nothing more than adherence to basic agronomic practices.
