A quick-maturing bunching onion

• A leaf bunching onion, ( A. cepa x A. fistulosum)
• A fast-germinating, vigorous variety with early maturity
• Tall, erect blue-green foliage
• White to light green shank
• High percentage harvestability with good holding capacity
• May form slight bulbs at full maturity

Climatic Requirements:

Soil temperatures for germination:
minimum: 10°C
optimum: 24°C
maximum: 35°C

Air temperatures for plant growth:
minimum: 12°C
optimum: 24°C

Soil Requirements:

Sandy loam to loam soils with good drainage characteristics. Well drained and light textured soils produce clean and well presented end product. Avoid soils with < pH 6 - nutrient uptake is affected at these pH levels. Spring onions in general are sensitive to saline soils.

Plant Spacing:

Optimal plant population is 850,000 - 1,000,000 plants/ha. Allow for in-row spacing of 20 - 40 mm between plants in the row. Inter-row spacing of 450 - 500 mm between rows. For best results spring onions must be produced on raised beds.

Nutrient Guidelines:

N required / ton spring onions produced: 3.9 kg / ton product.
P required / ton spring onions produced: 0.7 kg / ton product.
K required / ton spring onions produced: 4.1 kg / ton product.

Apply Ca as CaNO3 top-dressing during the initial growth of young plants. Apply micro nutrients as foliar feed or as fertigation to plants. Do not over apply N as this may lead to quality problems with the end product.

Irrigation Guidelines:

Keep soils moist, avoiding crust forming after planting to aid seedling emergence. Bunching onions have shallow root systems - frequent irrigation if essential for the crop. Water required from planting to emergence : 15 - 20 mm / week. Water required from emergence to seedling establishment : 20 - 25 mm / week. Water required from seedling establishment to maturity : 25 - 35 mm / week.

Weed Control:

Bunching onions compete poorly against weeds in field as they take long to canopy. Early field cultivation will kill off most weeds easing pressure on the growing crop. Mechanical cleaning of fields is not advisable as this will cause damage to plants.
