It is an F1 hybrid white onion developed for uniform bulb production.
The variety is characterised by:
AgriTech lists a potential bulb weight of approximately:
350–400 g
under suitable commercial growing conditions.
Actual bulb size in home gardens may be smaller or larger depending on:
Super White F1 is suitable for gardeners wanting a distinctive white onion for both fresh use and cooking.

G-11 Grow Bag – 11 × 10 inch 🔗
Suitable for growing a small number of Super White F1 onion plants with proper spacing.
G-12 Grow Bag – 12 × 12 inch 🔗
Provides sufficient depth and soil volume for several plants.
G-24 Grow Bag – 24 × 12 inch 🔗
Recommended for growing a larger group of Super White F1 onions.
Because onions have relatively shallow root systems, the wide growing surface of G-24 is especially useful for group planting while maintaining adequate bulb spacing.
Use fertile, loose and well-drained loamy soil rich in organic matter.
A practical GREEN GARDENS mix can be:
50% Bhalu Mitti (Sandy Soil) + 50% Vermicompost 🔗
Super White F1 Onion prefers:
An approximate soil pH of:
6.0–7.0
is suitable.
Avoid:
Loose soil is particularly important for development of large, uniform bulbs.
For best control, start Super White F1 Onion seeds in:
Sow approximately:
0.5 cm deep
or around:
¼ inch deep
Cover lightly with fine soil.
Water gently after sowing.
Keep the growing medium consistently moist during germination.
Seeds generally germinate within:
7–12 days
under suitable conditions.
Maintain mild temperatures and even moisture.
Avoid allowing the nursery medium to:
Healthy early establishment is important for later bulb development.
After germination, provide:
Allow seedlings to develop steadily before transplanting.
Transplant seedlings after approximately:
35–45 days
or when plants are well established and around:
12–15 cm tall
depending on growing conditions.
Handle roots carefully.
Avoid burying seedlings excessively deeply.
The bulb should later develop close to the soil surface.
Provide:
6–8 hours of direct sunlight daily
Full sunlight supports:
Avoid deep shade.
For large bulb production, maintain approximately:
10–15 cm between plants
Where rows are used, maintain approximately:
25–30 cm between rows
Adequate spacing is especially important for a large-bulb hybrid such as Super White F1.
Crowded plants generally produce smaller bulbs.
Maintain steady moisture during:
Water when the upper soil begins to dry.
Avoid:
As bulbs approach maturity, gradually reduce unnecessary irrigation.
Before transplanting, incorporate GREEN GARDENS Vermicompost 🔗.
Onions benefit from good fertility during early growth.
Balanced nutrition supports:
Avoid excessive nitrogen during later bulb development.
Too much nitrogen can keep plants overly vegetative and delay maturity.
Keep the growing area free from aggressive weeds.
Onions have relatively shallow roots and compete poorly with weeds.
Remove weeds gently to avoid damaging:
Avoid deep hoeing immediately around mature plants.
Bulbs gradually enlarge as plants mature.
Do not repeatedly cover the developing bulb with heavy soil.
Allow bulbs to develop naturally close to the soil surface.
Potential bulb size is strongly influenced by:
Under suitable commercial conditions, Super White F1 is listed as capable of producing bulbs around 350–400 g.
Apply a light mulch where required.
Mulching can help:
Keep thick mulch away from the bulb neck.
Inspect plants regularly for:
Maintain:
Do not assume F1 hybrid status means immunity to pests or diseases.
Plants may be harvested young for:
Green onion-style use
if desired.
However, for maximum Super White bulb development, leave selected plants undisturbed until full maturity.
The existing GREEN GARDENS crop guidance places maturity at approximately:
100–120 days after transplanting
under suitable conditions.
Harvest when:
Stop excessive irrigation near maturity.
Lift bulbs carefully to prevent cuts and bruising.
After harvesting, cure bulbs in a:
Dry, shaded and well-ventilated location
Allow:
After curing:
Proper curing is essential for maintaining storage quality.
