Factors that affects bulb quality include;
1.Genetics (Variety Selection)
Variety: Some bulb onion varieties are naturally bred to be globe-shaped, Choosing high-quality seeds is the first step to achieving these traits.
Seed Quality: Certified seeds from reliable suppliers ensure strong genetic traits.
2. Nutritional Management
Nitrogen: Avoid excess nitrogen during bulbing as it may lead to flat bulbs.
Phosphorus and Potassium: These nutrients are essential for root development, bulb size, and overall strength. Potassium also enhances the bulb's color intensity and storage quality.
Sulfur: Sulfur-rich soil improves onion pungency and contributes to the strong flavor and firmness.
Micronutrients: Elements like zinc and boron promote proper cell division and development, ensuring a uniform globe shape.
4. Watering and Irrigation
Proper and consistent watering is key. Irregular watering can cause bulbs to crack or become uneven.
Avoid overwatering during the late stages of growth, as it may lead to soft bulbs.
5. Bulb Formation Practices
Spacing: Proper spacing (7-10) cm between plants) ensures each bulb has enough room to grow into a globe shape. Crowding can lead to smaller or irregularly shaped bulbs.
Trimming: Trimming seedlings during transplanting encourages stronger plants and uniform bulbs.
