Onion Seed Production Technique - introduction

India is the second largest producer of onions globally, producing 19.4 million tons annually from 1.2 million hectares. Onion seed production in India requires 7,000 tons per year. Environmental factors like temperature, rainfall, soil conditions, and beneficial insect populations influence onion seed production. The two main methods of onion seed production are bulb-to-seed, which involves growing bulbs that are then planted the next season to produce seeds, and seed-to-seed, where seedlings are transplanted and allowed to flower in the same field without harvesting bulbs. Proper nutrition, weed management, pest and disease control are required for high quality mother bulb and seed production.
