Introduction to bulb onion farming11:26
Discover how to grow bulb onions from seed to bulb, including seed selection, nursery, transplanting, field management, and pest prevention. Learn the harvest, storage, marketing, and economics for profitability.
Growing Regions and Seed Selection12:04
Identify warm regions at low to mid altitude for onion production and select seed wisely, favoring hybrids for higher yields, longer shelf life, and disease resistance with uniform bulbs.
Nursery Establishment PART 111:56
Establish a hybrid raised and sunken onion nursery bed, 1 m by 8 m, with well-decomposed compost manure, water well, and sow seeds along 6-inch lines about 1 inch deep.
Nursery Establishment PART 214:00
Master nursery establishment for onions with sparing seed placement, flat sunken beds, mulching, and weekly spray cycles using imidacloprid and carbendazim to prevent pests and diseases.
Watering and Land Preparation14:07
Evaluate water sources and quality to ensure irrigation from planting to harvest. Prepare land with bed or drip irrigation and perform soil analysis and history checks to guide nutrient management.

Transplanting PART 110:33
Transplant seedlings from the nursery to the field with irrigation and loose soil to minimize root shock, using drip beds and 15 cm plant spacing to yield 120 g bulbs.
Transplanting PART 27:52
Transplanting part 2 covers field transplanting of nursery onion seedlings, labor needs, spacing, and timing, with drip irrigation guidance to achieve marketable medium-sized bulbs.
Starting Stage13:53
Master the starting stage of onion farming: plan fertilization from soil analysis, apply starter nutrients, and implement weed, pests, and disease management, using stickers to improve foliar sprays.
Vegetative Stage11:39
Strengthen onion growth in the vegetative stage (weeks 3 to 6) by applying nitrogen-rich nutrition and foliar feeds, while implementing a weekly spray program to keep foliage green and disease-free.
Bulb Initiation PART 18:52
Explore bulb initiation for onions, emphasizing potassium-driven bulb formation, foliar nutrition, and pest and disease considerations, plus precise spacing with drip lines, 0.5 m paths, and 1 m beds.
Bulb Initiation PART 211:26
Learn the bulb initiation and development stages of onion farming, from transplanting to bulb enlargement, with emphasis on potassium nutrition, soil analysis, and integrated pest and disease management.

Bulb Development8:56
Foster rapid onion growth and color during bulb development with potassium-rich fertilisers and micronutrients, and apply pest and disease protection on a 7–10 day cycle to maintain bulb quality.
Bulb Maturity7:52
Bulb maturity is when onions reach full bulb size around weeks 10–12 and begin curing as leaves brown. Maintain potassium-focused nutrition, but avoid sprays as disease control wanes.
Curing onions7:33
Learn the onion curing process to dry and seal bulbs for long shelf life, including when to cut leaves, post-harvest handling, and differences between hybrid and open-pollinated varieties.
Harvesting onions13:47
Harvest onions when leaves brown and bulb matures 9–12 weeks, then cure the top. Store in ventilated, raised space with nets to prevent moisture and rot up to six months.
Finding Market9:54
Conduct market research to identify onion demand, seasonality, pricing, and return on investment, then target channels like institutions, grocery stores, and hotels, using social media and strong customer service.

Economics9:59
Explore the economics of onion farming, detailing input and output costs, yield potential per acre, price ranges, and how management and labor influence profitability across two seasons.
Crop Rotation8:03
Use crop rotation and maize windbreaks to protect onions from thrips and diseases, rotating crops to different families each season to rejuvenate the soil.
Farmer Interview7:42
Explore a farmer's journey in general agriculture and onion production, highlighting self-employment, irrigation and water management, fertilizer lessons, and pests and diseases toward seed-to-bulb profits.
