Conditions for Onion Farming Onion farming requires specific conditions for optimal growth and yield. Proper attention to these factors ensures healthy plant development, bulb formation, and overall success in your onion farming.
1. Climate: Onions thrive in cool to mild climates with moderate temperatures. The ideal temperature range for onion growth is around 13°C to 24°C. Avoid extreme temperature fluctuations, as they can lead to poor bulb development.
2. Soil: Choose well-drained soils with good water-holding capacity, preferably sandy loam to clay loam. The soil pH should be slightly acidic to neutral, ideally ranging from 6.0 to 7.5. Ensure proper soil preparation, including loosening, leveling, and incorporation of organic matter.
3. Irrigation: Onions require consistent moisture throughout their growth cycle, especially during bulb formation. Drip irrigation is recommended to provide targeted and efficient watering while minimizing water contact with foliage.
4. Sunlight: Onions thrive in full sunlight. Ensure your onion field receives at least 12 to 14 hours of direct sunlight daily.
5. Spacing: Proper plant spacing is crucial for healthy bulb development and disease prevention. Generally, onions should be spaced 10 to 15 cm apart within rows, and rows should be spaced 20 to 30 cm apart.
Onions Nursery bed preparation Onions are planted on a raised seedbed for germination and later transplanted into the field. Therefore, preparing the seedbed two to three weeks before sowing is encouraged. To make your seedbed, proceed as follows; Prepare raised seedbeds of 1.2m wide with a length of your choice. Add two 20 liters per square of organic fertilizer, mix it with the soil, and rake it evenly. Irrigate the raised seedbed one day before sowing seeds. Make evenly spread rows of 10-15cm from row to row.
Field Preparation for Onion Farming Plow the land one month before transplanting the onion seedlings. Rake the soil to fine particles for two weeks before transplanting the onions. Next, Incorporate 20 -25 tonnes per hectare of ripe animal manure (Poultry or cow dung) into the field. This makes the soil rigid and increases moisture retention for an extended period. Mix the organic fertilizer well with the ground, then prepare the furrows you like. Add the organic manure to every hole during transplanting instead of mixing it with the soil.
Onion Seedlings Transplanting After six weeks after germination, the seedling should be ready for transplanting. The seedlings should have attained a 12 to 15-cm height by this time. To avoid damaging the roots, thoroughly water the seedbed a day before transplanting. Use a shovel to uproot the seedlings from the seedbed, and remember to prune the seedling leaves and roots to enhance water retention. Plant the seedlings in rows with a 30cm space between rows and 8 to 12cm from one seedling to the other. Onions grown in this position take the shortest time possible to mature early, and the number of onions per area is vast.
How to Plant: To get the best results with onions you need to start them in a Nursery. Here is how to do this;
Make a raised nursery bed 1 metre wide and any desired length. Apply well decomposed manure at a rate of 15kg per square metre.
Mix and Apply DAP fertilizer at a rate of 20 grams per metre square
Make shallow furrows 15 cm apart.
Mix the seeds with dry ash, sand or soil at a ratio of 1:3 to help spread the small seeds.
Plant the seeds and cover lightly with soil and apply mulches ( Grass or Polythene cover spread over the soil on the nursery bed)
After planting irrigate the nursery bed liberally for the first 10 days and continue watering regularly.
Germination of seeds will take about 7-10 days after which the mulches are removed and used to make a shade above the tender plants which have not fully developed.
Transplanting of the seedlings takes place 6 weeks after planting seeds in the nursery. Transplant when the seedlings have pencil thick base and a height of approximately 15cm.
Seedlings should have 3 to 5 well formed leaves at transplanting time. Two weeks before transplanting reduce the shade to improve seedling survival rate in the field. It takes about 4 months for onions to mature
