Ideal Location Agro Climatic Condition for Onion Farming
Generally, you can grow onion crops in different types of climatic conditions. However, it doesn’t prefer a mild climate. Additionally, extremes of heat, cold, and rainfall are not suitable for growing onions. Onion grows well in the optimum temperature range of 14°C to 16°C for 10 hours a day with 70% humidity is best for getting a good yield.
The rainfall requirement is 750 to 1000 mm/year. In addition, it requires bright sunny weather during the bulb development stage, therefore, grows well in the Rabi season.
Ideal Soil Condition for Onion Farming
Basically, you can grow onions in the alluvial, loamy medium type of soil. In addition to this, onion prefers well-drained loose, and friable soil. Heavy clay, marshy and alkaline soils are not suitable. Provide an optimum pH range between 5.8 and 6.5.

7 Basic Steps of Onion Farming
1. Raising Seedlings
You can raise onion seedlings on the nursery bed. Here, you can apply a seed rate of 5 to 6 kg per hectare. First, sow the seeds crosswise in rows. Then cover the seeds with a thin layer of soil. Then irrigate the beds at 3 to 4 days intervals and later on at 8 to 10 days intervals. Seedlings become ready for transplanting within 45 to 60 days when they attain a height of 10 to 15 cm.
You can grow onions at any time during the year. Plant the seedlings at a spacing of 10 cm apart on both sides of the ridges. However, you can also apply the flatbed method for transplantation.
Apply 25 to 30 cartloads of rotten FYM or compost at the time of soil preparation per hectare. For the onion, you must apply 50 kg N, 25 kg P^Os & 25 kg of Potash, as a usual method.
The water requirement of the crop at the Initial growth period is less. However, you must stop irrigation 15-20 days before attaining maturity for improving the keeping quality of bulbs. Frequent irrigation delays maturity. In the Kharif season, depending upon the rains and time of planting 6-10 irrigations are enough. In rabi, 10-15 irrigations are given at bulb formation, irrigation is necessary and moisture stress at this stage results in low yield.
5. Plant Protection
You must keep your onion farm weed-free. If you can’t control the weeds in the early stage but remove, them, later on, will injure the onion bulbs and the out-turn will be poor. 2-3 hoeing and weedings are enough for the crop. After 2 to 3 irrigations, earth up the poor plants.
6. Harvesting & Yield
Harvest the onion bulbs at the right stage of maturity. It is important in deciding the storage life of the onion as you can store the bulbs may for about six months. The onion bulbs, reach maturity when the plants cease to produce new leaves and roots. In onion, neck fall is an indication of maturity. However, the time of harvesting depends on several factors like planting season, cultivar, market price, and condition of the crop.
In the rabi season, the yield of onion is around 25-30 tons per hectare. However, in the Kharif season, it is comparatively low. You can expect 150 to 250 quintals of yield/ha
After harvesting, keep the bulbs in an open space for 3 to 4 days under the sun for initial drying. Then sort out the diseased, rotten, and damaged bulbs. Finally, store the bulbs in a cool, dry, and ventilated store. Use several compartments to avoid heaping bulbs.
During storage, inspect the bulbs regularly and remove the rotten bulbs. However, you can expect a storage loss of about 13 to 16% due to rotting and drying. You can store onion in cold storage at 10C to 20C temperature for a 7 to 8-month period. In the case of large-scale onion farming, you must have an arrangement for proper storage of the bulbs.
