According to agricultural scientists, onions can be cultivated in different types of soil. But, excellent yield is obtained only in soils like clay, sand, loamy, gar and brown soil. To get high yield in onion cultivation, there should be good drainage facilities in the field.
To prepare for the cultivation , first plowing of the land should be done three to four times. Also, add rotten manure to increase the amount of organic matter in the soil. After this, divide the field into small plots. Planting should be done on a 1.2 meter wide strip at a height of 15 cm from the land surface.
Onion crop requires a large amount of nutrients. Manure and fertilizer should be used in onion crops on the basis of soil test. Rotten cow dung manure should be used in the field at the rate of 20-25 tonnes per hectare from one-two months before planting.
