The onion is a hardy cool-season biennial but usually grown as an annual crop. They come in a variety of shapes, sizes, and colors. Farmers will generally grow onions from seeds and transplant the seedlings. Onion sets are mainly used for seed production. Depending on the duration of the variety grown and climatic conditions, farmers can cultivate 3 cycles of onion per year.

The best soil for successful onion cultivation is deep, friable loam and alluvial soils with good drainage, moisture-holding capacity and sufficient organic matter. The optimum pH range, regardless of soil type, is 6.0 - 7.5, but onions can also be grown in mild alkaline soils. They require abundant sun and drainage. The onion plants grow well in raised beds or rows of mounded soils that are at least 10 cm high.
Onion is a temperate crop but can be grown under a wide range of climatic conditions such as temperate, tropical and subtropical climate. The best performance can be obtained in a mild weather without the extremes of cold and heat and excessive rainfall, however, onion can withstand freezing temperatures. It requires about 70% relative humidity for good growth. It can grow well in places where the average annual rainfall is 650-750 mm with good distribution during the monsoon period. Onion crops need lower temperature and shorter day light (photoperiod) for vegetative growth while during the bulb development and maturity stage it needs a higher temperature and longer day light.
