Good Agricultural practices of Onion Crop

Good Agricultural practices of Onion Crop

Onion is an important commercial crop grown in India. It is used both as vegetable and spice in different crop stages.

Soil and climatic requirements:

Well-drained sandy loam soil is best suited. The optimum pH range would be 6.0 – 7.5. Water logging and alkaline soils adversely affect the growth & development of plant & bulb.  Onion is a cool season crop. It is grown during winter and harvested before the real hot season begins. But it grows well in mild season without extremes of heat and cold.

Varieties: At the following link the seed varieties can be viewed. Few of them are Nasik Red, Prerana,XP Red onion, Gulmohar, Prema Onion, Marshal onion ,..etc.
