Onion cultivation in India is widespread on a large scale, primarily during the Kharif season.

Farmers often face the challenge of protecting their crops from pests and diseases, and selecting the right fertilizers.

Farmers can use organic fertilizers like cow dung manure for better onion yields.

Apply cow dung manure at a rate of 20 to 24 tons per hectare before planting onions, about 10-12 days prior.

For nitrogen needs in the field, farmers can use ammonium sulfate or single super phosphate.

During the Kharif season, onions require irrigation approximately 10 to 12 times.

The Rabi season, irrigation for onions should commence about 15-18 days before planting.

This results in thicker onion skins and better yields. By using these fertilizers, farmers can achieve abundant production and good profits.
