Onion farming can be a profitable venture for farmers. With the ongoing onion season, many farmers are cultivating this essential crop on a large scale. Proper use of fertilizers at the right time can significantly improve onion size and yield. By adopting specific techniques, farmers can grow onions weighing up to half a kilogram.

Best Ways to Enhance Onion Size and Yield:

1. Proper Use of Fertilizers:

Nitrogen and phosphorus are crucial for the healthy growth of onions, as they support root and bulb development. Farmers should use the following fertilizers:

• For nitrogen supply: Use ammonium sulfate or ammonium nitrate.
• For phosphorus and potash: These nutrients strengthen onion bulbs and boost production.
• Apply one cup of ammonium sulfate or ammonium nitrate per 20 feet of row.

2. Maintaining the Right Water Levels and Irrigation Techniques:

Balanced irrigation is essential for proper onion growth.

• Keep the soil consistently moist to ensure healthy development.
• Avoid overwatering, as it can lead to root rot and crop damage.
• The drip irrigation method is highly effective for onion farming, maintaining optimal moisture levels.

3. Effective Weed Control:

• Weeds can harm onion crops by absorbing essential nutrients.
• They compete with onions for water and fertilizers, reducing yield.
• Regular weeding and hoeing help maintain soil health and ensure better crop growth.

4. Urea Application After 30 Days:

When the onion crop reaches 30 days, spraying urea and compost fertilizer can significantly boost yield.

• Apply 3 to 4 tons of compost per acre along with urea to enhance onion quality and productivity.
• This practice increases farmers’ profits by improving crop health.

5. Regular Monitoring and Proper Crop Care:

• If onion plants turn yellow or stop growing, immediate organic or chemical treatments should be applied.
• Soil testing helps determine the right fertilizers needed for better crop yield.

By implementing advanced agricultural techniques such as proper fertilization, balanced irrigation, and effective weed control, farmers can maximize their profits from onion farming. High-quality, large onions always have strong market demand, allowing farmers to secure better prices. With the right steps at the right time, onion farming can become a highly profitable venture.
