Organic Onion (Step 1)

Introduction

  • India is the second largest onion growing country in the world. Indian onions are famous for their pungency and are available round the year.
  • Indian onions have two crop cycles, first harvesting starts in November to January and the second harvesting from January to May.

Climate

  • Onion is a cool-season crop, but it can also be grown in the Kharif (monsoon) season.
  • A temperature of approximately 21°C is considered suitable for the onion crop before bulb formation.
  • When the scale bulbs (storage bulbs) are developing, a temperature between 15°C and 25°C is ideal.

Soil

  • Onion can be grown in all types of soils such as sandy loam, clay loam, silt loam and heavy soils. However, the best soil for successful onion cultivation is deep, friable loam and alluvial soils with good drainage, moisture holding capacity and sufficient organic matter.
  • In heavy soils, the bulbs produced may be deformed. Onion crop can be grown successfully on heavy soil with application of organic manure prior to planting and preparation of the field for onion cultivation should be very good.
  • The optimum pH range is 6.0 - 7.5, but onion can also be grown in mild alkaline soils. Onion crop is more sensitive to highly acidic, alkali and saline soils and water logging condition.
