  • Bed making; Your beds should  be 1M wide with a 30 cm path between the beds. They should be raised to about 20cm higher. 
  • Installing Drip Lines: 3  or 4 rows of drip lines  per bed are ideal for onion farming . four drip line s increase the plant population which in turn increases water consumption nutrient requirement and yeilds.
  • Choosing drip lines ideal for onion farming: 15cm emitter drip line is the most ideal for onion farming. However, the 20 cm emitter drip line can also give good results.
  • Onion Transplanting spacing when using drip irrigation: Use 8cm inter-plant double spacing to get the highest plant population per unit area.
  • Onion Fertilizer Application when using drip irrigation: A farmer can use fertigation (Mixing soluble fertilizer with irrigation water) or do direct basal application.
