CONSIDERATIONS ON IRRIGATION

• If rainfall is regularly insufficient for target yields a reliable and affordable source of supplementary water for irrigation must be developed.
  
  
• Gravity flow or flood irrigation is usually more manageable for smallholders than sprinkler or drip irrigation.
  
  
• Water conservation measures can reduce or even eliminate the need for supplementary irrigation.
  
  
• If affordable irrigation and water conservation methods are not feasible the area is unsuitable for vegetable production and should not be chosen.
