Faba Bean Adaptation

Faba bean is a cool season crop, which prefers cool moist growing conditions. It is best adapted to the irrigated area of southern Alberta and portions of the Black soil zone with longer frost-free periods. The crop also grows well in the Peace River region as long growing days assist in shortening the days to maturity in this area

  • approximate days to maturity in Alberta are 126
  • faba bean is adapted to a wide range of soils, but appear to do particularly well in deep medium-textured soils that have a good water-holding capacity
  • faba bean performs poorly in shallow soils with a compacted layer near the surface, such as solonetzic types
  • soils below pH 6.0 should be avoided since nodulation may be affected – a pH range of 6.0 to 7.2 is recommended (soils with a pH above 8.0 may require a foliar application of micronutrients, based on a plant tissue analysis)
  • faba bean is moderately sensitive to salinity and should not be seeded in soils with a conductivity greater than 3.5 millimhos/cm
  • under conditions of high fertility and cool damp weather, the crop will be more indeterminate and mature later, resulting in feed grade
  • flower set is affected by high temperatures, especially above 28˚ C, for an extended time – hot, dry weather will cause wilting of the plants and will reduce seed set
  • faba bean responds well to irrigation or ample precipitation – the plant is sensitive to moisture stress and performs poorly where moisture supply is limited
  • seed faba bean as early as soil conditions permit, as seedlings are very frost tolerant
  • early seeding ensures maximum yield potential and allows the crop to mature before fall frosts can damage seed quality
