Benefit of irrigation for high value grain legumes locations
Aims

To determine yield and quality benefits from irrigation of high value grain legumes. Further studies will determine the most appropriate timing of irrigation.

Key messages
  • Irrigation resulted in a 60% and 400% increase in grain yield for broad beans and marrowfat peas respectively.
  • Irrigation resulted in a 17% and 3% increase in seed size in broad beans and marrowfat peas respectively. This is critical in producing for markets requiring large seed size.
  • It is likely that the dry finish to the season (decile 1) enhanced the positive effects of irrigation particularly for the marrowfat peas and other spring sown crops.
  • In addition to the capacity to irrigate and a cool seasonal finish, Tasmania has other advantages in marrowfat pea production that can be capitalised upon ie - excellent adaptation of overseas spring germplasm and freedom from pea weevil.
