Chickpea competition with annual ryegrass locations

To identify chickpea plant types which are more competitive with ryegrass.

Key messages
  • Although chickpea yields were higher than previous years at Hart, the rapid finish to the season favoured earlier flowering and maturing varieties such as GenesisTM079 and Sonali.
  • Ryegrass competition at 31 and 86 plants/m2 reduced chickpea grain yield by 31% and 56%, respectively.
  • Breeder’s line “Chickpea 4” recorded the lowest yield loss from ryegrass competition at both sites (9% at the low ryegrass density at Hart), and also displayed 35% better tiller suppression than other varieties at Hart.
  • Early vigour appeared an important trait in chickpea for improved competiveness with ryegrass, whilst short plant height was a disadvantage.
