Weed competition in chickpeas locations

To determine whether varietal differences in chickpea plant architecture affect their competitiveness with ryegrass.

Key messages
  • Although chickpea yields were higher than previous years, 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. Similarly, at Turretfield ryegrass at 41 plants/m2 corresponded to 33% yield loss, and 62% at 123 plants/m2.
  • Similarities between moisture stresses caused by lack of finishing rainfall in 2009 and from
    competition with ryegrass meant that the same varieties yielded well with or without  ryegrass competition eg GenesisTM079.
  • 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 competivness with ryegrass, plant height was a disadvantage, but further work is required on a larger set of
    phenotypes and in a more favourable growing season.
  • Some ambiguous results in 2009 (eg PBA Slasher and Chickpea 2) may be due to the
    unfavourable seasonal conditions for chickpea production which prevailed in SA last year.
    However they do indicate the need for more work in a more favourable growing season, and
    potentially on a larger set of phenotypes.
