Summer weed trial locations
Aims

To determine which summer weed control method is most efficient and economical.

Key messages
  • In dry regions, summer fallowing is not just about controlling weeds but mainly about conserving moisture!
  • Cultivation conserved the most amount of soil moisture over the summer period. ƒ
  • The three treatments which controlled summer weeds: (i) cultivation every three weeks; (ii) cultivation when required; and (iii) knockdown when required, had a significantly higher yield (0.4 to 0.7 t/ha) compared to the treatments where there was no or poor summer weed control. ƒ
  • Greater than 80mm of available moisture was lost under heavy heliotrope and melon populations
