Site 3, Minnipa, SA
To investigate factorial combinations of sowing time, seed rate and herbicides on the management of annual ryegrass in wheat.
Wheat grain yield at Minnipa was significantly influenced by the time of sowing (P=0.002), seed rate (P<0.001), herbicide treatment (P<0.001) and the interaction between the time of sowing and herbicide treatments (P<0.001). Averaged across the seed rates and herbicide treatments, wheat produced grain yield of 1.67 t/ha in TOS 1 as compared to 1.06 t/ha in TOS 2. There were large benefits of delayed sowing on weed control. However, these benefits came at a significant cost in wheat grain yield.
