Recently, breeders have released a number of new winter wheat genotypes suited to early sowing. In 2019, field experiments were conducted at two sites: Wallendbeen (southern NSW) and Wongarbon (central NSW) to determine the influence of phenology on grain yield responses for a set of 16 commercial and newly released genotypes in response to sowing date (SD).

The aim of this experiment was to determine the effect of sowing time, barley density and herbicides on brome grass control.

This experiment was conducted at Wallendbeen, typically a high rainfall area in the South West Slopes, to assess canola’s yield potential across different sowing dates in a high yielding environment. Varieties were chosen to represent a diverse range of canola types to compare the different phenologies (including winter types), the breeding type (OP – open pollinated vs hybrid) and herbicide tolerance (TT vs non-TT – triazine tolerant) on three sowing dates: late March, mid April and late April.

Change in sowing time can have multiple effects on crop-weed competition. Delayed sowing can provide opportunities to kill greater proportion of weed seedbank before seeding the crop, but weeds that establish in late sown crops can be more competitive on a per plant basis. This is one of reasons why farmers who have adopted early seeding have reported excellent results in crop yield and weed suppression.  Therefore, it is important to investigate sowing time in combination with other practices across different rainfall zones. The review of Widderick et al. (2015) also recommended research on sowing time in many crops.  Delayed sowing can also reduce crop yield so the gains made in weed control may be completely nullified by the yield penalty.

There has been some research already on crop seed rate on weed suppression but none of these studies have investigated the benefits of higher crop density in factorial combinations with sowing time and herbicide treatments. Crop seed rate is an easy tactic for the growers to adopt provided they are convinced of its benefits to weed management and profitability.  Furthermore, growers in the low rainfall areas tend to be reluctant to increase their seed rate due to concerns about the negative impact of high seed rate on grain screenings.
