Crop type: Canola 1 trial Sowing Timing Variety Type
Binnu, WA
Source Data Unavailable
Research organisaton
Funding source

Aims:

To investigate whether agronomy can overcome the yield penalty of retained (F2) TT hybrid canola compared with purchased (F1) hybrid seed by using;

  • seed mixes.
  • increased density or,
  • grading to increase seed size.

Aims:

To compare the plant density response of yield and oil content between hybrid and open-pollinated (OP) canola in Triazine tolerant (TT) and Roundup Ready (RR) herbicide tolerance groups.

Crop type: Canola 1 trial Sowing Rate Variety Type
Wongan Hills, WA Loamy sand
Source Data Unavailable
Research organisaton
Funding source

Aims:

To investigate the response to changing the nitrogen rate and changing the time of application.  Canola yield and oil will be measured and RR hybrids will be compared with open-pollinated TT types (OP TT).

Crop type: Canola 1 trial Fertiliser Type Fertiliser Rate
Wongan Hills, WA Loamy sand

Aims:

Aim; To investigate the response to changing the nitrogen rate and changing the time of application.  Canola yield and oil will be measured and RR hybrids will be compared with open-pollinated TT types (OP TT).

Previous trial results suggest that as long as nitrogen is applied within 8 weeks of sowing, there is no yield penalty.

Aims:

To investigate the nitrogen rate and time of application response of canola varieties to yield and oil content of TT and RR hybrids in comparison with open-pollinated types to

  • provide growers in lower rainfall environments with guidelines on optimal nitrogen rates and times of application to maximise grain and oil yields, andread more
Crop type: Canola 1 trial Fertiliser Rate Fertiliser Timing
West Wubin, WA Sandy loam

Aims:

To identify differences between commonly grown wheat varieties in their ability to emerge from very deep sowing (100mm) and relate to coleoptile lengths and to quantify the effects of deep sowing on grain yield.
