Abiotic constraints in Canola
Broad constraint resources are outlined in the Agronomists Toolkit. Specific constraint categories are listed below:
Constraint - Re-shot plants
New branches emerge from stressed or dying plants, once the stress has been overcome and conditions are more favourable
Late rain after drought conditions may encourage the plant to reflower
This makes decisions around harvesting dates very difficult
Yield can be greatly reduced
There are no treatment options. Close observation of the crop to optimise harvest timing, and management of stresses that can be controlled, such as nutrient deficiencies, will help to minimise the risk of re-shot plants.
