Linseed v Weeds
The linseed plant is especially sensitive to weed competition, which limits its potential yield.
Trials work has looked at growing linseed with and without weeds at different stages of its development.
The critical period for competition was determined as starting 30 days and ending 80 days after emergence.
Linseed yield decrease was (commercially significant) greater than 10% during this critical period. The maximum yield decrease was 79% but we all know the crop can be a 100% loss where nothing is done.
The results suggest that weed management must continue over and extended periods and should not be halted prematurely.
Currently black grass seems to be the most commonly occurring weed within the linseed crops which have now been in the ground approximately 30 days.
