Profits and Black-grass
After a break crop, a first wheat can perform well, even with some black-grass present, achieving yields of 4t/acre. However, some farms are getting nearer 5t/acre and 4t/acre in second and third wheat.
Yet, if black-grass is present in the first wheat, then second and third wheats can become unviable. Spring crops may then be introduced into the rotations with limited herbicide options which, again, fill up with black-grass. The proftability of a farm with these issues can take a rapid downward spiral making a return to full profitability almost impossible unless the drilling system is changed allowing for late drilling of crops in all conditions.
Late drilling is highly profitable if you can get the seed set securely. Residual herbicide is more effective in late-sown damp conditions. Take-all will have subsided, and £120 herbicide stacks can be reduced as low as £20/ha.
Late drilling up to the end of January averages 4t/acre in HGCA trials. Click the button below for further information.
