So we are now within a month of when we'd normally start top dressing our rape.
This year we have a massive canopy (all significantly above GAI 1 already), from a combination of high plant numbers and plenty of leafy growth. Some flea beetle activity and some background phoma. Put some teb on with the kerb last week and thinking definitely PGR at early stem extension.
But when do I start top dressing and how much? Normally 3 splits and 170-210kgN/ha. This time thinking 150-160kgN max and delaying first application till early March depending on weather in February. I reckon there's plenty of N to remobilise from existing older tissue before I apply any bagged fertiliser.
What are your thoughts on your crops?
