One thing this forum shows is that what one person does in not right or somebody else is wrong, crop husbandry has several fundamentals and the rest is decisions based on experience and opinion.
There's no doubt agronomy is subjective, there's no right or wrong and only hindsight will prove whar was or wasn't correct.
A solid base should underpin it all though.
Sounds very sensible to me.I look after a friends crops who didn't drill until Jan/Feb, he crops will never yield 4t/ac no matter what we throw at it so all it has had so far is 1.0 Cherokee with Manganese, etc and will get a GS39 spray of SDHI and a tick the box tebuconazole on the ear, total cost no more than. £50 per ha. Compare this to where I have good crops which still have great potential we shall probably end up around £70-80 per ha, so agree can reduce when yield potential has gone......that said no matter what we do if the sun doesn't shine during grain fill yields will be hit, all we can do is ensure crop is in best possible shape when we enter that period
