Wheat at GS 30-31 at Adwick Grange

25 March 2014

The wind is proving tiresome, often preventing us getting on with fieldwork, but we are snatching all opportunities that come along to apply fertiliser and sprays.  Our oilseed rape has pretty much received its final ‘bagged’ nitrogen doses, with final applications ranging from 160kg/ha to 200kg/ha depending upon GAIs and yield potential.  The oilseed rape had a definite growth spurt last week and has rocketed to green/yellow bud stage very quickly.

Wheat too has grown quickly and with GS 30-31 upon us, T0 treatments for our wheat are the next job on the list.  With low levels of mildew, septoria tritici on older leaves, and the presence of yellow rust on some of the Agrovista variety trial plots; a mixture of cyproconazole and chlorothalonil, in whatever form it comes in, would seem to be the most economic and broadest means of control.  My AHDB Cereals & Oilseeds variety plots of Hytek, Gallant and JB Diego are still showing visible differences, with Hytek still being a striking green and having the lowest disease levels.

While taking samples from these plots to monitor disease and growth stage, I had a little £10 wager with Pat that every plant would have a worm attached to it. Needless to say, the soil organic matter and a little bit of worm charming kept my money safe!

The cost of production exercises that I’ve done through the Monitor Farm project has made the decision to sell some wheat forward a little easier, with last week’s rally in the markets.  I will be keeping a keen eye on America’s weather and Mr Putin’s army.
