Grateful for rain on the 15 tonne plots
Todd Jex, Agrii Agronomist
The 15 tonne challenge plots have developed well this spring on the back of a robust autumn and spring management programme. Our attention now turns to keeping the disease off the flag leaf as it begins to emerge. The last 6 weeks weather has led to increased disease pressure and will continue to put fungicide programmes to the test.
Reading the Farmers Weekly recently it was suggested that the pressure from septoria tritici this season is the highest it has been for over a decade, so it comes with no surprise that it is also our main concern in terms of disease on the R&D site. This will make for a fantastic test of the new SDHI chemistry compared with existing fungicides. We identified nutrition as an area which we could focus on to try and drive the yield forward.
To date the 15 tonne plots have received just shy of 200 Kg/ha of nitrogen, with another 130 Kg/ha planned to be applied in two doses. The plots have already received all of their phosphate and potash as well as the majority of their sulphur and magnesium. Regular tissue tests have allowed us to assess nutrient content right down to the micro level in the plant and thus apply foliar nutrition to raise levels where they are suboptimal. It will be interesting to see how the different plots perform and whether or not we meet our 15 tonne ambitions!
We hope you will join us on Thursday 21st June on the R&D site at Manor Farm, Stapleford, Wiltshire for a final look around the plots prior to harvest.
Here’s hoping for some dry weather for now and harvest.
