In our final year of “Benchmarking Onions” we have again planted a crop at the MicroFarm. It went into a suitably moist soil, emerged reasonably evenly but has shown increasing variation. We now have very good areas and very disappointing areas. 

We’ve mapped the crop with our CoverMap system again this season so we can compare 2015-16, 2016-17 and 2017-18 growth patterns. Are there areas that consistently perform better or worse? What is driving the variation we see?

We also have a few different varieties we are tracking to see how canopy development fits our web calculator. We want to know if the same calculations can be applied to phone images or if variety-based tweeks are necessary.

In a couple of fertiliser application trials we comparing standard and late application because we understand most nitrogen is taken up at or after bulbing. And based on our mapping, we are comparing the effects of full and half rates on areas where canopy cover is low. Maybe we can cut back, save fertiliser and leaching and get the same yield with improved bulb quality.

Come along and see for yourself!
