Enhancing the profitability and value of New Zealand onions
We have base maps from topography and surface ponding analysis completed by Page Bloomer Associates, and from AgriOptics Dual EM soil mapping. We also have some previous crop data including true colour, false colour and NDVI images of winter cover crops between successive onion crops in these paddocks. More details here>
We are tracking crop development with a range of sensor technologies including AltusUAS MicaSense from UAV, Agricultural Software GroundCover app and some satellite imagery.
The collaboration with Plant & Food Research will help us develop protocols to monitor crop development and yield variation (spatially and temporally). Linking these with crop modelling and agronomy will help determine why variation is occurring.
Crops will be traced from paddock through harvest and storage so that post-harvest quality issues can be related to factors during growth. Linking paddock production to packhouse performance and back again may be key in unlocking value potential.
Grower led focus groups are involved in the project and analysis of results. They have a vital role in the development of practical tools they can use to monitor and quantify variability, to identify the causes of loss of yield and quality and share best practice to improve sustainability and grower returns.
