An investigation into the influence of preceding crop on the performance of potatoes and the influence of the following crop on soil-borne diseases began in 2015. This looked at the influence of the crop on key soil-borne diseases and the influence of the preceding crop on potato crop performance and yield. The treatments are include cereals, maize, onions, brassicas, grass and biofumigant crops.

FAR were successful with an application to MPI SFF.  The project will run for three years in Pukekohe, Manawatu and Canterbury and focus on ‘Increasing potato yield through understanding the impact of crop rotations and soil compaction”.

Year 1

Eighteen commercial potato field crops were evaluated for this season. The desired outcome of the project was to better understand where potatoes fit in the rotation, how to reduce soil compaction and improve soil structure whilst understanding how all these factors impact of soil-borne diseases. Comprehensively testing abiotic and biotic factors along with understanding the rotation and soil-borne diseases over three years will give us the full spectrum of how and where potatoes fit best along with understanding where we can increase yield.
