A comparison between OptiYield treated and Farm Standard portions of maincrop processing potatoes (var. Royal) conducted on 19th October 2018 at GooderWestwood. (Grid Ref.: 54.146921, -0.747831). By kind permission of the Wilson Family of CJ Wilson & Sons.

The trial 

3 x 2 m length row samples (17 plants) from each was lifted from adjacent treated/untreated beds in an otherwise uniformly treated crop and soil.

The Results

• 25% average increase in yield (12.32 T/ha)
• 7.74% increase in tuber count
• Significant increase in rooting
• Use of foliar biostimulants to reduce crop stress (esp. heat/drought) (NASPA project)
• Clean tubers – no noticeable disease
• Demonstrates power of Full Programme
