This trial looked at Serenade Prime as product to increase marketable potatoes and uniformity in tuber size through two applications during the growing season. Serenade Prime did not result in an increase of total yield but recorded an improved number of ‘marketable’ potatoes from the treatment through the reduction of smaller tubers and a higher percentage of medium sized, premium tubers. The trial was conducted near Dandaragan on sandy duplex soil.
This demonstration, featured at the 2015 Spring Field Day site was designed to show that, in the right season, ripping affects nitrogen uptake
efficiency and availability to crops. It was located in Dandaragan on red loamy soil and showed positive results.
Potato growers in the Gingin and Dandaragan areas face significant production challenges due to highly variable soil types under centre pivots. One problem during tuber establishment is where irrigation decisions for lighter soil types result in overwatering on heavier soil types, resulting in rotting of seed pieces on the heavier soils. On the other hand, optimizing irrigation for heavy soil types results in underwatering of seed pieces on lighter soils. The trial is being conducted in Gingin and Dandaragan on sandy and loamy soils respectively. This report covers the pre-trial testing results.
