Potassium Applications And Yellow Shoulder Disorder Of Tomatoes In High Tunnels, Elizabeth Maynard, Israel S. Calsoya, Jill Malecki Jan 2017

Potassium Applications And Yellow Shoulder Disorder Of Tomatoes In High Tunnels, Elizabeth Maynard, Israel S. Calsoya, Jill Malecki

Purdue Fruit and Vegetable Research Reports

Tomatoes grown in unheated high tunnels can suffer significant loss in quality due to yellow shoulder disorder, particularly in susceptible varieties. This paper reports on a preliminary trial to determine whether incidence and severity of the disorder could be influenced by applying potassium fertilizers. Plots with higher leaf potassium content tended to have less fruit with severe yellow shoulder disorder, but increasing the amount of potassium fertilizer applied did not significantly reduce the disorder. From this study it isn’t possible to make specific recommendations for reducing yellow shoulder disorder with potassium applications.
