New Publication Addresses Plant Nutrition Diagnostics in Potatoes

Good nutrition is essential for supporting potato plant health and providing the necessary defense against plant disease and stress, says Robert Mikkelsen, vice president, Communications, International Plant Nutrition Institute (IPNI).


The IPNI, J.R. Simplot Co., and Tennessee State University have collaborated on a new publication that provides readers with access to a unique collection of hundreds of high resolution photographs that document a wide range of nutrient deficiency symptoms in potato plants with remarkable clarity.

“IPNI is fortunate to collaborate with Dr. Pitchay (Tennessee State) and Simplot in producing this world-class collection of photographs and information,” says Mikkelsen, who co-authored the book along with Dharma Pitchay.

Developed within a unique greenhouse system at Tennessee State University, this collection provides examples of mild, moderate, and severe cases of deficiencies of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), boron (B), copper (Cu), iron (Fe), manganese (Mn), and zinc (Zn). The identification of nutrient deficiencies in the field can be a difficult process and this collection provides farmers, crop advisers, and mineral nutrition researchers with a valuable diagnostic tool. Once the underlying deficiency is known, strategies can be developed to help avoid losses in yield or crop quality.

“This has been a tremendous opportunity to work with leading scientists to develop a world class collection of fully documented photos describing the major crop nutritional problems commonly observed in the field,” explains Dr. Terry Tindall, director of agronomy for Simplot.

The book is now available to download from the IPNI Store.
