Documenting Nutrient Deficiency and Accumulation Rate in Vegetables

This collaborative project between Tennessee State University and IPNI continues to result in high resolution photographs of nutrient deficiency symptoms of important horticultural crops. The primary accomplishment of 2017 was the documentation of deficiency symptoms of Russet Burbank potatoes growing in hydroponics. Symptoms of nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, copper, iron, manganese, and zinc deficiency were induced in the greenhouse and carefully photographed. The collection of images was assembled into an e-book that is now available for purchase through the IPNI store (https://store.ipni.net/).

Plans for 2018 include the production of additional e-books documenting the nutrient deficiency symptoms of butterhead lettuce, Romaine lettuce, and cucumbers. This will augment the collection of previously completed e-books that currently includes broccoli deficiency symptoms.
