The Northern Nut Growers Association Report of the Proceedings at the Twenty-First Annual Meeting details the key discussions and advancements made at the 1930 meeting, which was attended by nut growers, horticulturists, and agricultural researchers. This annual event continued to focus on improving the cultivation of nut species, such as walnuts, chestnuts, and hickories, particularly in the northern United States. Emphasis was placed on improving orchard management practices, increasing yields, and addressing ongoing challenges related to pests, diseases, and environmental factors.A significant portion of the meeting was dedicated to the issue of chestnut blight, which continued to devastate orchards. Experts presented new research on disease-resistant varieties and grafting techniques to help mitigate the impact of this destructive disease. Additionally, new findings in soil health, fertilization methods, and pest control were discussed, as well as innovative approaches to increasing nut production while maintaining the health of the trees.
