This 1951 report documents the Forty-Second Annual Meeting of the Northern Nut Growers Association in Urbana, Illinois. It features technical papers on walnut, filbert, and pecan cultivation, addressing critical issues like magnesium deficiency, leaf scorch, and disease management for growers in the Midwest and beyond.

The Forty-Second Annual Meeting of the Northern Nut Growers Association, held in Urbana, Illinois, in August 1951, produced a comprehensive technical report serving as a vital resource for horticulturists and growers. The proceedings highlight significant advancements in nut tree production, focusing on cultivar performance, soil management, and pest control. A central theme of the report is the detailed analysis of the Jacobs Persian Walnut, a promising non-Carpathian variety for the Midwest that has proven regular bearing and high kernel quality. Comparative studies between Reed and Potomac filbert varieties reveal critical differences in vigor and disease susceptibility; notably, the Reed variety is approximately four times more susceptible to infection by the fungus *Labrella coryli* than the Potomac. The report also addresses the complex relationship between fertilizer treatments and tree health, demonstrating that high potassium applications, particularly when combined with nitrogen, can exacerbate magnesium deficiency in filbert leaves. This deficiency manifests as leaf scorch, which correlates strongly (coefficient of 0.97) with subsequent winter injury. While attempts to mitigate this issue with dolomitic lime and Epsom salts showed limited immediate recovery, the data underscores the importance of balanced nutrition. Additional sections cover the status of the Northern Pecan, timber value assessments, and propagation techniques. The volume includes extensive lists of association officers and members, reflecting the organization's broad geographic reach across the United States and Canada. Although some papers were deferred to the 1952 report, this document provides a substantial snapshot of mid-20th-century scientific inquiry into pest management, soil chemistry, and cultivar selection essential for successful nut growing.
