Title: Research Note: Seasonal Patterns in Above Ground Growth and Nut Abortion in Young Eastern Black Walnut Trees
Authors: D. Ross and D. Brauer
Abstract:
Eastern black walnut (Juglans nigra L.) is an excellent choice for agroforestry practices in the eastern United
States because of its value for nuts and timber.
A better understanding of the seasonal growth pattern of black
walnut may provide insights that will lead to improved management protocols for optimum tree and nut production.
Monthly variations in nut diameter, trunk diameter and tree height were followed for black walnuts located
near Booneville, Arkansas, USA. Nut abortion was followed periodically from June to September.
No significant
increase in either trunk diameter or tree height was observed after August during the growing season.
Most nut
abortion occurred before August.
These results indicate that optimum nut and tree production will result from
management protocols that promote early season growth.
