Nitrogen Improves Growth of Populus Deltoides Nursery Stock

The most convenient method for producing cuttings of cottonwood (Populus deltoides Bartr.) is by establishment of a cutting nursery (3). But, very little is known about nutritional requirements of the species. European workers report that nitrogen supply frequently limits growth of cottonwood (4, 2) however, Seth and Desarber (6) warn that excess nitrogen may make poplars more susceptible to fungal parasites. Mitchell and Chandler (5) suggest that a foliar nitrogen concentration of 2 percent is a minimum for satisfactory growth of Populus tremuloides Michx. The present investigation was to determine the influence of nitrogen supply upon growth of cottonwood cuttings and concentration of major nutrients in the foliage.
