Abstract:

Seedlings of 35 loblolly pine (Pinus taeda L.) families were treated with five levels of urea in field plantings. The pattern of height growth response to increases in urea application was curvilinear during the first growing season after application; this response persisted at a lower level during the second growing season. In both growing seasons, family variance for height growth was low at urea levels that produced the highest mean growth, and high at urea levels that gave suboptimal mean growth. During the first growing season, both linear and curvilinear family response patterns were observed. Some families grew well at all urea levels, while others grew poorly at both high and low application rates but well at intermediate rates. Forest Sci. 22:291-299.
