Description:
Growth responses of a young, naturally regenerated Abiesbalsamea stand managed for Christmas trees in Nova Scotia were measured over the 2 years after application of dolomitic limestone and factorial combinations of four levels of N, two levels of P, and two levels of K. In the first season, nitrogen-treated trees were darker green and had heavier terminal buds. Other significant responses owing to nitrogen were greater numbers of apical and lateral buds in the second season and greater length of leaders, lateral shoots, and needles in both seasons. The only significant main effect of P was on bud development. Neither K nor lime had any significant influence, and no significant interactions among any nutrients were detected. Growth responses did not differ significantly among three rates of N application over the 2-year period indicating.that for short-term cultural purposes the higher rates are inefficient on this site.
