Abstract:

The present investigation was carried out in old and senile apricot trees in the experimental orchard of the Department of Fruit Science, UHF, Nauni, Solan during 2011 to 2014. The experiment comprised of factorial combination of pruning severities (20%, 40% and 60% heading back of main scaffolds) and three levels of nitrogen dose (500, 625 and 750 g/tree). These experimental trees were given rejuvenation treatments for the first time in 2011. Treatment combinations of different pruning intensities and nitrogen levels were found to exert considerable influence on the soil and leaf nutrient status of the tree. The leaf N, Fe, Mn and Zn content increased with increasing pruning severity coupled with high dose of nitrogen, while leaf P, Ca, Mg and Cu content showed declining trends with the increasing pruning severity and nitrogen levels.
