Growth, cropping and leaf n content in ‘Jonagored’ apple trees depending on nitrogen fertilisation in autumn and rootstock

Abstract: The experiment was established in Warsaw-Wilanów in 2001. Jonagored apple trees on P 16 and P 22 rootstock planted in spring 1996, spaced 3.5 x 1.2 m were used. No differences in leaf N concentration were found in 2002 and 2003. Neither different N treatments or mode of N application had any marked effect on yield value or vegetative growth of trees. No significant response to autumn N feretilization was noted on fruit set and mean fruit weight either. Growth of trees and cropping depended on rootstock. Trees on P 22 showed a less vigorous growth, and yield per tree was lower in comparison with trees on P 16.
