Abstract
  • This study was undertaken in a Red Delicious apple orchard in Oregon's Hood River Valley to determine if low leaf P concentrations were contributing to such observed, orchard disorders as poor shoot growth, shoot dieback and. small fruit size at harvest. Subsurface applications of lime and superphosphate had no effect on leaf P concentration, shoot growth and apple volume. Leaf P concentrations declined slightly (-.01% to -.02%) from 1978 to 1979 while shoot growth decreased (-6.2cm to -9.0cm) and apple volume increased (+31.12cm³ to +39.56cm³).
