Overview

Randomized field experiment shows that high-frequency irrigation enhances sweet cherry tree growth and yield, indicating watering schedule affects orchard resilience under weather extremes.

Key Points

  • To evaluate the interactive effects of irrigation frequency, soil management practices, and crop load on sweet cherry vegetative growth, yield, and fruit quality in a cold climate.
  • Conducted a randomized split-split plot field experiment across six blocks from 2009 to 2011 using 'Cristalina' and 'Skeena' sweet cherry cultivars on Gisela 6 rootstock.
  • Applied two equal-volume irrigation regimens—high-frequency (four times daily) versus low-frequency (every other day)—alongside three soil management sub-treatments, including bloom-time phosphorus fertigation and wood waste mulching.
  • High-frequency irrigation elevated topsoil moisture (0- to 20-cm depth) and led to significantly larger trunk cross-sectional areas and higher fruit yields compared to low-frequency irrigation.
  • Low-frequency irrigation increased soluble solids concentration, whereas bloom phosphorus fertigation delayed harvest maturity and reduced soluble solids concentration without affecting vigor or yield.
  • Optimum fruit size occurred under lower crop loads between 100 and 200 g fruit/cm² trunk cross-sectional area, though cool, wet spring seasons severely depressed yields across all treatments.
