Effect of orchard factors and mineral nutrition on bitter pit in "Golden Delicious" apples.

Author(s) : SIÓ J., BOIXADERA J., ROSERA J.

Summary

The present five years of research is focused on the effects of field (orchard) and management factors in bitter pit incidence. The relationship between soil fertility, leaf and fruit mineral content, yield, fertilization, irrigation, cultural practices and orchard factors, and bitter pit incidence have been studied. Preliminary results show that bitter pit as usually correlated with Ca content and with K:Ca (K+Mg):Ca and N:Ca ratios, both in fruits and leaves. Shoot growth and yield were also correlated with incidence of bitter pit. The available preliminary results show that improved management of irrigation, K fertilization and soil fertility could reduce the incidence of bitter pit.
