PGA Seasonal Notes for January 2019 by Dr Ben Thomas

We are now in the nut fill period of the pistachio production cycle which is a critical phase of the pistachio production cycle when the kernel grows and causes the shell to split. Good management during this phase will maximise kernel growth and shell splitting. Key issues at this time are understanding kernel development, managing irrigation and nutrition and preparing the orchard for harvest. This is also the time for leaf analysis and budding young trees.
