Jujube quality management

Page last updated: Monday, 10 August 2020 - 11:49am

This page aims to assist growers to consistently deliver quality jujubes to consumers.

Introduction

To maximise profits, jujube quality should be managed from selection of the orchard site through to transport to the market. There are many factors throughout production that will influence the quality of the product including:

  • Variety selections
  • Quality of propagating material
  • Irrigation and nutrition management
  • Training and pruning
  • Pest and disease control
  • Harvest
  • Postharvest storage, packaging and transport

Variety selections

There are currently around 15 jujube varieties grown in Australia. Some are fresh eating varieties, some are best for drying or processing while others are multipurpose. Selecting the right variety for your end product will be an important factor in the final quality of your fruit. Table 1 outlines the varieties available in WA and their best use.

The quality of the propagating material will also influence fruit quality. Detecting and treating diseases in nursery stock will ensure good quality planting material for the industry.

Planting a mixture of varieties with different maturity times will allow you to extend your season and manage at peak times such as harvest.
