Intensive pear production systems use more than 1,000 trees/ha. They aim for early returns on capital and consistent high yields of good quality fruit from lower labour costs.
The classification of what constitutes a high density orchard varies between production regions. For the purpose of this site densities are defined as follows:
Low density = <1,000 trees/ha
Moderate density = 1,000-2,500 trees/ha
High density = 2,500-4,000 trees/ha
Very high density = 5,000-8,000 trees/ha
Ultra high density = > 8,000 trees/ha
Intensive pear orchards can offer better production efficiency through:
- Earlier bearing and therefore quicker returns on investment;
- Improved fruit quality – up to variety-specific maximum densities where crop loads are managed;
- Better labour efficiencies once established (e.g. more efficient harvest and pruning/training).
When thinking of establishing intensive pear orchard, growers need to consider:
Nitrogen application in pear orchards. Fact sheet: discusses how to assess nitrogen status, calculate nitrogen requirements, fertiliser options and timing and method of applications.
Evaporative cooling in apple & pear orchards - used to prevent sun damage of the fruit by applying overhead watering and lowering fruit surface temperature.
