Water use and the irrigation requirements of hazelnuts in Australia


The project will be conducted in a young commercial orchard of hazelnuts on the property Drynane, which is located near Forest Reefs, 20km south of Orange. The orchard is on a property of Fourjay Farms, a business involved in the propagation, production, harvesting and processing of hazelnuts. There will be four levels of irrigation applied via an automated drip irrigation system in the period November end January, with two capacities of emitters. Soil moisture will be monitored via Sentek soil moisture probes. The climate will be recorded using an Environdata automatic weather station. Measurements will be made of tree growth, nut yields and kernel quality.

Objective Summary

1. To assess the effects of irrigation applied during some key developmental phases of nut 2. To assess the effects of volume of delivery of drip irrigation emitters on the volume of wetted soil and its influence on growth and production 3. To utilise moisture sensors to monitor soil moisture levels and root activity in a developing hazelnut orchard 4. To compare a range of irrigation scheduling techniques, including high and low cost soilmoisture monitoring equipment as well as evapotranspiration methodologies, and report to growers the most cost effective technique.
