Nitrogen and rootstocks effects on tree establishment and precocity trial

This research aims to identify appropriate fertigation practices for different scion varieties on different rootstocks planted in a current industry standard (“H1”) planting layout with respect to establishment and precocity.

Across many horticultural crops the same scion growing on different rootstocks will have differing mineral nutrient levels in the leaves. Despite this, rootstock is not a factor considered in fertigation programs. The issue to be addressed in this trial is whether the ability of different almond rootstocks, particularly those recently introduced into Australia, to take up and transport mineral nutrients to scions grafted on to them is important in establishing and producing their first significant crop.

This trial also serves to provide a study platform for the future assessment of new technologies to assist orchard management, and to assess the impact of management and weather patterns on kernel development.

The major outcome sought from this trial is more appropriate fertigation regimes for trees on different rootstocks across the industry.
