2. Good drainage and nutrient/moisture
retention
Tolerant to compaction
Sandy loam, clay loam
Is organic matter content important?
◦ Very important for root development and
nutrient/moisture retention
3. Distribution critical
◦ Pollination: < 0.2 PET
◦ Nut Size: 0.2 – 0.4 PET
◦ Oil Accumulation: 0.5 – 0.6 PET
Would you utilise irrigation?
◦ Need depends on rainfall pattern
◦ Irrigation critical for Nut Size and Oil Accumulation
period when rainfall inadequate
4. Sufficient to provide economies of scale for
cost efficient operations
Would it be staged plantings or all in one
planting?
◦ Plant schedule dependent on finance and
availability of preferred grafted cultivars for the
site
5. HAES: 294-Purvis, 344-Ka’u, 508-Kakea,
800-Makai
Would you use pollinators?
◦ Cultivars to serve as pollinators for each other.
6. Minimum: 7.6 x 7.6 meters or greater
What row configuration would you plant?
(east/west or north/south or on the contour?)
◦ North-South
What is the maximum length per row?
◦ 500-600 meters
7. Would you mound the rows?
◦ Not Necessary
◦ Grade land to allow mechanized operations
(planting shade tolerant grasses?)
◦ Establish grassed water-way on a contour at 150
to 300 meter interval within the field to trap
eroded soil and minimize run-off into streams.
8. Year 5 production target = 0.03 (tonnes of
SK/ha)
Year 10 production target = 0.68 (tonnes of
SK/ha)
Year 20 production target = 1.41 (tonnes of
SK/ha)
11. Please incorporate any additional
ideas/points/issues you feel are important.
◦ Compile as much environmental data for orchard
site: Climate, Soil, Irrigation
◦ Select Cultivars with compatible bloom periods,
nutrient requirement, drought tolerance, pest
resistance, kernel quality retention during delayed
harvest.
◦ Cultivar growth rate at selected site to determine
tree space and plant configuration
