Transcript

  • 1. Nursery Production The Key to a successful Industry Kim Wilson Gray Plantations
  • 2. “The Forgotten Sector”The nursery is equally important as the processor & grower.Poor quality trees are with you for the life of the orchard.Poor NIS prices are only there for 1 year!!!!
  • 3. Nursery Production in AustraliaNurseries & Orchard RejuvenationNurseries around the WorldNursery AccreditationNursery R & D
  • 4. Nursery Production in Australia• 30 years experience – watching• Demand for trees closely follows NIS price.• > 90% Grafted – H2 Rootstock• Small % - Budding & Cutting – variety related• Process – Germination - Sand beds – Potting up – 8lt bags – Grafting
  • 5. Nursery Production in AustraliaSeed germination18 – 24 months
  • 6. Nursery Production in AustraliaCurrently very strong demand (high NIS)  18 month – 24 month waitCurrent varieties North  842  A203  Daddow  741 South  842  816  246  741
  • 7. Nursery Production in AustraliaLot of nurseries come & go  Mainly due to waiting timeOnly two large commercial nurseries  Others supplying own needs  General fruit tree nurseries
  • 8. Nurseries & Orchard Rejuvenation• Obviously nurseries will play a big part – Commercial nurseries – Nursery for own use• Rejuvenation – Existing varieties – New varieties from breeding program• I believe anybody propagating the new varieties should require approval – AMS
  • 9. Nurseries & Orchard Rejuvenation• Based on current methods of propagation nurseries will require a large source of scion wood. – Preferably close to nursery – Trees need to be a few years old at least – Varieties clearly identified – These trees can’t be data trees• Release of Regional Variety Trial scion wood in the late 80’s??????????
  • 10. Nurseries around the World• Poor nursery stock• Poor orchards trees• Poor performance• Major influence on quality Potting Mix Water quality
  • 11. Brazil – Most good quality
  • 12. South Africa
  • 13. Vietnam – Most nursery poor quality – 1 very good quality 100,000 seedlings
  • 14. China – Many nurseries, mixed quality
  • 15. Thailand - Marcotting
  • 16. Burma – 100,000 seedlings
  • 17. Sri Lanka – Trials 2,000 trees
  • 18. Nursery Accreditation• The AMS has no official “Accreditation scheme”• Nursery Industry – N. I. A. S. A.• Strong demand = back yard nurseries Can lead to poor qualityI like the SAMAC system of “affiliated nurseries”
  • 19. Nursery R & D• Australian industry spend $2m / year on R&D• Zero $ on nursery R & D• Why do the two largest producing countries propagate in complete opposite ways?• Why do we still use H2 rootstock?• Cuttings – Large numbers would be difficult sell. !!!!
  • 20. Nursery R & D• Why don’t we “mini” graft?• Producing nursery stock is expensive & not very profitable. – Researched Avocadoes, Citrus etc – Most sell at higher price & quicker to grow• Perhaps there is an opportunity for joint R & D between countries!!!!!!!!!
