Agrizest Trial Summary 4: Kiwifruit
Effect Of Agrizest Treatment On Fruit Quality, Yield And Orchard Gate Returns Compared To A Foliar Fertiliser with “vitamins, amino acids, growth factors…”
Te Puke, New Zealand
2018/2019 Season results.
To Show That Agrizest will:
1. Lift Orchard Gate Returns
2. Improve Fruit Quality.
plus compare the performance of a maturity block treated with Agrizest to a block treated with a foliar fertiliser spay.
The trial was carried out in response to claims that a foliar fertiliser is ‘the same as Agrizest’.
This is a trial summary, a full trial report and data from additional trials is available on request.
Trial Design: Split block, independent, commercial scale trial.
‘Treated Block’ – One maturity area was treated with Agrizest.
Agrizest was applied as per label at 1 litre per hectare applied twice before flowering and twice after flowering.
No foliar nutrient sprays were applied.
‘Foliar Fertiliser Block’ or ‘Control’ – the other maturity area received the foliar fertiliser sprayed at a rate of 2.5 litres per hectare. The spray is a foliar fertiliser claimed to contain vitamins, amino acids and proteins, betaines and growth factors.
The sprays were applied by the orchardist/contractor.
All other treatments, pruning etc. of the blocks were the same.
This is a large split block trial to eliminate random errors.
The total crop was evaluated to eliminate sampling errors.
Quality and yield aspects were electronically detected or measured to avoid subjective assessment errors.
Final Pack-Out Data
The final pack-out data shows that the Agrizest treatment delivered:
1. Increased yield (+3000 trays/ha)
2. A 19% increase in fruit payment
3. Higher TZG payment. Note: The TZG of the fertiliser block was slightly higher than the Agrizest block, however, the fertiliser block was harvested later than the Agrizest block.
4. A 33% reduction in rejects
5. An increase in in Orchard Gate Returns (an additional $20,558 per hectare) compared to the foliar fertiliser treated area.
Kiwifruit treated with Agrizest outperformed blocks treated with a fortified foliar fertiliser in terms of tray numbers, fruit payment, TZG payment and reduced rejects.
Agrizest treatment increased orchard gate returns by $20,558 per hectare compared to the foliar fertiliser.
This trial clearly demonstrates that the Agrizest treated block outperformed the area treated with the foliar fertiliser spray.
Agrizest is not a foliar fertiliser. Agrizest works by eliciting the phenylpropanoid pathway: bioactive molecules that enable optimal plant health and fruit quality https://www.zestbiotech.co.nz/agrizest.
