Crop/cultivar |
Citrus/ Hongjiang Oranges |
|---|---|
| Country / location | China / Longdong state orchard |
| Objectives | Increase yield and improve quality |
| Haifa product tested | Multi-K™ |
| Application method | Foliar nutrition |
| Tested treatment | 4 x foliar feeding @ 2.5% or 5.0% & 1,500 lit./Ha |
| Control treatment results | Total yield = 40.5 MT/Ha. Fruit splitting rate = 11.4 Soluble solids = 11.5%. Peal: rough, opaque, yellow |
| Best treatment results | Total yield = 56.2 MT/Ha. Fruit splitting rate = 4.4 Soluble solids = 12.5%. Peal: fine, glossy, orange |
| Characteristics of best treatment | Yield increase: 15.7 MT/Ha. Splitting rate reduced by 7% Total soluble solids increased by 1%. Appearance much improved Therefore, 3 quality factors were markedly improved. Grower’s revenue from yield: 120.5 US$/MT Cost of treatment (application + material) 127 US$/Ha |
| Net benefit of best treatment | 1,774 US$/Ha |
| Benefit/Cost ratio | 14 |
| Conclusions | Local: Foliar feeding of orange trees is a very efficient tool for improving returns. Worldwide: The a/m conclusions were arrived at in many locations worldwide. |
| Reference | Cao Gong. Note: the experiment was run in 1993, but not yet included in Haifa reports. |
