Crop/cultivar |
Apple / Qinguan |
|---|---|
| Country / location | China / southern Shanxi province/ Linyi county |
| Objectives | Check Multi-K spray as a sole potassic fertilizer |
| Haifa product tested | Multi-K |
| Application method | Foliar nutrition |
| Tested treatment | 2 x Foliar feeding @ 1.5% & 2250 lit./Ha |
| Control treatment results | 65.1 MT/Ha |
| Best treatment results | 74.8 MT/Ha |
| Characteristics of best treatment | Yield increase: 9.7 MT/Ha Coloring rate and sugar content were markedly improved Cost of treatment (application + material) 42.7 US$/Ha |
| Net benefit of best treatment | 1125 US$/Ha |
| Benefit/Cost ratio | 26.4 |
| Conclusions | Local : The treatment had a very beneficial effect both agronomically and economically. Worldwide: Such treatments are bound to succeed in highly deficient conditions, as the current ones. |
| Reference | Cao Gong & Zhu Yao-Xin Note: the experiment was run in 1993, but not yet included in Haifa reports. |
