|---|---|
| Country / location | China / Shouguang /Shandong province |
| Objectives | Compare two potassic fertilizers: SOP vs. Multi-K |
| Haifa product tested | Multi-K |
| Application method | Base dressing & Fertigation |
| Tested treatment | 345 Kg/Ha K applied as SOP – base dressing 345 Kg/Ha K applied as Multi-K - fertigation |
| Control treatment results | Total yield in 0 K: 29.2 MT/Ha |
| Best treatment results |
Total yield in 345 Kg/Ha K applied as SOP: 33.7 MT/Ha Total yield in 345 Kg/Ha K applied as Multi-K: 35.8 MT/Ha |
| Characteristics of best treatment | Yield increase: 2.1 MT/Ha better than SOP, Frost hardiness was much improved, and so was marketability |
| Net benefit of best treatment | (Grower’s revenue from yield: 1,240 $US/MT) 2,603 US$/Ha |
| Benefit/Cost ratio | SOP – 9.6 ; Multi-K – 12.2 |
| Conclusions | Local: Multi-K was considerably superior to SOP. |
