| Country / location | Germany / Speyer / Rinkenberghof Trial Station |
| Objectives | Increase of yield and quality, and compare CN vs. Multi-K as an N source. |
| Haifa product tested | Multi-K |
| Application method | Fertigation |
| Tested treatment | Fertigation (via overhead sprinklers) @ a total of 100 kg/ha of N, as: 1x 470 + 1x 200kg/ha of CN vs. 1x 470 kg/ha of CN + 1x 230 kg/ha of Multi-K |
| Control treatment results | Yield: 51.2 Mt/ha 1st Class product (units/ha): 22,700 Discoloration after X weeks storage: 19% Grower’s revenue from yield: 146 US$/MT |
| Best treatment results | Yield: 54.6 Mt/ha 1st Class product (units/ha): 26,500 Discoloration after same X weeks storage: 13% Grower’s revenue from yield: 200 US$/MT |
| Characteristics of best treatment |
Yield increase: 3.4 MT/ha (6.6% above control) Cost of treatment (application + material) 270 US$/ha |
| Net benefit of best treatment | 680 US$/ha |
| Benefit/Cost ratio | 2.5 |
| Conclusions |
Split applications of Multi-K increase total yield and improve its quality. It also extends its storability. These treatments should be tried also in adjacent countries having similar soil and weather conditions. |
