| Characteristics of best treatment |
A remarkable and highly significant increase in export quality fruit due to decreased rind defects. An antagonistic effect on fruit internal quality: slightly reduced TSS/acid ratio, and increased juice content. |
| Benefit/Cost ratio | 34 |
| Conclusions | One foliar application of Multi-K suspension resulted in a remarkable increase in exportable fruit ratio and grower’s income. The positive effect is related to higher K content in the fruit rind. |
