Better vegetative development, higher quality of fruit in terms of increased fruit diameter and flesh thickness.
Yield and quality improved mainly due to higher number of fruits per plant, larger fruit size and flesh thickness
| Crop | Pepper / Peto PS 600 |
| Country / location | Italy / Tuscany – Val di Chiana cesa (AR) |
| Objectives | Compare PN vs. SOP for pepper |
| Haifa product tested | Multi-K- based Poni-Ter 18-11-23 & Multi-K Prills |
| Application method | Side dressing |
| Tested treatment | B.D. of Poni-Ter @ 830 kg/ha + S.D. of Multi-K @ 200 kg/ha after picking 1st cycle of fruit. |
| Control treatment results | Total marketable yield: 32.0 MT/ha Grower’s revenue from yield: 218 US$/MT |
| Best treatment results | Total marketable yield: 38.7 MT/ha Grower’s revenue from yield: 226 US$/MT |
| Characteristics of best treatment | Marketable yield increase: 6.7 MT/ha (21% above control), due to increase in No. of fruits/ plant. Better vegetative development. Higher quality of fruit in terms of increased fruit diameter and flesh thickness. Difference of costs between Multi-K and control treatments (application + material) 67 US$/ha |
| Net benefit of best treatment | 1695 US$/ha |
| Benefit/Cost ratio | 26.3 |
| Conclusions | A considerable increase in marketable yield due to the B.D. application of Multi-K- based fertilizer, followed by 2 x S.D. with urea and Multi-K prills at well-timed applications. The positive results are both in amount of yield and its quality, which was expressed by a small increase in price. |
