Research performed in Italy shows: +20% marketable yield increase while using Haifa Multi-K™

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.
