Materials &Methods: In this experiment, the effect of four nutrient solutions (Hoagland 1, Hoagland 2, England and Knop) on the fruit yield and quality were evaluated. The experiment was carried out as a factorial based on randomized compelet block with three replication, in which the first factor was the four nutrient solutions and the second was the two pepper cultivars (Dimaz and California wonder). Traits related to physiological characteristics (chlorophyll index, leaf nitrogen, phosphorus and potassium content) and pepper fruit characteristics (fruit length and diameter, TSS, EC, titratable acidity and vitamin C) were assesed. Results: According to the results, Dimaz cultivar has the highest fruit total soluble solids (TSS) and pH. The highest chlorophyll index (49.5 spad units) was obtained in Hoagland 1 nutrient solution. The interaction of nutrient solution and cultivars on leaf nitrogen concentration was significant, so that the highest amount of nitrogen obtained in the combination of Dimaz variety with Hoagland 1 (3.2 mg/g DLW) and Hoagland 2 (1.3 mg/g DLW) and Californiawander cultivar with Hoagland 2 (3.15 mg/g DLW). The highest concentration of leaf phosphorus were observed in treatment combination of Hoagland I with Californiawander cultivar (1.9 mg/g DLW) and the English nutrient solution with the Dimaz cultivrs (1.85 mg/g DLW). Conclusion: According to the results, England nutrient solution with a favorable effect on some qualitative characteristics was introduced as the most suitable nutrient solution for pepper cultivation in our experiment.
