Abstract:
〈 p class="Default" 〉 〈 strong 〉 Background 〈 /strong 〉 . The electrical conductivity (EC) of a nutrient solution (NS) in hydroponic or soilless systems influences the yield and quality of the fruits. 〈 strong 〉 Objective 〈 /strong 〉 . The aim of this research was to determine the quality and fruit yield of bell pepper in response to the electrical conductivity of the nutrient solution. 〈 strong 〉 Methodology 〈 /strong 〉 . A completely randomized experimental design with 15 replications was used. The treatments consisted of four nutrient solutions with different electrical conductivity (1.5, 2.0, 2.5 and 3.0 dS m 〈 sup 〉 -1 〈 /sup 〉 ) based on the Steiner nutrient solution. Yield, firmness, and bioactive compounds (phenolic compounds, vitamin C, lycopene, β-carotene, and the antioxidant activity) were quantified in fruits. 〈 strong 〉 Results 〈 /strong 〉 . The results showed that an electrical conductivity of 2.0 dS m 〈 sup 〉 -1 〈 /sup 〉 or higher increased the bioactive compounds but decreased the yield and firmness of the fruits. 〈 strong 〉 Implications 〈 /strong 〉 . The correct selection of the EC in the NS is a preponderant factor to get functional foods, with high yields and to avoid unnecessary costs in fertilization 〈 strong 〉 Conclusion 〈 /strong 〉 . The high EC in the NS reduced the yield and the firmness of the fruits. From an EC of 2.0 dS m 〈 sup 〉 -1 〈 /sup 〉 in the NS, the content of vitamin C, total phenols, lycopene, total capsaicinoids, β-carotene and the antioxidant activity of pepper fruits increased. 〈 /p 〉
