The influence of different biofertilizers on certain yield components and the yield of pepper

Abstract

In recent decades, awareness of the necessity to consume safe and healthy food has been increasing. Considering the importance of pepper, this study investigated the effects of microbiological preparations—effective microorganisms (EM) in the form of EM Aktiv and Trichoderma spp. (Vital Tricho)—under protected organic cultivation on fruit number, fruit weight, and total yield per plant across three years. Results showed that both year and microbiological treatments significantly affected most parameters. Vital Tricho increased fruit number per plant by 1.34%, fruit weight by 0.17%, and total yield by 12.57% compared to EM Aktiv, while increases were even more pronounced compared to the control. The results highlight the potential of microbiological fertilizers to enhance yield and ensure safer organic production of peppers
