Abstract: The response of eight Bulgarian pepper varieties was studied in the conditions of organic production. A control variant without application of fertilizers and pesticides and conventional variant, according to the technology for mid-early production were used for comparison. The study was carried out on the experimental plot of the Maritsa VCRI, Plovdiv during the period 2007-2009. The plant height and total yield were analyzed. All factors had a proven role on the manifestation of yield and the interaction production system x year only had no proven effect on the plant height. The genotypic factor had dominant effect on the variability of the two traits. The year was classified on the second place (34.36%) according the influence on plant height while on the total yield – the system of production with 21.19% followed by the interaction genotype x year with 19.11%. It was established that in organic production conditions the varieties Stryama and Sofiiska kapiya were with close results by total yield towards the conventional ones.
