Abstract

The aim of this study was to be estimated the response of eight pepper varieties, accessions and breeding lines with different fruit shape and direction of usage in four systems of organic production and conventional variant used as a control. The field experiments were carried out during the period 2008-2010 at the Maritsa Vegetable Crops Research Institute, Plovdiv, Bulgaria. The total yield and some morphological characters of the fruit - length, diameter at the base and fruit weight were analyzed. The influence of the sources of variation on these characters was also determined. An organic production system with identical behavior of all studied pepper materials concerning the analyzed traits was not outlined during the whole experimental period. The variety Buketen 50 and accession К558 showed very good results by most studied characters of the fruit in the growing systems with bio pesticides use. Variety Stryama realized its yield potential in all organic production systems that confirmed its good adaptability. The exceeding towards the control variant of growing was with 19.49% in the system with Lumbrical (vermicompost) use without plant protection and up to 45.32% in system with Lumbrical fertilization and bio pesticides application. Breeding line 1186/06, kapia type, also demonstrated higher total yield in most organic system but it was with worse fruit characters than in conventional conditions of growing
