ABSTRACT

The aim of this study is to determine the effects of some organic substrates on growth characteristics and yield of local Bulgarian grapevine variety “Mavrud”. In parallel, organic and conventionally cultivated experimental plants were used. Concerning growth behavior indexes, in generous, the plants cultivated by conventional agriculture methods showed similar results to organic agriculture variants in all observed parameters compared with the non- treated controls. New organic substrate Kompovet B4® appeared to be the most convenient, confirming the results from the first and from the second year of the experiments. That could be an encouragement for including this substrate in the further grapevine organic farming technologies. Regarding the excellent quality of planting material as well as the novel forced greenhouse plant production methods- the first berry clusters were formed at the second year, instead of the third one (usually, the grapevines start harvesting on third year after cultivation). First obtained fruits in organic farming experimental field have a typical variety cluster form and raisin shape.
