- Abstract
The aim of the study was to identify the abiotic factors that influence the onset of diseases in a salad (Lactuca sativa L.) var. romana and var. capitata, grown under polyethylene film in Sofia field. Based on the objective, we set plots experienced in duplicate salads with foil, and two plots without foil. In order to obtain comparable results we carried out soil sampling in advance to check the availability of nitrogen, phosphorus and potassium. The first inspection was conducted in February 2017 with an analysis of the presence of soil pathogens in the experimental plots. So far we have identified soil fungi of the genus Alternaria, Fusarium, Rhizoctonia, Botritis, Aspergillus, Penicillium and Mucor. The second inspection will be conducted before the active growing season, with a sampling of plants with disease symptoms and comparison of the microbiological parameters after the end of the salad growing season. Currently the results show a significantly better development of plants grown under the plastic film without the occurrence of pathogens threatening collapse of salad plants. After the final results, we sincerely hope to recommend to salad producers to implement the use of foil against the collapse of lettuce under the influence of low temperatures and pathogens.
