The use of plastic mulch films in agriculture had its beginning in the middle of last century and since then its use has been intensified, with all the environmental problems related to their disposal .The biodegradable mulch films, which can be incorporated in the soil at the end of the crop cycle,appear as a possible solution for this problem. The goal of this work was to assess the performanceof five biodegradable mulch films when comparing to conventional polyethylene (PE), in strawberry production (Fragaria × ananassa Duch.). The field tests were performed for two years in the region of Ribatejo—Portugal.
