In surveys conducted in the spring of 2015. on location Stupno (near Sisak) compared the rate of ripening strawberries under various covers, and mass-picked strawberries for variety 'Alba' and 'Clery'. Covers that were used are transparent PVC-UV film thickness of 150 microns and polypropylene (Lutrasil) foil a weight of 23 grams/m2 . These two cover are compared with cultivation of strawberries in the open without protection from spring frosts. In the second part of the research attention has been paid to the weight of harvested strawberries measured in weeks of harvesting on average per plant and the total in kilograms by a certain cover. As far as practical knowledge about the dynamics of fruiting and the time of reaching the best fruits for the early production of strawberry has proved to be one part of the experiment, which was covered with PVC-UV film thickness of 150 microns. On this type of production, it is evident that the production of strawberries and market presence accelerates for nearly two weeks as opposed to conventional farming in the open and this part of the research can be of benefit to producers for production planning in a relatively safe and constant conditions.
