Abstract

U istraživanjima provedenim u proljeće 2015. godine na lokaciji Stupno (pokraj Siska) uspoređivana je brzina dozrijevanja jagoda pod različitim pokrovima, te masa ubranih jagoda za sorte 'Alba' i 'Clery'.
Pokrovi koji su se koristili su prozirna PVC-UV folija debljine 150 mikrona i polipropilenska (Lutrasil) folija težine 23 grama/m2. Ova dva pokrova su uspoređivana s uzgojem jagoda na otvorenom bez zaštite od proljetnih mrazova.
U drugom dijelu istraživanja pažnja je bila posvećena težini ubranih jagoda mjerenim u tjednima berbe u prosjeku po biljci i skupno u kilogramima po određenom pokrovu.
Što se tiče praktičnih saznanja o dinamici plodonošenja i vremenu dospijevanja plodova najboljim za ranu proizvodnju jagoda pokazao se onaj dio pokusa koji je bio pokriven PVC-UV folijom debljine 150 mikrona. Kod ovakvog načina proizvodnje vidljivo je da se proizvodnja jagoda i prisutnost na tržištu ubrzava za skoro 2 tjedna za razliku od konvencionalnog uzgoja na otvorenom i ovaj dio istraživanja može biti od koristi proizvođačima za planiranje proizvodnje u relativno sigurnim i konstantnim uvjetima.

Abstract (english)

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.
