Abstract

Budući da paprika ima visoke zahtjeve za vlagom tla, nužno je u tehnologiji uzgoja regulirati i
smanjiti gubitak vlage primjenom različitih malčeva. Cilj istraživanja bio je utvrditi režim
vlažnosti tla u vegetaciji paprike pri primjeni različitih malčeva (organski - ovčja i filcana
vuna, crni PE-film te nemalčirano tlo kao kontrola). Uzorkovanje tla za praćenje dinamike
trenutačne vlage obavljeno je dekadno s dubina 0 – 10 cm i 10 – 20 cm. Analiza varijance
svih provedenih mjerenja vlažnosti tla, pokazala je da su na sadržaj vlage u tlu statistički
značajno utjecali dani nakon sadnje paprike i vrsta malča. Obzirom na različite tretmane
malča, utvrđeno je da postoje statistički značajne razlike između ovčje i filcane vune u odnosu
na PE-film i nemalčirano tlo. Tijekom vegetacije, najviše vlage u tlu sačuvano je pod
organskim vunenim malčevima. Obzirom na dobivene rezultate, opravdana je preporuka
korištenja ovih malčeva kao alternative konvencionalnoj upotrebi polimernih materijala poput
PE-filma.

Abstract (english)

Since cultivation of bell peppers require very humid soil, it is of utmost importance to
regulate and reduce the loss of moisture during the cultivation period by using various types
of mulch. The aim of the research was to determine the soil moisture regime during the
growing period while using various types of mulch (organic - sheep and felt wool, black PEfilm
and unmulched plots as control plots). The soil sampling for analysis of moisture
dynamics was carried out every ten days. The samples were taken at depth of 0 – 10 cm and
10 – 20 cm. Analysis of variance of all soil moisture measurements showed that average soil
moisture was significantly influenced by days after the planting of the bell pepper plants and
the type of mulch. Upon the analysis of the average soil moisture under various types of
mulch, it was determined that there were considerable statistic differences between sheep and
felt wool in comparison with PE-film and unmulched soil plots. During the growing period,
the highest moisture level was retained in the soil covered with organic wool mulch. With
regard to the results of the research, it is reasonable to recommend using these types of mulch
as an alternative to conventional use of polymers such as PE-film.
