Abstract
Calcium is an extremely important nutrient in highly productive fruit growing such as glasshousegrown sweet pepper. Good bioavailibility of calcium can be achieved by calcisation, but in many cases owing to its high prices, long-term effects, along with a delayed initial effect, as well as problems that appear due to radical change in
availability of other nutrients in soil, its application is restricted. This paper deals with research on effects of foliar applications of the commercial chemical named "Calciogreen", as a supplement to the standard fertilization in greenhouse growing, on yield and quality of pepper fruits of the Cecil cultivar in the region of East Croatia.Kalcij je izrazito važan nutrijent u visokoproduktivnoj povrćarskoj proizvodnji kao što je i staklenička proizvodnja paprike. Dobra bioraspoloživost kalcija može se postići kalcizacijom, ali u mnogim slučajevima njena visoka cijena, višegodišnji efekti uz odloženo početno djelovanje te problemi koji nastaju radikalnom promjenom raspoloživosti drugih hraniva u tlu ograničavaju njenu primjenu. U ovom radu ispitivan je utjecaj folijarne primjene kalcija u obliku komercijalnog preparata "Calciogreen" kao dopuna standardne gnojidbe u stakleničkom uzgoju na prinos i kvalitet plodova paprike sorte Cecil na području istočne Hrvatske
