Abstract

Pilot studija postavljena je na pokušalištu Agronomskog fakulteta u Maksimiru 2017. godine. Sida je posađena 2017. presadnicama na razmak 0,75 m unutar i između redova na 12 osnovnih parcelica, površine 2,25 x 3,75 = 8,44 m2 (3 reda po 5 biljaka). Cilj rada bio je utvrditi prinos suhe tvari (PST) u jesenskom i proljetnom roku žetve, te broj izboja i visinu biljke na kraju vegetacije druge godine uzgoja side. Prosječna visina biljaka na kraju vegetacije druge godine uzgoja side iznosila je 2,54 m, a raspon prosječnih visina kretao se između 2,30 i 2,85 m. Utvrđeno je prosječno 11,2 izdanaka po posađenoj biljci, odnosno 20 izboja/m2. Prosječni maksimalni prinos ST iznosio je 8,7 t ha-1 uz sadržaj vlage od 35,9 %. Prosječni proljetni prinos ST je iznosio 6,18 t ha-1 uz sadržaj vlage od 13,4 %. Tijekom sušenja nasada side u polju u prirodnim uvjetima došlo je do pada prinosa ST od 29,0 %.

Abstract (english)

The pilot study was set on a testing facility at the Faculty of Agriculture in Maksimir in 2017. Sida was planted by seedlings in 2017. on 12 basic plots 2,25 x 3,75 = 8,44 square meters big (3 rows with 5 plants). The distance between the seedling was 0,75 meters within and between the rows. The goal of the study was to establish harvest of dry matter yield (DMY) in autumn and spring harvest time as well as the number of shoots and height of plant at the end of vegetation of the second year of cultivation. The average height of a plant at the end of vegetation of the second year of sida cultivation was 2,54 meters, and the range of average heights was between 2,30 and 2,85 meters. At average, there were 11,2 shoots on a plant, i. e. 20 on a square meter. The average maximum harvest of DM was 8.7 tons per hectare with moisture of 35.9 %. The average spring harvest of DM was 6.18 tons per hectare with moisture of 13.4 %. During drying of the sida plantation in the field under natural conditions the harvest of DM dropped by 29,0 %.
