Krmni ohrovt (Brassica oleracea L. convar. acephala (DC.) Alef) ; Kale (Brassica oleracea L. convar. acephala (DC.) Alef)

Krmni ohrovt je s hranili bogata krmna rastlina, ki zaradi tehnoloških omejitev pri pridelovanju in vsebnostih škodljivih sestavin, v praksi ni močno razširjen. V diplomskem delu je strnjen pregled obstoječe strokovne literature o krmnem ohrovtu v Sloveniji in predstavljen poljski mikro poskus, izveden v naključnih blokih v štirih ponovitvah, na kmetiji Rojko v Spodnjem Dupleku (Vzhodna Slovenija). V poskusu je bil preučevan vpliv roka setve krmnega ohrovta strženarja (Brassica oleracea L. convar. acephala (DC.) Alef. var. medullosa Thell) sorte Zeleni Angeliter, na višino rastlin, delež listov in prezimitev. Najvišjo končno višino so meseca novembra dosegle rastline, sejane meseca marca (210 cm), najnižjo pa rastline, sejane v mesecu juliju (100 cm). Najvišji delež listov v pridelku je bil pri setvah v juliju (40,7 %), najnižji pa pri setvah v marcu (20,1 %). Prezimitev rastlin pri nobenem izmed rokov setve ni bila uspešna. Zaradi uporabnosti listov za krmo so za jesensko uporabo primerne setve v mesecu juliju in avgustu. ; Although kale is a rich and nutritious plant, it is not a wide-spread fodder in everyday practice, due to its technological limitations in production and its harmful substances. The thesis presents a concise overview of available specialized literature on kale in Slovenia and a micro field experiment carried out with random blocks in 4 repetitions on the Rojko farm in Spodnji Duplek (Eastern Slovenia). The experiment determined the effects of seeding time of marrowstem kale (Brassica oleracea L. convar. acephala (DC.) Alef. var. medullosa Thell), Green Angeliter, on the height of the plants, the proportion of leaves in yield and wintering. The plants seeded in March reached the maximum height (210 cm) while the plants seeded in July reached the minimum height (100 cm). Plants seeded in July had the highest proportion of leaves (40,7 %), and those seeded in March had the lowest (20,1 %). Wintering of the plants was unsuccessful in all cases. The most appropriate sowing time is in July and ...
