Influence of different soil tillage on yields of winter wheat and barley

Cilj rada bio je utvrditi utjecaj različitih sustava obrade tla (oranje, podrivanje i tanjuranje) na prinos ozime pšenice i ječma. Istraživanjem je utvrđeno kako se uz pravilnu agrotehniku može postići jednak ili veći prinos istraživanih kultura koristeći različite sustave obrade tla. U 2020./2021. vegetacijskoj godini utvrđeni su iznimno povoljni agroekološki i agrotehnički uvjeti za rast i razvoj usjeva, dok su ozimom pivarskom ječmu uslijed nepovoljnih temperatura oštećeni listovi (izmrzavanje). Nakon provedene prihrane dušikom (KAN) ozimi pivarski ječam se u potpunosti oporavio i ostvario prosječne prinose: Planet (9,9 t/ha) i SY Tepee (9,1 t/ha). Ova vegetacijska godina nije pogodovala razvoju bolesti i štetnika te nisu uočene značajnije štete na istraživanim usjevima. "PO Kalac" se bavi poljoprivredom kao primarnom djelatnosti od 1999.g. pa sve do danas. Ukupna proizvodna površina na PO Kalac iznosi 200 ha od kojih su 80 ha pšenica i ječam.Objective of thesis was to investigate the influence of different tillage systems on the yield of winter wheat and barley, and all the necessary conditions for the cultivation of winter wheat and barley. Research has shown that with proper soil tillage techniques can achieve the same or higher yields of the studied crops using different tillage systems. In this vegetation year, precipitation met the conditions of the crop, while in winter brewing barley, unfavourable temperatures were followed by damaged leaves (freezing). After nitrogen fertilization (KAN), winter malting barley fully recovered and achieved an average yield: Planet (9.9 t / ha) and SY Tepee (9.1 t / ha). This vegetation year did not favour for the development of diseases and pests, and no significant damage was observed. "PO Kalac" has been engaged in agriculture as its primary activity since 1999. until today. The total production area at PO Kalac is 200 ha, of which 80 ha are wheat and barley
