Abstract
Cilj istraživanja bio je utvrditi prinos zelene mase i suhe tvari engleskog ljulja u uvjetima sjeveroistočne Hrvatske. Istraživanje je provedeno putem poljskog pokusa pokraj Tenje. Engleski ljulj je zasijan 27. rujna 2021., a prinos je utvrđivan u četiri roka (3. svibnja, 8. lipnja, 13. srpnja i 7. rujna 2022.) putem ručne košnje srpom ili kosom. Na temelju provedenog istraživanja može se zaključiti da je ostvareni godišnji prinos suhe tvari engleskog ljulja od 7.352 kg/ha bio nizak, niži negoli u prethodnim istraživanjima drugih autora u raznim dijelovima svijeta. Glavni uzrok niskoga prinosa je u iznimno sušnim prilikama tijekom vegetacije engleskog ljulja, te u rijetkom sklopu usjeva nakon prezimljenja, što je bilo povezano s vrlo niskim prinosom prvoga porasta (samo 910 kg/ha suhe tvari), koji bi uobičajeno trebao biti najprinosniji. Tijekom porasta ljulja nakon prve košnje, ljulj je nabusao i uspio ostvariti zadovoljavajući prinos drugoga porasta od 5.997 kg/ha suhe tvari. Pod pretpostavkom da bi u normalnim uvjetima prinos prvog porasta trebao biti sličan prinosu drugoga porasta (pa čak i veći), engleski ljulj bi unatoč sušnim prilikama ostvario godišnji prinos od oko 13 t/ha suhe tvari, što je više nego zadovoljavajuće u polusušnom klimatu istočne Hrvatske, za krmnu kulturu osjetljvu na sušu, a kakva je engleski ljulj.
Abstract (english)
The goal of the research was to determine the yield of green mass and of dry matter of perennial ryegrass under the conditions of northeastern Croatia. The research was conducted through a field experiment near Tenja. Perennial ryegrass was seeded on September 27, 2021, and the yield was determined in four terms (May 3, June 8, July 13, and September 7, 2022) by hand mowing with a sickle or scythe. Based on the conducted research, it can be concluded that the achieved annual dry matter yield of perennial ryegrass of 7,352 kg/ha was low, lower than in previous researches by other authors in various parts of the world. The main cause of the low yield was extremely dry weather during the growing season of perennial ryegrass, as well as a thin stand of ryegrass crop after overwintering, which was connected with the very low yield of the first spring growth (only 910 kg/ha of dry matter), which should normally be the most productive. During the growth of ryegrass after the first mowing, thanks to tillering, ryegrass managed to achieve a satisfactory yield of the second growth of 5,997 kg/ha of dry matter. Assuming that under normal conditions the yield of the first growth should be similar to the yield of the second growth (and even higher), perennial ryegrass would achieve an annual yield of about 13 t/ha of dry matter despite the dry conditions, what would be more than satisfactory in the semi-arid climate of the East Croatia, for forage crop that is sensitive to drought (what perennial ryegrass is).
