Uticaj kalcizacije na proizvodnju krme crvene deteline i italijanskog ljulja gajenih u smeši

This paper examines the influence of liming (control - without CaO; 3t ha-1 CaO) on acidic soil pH of 4.8 to forage, hay yield, the share of red clover, Italian ryegrass and weeds in the total hay yield of mixture crop. The experiment was a set up by randomized complete block design with three replications, with the size of the experimental plots of 5m2 (5x1m). Sowing was done on 20 cm interrow. Soil liming was resulted in a significant increase of yields forage and hay of crops only the first cut in 2012. In all growth during 2011 and 2012, liming is influenced significantly increase the share of Italian ryegrass at the expense of reduction of red clover share, while the share of weeds was not significantly changed. In the third year of production, there was only one growth of red clover, which was very sparse and exhausted, and Italian ryegrass was not. In such conditions, liming is influenced significantly increase the share of red clover at the expense of a significant reduction in the share of weeds.U radu je ispitivan uticaj primene kalcizacije (kontrola – bez CaO; 3t ha-1 CaO) na kiselom zemljištu pH 4,8 na prinos krme, prinos sena, udeo crvene deteline, italijanskog ljulja i korova u ukupnom prinosu sena zdrzuženog useva. Ogled je postavljen po potpuno slučajnom blok sistemu u tri ponavljanja, sa veličinom eksperimentalne parcele od 5m2 (5x1m). Setva je obavljena na međurednom rastojanju od 20cm. Primena kalcizacije značajno je uticala na povećanje prinosa krme i prinosa sena združenog useva jedino u prvom porastu 2012. godine. U svim porastima tokom 2011. i 2012. godine, kalcizacija je uticala na značajno povećanje udela italijanskog ljulja na račun smanjenja udela crvene deteline, dok se udeo korova nije značajno menjao. U trećoj godini proizvodnje, postojao je samo jedan porast crvene deteline, koji je bio jako proređen i iscrpljen, a italijanskog ljulja nije bilo. U takvim uslovima kalcizacija je uticala na značajno povećanje udela crvene deteline na račun značajnog smanjenja udela korova
