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
