Forage yields in urban populations of hairy vetch (Vicia villosa Roth) from Serbia

摘要

Hairy vetch (Vicia villosa Roth) is widely distributed in Serbia and often grows in diverse environments, including urban areas. A small-plot trial was carried out in 2006 and 2007 at the Experimental Field of the Institute of Field and Vegetable Crops at Rimski Sancevi. It included seven hairy vetch populations collected from several urban regions of Belgrade and Novi Sad. All seven populations were sown in early October, at a rate of 180 viable seeds m~(-2), and cut at the stages of full floweringand formation of the first pods. With an average crop density before cutting of 150 plants m~(-2), the populations MM 04/13 and MM 04/18 proved to be the most winter hardy. The average values of plant height ranged from 100 cm in MM/04/20 to 235 cm in MM03/26. The population MM 03/26 had the greatest numbers of both stems and lateral branches (15.0 plant~(-1)) and internodes (163.0 plant~(-1)). The highest green forage and forage dry matter yields were in the population MM 04/19 (50.9 Mg ha~(-1) and 11.7 Mg ha~(-1)). The highest proportion of forage dry matter was in MM 04/09 (0.33).
