A field trial with four NS alfalfa cultivars was carried out at the Experimental Field of the Institute of Field and Vegetable Crops in Novi Sad, Serbia, during 2005 and 2006. The objective of the study was to determine yields and quality of dry matter in NS alfalfa cultivars as affected by cutting frequency (harvesting frequency). In the more intensive system, plants were cut approximately at the start of flowering, three times in the year of planting and five times in the second year. In the less intensive system, alfalfa was cut twice in the first and four times in the second year (2006). In the plains of Serbia, alfalfa can be cut four or five times a year with no reduction on either yield or stand persistence. The maximum yields and best dry matter quality can be obtained by cutting four or five times a year and planting cultivars with different dormancy (maturation periods). The most dormant NS cultivar is Novosadjanka H-11 and the least dormant (earliest-maturing) one NS Banat ZMS II.
