Description
Thirty-five cultivars of alfalfa were evaluated at EE de Zootecnia in Sertãozinho,SP, Brazil. During four years, the plants were harvested to determine dry matter yield on total and individual cuts. A completely randomized block design with three replications was used, and data were analyzed by groups of origin and dormancy degree. There were significant differences (P< 0.05) among the cultivars regarding their dormancy degree, however no differences (P> 0.05) were observed regarding their origin. Cultivars with 8 and 9 dormancy degree showed better performance during the four year trial when compared to 7 degree, although some of the 9 degree cultivars resulted in low yield. The origin of cultivars did not influence yield, but the Argentinean group, although not significantly, showed a slightly higher yield when compared to other cultivars.
