[Yield trial of Alfalfa varieties in Tabriz]
1989
Valizadeh, M. | Khoyi, F.R.
Two selected varieties (Ranger and Hamadani) and three local "varieties" of alfalfa (native-Yondgeh, native-Tabriz and native-Khoy) were compared in a randomized complete block design at experiment station of college for a period of 5 years (1981-1985). Combined analysis, on the basis of dry hay yield, showed that the performance of Karayondgeh and Hamadani was significantly higher than other varieties. The population of weeds was estimated to be more than 50% in majority of plots, after 5 years; however significant differences were not observed between varieties with respect to weed contamination. Furthermore, no interaction between years and varieties was observed while a significant "time of cutting X variety" interaction was obtained. This means that the high yielding varieties can be superior to others all years
