Alfalfa Variety Trial in Graham County, Arizona, 1998

Abstract

Twenty four alfalfa varieties with fall dormancy ratings of 8 or 9 were tested in a replicated small plot trial on a heavy clay loam soil on the Safford Agricultural Center. This was the third year of a new study. CUF JUL only had the heaviest yield in two out of the seven cuttings, but had the highest overall yield for the year at 10.3 tons per acre. Cuf 101 also had the highest average yield over the three years of the study. Heat units with thresholds of 77° F and 40° F are included for each cutting in the study.
