      Aldura, Westbred Turbo and Westbred 881 were grown in four sites in three counties (Graham, Greenlee and Cochise) in southeastern Arizona to determine which would produce the largest income per acre. At an assumed 75 cent premium for Westbred 881 over a base of $5.25 per hundredweight, Aldura and Westbred Turbo generally out produced Westbred 881. Relative yields of the three varieties are shown for all locations.

      A field study was carried out to determine the effects of different fertilizers on yield and quality of alfalfa. Two harvests over a period of four cuttings did not reveal any differences due to treatment. While alfalfa often responds to phosphorus (P) fertilizer application, conditions in this study provided adequate P as well as nitrogen (N) and potassium (K).
