Alfalfa Productivity and Quality.

Finding a suitable and profitable alfalfa forage that matches the demands of the livestock feeder and the alfalfa grower is important. For many years now it has been common for research to be done on corn and soybeans throughout the Corn Belt, however, it does not seem common to find many comparisons and research on alfalfa varieties. In order to get an insight of how different varieties of alfalfa perform in Nebraska five varieties of alfalfa were selected. The selected varieties were based on unique, individual and shared characteristics that the varieties possess. The five verities selected were Geneva (Syngenta), Evergreen 2(Syngenta), Rainier(Syngenta), Vernal (Mustang Seeds), and Pro Fast (Producers Hybrids). The five varieties were planted in the spring of 2004. This year the crop is now established. The varieties were drilled in two separate plot locations. The plots alternate differently among each plot incase of a variety having an effect on a neighboring variety. The plots are each 1 acre, for a total of 2 acres per variety. This is a long term research project since alfalfa is a perennial that requires several years of observations and measurements to get an insight of a particular variety's performance. Observations and measurements include: noting visual characteristics such as: leaf and stem qualities, insect resistances, and hardiness. Measurements will be made based on re-growth, yield, dry down rates, and forage feed values such as crude protein, moisture and relative feed value. After performing research on these alfalfa plots, comparisons will be made in order to make any observations in significant differences. These differences will be noted as to which observations made are favorable to alfalfa production in Nebraska.
