Alfalfa seed coating consists of coating the seed with a mixture of rhizobia, a fungicide or an insecticide, calcium carbonate and a binding substance. The aim of the study was to compare seed coat percentages (10%, 20%, 30%, 50% and 75%) and naked seed in relation to established plants and forage yield. Following a design with 3 reps, a trial was established in 2013 at 10 kg per ha in which the number of plants per m² was studied by counting at different days of sowing and at the end of the first season and forage yield. Up to 17 and 29 days after sowing the number of plants per m² was higher in the two naked seed treatments. After 46 days of sowing, the treatments with the lowest seed coating percentage showed the highest numbers of plants per m². High seed coating percentages (30%, 50% and 75%) had the lowest number of plants per m². The highest forage yields were obtained with low seed coating percentages and naked seed treatments. By contrast, seeds with 75% coating treatment exhibited the lowest accumulated forage yield and one of the lowest values of number of plants per m² at the end of the season.
