The optimum harvest time of grass does not cover the same calendar period in each year. In 1998 the best time for the first cut of grass was 7...10 days earlier than in 1997 due to the early spring. In 1998 the optimum harvest time for graminaceous grass was in the last decade of May in Southern and Central Estonia and in the first week of June in Northern Estonia. The optimum harvest time for leguminous grass was in the 2nd and 3rd decade of June. As in spring the protein content of grass, especially of graminaceous, drops and its crude fibre content increases very fast, it would be necessary to fix the optimum harvest time as exactly as possible
