Field trials were designed to identify the most suitable time for the last cut and to ascertain whether it is possible to alleviate the consequences of improper timing of the cut by using the young and old sward under mixed management for forage and seed. Due to the autumn cut of the aftermath, a significant reduction in herbage dry matter yield and metabolizable energy was obtained in the first and second cuts in the following year. The greatest reduction in the seed yield occurred when the autumn aftermath was cut in August and September. When autumn aftermath had been taken annually for four years, the productivity of the sward significantly declined when the cuts had been taken during the August 15 – October 15 period. The most dangerous cutting time, when the greatest yield reduction occurred and the adverse effect of autumn aftermath cutting persisted longest, was found to be mid August – beginning of September. When the sward had been cut during the period mid August - beginning of September, a sharp, significant reduction occurred in the content of total and protein nitrogen, water soluble carbohydrates and starch in roots. When old sward of galega was used under mixed management for forage and seed, the negative effects of autumn aftermath cutting were alleviated or eliminated more rapidly.
