The aim of the methodology is to characterize the optimal methods of harvesting and ensiling peas, broad beans and yellow lupine. Selected types of legumes were grown on the plots of the VÚŽV purpose-built farm in Prague-Uhříněves in the two growing seasons of 2022 and 2023. Broad beans (Merkur variety), field peas (Gambit variety) and yellow lupine (Salut variety) were compared. During the growing season, forage from each crop was collected at the growth stages: 1) full flower, 2) end of flowering, 3) seed filling and 4) full seeds, or waxy maturity. Beans were the best crop in terms of yield, nitrogen content and digestibility, and therefore for fodder and silage use. According to the dry matter content with regard to further loading, peas are a more advantageous crop for silage use. Yellow lupine failed to reach the yield or quality parameters of beans or peas. From the point of view of the harvest date, in general, for all tested leguminous species, the most advantageous harvest is at the time of seed filling. A later harvest already provides lower yields of nitrogenous substances and digestibility of nutrients in beans and lupins.
