Effects of direct fertilization on lucerne (Medicago sativa L.)forage yield have been widely investigated;however there is a lack published studies investigating the long-term effect indirect application mineral and organic fertilization. The main objective present research was therefore to investigate differences in forage under different combinations (6 treatments) (3 over past 8 years experiment conducted since 1955 Ruzyně.Long-term absence provided average annual dry matter 8.64 t/ha. Indirect single manure or slurry significantly increased 9.68 9.37 t/ha, respectively. Absence 9.23 t/ha across an inconsistent increase indirectly applied nitrogen (N) rate observed. highest yields 10 were observed at treatments where with higher rates N, phosphorus (P) potassium (K) applied. trend for reduction increasing N within identical P K This has shown that should be considered together stand age when evaluated.
