Abstract


The use of fertilizers is an important measure to increase production and improve the quality of feed obtained from temporary grasslands.

If we refer to the mixtures of grasses and perennial fodder legumes studied and to the doses of nitrogen fertilization applied, for a first stage the mixture is highlighted: Medicago sativa 40%.  As a level of nitrogen fertilization, the dose of N120 with fractional application for each harvest cycle and which can give over 6.7 t / ha s.u.
