The current tendency is for intensification of livestock farming, pursuing continuous improvement of quantitative and qualitative performance of products. Intensification of meadows can be achieved through the use of valuable species, highly productive varieties of perennial grasses and legumes, by cultivating perennial grasses and legumes in mixtures and by proper management of meadows. Unlike pure cultures, mixing alfalfa with orchard grass provides a more balanced energy-protein feed, while providing the opportunity of ensiling alfalfa in good condition due to the contribution of soluble carbohydrates provided by the orchard grass. The purpose of this research was the capitalization of pure-crop alfalfa and mixed crop of alfalfa with orchard grass as succulent fodder packed in bales. Objectives and activities are represented by quantifying the quantitative elements which express the quantitative value, as well as the elements which express the qualitative value of fodder. The highest average yields achieved over three years, for all three mixtures tested, were obtained by fertilizing with N100P50 kg ha‑1. The quality of the fodder was influenced by the proportions of the two species in the mixture and by the level of fertilisation.
