Set on a Festuca rubra - Agrostis capillaris (Agrostis tenuis) grassland, at a height of 628 m in the MaramureÈ™ Depression, the experiment was carried out by means of the randomized blocks method. We performed a bifactorial experiment with factor A as the amendment, and factor B the level of fertilization.As a result of fertilization throughout the study period using different doses in accordance with the experiment protocol, improvements were observed from one year to the next. The yield grew significantly on the fertilized variants compared to the witness lots, as seen in the dry matter content. The best results were obtained in the organic-mineral fertilized variants.Keeping in mind resource preservation, environment protection and biodiversity conservation, a good strategy regarding these ecological and economic concerns is the use of organic fertilizers on permanent grasslands. Concerning yield growth, the most effective method is the use of mineral and organic-mineral fertilization.The paper presents the evolution in time of the annual forage production, while data about the floristic composition will be presented in a future paper.
