There can be appreciated that the land surfaces cultivated with forage plants will increase at least from two reasons, respectivelly the change of the human food structure in the advantage of the animal products and the absolute numeric increase of the humankind, the last one determinng the need of consistent food to be greater. From the forage plants that are distiguished considering the yield and qualitative importance the main are the leguminous. Most of the legumes are excelent forager species, mainly for the ruminants becvause of their increased content in proteins. This content is due to the symbiosis between legumes and bacteria from Rhyzobium genus. The purpose of this study is to approach the rentability of an alfalfa crop used for forage and for seed production for the exploitation during three years. For this purpose there were analysed the costs needed for the setting of the alfalfa field on s surface of 50 hectares on the teritory of the PlantProtection SRL from Siria locality (Arad County) associated with the material expenses generated by the crop maintenance. The biological material used was represented by NS-Banat ZMS II variety cultivated on a vertic faeziom soil type. The applied technology was the following: winter plowghing, seed bed preparation and spring seeding. The total costs from the setting of alfalfa crop on 50 hectares are coming from the costs regarding the mechanical works that were cost 19.750 lei (Romanian currency) and material expenses that were cost 41.250 lei, the total costs being 61.000 lei. From the analysis of the costs regarding the costs for the setting, maintenance and exploitation of the 50 hectares alfalfa crop was obtained 101200 lei for the first exploitation year and 309939 lei for the second. As a conclusion alfalfa crop is one of the most profitable culture for the farmers.
