The beginnings of the red clover crops in our country are not known, after Varga et al (1998), in the middle XIX century the red clover was cultivated in the Romanian Countries, and first recorded information about red clover crops begins in the end of the XVII century. In our country climatic condition and agriculture evolution the red clover production decreased continually, in the 1990 the national production was 1962 thousand tonnes, and in 1453 thousand tonnes ( http://www.insse.ro/cms/files/pdf/ro/cap14.pdf ). In this agricultural context we indented to approach the rentability of an red clover crop used for forage and for seed production for the exploitation during three years. The purpose of this study was carried to test the yield capcity in Verdi red clover variety cultivated in Pecica, Arad County, at PF Zorici on 10 hectares. As a control production was used the national and Arad County average yield, from Romanian Statistical Anuary. The biological material used was represented by Verdy variety cultivated on a hablic chernozem batigleic soil type. The applied technology was the following: winter plowghing, chemical imputs NPK 16-16-16 at 40 kg s.a./ha, seed bed preparation and spring seeding, seed quantity was 20 kg/ha, and 12.5 cm between rows. The total costs from the setting of red clover crop on 10 hectares in 2007 are coming from the costs regarding the mechanical works, material expense that were cost 15.500 lei (Romanian currency). In the first exploitation year was obtained 11.5 t/hay/ha, (three time cuting) and in the second 11.5 t/hay/ha. The total maintenance and production costs for the first production year was 1800 lei, and the production value for the first pexploitation year was 46000 lei (that means 0.4 lei/kg/hay).
