The Italian ryegrass (Lolium multiflorum Lam.) provide a large amount of feed per surface unit due to its high productivity. Due to its wide use, a number of varieties are found on the market, the farmer being put in the situation to choose between those varieties that best meet the needs of his own farm. In this context, the paper aims to evaluate the production capacity at anthesis and the content of feed in protein and fiber in two vegetation phenophases in three varieties of Italian ryegrass. Three varieties were used as biological material; two tetraploids (Linos and Ivan) and one diploid variety (Sprint), grown under the conditions of Agricultural Research and Development Station Lovrin, Romania. According to the research, the tetraploid varieties Linos and Ivan are more productive than the diploid variety Sprint. The Linos variety behaved the best, which in the anthesis phenophase (BBCH65) recorded a production of 92 t.ha-1, with the feed containing 8.7 % protein and 36 % fiber. Regarding the protein and fiber content, the varieties analyzed are grouped according to the harvesting phase: BBCH49 and BBCH65. The highest content in the protein was found in the BBCH49 phenophase and decreased in the BBCH65 phenophase as the fiber content increased. These results can be useful for the farmer in making decisions on the choice of varieties of Lolium multiflorum Lam. and the harvest period.

Bird's-foot trefoil ensures the perennity of the meadows arranged vertically altitudinal and contributes to their sustainable use. For the establishment of sown meadows and oversowing of permanent grasslands, valuable Bird's-foot trefoil varieties are needed, adapted to the climatic conditions of the area and with high production potential. The present paper is part of such an approach and aims to evaluate a collection of 16 forms of Bird's-foot trefoil, representing a diverse range of agronomic types, in terms of morphological parameters regarding the production of seeds at the Bird's-foot trefoil and the yield of fresh fodder and dry matter. The research was conducted between 2020-2022 in the natural framework provided by the experimental field of ARDS Lovrin. The results of this study indicate that based on the functional relationships between morphological parameters, the 16 forms of Bird's-foot trefoil studied are divided into three large groups. For the production of the seeds, the forms of the Lv10, and Lv 15 Bird's-foot trefoil proved valuable, which showed a large number of generative shoots. In this regard, these forms of Bird's-foot trefoil can be tested alongside the Lv13 and LV8 genotypes. The highest yield was registered in the genotype Lv1 Bird's-foot trefoil, which achieved a fresh fodder yield of 19 t.ha-1 and a production of 4.39 t.ha-1 dry matter, highly above the average of the experiment. Value for selection shows six more genotypes of Bird's-foot trefoil that exceed the average of the experiment. This research is a basis for improving and selecting valuable, stable genotypes for future cultivation.
