Koniczyna czerwona wyżej plonowała w porównaniu do życicy wielokwiatowej w siewie czystym i jej mieszanki z tą trawą. Natomiast plonowanie mieszanek, do których komponent trawiasty byt wprowadzany metodą podsiewu, było nieznacznie wyższe w porównaniu do koniczyny w uprawie indywidualnej. Koniczyna czerwona wytworzyła w każdym pokosie większy indeks liściowy niż życica. We wszystkich pokosach życica miała wysoką zawartość włókna.

The paper presents the results from the period of three years (1992-1994) of experiments describing purpose fulness of under so wing the Italian ryegrass (12 kg/ha) into already growing red clover which was previously undersown into spring bailey. Undersowing was done at three different dales; after harvesting the barley as green forage tit the earing stage — IV. after harvest of barley for grain — at the stage of full maturity — V, and in the second half of september — VI. Comparison plots were: red clover — I, Italian ryegrass — II, and the mixture of two above III seeded in the spring. Effectiveness of undersowing of Italian ryegrass was relatively low measured by the percentage of its share in the mixture with red clover, and was respectively in first cutting; IV - 18%, V — 6% and VI — as compared with 41% in the mixture — III. Regardless form the method of sowing the yields of mixtures of red clover with Italian ryegrass (III- IV) were higher than the yields or Italian ryegrass grown alone II. The yields od red clover grown alone were similar to its mixtures with Italian ryegrass. Higher protein and fat content in red clover as compared with ryegrass justices the growing of this grass in mixtures with red clover. Leaf index of red clover stand was higher that the one of Italian ryegrass for all cuttings.
