The research was carried out on sod-podzolic sandy loam type of soil in the Kaluga region. Th is article presents the data on productivity and feed quality of Trifolium pratense, Medicago varia, and Galega orientalis in pure (one species) sowings and grass mixtures with Phleum pratense and Festuca pratensis under different ways of sowing.

Keywords: Trifolium pratense, Medicago varia, Galega orientalis, grass mixtures, productivity, crude protein yield.

УДК: 633.31:631.84

Application of starting doses of nitrogen before planting and during the spring regrowth were studied on the herbage of changeable alfalfa on its second and third years of life. It is shown that application of nitrogen up to 60 kg per 1 ha promotes herbage formation in the year of sowing, it does not suppress the formation of nodule bacteria and enhances the general productivity.

Keywords: changeable alfalfa, nitrogen, nodules, herbage, productivity.

Zekić N., Simić A., Vučković S. Eff ect of storage time on bird’s foot trefoil (Lotus corniculatus L.) seed quality

25

Th e commercial bird’s foot trefoil seed (Lotus corniculatus L.) is oft en stored for two or more years. As commercial seed is most oft en kept under uncontrolled conditions, the aim of our researches was to determine seed variability after 2, 5 and 10 years of storage. Th e research was conducted with three recognized Serbian bird’s foot trefoil cultivars which were harvested and stored in 1994. Th e years of storage had signifi cant eff ect on the proportion of germinated, dead and hard seeds. Under uncontrolled conditions the proportion of hard seeds decreased with the storage time and maintained the seed usable for commercial purposes (50 %) until the fi ve year of storage. Th e used cultivars showed significant differences in germination and proportion of hard seeds during the storage time. Bl-17 cultivar had the highest germination after ten years of storage and the lowest proportion of hard seeds. Th e results indicate that the proportion of hard seeds is a cultivar trait which is related to the length of seeds’ viability.

In the zone of dry steppes, agro-phytocenoses of chickpeas with Sudan grass and barley provide sustainable harvesting high-protein weight grass. Th e maximum accumulation of digestible protein in the biomass was allocated by the mixture of chickpeas with barley (4.6 t / ha) and Sudan grass (6.5 t / ha). Th e total yield of digestible protein obtained from chickpea with cereal crops was significantly higher than the regular norms, it amounted to 125–152 gr. per 1 kg.
