Gr. cv. Lenor in compare earlier registered cultivars Felina and Hykor. The pot experiment was conducted at the Demonstrating and research base of the Department of Grassland Ecosystems and Forage Crops, Slovak Agricultural University in Nitra (Slovak Republic) with controlled moisture conditions (shelter) in 2017. Content of nitrogen, phosphorus, potassium, calcium, magnesium, crude fiber and water soluble carbohydrates were determined from dry above-ground phytomass of grasses. The significantly highest (P<0.05) nitrogen content in average of cuts was in above-ground phytomass of Felina (30.3 g.kg -1 ) than Hykor (25.4 g.kg -1 ) and new intergeneric hybrid Lenor (25.0 g.kg -1 ). At the least content of phosphorus was found out in hybrid Lenor (3.4 g.kg -1 ). In average of three cuts was the least concentration of potassium in new intergeneric hybrid Lenor (5.8 g.kg -1 ). At least content of calcium was found out in hybrid Lenor (7.0 g.kg -1 ). Magnesium concentration of was from 5.0 g.kg -1 (Hykor) to 6.1 g.kg -1 (Felina). Higher (P<0.05) fiber content in average of cuts was in above-ground phytomass of Lenor (27.0 %) and Hykor (26.5%) than Felina (24.0%). The highest concentration of water soluble carbohydrates has in Hykor and Lenor (3.5%). Keywords: grass hybrids, festulolium, quality
Highlights
Festulolium A et Gr. is a natural or synthetic intergeneric hybrid between species of the genus Festuca L. and Lolium L
We watched out 3 cultivars of Festulolium A. et Gr.: 1. Festulolium A. et Gr. cv
Selected qualitative parameters in above-ground phytomass of Festulolium A. et Gr. cultivars are presented in table 2
Summary
Festulolium A et Gr. is a natural or synthetic intergeneric hybrid between species of the genus Festuca L. and Lolium L. Another group consists of so called fescue type (Festuca L.) for example cv. X Festulolium had a broad spectrum uses They are used in animal nutrition in the form of fresh phytomass, or as conserved fodder in the form of hay and silage. Chemical composition and yield value of forage mainly depends on species, levels of soil fertilization, agro-technology, phenological phase, collection technology, conservation and storage (Gálik et al, 2016). The aim of this experiment was to compare selected qualitative parameters of above-ground phytomass of the first Slovak cultivar of Festulolium A. et Gr. with different cultivars
