AB  - Growing grasses in a mixture with legumes leads to more profitable
production, better quality of forages, an increase in soil biogenicity and fixation of
a significant amount of nitrogen. The experiment was established as a two factorial
trial by the method of randomized complete block design in three replications. Italian
ryegrass – monocrop (IR), red clover – monocrop (RC) and their mixtures – IR:RC
(15:5 kg ha-1), IR:RC (15:10 kg ha-1), IR:RC (20:5 kg ha-1) and IR:RC (20:10 kg
ha-1) were planted in November 2016, with the first cutting in the spring 2017 – on
May the 9th, and the second cutting in the early summer – on June the 22nd. The
aim of this study was to investigate the concentrations of phenolic compounds such
as condensed tannins in Italian ryegrass, red clover and their mixtures, as well as
their concentrations impact on protein degradability in the rumen depends on the
seeding rate in the mixtures and harvested in the spring and early summer. Results
obtained in this study showed that higher concentrations of non-protein nitrogen
and soluble protein in forages harvested in the spring influenced higher rapidly
degradable protein concentration in investigated mixtures. The highest rumen
undegradable protein was determined in Italian ryegrass monocrop harvested in
early summer, and we assume that high condensed tannins concentration
influenced the slower protein degradability. Our recommendation for plant
breeders is that cultivars with higher content of condensed tannins should be
created and introduced in animal nutrition.

AB  - The importance of perennial
grasses is multiple. They represent the
basis of sustainable animal husbandry
and the basis of the animal feed industry,
forming the staple food of ruminants in
areas with a moderate climate as
components of natural and sown
grasslands, natural and sown meadows
that can be used through mowing,
haylage and silage.
Adequate and advanced management of
perennial grasses results in low prices of forages, significantly lower than
concentrated feed. Italian ryegrass is
characterized by rapid development and
production of a large amount of quality
forage crops.
The aim of this study was to determine
the content of cell wall components in the
dry matter of Italian ryegrass, as
important indicators of dry matter intake
and digestibility depending on the time of
harvesting and the application of nitrogen
mineral fertilizers.
The experiment was set up at the
experimental field of the Institute for
Forage Crops Kruševac, Serbia,
according to a random block system in
three repetitions. The research results
showed that the highest content of NDF
and ADF was found in the treatment with
90 kg N/ha in the I cut, while the highest
amount of lignin was found in the
treatment with 60 kg N/ha in the II cut.
Based on the obtained values for NDF
and ADF, the results showed that the
highest value for the RFV of Italian
ryegrass in the I cut is in the treatment
without the application of N mineral
fertilizers.
AB  - Значението на многогодишните
треви е многопосочно. Те са в
основата на устойчивото
животновъдство и фуражната
промишленост; основна храна за
преживните животни в райони с
умерен климат; компоненти на
естествени и засети пасища,
естествени и засети ливади, които
могат да се използват за сено, сенаж и
силаж. Правилното управление на
многогодишните треви води до ниски цени на фуражите (значително по-
ниски от тези на концентрираните
фуражи). Италианският райграс се
характеризира с бързо развитие и
продуктивност на голямо количество
качествени фуражни посеви. Целта на
настоящето изследване е да се
определи съдържанието на
компонентите в клетъчните стени в
сухото вещество на италиански
райграс, като важни показатели за
поемането и усвояването на сухото
вещество в зависимост от фазата на
реколтиране и внасянето на азотни
минерални торове. Опитът е заложен в
опитното поле на Институт по фуражни
култури в Крушевац, Сърбия, по
произволна блокова методика в три
повторения. Резултатите от
изследването показват, че с най-
високо съдържание на НДВ и КДВ са
тревостоите третирани с 90 kg N/ha (I
откос), а с най-високо съдържание на
лигнин е фуражната маса третирана с

стойностите за НДВ и КДВ, е
установено, че при италианския

фуражната маса на житната култура от
I откос, във варианта без внасяне на N

AB  - Preservation of genetic variability is very important, especially due to climate change and the need to adapt agricultural production to new conditions. Institute for forage crops Kru{\v{s}}evac keeps a small collection of vetch genotypes (Vicia sativa L. and Vicia vilosa L.). Most genotypes are native to South Australia and the rest originates from Serbia. In Serbia, common vetch is cultivated as a feed for ruminants and can be grown for different purposes as a pure crop or in mixtures with cereals. The quality and yield of vetch green mass is very important for both purposes. A small-plot trial was carried out in 2018 and 2019, at the experimental plot of Institute for forage crops in Kru{\v{s}}evac, Serbia. Twelve promising genotypes of common vetch (Vicia sativa L.) were examined for green forage dry matter yield and green mass quality. The moment of green mass cutting, for each genotype, was at the stage of full flowering and the formation of the first pods. The following parameters of green mass were examined: forage dry matter yield (DMY), crude protein (CP), crude ash (CA), crude fiber (CF), crude fat (CF), as well as acid detergent fiber (ADF), and neutral detergent fiber (NDF). Significant variability was obtained for all tested traits, except for the fat and ash content. Investigations of genetic variability of common vetch can be a basis of further investigations and improvement of new cultivars with desirable characteristics.
