Animal husbandry is the most important branch of agriculture because it produces food for people. Forage plants, grasslands and pastures are a cheap high-quality source animals. They create large vegetative mass rich in proteins, carbohydrates other nutrients. The climatic condition Serbia favorable forage production crops. crop structure on arable land very unfavorable, primarily from aspect animal feed sustainable use. trend decreasing areas under meadows coincides with numbers all types...

Understanding the complex relationships between soil fertility, crop productivity, and management systems in agriculture would contribute to developing sustainable systems. The paper analyzed possibility production with reduced fertilization by comparing traditional mineral fertilizer application no-fertilizer field experiment was carried out 2017-2019 central Serbia on eutric cambisol. alfalfa variety K-28 set up according a completely randomized block system 3 replications. following...

Legumes can make a very significant contribution to sustainable crop production systems. Red clover (Trifolium pratense L.) has potential production, due its impact on increasing soil fertility. It is characterized by high biomass yields of excellent quality, protein content and degree nitrogen fixation. Since the middle last century, area under red been constantly decreasing globally, mainly cheap synthetic fertilizers. However, interest in growing this legume growing, increase price...

A sufficient supply of potassium in plants is important for the processes photosynthesis, carbon dioxide assimilation, movement, carbohydrate metabolism, enzyme activity, maintenance water balance and other plant. Potassium an element growth development, especially formation, ripening fruits. The aim study was to analyze importance forage legumes achieving high high-quality yields seed. lack such as alfalfa, clover, soya beans, cowpea lupine leads weaker nodulation, which has a negative...

In this study, the effect of NPK fertilization with different nitrogen rates on dry matter yield and botanical composition a Festucetum pratense natural grassland was analysed in 10-year field trial. The experiment conducted period 2011–2020 central Serbia, 1000 m above sea level. fertiliser treatments included: control without fertilisers, N60:P40:K40, N100:P40:K40, N140:P40:K40 kg/ha per year. mineral fertilisation had significant grassland, especially first cut, resulting lower total...

In the current intensive systems of agricultural production, many important features, i.e., functions agroecosystem have been degraded and disrupted. The intensification production inevitably leads to land degradation in terms its physical, chemical, biological properties. increasing presence monocultures, reduced crop rotation, excessive use mineral nutrients, lead several negative phenomena such agroecosystems. Along with efforts reduce energy consumption, environmental pollution,...

Alfalfa silage has a high potential for improving ruminant nutrition. A problem that frequently occurs during its preparation is the process of proteolysis, which could partially be avoided with use certain techniques and materials. Red clover, often used in form silage, expresses weaker proteolysis due to possession chemical compounds. This research was conducted study effects ensiled alfalfa red clover mixtures, mixed at different ratios (100:0, 90:10, 70:30, 50:50, 30:70, 0:100), as well...

A prerequisite for the improvement of birdsfoot trefoilproduction is productionof sufficient quantities good quality seeds. The aim study was to analyzethe impact seed inoculation with mesorhizobial bacteria on yield and yieldcomponents trefoil (Lotus corniculatus L. ). In experimentbirdsfoot cultivars Zora, K-37 Rocco, two strains Mesorhizobiumloti were used. trial carried out in spring 2012 a private estate thevillage Ivanovci near Ljig (Serbia) set up brown forest soil type,using...

NDF is a good indicator of fiber content in forages, but on the other hand digestibility gives more accurate estimates total igestible nutrients. The aim this study was to evaluate two red clover cultivars for and DM depending stage development – mid bud stage, early bloom bloom, harvesting three different cuts. Results showed that lignin increased with plant maturation all highest determined third cut ranged from 5.87 5.92% 5.56 6.53% K 39 32 cultivars. Intensive lignifications cell wall...

The work aimed was to analyze the importance and possibilities of using cobalt for fertilizing annual forage legumes. Cobalt in small concentrations soil has a positive effect on processes nodulation symbiotic nitrogen fixation. Therefore, its addition as fertilizer, especially acidic soils, growth, yield, quality leguminous plants. Optimum solution vary depending plant species range from 8 50 ppm. Higher most legumes result toxic effect.

A major problem when establishing alfalfa crops can be the presence of weeds. In intensive systems, weeds are controlled with herbicides, which inevitably contaminate water, soil, air, and food. The work aimed to carry out a comparative analysis between system cultivation herbicide use method without in order able make recommendations for development sustainable management systems agriculture. field trial was conducted at experimental Institute Animal Husbandry, Zemun, Serbia, using...

The production and utilization of intercropped legume- cereal bi-crops as ruminant feeds is beneficial for many reasons – legumes are rich in terms protein concentration, whereas cereals characterized by higher carbohydrate contents. To improve common vetch-oat mixtures feed Serbia, the objective this investigation was to evaluate crude (CP) (CHO) fractions these using Cornell Net Carbohydrate Protein System (CNCPS) depending on stage plant development seeding rate vetch oat mixtures....

The growth and metabolism of plants, especially on acidic soils, largely depend the concentration cobalt (Co) in soil, i.e. rhizosphere. An optimal supply is essential for N2 fixation Rhizobium bacteria that are symbiotic relationships with leguminous influencing their better supplying them nitrogen. When there a lack Co plant, organic production legumes falls. Indirectly or directly, also affects other metabolic processes plants. aim work was to analyze importance provision forage obtaining...

This study was carried out in the Bucegi Natural Park, a protected area of Romanian Carpathians. It aims at documenting potential sensitivity six widespread Natura 2000 habitat types and all plants with conservative value (200 taxa) mountain area, to changes temperature humidity, predicted for this century. Regional expert knowledge environmental indicator values were considered assessing habitat’s sensitivity. The results support evidence that may be potentially higher habitats alpine...

Natural grasslands are major animal feed resources in the moutainous region of Serbia. Proper use mineral fertilizers these can lead to a multiple increase productivity. The paper analyzes effect NPK with different levels nitrogen (unfertilized - A0; N60:P40:K40 A1; N100:P40:K40 A2; N140:P40:K40 A3) on forage yield and botanical composition natural grassland Arrhenatheretalia order slopes Mount Kopaonik. With amount applied spring from 40 80 kg ha-1, hay yields also increased, whereas...
