Methanotrophy is a biological process that effectively reduces global methane emissions by utilizing microorganisms can utilize as source of energy under both oxic and anoxic conditions, using variety different electron acceptors. Methanotrophic microbes, which their primary carbon energy, are found in various environments, such soil, sediments, freshwater, marine ecosystems. These microbes play significant role the cycle consuming methane, potent greenhouse gas, converting it into dioxide,...

During post-harvest maturation, different species vary in the length of dormancy breaking or germination increases. Seed and slow seedling development often limit establishment forage grass stands. vigour Italian ryegrass (Lolium italicum A. Braun, Synonym Lolium multiflorum L.), cocksfoot (Dactylis glomerata L.) timothy (Phleum pretense were observed after harvest storage. After June, seeds stored under standard storage conditions sampled every 30 days (DAH), up to 270 DAH, then 60 990 DAH....

Considering the interest in consumption of faba bean and study antioxidants natural food resources, methanol extracts fourteen Vicia cultivars harvested from a two-year field experiment were studied for their phenolic compounds, proanthocyanidines, antioxidant activities by DPPH free radical scavenging assay, ABTS cation decolorization ferric reducing power (FRAP), cupric capacity (CUPRAC), total (TRP). The results indicate significant differences among populations content polyphenols...

After-ripening is a complex enzymatic and biochemical process resulting in the breakage of non-deep physiological dormancy. The experiment was set up to identify minimum duration storage after harvest for completion afterripening meadow (Festuca pratensis Huds.), tall arundinacea Schreb.) red fescue rubra L.). seeds were stored under ware-house conditions 0, 30, 60, 90, 120, 150, 180, 210 240 days (DAH). After periods, tested germination primary root length, shoot length seedlings biomass...

This study presents the findings from assessing quality of alfalfa seeds collected three Serbian regions: in each region, batches six places were analyzed. The following criteria investigated: proportion dormant seeds, germinated seed content, dead and percentage aberrant seedlings. Seed was assessed after six, eighteen, thirty, forty-two months storage. highest obtained thirty eighteen storage (91% 89% germination, respectively). During 42-month period, (8%) abnormal seedlings (7%)...

The objectives of this work were to determine whether and at which seed physiological maturity stage the diquat desiccant affects tall oat-grass (Arrhenatherum elatius) quality yield, as well proper storage period between harvest sowing. Diquat desiccation was evaluated in applications during milk or dough maturation stages. Seeds conventionally produced stored under traditional conditions used for analyses. Seed samples drawn every 30th day after (DAH). After 240th DAH, 90th up 690th DAH....

Tall fescue (Festuca arundinacea Schreb.),red rubra L.) and cocksfoot (Dactylis glomerata are important fodder grasses, but in seed production, they prone to shedding certain yield losses.In practice, seeds usually harvested at approximately 20-35% moisture content then additionally dried the of 12% or lower.However, prevent shedding, was 45% content.The effects drying temperatures 70, 60, 50, 40, 30 22 °C on germination dormancy tall fescue, red seeds, contents 45, 35 25 %, were observed...

Tests of seed germination, dormancy and seedling growth were performed on 0-, 6-, 20- 30-months-old lots Festulolium in comparison with Italian ryegrass (Lolium multiflorum) meadow fescue (Festuca pratensis). seeds harvested 2 different years (2014 2015) resulting no major difference between the years. Seed storage affected viability all 3 grasses. The maximum germination was achieved 6 months after harvest (95% normal seedlings); decreased significantly thereafter. While L. multiflorum F....

In the past few years in Europe grass seed production declines. This tendency is especially pronounced meadow fescue. Seed shedding and therefore yield losses are problem production. can be reduced if of higher moisture contents harvested. The impacts drying temperatures 70, 60, 50, 40 22°C on changes dormancy germination harvested with 45, 35 25% were observed present study. analysis was done immediately after drying, then three months later eight later. Seeds content 45% that dried at 70°C...

In addition to normal seeds, hard seeds of alfalfa have often been found after harvest. Such prevent the penetration water and gases into seed interior, causing reduction in germination. They do not tend germinate even under ideal laboratory or field conditions, they exhibit late Consequently, are no relevance planting crops. A decrease amount an increase germination can be achieved by scarification acids, physical damage coat, hot water, cooling, etc. Temperature treatment prior sowing is a...

The aim of this paper was to evaluate the agronomic value red clover (Trifolium pratense L.) wild populations. analyzed material gathered on territory Serbia and it estimated which populations could be involved in breeding program. 17 were included research. Investigation carried out at experimental field Institute for forage crops, Krusevac, Serbia. trial performed during three years (2008 - 2010) when data about morphological (green mass, dry mater, plant height, number stems, lateral...

In agricultural production, pests and diseases of crops, as well weed plants, cause significant losses in the yield quality products. One most effective ways fighting is use a wide range chemicals called pesticides. accordance with EU Directives 2009/128/EC 2006/42/EC underlying standard EN 13790, Plant Protection Administration Ministry Agriculture Environment Republic Serbia has established framework for control sprayers mist blowers. Maintaining pesticide application good state repair...

The paper presents the results of four seed lots produced in Serbia and Belarus two years, examines influence their quality on 1000 mass, germination energy total germination. There was no impact region or year studied parameters. high variability mass (CV = 20.3 %) taken from different Italian ryegrass. Lower found for 9.88 % CV 7.98 %). Ryegrass had lower 8.34 %), 4.80 3.70 In seeds both species there significant correlation dependence regarding Significant determined between (P≤0.001 P≤0.05).

The effect of cultivar and plant density on dry matter yield nutritive value alfalfa was studied. trial conducted at the first cutting plants in their second third years growth, four cultivars two different crop densities were tested. found to have significant yield, proportion leaf total content crude proteins under both densities. highest forage achieved (20 cm row spacing with 15 kgha-1 seed rate). wide (50 cm) low rate (9 kgha-1) showed lower production. other parameters insignificant. A...

Timothy grass is a fodder mostly grown as pure stand or in mixed stands with legumes at higher elevations. It cultivated for its high yields and the supreme quality of roughage containing grass. There are different methods preserving seed grasses relative to following parameters: species, variety, harvest methods, postharvest treatments, well storage temperature air humidity. Poor germination often caused by presence dormant seeds which fail germinate despite ideal conditions field...

This paper presents the results of cleaning tests three different natural alfalfa seed lots and red clover performed using processing machines. The (Medicago sativa L.) (Trifolium pratense are two most important perennial forage legumes in Republic Serbia. Alfalfa seeds for sowing should be clean, i.e. free from weeds foreign matter, high germination genetic values. Such requirements can only achieved by cleaning, removing all undesirable impurities poor-quality seeds. following parameters...

In Serbia, alfalfa is the most important perennial forage legume that grown at 180-200 thousand hectares. Except for classic production of forage, very seed production. our conditions Alfalfa are produced from second cut alfalfa. Higher yields achieved in larger distances between rows. this system first and third used fodder. This trial tests three different densities four varieties order to determine impact on yield quality dry matter. year establishment, cultivars treatment A1 higher...
