The study was conducted using various methods such as content analysis, analytical methods, interview and direct observation. In addition, hypothetical-deductive method, statistical methods and descriptive methods were also used. Data were obtained from different sources i.e. the internal documentation of agricultural holding where the quince, as a raw material for production of brandy was produced, the internal documentation of distillery, as well as professional literature and the internet. The analysis was done for the period 2013 - 2016. The study showed that climatic conditions can affect the yield and profitability of quince brandy production, and the production of quince brandy in analyzed years was profitable

It is assumed that the apple orchard establishment on the family farm can contribute to reducing unemployment in rural areas and increasing income of individual farms. As a primary source of information accounting calculations were used, technological table of apple orchard establishment, internal records and the pilot version of the business plan of apple producers at the family farm. For more accurate view and better monitoring of data domestic and foreign literature, internet web sites, available statistical data on the production of apples and publications related to apples production has been used. Methods used for the paper preparation were: calculation of plantation establishment, cash inflows and outflows for the period planned for orchard exploitation, and indicators of economic efficiency. Total cost of planting of apple orchard on the family farm amounts to € 16,080 for one hectare. All economic indicators show positive results. The production is efficient, since the ratio is greater than zero. Planned production is profitable, because profits participate with 71% in total production value. Calculating productivity, it was found that production of one tonne of apples required 822 hours of workers' labour. Establishing apple orchard is certainly high-budget investment, but it can be concluded that the economic effects of raising apple orchards on the farm was economically justified and costeffective, based on the analyzed result.

In order to meet the requirements on the market family farms are obliged to use current resources, raise labor productivity and adapt the production program to the needs of the consumers. Small farms are unlikely to succeed on the market considering the lack of both human and material resources. Their only chance is production intensification, competitive crop production and establishment of associations. The aim of the study was to develop models for different family farm types taking into account the constraints in order to enable an income which would meet the needs of household members. A comparison of the models would enable the determination of competitiveness of some production lines and of the farms involved. This is of principal interest to regions where there are numerous producers disposing of small agricultural land areas and focused on the production of one or two products (raspberry or any other ...

A new epoxy formulation based on the use of polyamine adducts as the hardeners was analyzed. Crosslinking reactions of the different stoichiometric mixtures of the unmodified GY250 epoxy resin with the aliphatic EH606 and the cycloaliphatic EH637 polyamine adducts were studied using mid FT-IR spectroscopic techniques. As the crosslinking proceeded, the primary amine groups in polyamine adduct are converted to secondary and the tertiary amines. The decrease in the IR band intensity of epoxy groups at about 915 cm-1 , as well as at about 3,056 cm-1 , was observed due to process. Mid IR spectral analysis was used to calculate the content of the epoxy groups as a function of crosslinking time and the crosslinking degree of resin. The amount of all the epoxy species was estimated from IR spectra to changes during the crosslinking kinetics of epichlorhydrin.

Within a wide assortment of processed fruit products, there are semi-processed fruit products which can be directly marketed or used as raw materials in further stages of processing, thus causing different economic effects. This paper displays the indicators of economic effects (production value, production costs (especially direct costs), and the difference between production value and total production costs) in all stages of a certain type of fruit processing. The obtained results indicate that advanced stages of fruit processing entail an increase in costs, but these increased costs eventually enable higher revenues. Fruit processing is cost-effective due to the fact that fruit processing value is higher than the market value of fruits. The fruit processing value in compote production is on average 48.87% higher than the fruit market value. In semi-processe...

Volatility in agricultural production caused by the reliance on natural factors, and water is one of the basic, which provides greater production. The authors in their professional praxis have seen that the presence and absence of vadose zone in the upper part of aquifer, with inter-granulary porosity type, is a prerequisite for enhanced concentrations of iron and manganese in groundwater. The natural aeration zone in vadose zone of the upper part of aquifer enables additional enrichment of groundwater with oxygen, which is spent on the account of biochemical processes in the direction of their flow. The absence of this zone in aquifer directly influences higher iron and manganese content in groundwater, often above the permissible concentration in drinking water. In order to eliminate this problem, in this paper proposal of future works ...

Total area under fish farms in Serbia amounts to approximately 11 thousand hectares, with 8.5 thousand hectares being under exploitation each year. In 2004, a significant intensification of production began at fish farms in Serbia which have traditionally organized their production under a classic semi-intensive farming system. Intensification of production was undertaken with partial or complete feeding with pelleted complete feeds. That way carp production per area unit (kg/ha) was increased by over 50%. Apart from intensification by means of using the complete extruded feeds, construction of specialized fish farms for intensive carp production started in 2003. At this moment (2016) their area amounts to several hundred hectares. Data from intensive carp fish farms indicate that production of one-and two-year fish has been approximately 3t/ha in the period from 2003 until today, with a mild increase during the last couple of years. With the purpose of determining the cost effectiveness of investments in fish ponds for intensive carp production two organization-economic models have been analyzed in the study. The models have been formed based on in line with the specific features of the Serbian carp farming, which has been analyzed both on the basis of data obtained from the scientific and specialist literature but also from the production practice. Models of intensive carp production in technical and production sense have been defined in the study and production plans have been prepared. Therefore, based on such defined models,

This study required the use of different methods and techniques such as: content analysis, case study, observation, testing and systemic approach. The study showed that sale of the Imlek Company products was widespread in the country and the region. An ongoing market advantage is achieved due to a high quality standard of products, and primarily due to an effective management of human resources. Company management should make formalisation and unification, and implement a set of measures in order to improve discipline of the employees. Top workers should be motivated through incentives for performance and innovation.

Investigation of correlation between slaughter traits of pigs fed with different additives in their nutrition was done by factorial analysis. Slaughter characteristics in three groups of fattening pigs fed in different ways were observed. The first group (variant 1) consisted of fatteners fed diets without any special additives. The second group (variant 2) consisted of pigs fed diets containing enzyme Rovabio, and the third group (variant 3) probiotic Lacture + Microbond. This study was aimed at coming to conclusion based on the results of factorial analysis of the observed traits to the greatest extent which determined slaughter traits of pigs fed diets containing different additives. The results obtained in general, that is, the structure of separated factors showed that different slaughter characteristics are realized with different nutrition.

Emphasis is placed on explaining the connections and relationships between organizational, economic, technical and technological business segments of family farm. The ultimate goal of this paper is to evaluate the strengths of the business, as well as the ways to eliminate or reduce the impact of those factors whose influence adversely affects the business. The data for this paper were collected from family farm business reports, throughout direct communication with employees, from relevant literature and internet. Several methods were applied, including: a method for content analysis, calculative and balance methods, spreadsheets, as well as method of comparative analysis and principles of business economics. Key success indicators of beef cattle production on the family farm suggest that, considering both observed years, the business achieved satisfactory results. Although there was a decline in productivity, total efficiency measured by the ratio of total income and total expenditure is on an uptrend. An investment turnover ratio show that 100 RSD invested in the production achieves 63 RSD of final product value in 2011, or 55 RSD in 2012. In both years, current assets covered the current liabilities. The family farm was not solvent in either of the observed years, except that in 2012 the solvency increased by 42% compared to the previous year, 2011. Total debt increased by 45%, whereas total operating assets increased by 106%. Based on the obtained results it can be concluded that the observed family farm provides a good example of how organized and proper process technologies of cattle production may improve the achieved business results.

Several methods were applied, including: a method for content analysis, calculative and balance methods, spreadsheets, as well as method of comparative analysis and principles of business economics. Key success indicators of beef cattle production on the family farm suggest that, considering both observed years, the business achieved satisfactory results. Although there was a decline in productivity, total efficiency measured by the ratio of total income and total expenditure is on an uptrend. An investment turnover ratio show that 100 RSD invested in the production achieves 63 RSD of final product value in 2011, or 55 RSD in 2012. In both years, current assets covered the current liabilities. The family farm was not solvent in either of the observed years, except that in 2012 the solvency increased by 42% compared to the previous year, 2011. Total debt increased by 45%, whereas total operating assets increased by 106%. Based on the obtained results it can be concluded that the observed family farm provides a good example of how organized and proper process technologies of cattle production may improve the achieved business results.
