Analyzing consumers’ opinion on organic food, their safety and availability in the slovak food market

oai:ojs.potravinarstvo.com:article/16In our paper we focus on the consumers´ opinion on bio - food, their safety and availability in the Slovak food market. The analysis is based on a survey organized in the period between December 2009 and January 2010. From the methodological aspect, basic approaches of descriptive statistics have been used, as well as methods of association measurement. The test of robustness tested Chi-Square statistic. The robustness have been judged based on the p-values. Correlations have been tested through the Contingency coefficient and Cramer's V coefficient. From the survey it can be concluded that even though consumers have some idea about bio – food and trust them more compared to other conventional food, they think that their market supply is not sufficient. Respondents consider media and internet, as the most important information source that they wish to be informed on bio-food safety and control, ecological agriculture, eco-agroturism, as well as on the effect of agriculture on the environment. Through the statistics of robustness, it was found out that the effect of gender, education, economic activity and faculty of the surveyed respondents (students from Faculty of Biotechnology and Food Sciences (FBP) had a better information on bio – food) proved to be statistically significant.

Analysis of consumer behavior at chocolate purchase

At food purchase consumer is affected by several factors. In this work analysis of consumer behavior at chocolate purchase was performed involving 277 respondents. Statistical testing of results was performed by Chi - Square statistic, correlations have been tested with use of the Cramer's coefficient. It was found, that 86% of respondents consume chocolate. Factors affecting respondents at purchase were recommendations of friends, acquaintances (32%), brand of chocolate (24%), price (16%), personal experience (12%), health restrictions and allergies (11%). Less important factors when choosing chocolates are flavor (4%), nutritional quality (3%), country of origin (2%) and chocolate packaging (1%). In the consumption of chocolate moderate correlation among various categories of economic activity of respondents was confirmed. Chocolate was consumed mainly by respondents whose monthly income ranges from 801 to 1001 €. We found that consumers prefer milk chocolate followed by dark and white at the end. In terms of gender the most commonly was chocolate consumed by women, once to three times a week. The same frequency of chocolate consumption dominates at the categories of students and employee. Expenses frequently spent to buy chocolates were from 1-3 € per week by young people (18-23 years) and middle age generation of people (46-55 years)

Organic products, consumer behavior on market and european organic product market situation

The market of organic products around the world increased its volume in Central and Eastern Europe with organic food market has a number of shared features, which include the relatively low demand for organic food, low share of regular customers, the problems of producers marketing, the lack of enterprises which process organic products. Consumer behavior purchasing organic foods is influenced by several factors, among which is dominated consumer personality, income, finances and lifestyle, as well as psychological factors such as perception, motivation, learning, cognition and attitudes. Cultural and social factors in consumer behavior exhibit a lesser degree. Organic fruit and organic vegetables quality is generally higher for content of biologically active substances such as vitamins, polyphenols and flavonoids. The content of pesticide residues in organic food is significantly lower than conventional production. Regular monitoring of chemical and microbiological safety of organic products already in the primary production occurring in the raw state and after working in various sectors of food, an intensification of awareness raising and targeted increased support for organic agriculture. Multifunctional sector and increased support for family farms oriented for sectors with higher added value than the home sale, production processing on the farm and so on. By support of the sale of high quality domestic production by the state will be possible to persuade more people to personal health status and greater consumption of organic food  affects the health and prevent the occurrence of various diseases

Perception of bio-food labeling by consumers in Slovakia

    The paper presents an overview of the present perception of bio-food labeling by consumers in Slovakia. Analyses were realized by the questionnaire survey organized in the period December 2009 to January 2010. In the survey, 388 respondents were interviewed. From the methodological aspect, basic approaches of descriptive statistics have been used, as well as methods of association measurement. The test of robustness tested Chi-Square statistic. The robustness have been judged based on the p-values. Correlations have been tested through the Contingency coefficient and Cramer´s V coefficient. The survey showed that dependency knowledge of logos was confirmed in terms of knowledge of bio-food, education, type of employment, study at FBP faculty and in terms of choice of organic foods by manufacturers. Students of FBP  knows more bio-food logos than other respondents. The second highest dependency was confirmed within selection of bio-food produced individual manufacturers

Agricultural Cooperatives and Their Impact on Economic Performance of Farms in Slovakia

Effects of membership in cooperative organizations was investigated in many studies, and their results were sometimes controversial. Presented paper contributes to discussion related to cooperative membership by comparing members and non-members, with elimination of self-selection bias, to identify motivation to become member and main effects coming from membership in producer organization. Panel data used in the presented analysis are from Ministry of Agriculture of Slovak Republic at farm level for period of years 2009-2016, which was the most recent available data. Propensity score matching approach was applied to eliminate self-selection bias and to create sample of members and corresponding non-member farms in each year. Difference between these two groups were evaluated by methods of statistical inference. In general, it can be concluded, that in presented period were members of producer organizations more profitable than non-members. Also difference in total revenue was significant in period of year 2010-2013, which means probably successful using of advantage from better bargaining position of producer organization, compared to non-members. Significant difference in profit disappeared in last three years 2014-2016, this could suggest, that membership in producer organization was less attractive to many farms which led to decrease in number of members. Membership in producer organization probably improved economic performance of farms in Slovakia in period 2009-2013, but this advantage disappeared in last years. This could be probably linked to support for producer organizations from European Union in period 2007-2013

Eco-efficiency in agriculture of Europe an Union member states

The objective of the paper is to estimate efficiency and eco-efficiency of agriculture in 24 EU Member States from 2006 to 2015. In the study, a panel of yearly aggregated data [Eurostat 2018] of the total value of agricultural goods output (AGO), labour (AWU), utilised agricultural area (UAA), fertilisers N, P, K (NPK) and greenhouse gas (GHG) emissions of agriculture of selected EU Member States were used. The directional distance functions (DDF) approach both with and without undesirable output (GHG emission) were employed. Malmquist-Luenberger indices were applied to measure productivity changes and their decomposition to identify sources of these changes. GHG emission reduction per agricultural output in all EU MS was observed. Significant growth of GHG per UAA occurred especially in the OMS: The Netherlands, Austria, Germany, France, while an increase of GHG per UAA was less pronounced in Bulgaria, Latvia, Hungary (NMS). The highest efficiency and eco-efficiency in agricultural production over 2006-2015 was reached by the Netherlands and Denmark. The most inefficient and eco-inefficient agriculture was noted in the agriculture of Ireland and Finland (OMS). The highest inefficiency among NMS was detected in the agriculture of Lithuania, Poland and Latvia, while the most eco-inefficient were Latvia, Lithuania and Estonia. Improvement of productivity and eco-productivity due to technological improvement occurred in all 24 EU MS. Agricultural technical eco-efficiency fell in Bulgaria, Romania, Greece, Portugal and Hungary

Alternative Models for Calculation of Static Overturning Angle and Lateral Stability Analysis of Subcompact and Universal Tractors

Vehicle lateral stability is evaluated using the static overturning angle. The correct value of this parameter depends on the calculation method. The aim of this study was to compare the latest standard with previously published methodology, to propose two alternative methodologies (Models 1 and 2) and to analyze the influence of various levels of rear wheel ballast weights and overall tire widths on the stability of universal and subcompact tractors. The results showed a significant regression effect of the rear wheel ballast weight on static overturning angle. The influence of the rear wheel ballast weight was higher in the subcompact tractor than in the universal tractor due to a larger distance between the height of the center of gravity and the center of the rear axle. Comparing the latest standard with the previously published methodology, the highest difference values were 13.82% and 7.30%. Both models are based on the previously published methodology and differ from each other in rolling and slope lines. The methodology proposed in Model 2 differed from the standard similarly to the previously published methodology; therefore, it is irrelevant. Model 1 reached differences of only −1.81% and −1.63%, representing a minimal difference from the standard
