The purpose of this paper was to determine whether the Covid-19 Pandemic influenced the change in the extent of online shopping of organic food in Serbia and whether it has led to a change in organic food consumer behaviour. The survey was carried out in Serbia by using a questionnaire developed specifically for this purpose. The total sample size included 1022 respondents of which 90 respondents were online buying organic food during Covid-19 Pandemic. Descriptive statistics and Chi-square test were used to analyse data obtained from the survey. The results indicate that the Covid-19 Pandemic influenced the increase in the percentage of consumers who purchase organic food online. Also, the changes in the type and volume of organic food consumption were identified. Besides, the consumption of organic food varied in relation to the sociodemographic characteristics of consumers who purchased online.

The goal of the research was to investigate the effect of dietary natural or biotic additives such as garlic, black pepper, and chili pepper powder in poultry nutrition on sustainable and economic efficiency of this type of production. A total of eight dietary treatments with 1200 broiler chickens of hybrid line Hubbard were formed, with four replicates. During the experimental period, chickens were fed with three period mixtures diets of different average costs: Starter compound mixture two weeks (0.38 €/kg in all treatments), grower compound mixture next three weeks (0.36, 0.38, 0.40, 0.41, 0.46, 0.39, 0.42, and 0.39 €/kg, respectively), and finisher compound mixture for the final week (0.34, 0.36, 0.38, 0.39, 0.44, 0.37, 0.40, and 0.37 €/kg, respectively). The experiment lasted a total of 42 days. Upon finishing the experiment, results have shown statistically significant (p < 0.05) differences regarding the European broiler index (EBI) as one of the indicators of economic efficacy. The EBI was lowest in the control treatment (220.4) and significantly higher in experimental treatments (298.6), respectively. In cost, a calculation included the cost of feed and used natural or biotic supplements in chicken nutrition. The findings of the study of economic efficiency revealed that the cost per treatment rises depends on the natural additive used. Economic efficiency analysis showed that the most economical natural additive with the lowest cost is garlic (0.68 €/kg), while the most uneconomical is treatment with black pepper with the highest cost of body weight gain (0.82 €/kg). This higher cost of the gained meat is minimal as a consequence of a much healthier and more nutritious food meant for human use, which often promotes sustainable aspects, compared to conventional and industrialized poultry production.

Abstract. When speaking about the total number of highly educated individuals' migration, it is easy to spot

There is a significant amount of research in the world on the factors that influence consumers' decision to buy organic food using traditional sales channels. There is also a lot of research related to the factors that influence consumer decision to online shop groceries. However, to our knowledge, there is an extremely modest amount of research on how and why consumers decide to online shop organic food. The Covid-19 pandemic has led to an increase in consumer propensity to shop online, so this topic has gained in importance. Therefore, the aim of this paper was to determine the factors that most influenced consumers' decision to online shop organic food during the Covid-19 Pandemic. The survey was carried out in Serbia by using a questionnaire developed specifically for this purpose, based on questions from 9 relevant surveys in the world. Factor analysis and standard multiple regressions were used to analyze the data obtained from the survey. Four factors have been identified that influenced the online shopping organic food during the Covid-19 Pandemic. The first and most important factor is the Attributes of organic food and deterrents for purchasing. The second important factor is the advantages of online shopping, Covid-19 Pandemic consequences, and organic food labeling. While the third factor (Website characteristics and satisfaction with online shopping) and the fourth factor (Safety of online shopping) are of minor importance. At the end of the paper recommendations for improvement marketing strategy for online selling organic food are given.

One of the primary benefits of sustainable retail over the long run has to be the marketing gain from having something other competitors do not: lower operating costs, a more socially responsible public profile, ease of gaining planning approval for new projects, better access to certain investment pools, higher rents (in the case of developers), ease of recruiting and retaining key people. Each of these benefits needs marketing and public relations support; each benefits from a clear and consistent corporate message that promotes sustainable retail.To date, there are very few retailers or developers who have championed sustainability long enough, consistently enough and with enough actual demonstration of changes in standard operations to gain the benefits of green marketing, but the very paucity of examples serves to underscore the point: the green marketing space is wide open for large retailers and developers.What would be the marketing steps that a company could take to benefit from its “sustainability focus?” The key to any marketing program is to differentiate a company’s actions from those of competitors and to do it along lines that its various stakeholders care about. This practice of differentiation is often expressed as “finding a difference that makes a difference, to someone who makes difference to you.”For retail developers, the first differentiator should be to attract more and better tenants to all of their centers, tenants who value lower operating costs and the developer’s program of sustainable development and corporate social responsibility.
