ANALYSIS AND PREDICTION OF PRODUCTION CHARACTERISTICS AND PRICES OF HONEY PRODUCTION IN THE VOJVODINA REGION

The aim of the research is to establish the state of honey production based on the current production and economic characteristics in order to predict their tendency for the period 2023-2026. The analyzed data refer to the number of beehives, total production, and yields of honey for the period 2006-2021, which were provided by the Statistical Office of the Republic of Serbia. In order to analyze the characteristics of honey production and prices the method of descriptive statistical analysis was applied: arithmetic mean (ẋ), extreme values ​​(min and max), coefficient of variation (CV), and the annual rate of change (r). The analyzed data indicate that total honey production and the number of beehives increased at an average annual rate of 6.09% and 6.27%, respectively, while the yield has declined slightly at an average annual rate of 0.17%. The trend of increasing the number of beehives and total production, and decreasing yields will continue in the prediction period. The purchasing price of honey has a tendency to increase (r=4.97). In 2026, the price is projected to be 5533 euro/ton, which means that the expected price of honey will be higher than the average by 3184 euro/ton

State and tendencies of production characteristics of wheat and maize in Serbia

The aim of the research is to determine the state and tendencies in the movement of production parameters of wheat and corn in Serbia for the period from 2005-2020. Analyzed parameters are harvested area, yield and total production. Descriptive statistics were used to determine the state and tendencies of the observed features. In order to predict the value of production parameters from 2021 to 2023, two methods were used: ARIMA model and extrapolation of the average rate of change of the analyzed parameters. Since the ARIMA model did not give satisfactory results due to a short time series (16 years), annual rates of change were used to extrapolate the production characteristics for the period 2021-2023. Using extrapolation of the average rate of change, the authors concluded that the yield of corn and wheat in the analyzed period showed a tendency to grow, with the areas of both crops showing a tendency to fall. Total wheat and corn production have a tendency to grow when compared with the averages of the analyzed period in previous years. The results of the forecast indicate that the volume of wheat production is expected to be 15.54% higher, and the volume of corn 28.41%, during the prediction period in relation to the multi-year averages of the analyzed period

Traditional food products on the local market - consumption conditional on the characteristics of management and restaurant facilities in tourism of Vojvodina (Serbia)

The research dealt with traditional food products (TFP) observed on the local hospitality-touristic market, from the point of view of 300 restaurant workers employed in managerial positions, as important subjects in preservation of tradition in hospitality and touristic industry of Vojvodina (Republic of Serbia). The research examined the management’s views on TFP, as well as whether there are differences based on the features of the respondents as well as the restaurant facility. In order to obtain data that would provide additional guidelines for acting on the hospitality and tourism market, the procurement and consumption of TFP was also examined. In order to determine set differences the non-parametric Kruskal-Wallis test was applied. In order to establish statistically significant differences between the observed groups, the Dunn’s post hoc test was applied. In the second part of the research, a binary logistic regression model was applied in order to determine which of the observed variables has a significant impact on the respondents’ decision to acquire TFP from their field. The research showed that the level of education and the field of management education significantly influence the attitudes about the offer of TFP in the hospitality and tourism market, as well as the type of restaurant offer and the development of the field of business

Analysing and prediction of cereals production characteristics in vojvodina

In this paper important kind of cereal crops in Vojvodina were analyzed (wheat, corn, barley, oats, rye and triticale). The production parameters include the cultivated area, annual production and yield of these cereals in the period 2005-2019. Method of descriptive statistic is used for analysis. Based on result of analysis, using extrapolation method, production parameters were predicted for the period 2020- 2024. Prediction is important for macro and micro planning of cereal production. Corn and wheat are two the most important kind of cereal crops in Vojvodina. They are also important for Serbian agriculture, too. Area under the cereal crops has tendency of decreasing, but because of positive tendency of yield, annual production show slow increasing tendency. Yields of all kind of cereal crops in Vojvodina are higher than in Serbia. Production and economics stability of cereal crops in Vojvodina were present in analyzed period, and they have a tendency to be stable in a future

Assessment of Beef Manure Economic Value by the Method of Equivalent Green and Mineral Fertilizer Substitution

The imperative of sustainable agricultural development, coupled with growing challenges related to climate change reaffirms the importance of manure and increases the demand for it. Due to the underdeveloped market for manure, there is a problem in assessing its economic value, requiring appropriate research on this topic. Thus, this research aimed to assess the manure’s economic value using the method of equivalent substitution. For this purpose, the chemical composition of manure was determined by standard agrochemical analyses concerning the content of the most important mineral elements—nitrogen (N), phosphorus (P2O5), and potassium (K2O). These elements ranged from 0.49–0.60%, 0.15–1.10%, and 0.70–1.07%, respectively, and the content of organic matter ranging from 20.88 to 27.00%. Subsequently, the cost of equivalent substitution was calculated taking into account market prices for commercial fertilizers and organic matter based on the cost of an adequate quantity of white mustard—Sinapis alba L. fresh mass. The average cost of equivalent substitution for manure was determined to be 28.60 USD/t. The results of the applied t-test indicate that there is no statistically significant difference between the market prices of beef manure and the calculated prices of its substitution (t = −1.4069; df = 12; p = 0.1848), which implies that white mustard green manure could replace the deficit in animal-derived manure. Since both animal and green manures unambiguously should be prioritized over chemical fertilizers, future studies will reveal which other crops are applicable for further increments of green manure to make up for insufficient availability of animal manure
