The paper presents the main tendencies in the production and marketing of apples in Romania during 2012-2016. In order to carry out the present study, a number of indicators were analyzed: the number of apple trees from the national category and from the development regions of Romania; total apple production; average production per apple tree; average price for table apples; average annual apple consumption per capita; imports and exports of apples. Currently, Romania ranks second in terms of apple cultivated area and seventh in terms of apple production at EU level. The data used in the present paper was taken from the National Institute of Statistics and also from specialized international sites. The main tendencies in the production and marketing of apples were highlighted, especially from a quantitative point of view. In this regard, the changes that have occurred from one year to the next have been followed. Since there is a high potential for developing the apple production and marketing sector in Romania, a series of measures are required at both macroeconomic and microeconomic level.

The paper aimed to analyze the main trends in tourism demand in the top European countries in terms of tourist arrivals, overnight stays, tourism intensity, receipts, receipts/arrival, receipts/inhabitant. The correlation coefficient and regression function were used to analyze the relationship between tourist arrivals and tourism receipts. The top visited countries in Europe registered 377.8 million international tourist arrivals in 2015, by 17.07 % more than 322.7 million in the year 2007. Their market share in the EU international tourist arrivals was 78.8 % and at the world level 31.55 %. The decreasing order of these countries based on their market share in the EU tourist arrivals is: France, Spain, Italy, Germany, United Kingdom, Austria, Greece, Poland, Netherlands, Croatia and Portugal. These countries contributed by USD 302.2 Billion to the EU receipts coming from tourism, representing 80.2 % of the EU receipts. In 2015, all these 11 countries registered 2,035 million overnight stays, representing 86.5 % of the total overnight stays in the EU. Based on this indicator, the decreasing order of these countries is: Spain, France, Italy, Germany, United Kingdom, Austria, Netherlands, Greece, Croatia, Poland and Portugal. The number of overnight stays/inhabitant, reflecting tourism intensity, varied between 16.9 in Croatia and 1.9 in Poland. While the receipts/tourist arrival varied between USD 1,323 in United Kingdom, and USD 532 in France, the receipts per overnight stay varied between Euro 88 in Germany and Euro 194 in Portugal, and the receipts/inhabitant varied between Euro 248 in Poland and Euro 1,909 in Austria. The correlation coefficient, the coefficient of determination and the regression equations attested that between the number of international tourist arrivals and tourism receipts is a positive strong correlation in case of United Kingdom and Croatia. In case of Greece and Germany it was found a moderate positive correlation, while in case of Austria, France, Italy, Netherlands, Poland, Portugal and Spain it was noticed a weak correlation. Therefore, the number of tourist arrivals reflects an increased tourism demand, but it can't entirely explain the growth of tourism receipts, which are determined by many other factors.

The paper analyzed the trends in the tourism of the Maramures County, an important destination both for Romanian and foreign tourist due to its beautiful landscapes, cultural heritage and well preserved traditions. The empirical data were provided by the National Institute of Statistics for the period 2007-2016. The main statistical indicators used in this study were: number of units with reception function for tourists' accommodation, number of places, tourist arrivals, overnight stays and length of stay. They were statistically analyzed by: average, standard deviation, coefficient of variation, and trend line, and also by means of Spearman and Pearson correlation and regression models between number of places and tourist arrivals, and between number of places and overnight stays. Finally, the forecast for the number of tourist arrivals and overnight stays for the period 2017-2021 was set up using the adjusted series of data and the average growth rate. In the Maramures County, the tourism offer in terms of units with accommodation function for tourist reception increased by 47.05 % and the number of places by 77.46 %, accounting for 225 tourism units and 6,451 beds in the year 2016. The tourism demand, in terms of the tourist arrivals increased by 75 %, while the overnight stays raised by 48.24 %, accounting for 189,000 persons and, respectively, 339,000 overnights stays in the year 2016. The average length of stays declined by 15.7 % from 2.11 days in 2007 to 1.78 days in 2016. The Spearman correlation coefficient reflected that between the number of places and the overnight stays it is a weak positive relationship (rS= 0.079), but between the number of places and tourist arrivals it is a high and positive link (rS= 0.776). The Pearson correlation proved high positive values ( r= 0.771 and r= 0.893) for this pair of indicators. In the year 2021, it is expected that the number of tourist arrivals to reach 225,000 and the number of overnight stays to account for 386,860 in the Maramures county, reflecting the tourists' interest to visit this part of Romania.

Considering that the form and size of the goat's udder can influence its productive capacity, a series of measurements of certain dimensions of the udder at Romanian breeds Alba de Banat and Carpatina were performed, as follows: large perimeter of the udder, small perimeter of the udder, prior depth of the udder, back deepness of udder, length of udder, length and thickness of nipples. The primary data obtained was statistically processed using statistical functions available in Microsoft Excel and the main statistical parameters were determined: arithmetic mean, standard error of mean and variability coefficient. The udder measurements indicated that, in both breeds, the udder suffers transformations along lactations; thus, with regard to the large perimeter, as well as the small perimeter of the udder, the largest dimension is reached at the 3rd lactation, after which it begins to decrease. These dimensional evolutions indicate that the udder increases its capacity over the productive life of the animal in order to store the quantity of the milk. The same transformation curve has the nipples in the sense that both their length and thickness are amplified until the 3rd lactation and then begin to diminish. The length of the udder is higher at Carpatina by 20.3% than Alba de Banat, suggesting a longer form, but nipples at Alba de Banat are longer (by 9%) and thicker (by 22.7%) compared to Carpatina, so it is better suited to the mechanical milking.

The purpose of this work is to demonstrate the algorithm of actions for modern erosion-combating optimization of the land use structure by the example of a specific 30.01 ha study area with the help of updating the eroded soil type differences. Description and refinement of soil type difference was carried out by the way of making soil profiles, half-soil profiles and further surface interpretation on a base of laboratory soil samples results. The creation of a generalized digital elevation model (DEM) also has been taken into account to highlight the determination of slope gradient and the shape of the slope using the archive cartographic material of the scale of 1:10 000. Based on the obtained map of the slopes gradient and the generalized digital model of relief, contours of additional soil type differences were revealed, and appropriate recommendations for their use to precise farming, depending on their belonging to a certain eco-technological groups were presented. Such kind of information in the form of data files provides necessary support for programming the input of fertilizers or soil tillage operations on slopes in system of precise farming.

Considering the fact that milk is one of the strategic products for the economy of each country, there is a tendency to provide the population with sufficient quantities through the development of primary milk production. According to the conducted analysis, out of 1.5 billion liters of milk per year, approximately half, about 50%, is purchased by the dairy processing industry. Milk production and processing in Serbia is mainly focused on products that do not require a lot of time nor complex or lengthy technological processes of production. Such products have a short shelf life, but are most often consumed on the market. Fermented dairy products are the most important group of products in the market structure of domestic supply and demand. These products are the most popular commercial industrial products because they contain probiotic microorganisms that have a beneficial effect on the human digestive system. Since whey is a by-product of cheese and casein production, it is one of the underutilized by-products of the dairy industry in Serbia. Therefore, the first part of this paper analyses the production of cow’s milk and dairy products intended for the market in the period 2013-2015 with special emphasis on fermented milk products. The second part focuses on the utilization of whey, as one of the more effective solutions in the production of functional fermented whey-based beverages in the food industry, which mainly uses whey concentrate or whey powder.
