To highlight the influence of the climatic conditions of the harvest year on the main biochemical parameters, and therefore on the quality of the red wines obtained from the Merlot variety, 4 wines obtained in the Dealu Mare region were analyzed, in 2013, 2014, 2015 and 2016. The climate of the studied years presented differences in temperature and precipitation, leading to different accumulations of sugars and phenolic compounds; climatic conditions also had an influence on the other quality parameters of the wines. The biochemistry analysis of the wines aimed: alcoholic strength (vol% alcohol), total acidity (g/L tartaric acid), volatile acidity (g/L acetic acid), total and reduced dry extract (g/L), glycerol content (g/L), the content in total and free SO2 (mg/L). The influence of climatic conditions on the chromatic characteristics of Merlot wines was highlighted by spectrophotometric analysis of the total content of polyphenols (A280), the total content of tannins (g/L), including tannin structure (gelatin index, HCl index and ethanol index, %), content in anthocyanins (mg/L) and coloring intensity.

There are many situations where farmers exploit their fruit production just as it was harvested, without sorting the fruit by their quality or diameter. The present study that was carried out followed an economic approach of the pear fruit exploitation in terms of some quality aspects, namely it has highlighted the advantage of sorting the fruit into quality classes, as opposed to selling the fruit engross after being harvested from the orchard. The pear fruit belonging to the Conference, Beurre Bosc, Orizont and Cristal cultivars originated from a ten year old orchard located in the Bucharest area. The Orizont and Cristal cultivars in comparison with the Conference and Beurre Bosc cultivars display a genetic resistance to pear scab and fire blight diseases, which determined lower production costs, mainly due to less pre harvest intervention applied in the orchard. Both because of the above mentioned fact and the commercialization of the fruit after sorting, the obtained profit was between 1,150 RON/ha for the Conference cultivar and 13,900 RON/ha for the Cristal cultivar. This determined a higher value of profit, respectively between 5.5% and 25.1% in the case of the fruit sorted by quality criteria than for those exploited directly from the orchard, as soon as they have been harvested without any other postharvest intervention.

Culinary tourism, like any type of tourism is an economic activity, but it is part of the culture of the defined region. Therefore, practicing culinary tourism should be perceived primarily as a cultural enrichment of the individual person. The aim of the research is to establish the degree of interest in the practice of culinary tourism in Bulgaria; Preferences in a particular culinary area; Expectations from practicing culinary tourism. In order to achieve this objective, it is necessary to carry out the following tasks: To prepare an inquiry card; To conduct the survey among consumers; To carry out statistical treatment and analyse the results of the survey; To summarize conclusions. To achieve the purpose of the survey was conducted questionnaires – in person and through online form (inquiry card), in the period 05.11.2018 – 22.12.2018 year, among 104 people aged 18 to 51 years. The questionnaire contains 20 questions of different types – open, closed, multivariate. From the analysis of the results of the study, the following are summarized: respondents practice different types of tourism, and culinary is also present in their preferences. Through an appropriate advertising and marketing strategy, this interest can be strengthened and more actors attract. Respondents would visit each of the tourist areas in Bulgaria for culinary tourism, but as the most preferred they have defined the Rhodopi region. Respondents would be motivated to travel if it offered them a new, different experience; has a good quality/price ratio; It is related to the consumption of traditional as well as unique food and drinks. They are interested in local traditions, lifestyle and culture and would visit festivals, holidays, and domestic/traditional restaurants. The vast majority of respondents believe that the best advertising of culinary tourism can be accomplished through specialized sites, radio and television. They like long weekends outside their own location; The most preferred period for participation in culinary tourism is from 1 to 3 days. For a period of such a duration would allocate between 150 and 300 BGN, this amount does not include the cost of transport and accommodation. Respondents are young people, mostly women, most – family, highly educated and most of them live in a big city; Decide to participate in culinary tourism independently.

The article identifies that the logistics system of the vertically integrated Public Joint Stock Company “State Food and Grain Corporation of Ukraine” is the most exemplary in the grain subcomplex of AIC. The work outlines the research phases of the casual dependencies of the technical and economic parameters of the corporate’s logistics system efficiency and proposes a methodological toolkit for creating a common base for comparing the diverse activity of the corporation’s affiliations through the use of logistical grain equivalent. It is substantiated to choose the operating profitability as an integral indicator of the logistics system efficiency for the enterprises of the grain subcomplex of AIC. The suggested integral indicator allows eliminating the investment and financial activity of affiliations from the evaluation orbit, in order to focus on the implementation of logistical functions related to the transition and modification of the grain flow. According to statistical study results of certain parameters dependencies the suggested regression models can be used to predict unknown values of the indicators of logistics systems efficiency as far as the enterprises of the grain subcomplex of AIC are concerned.

The purpose of this work relates to the study of sunflower on an area of 8 ha, carried out in the territory of Ip in Sălaj County, Romania, on the land of a family farm. The choice of aggregates is also based on direct operating expenditures. When carrying out works with different agricultural aggregates, one should always choose the optimal variant that is apreciated by the minimum amount of the number of aggregates taking part in the performance of the work or the minimum amount of time, i.e., after the consumption of fuel. Two types of tractors were used for the execution of mechanized works in sunflower: Tractor U 650 M and tractor FENDT FARMER 311 LSA. In order to obtain large and high-quality production in sunflower, fertilization is of particular importance. The soil fertiliser reserve must provide plants with nitrogen, phosphorus and potassium supply from the first days of vegetation. The doses of fertilisers to be administered vary depending on soil reserve, soil type and on other factors related to climate and soil. The factors that influenced sunflower production in 2019 were: climatic conditions, crop rotation, soil fertility, mechanical work quality, sowing time, and cultivated hybrid.

The purpose of this study was to establish the existence of a correlation between mitotic activity in Helianthus annuus (sunflower) and seed production, taking into research five genotypes (G1-G5). The mitotic index had variable values (19.5%-39.4%). It was found a direct correlation between high mitotic activity (39.4%) and high production (2,105 kg/ha); the G3 genotype was the one that stood out from this point of view. Also, the G4 genotype, which recorded the lowest value of the mitotic index (19.5%), was noted with the lowest value of yield (1,758 kg/ha). The results suggest that genotype is one of the most dynamic indicators for sunflower cytogenetic research. This comes in support of genetic research for sustainable management of the agricultural system in general and sunflower crops in special. An intense mitotic activity is directly correlated with plant growth, development and fructification at optimal parameters. However, in addition to intense mitotic activity, environmental factors also play a decisive role.

This study has determined connection of governance mechanisms with cost of capital based on Agency and Stewardship theories for companies in agriculture sector in 20 Asian countries from 2009-2018 for 363 agricultural firms as agriculture significantly contributes in growth of Asian economies. The WACC variable is selected as a dependent variable, whereas quality of corporate governance practices (QCG) variable has been used as independent variable. The endogeneity of QCG variable was examined through 2SLS model and results depict that variable of QCG significantly and negatively affect the variable of WACC. Moreover, the variables of leverage, ROA, sales growth and stock’s volatility have significant positive connection with WACC, whereas, the firm size has significant negative relationship with the WACC. This research contributes to empirical literature by offering the first empirical support for analysis on association of governance systems and WACC for agricultural firms in Asian countries. These results are consistent with suggestions of Agency and stewardship theories and therefore, policy makers need to improve their corporate governance structures for attracting more investors and creditors around the world in agriculture sector.

Wine plants are cultivated on different types of soils with different degrees of fertility, from sandy ones up to clay ones. Consequently, the technology for maintaining viticulture plantations must improve their fertility state and the soil’s productivity. The large number of works and the repeated crossings with tractors and viticulture equipment in vineyards negatively influences the soil’s characteristics: structure degradation, surface and depth compaction, the decrease of humus content, reduction of biological activity, that can finally led to a decrease of the soil’s natural fertility. In this paper are presented different solutions for: preventing soil erosion; capitalization of viticulture fields in the conditions of applying a sustainable viticulture, remaking the water-air percentage and improving the soil’s biological activity.
