After approval of the Declaration of Independence (August 27th 1991), Moldova lives hoping to consolidate their place among the democratic nations of the world and to build its new socioeconomic system. Agriculture has been and remains the strongest factor of balance in harmonizing economic development of any country, including our country. Moreover, for us agriculture has a significant contribution to the gross domestic product, which even if reduced from 36.14% to 15.23% in 1990 to 2014, remains the backbone of the national economy. The level of agricultural development of our country undoubtedly is dependent on natural resources and materials that are emphasized by the available human potential. Sure, all those involved in the agri-food sector must increase its effort to gain new generation of products, to develop and apply appropriate technologies for their production would exclude or, at least, limit risk and uncertainty. It is natural to manifest constantly awake curiosity and also hard to available human potential for national agriculture, creativity farmers achieve the desired result. The article reflects on human potential evolution of the number of people employed in national agriculture, knowledge and skills, professionalism and creativity of farmers. The authors come up with some proposals that would help ensure agriculture with the necessary human resources, in order to enhance professionalism and creativity of those working in this sector of national economy.

Increase agricultural output is conditioned by a number of factors, among which the protection of plants against pests plays a very important role. Along with chemical methods, methods of biological and integrated control against harmful organisms in crops have recently taken on a large scale, and one of these methods is the use of entomophages (predators and parasites). In order to identify and monitor species of entomophagous arthropods from the winter wheat culture, in the years 2016, 2017, an experiment was carried out in two locations in the center of Transylvania, namely in Turda in open field agroecosystem and in Bolduţ, in agroecosystem with protective agroforestry curtains. The field results were calculated and interpreted using ecological indices (abundance, dominance, constancy, and W ecology significance index). In addition to the monitoring of the entomophages, production and some of its components were determined. Entomophagous arthropods identified in the two agroecosystems differ only in ecological indicators, belonging to the same groups of entomophagous. The positive role of the agroforestry curtains in Bolduţ reflected both on the abundance of entomophages and wheat production, obtaind an 8% production increase compared to the production made in the unprotected system in Turda.

The research recorded the respondents’ opinions and attitudes within the local public administration in Călăraşi county, on the identification of the specific leadership skills and behaviors. The research method used was the survey, having as a research tool a semi-standardized questionnaire, with a total of 12 questions applied to 209 persons within the 37 town halls in Călăraşi county. It is found out that the persons with secondary education perceive the leaders within the organization as having an authoritarian leadership style, while the persons with higher education perceive the leaders as having a collaborative/participatory leadership style. Also, depending on the sector in which it operates, the employees of the public administration institutions in the rural areas tend to practice an authoritarian leadership style, while the employees of the town halls in the urban area tend to a collaborative leadership style. The two aspects correlate, as in the town halls in the rural area, most employees and local councelors have only secondary education, while in the urban area the situation is changing in favor of the employees with higher education. After processing the data it was found out that in terms of leadership style existent in the public administration in Călăraşi county the collaborative style prevails by a majority of 56.3%, facilitative style 9.3% and 34.4% the authoritarian style.

The present questionnaire study was conducted to establish potato purchasing preferences of 385 consumers selected randomly from Igdir, Turkey. All the items ranging from 1 to 11 on the basis of an ordinal 11 point scale data on fresh potato and its products were collected from the consumers. Robust Unweighted Least Squares (RULS) extraction method was used based on promin rotation method for obtaining better solutions in the ordinal data set. Polychoric correlation matrix was used instead of Pearson correlation matrix in the violation of the basic assumption on normal distribution of the ordinal items due to the fact that it is evidence that null hypothesis of multivariate asymmetric kurtosis was rejected (P=0.000). Four new factors were extracted from all the items on both fresh potato and its products through 'Factor' software program, which gives more comprehensive and understandable outputs. The rotated factor loadings for potato products were clustered into four factors: content (Factor 1), value of nutrient and calorie (Factor 2), additives and price (Factor 3) and situation of package and health (Factor 4), respectively. The rotated factor loadings for fresh potato preferences of the consumers were also assigned to four factors: source (Factor 1), price and color (Factor 2), tubers structure (Factor 3) and tubers properties (Factor 4), respectively. The current results revealed that an application of EFA factor analysis on the basis of ULS extraction method, promin rotation method and polychoric correlations as a dispersion matrix was more effective when compared with the traditional EFA applications for the ordinal data. Besides, potato producers, sellers and entrepreneurs who desire to develop new marketing strategies might be recommended to take into account four factors that can affect purchasing preferences of the consumers on fresh potato and its products.

Our research aimed at identifying the main volatile compounds, including the volatile thiols, from 2 Sauvignon Blanc wines, obtained in Dragasani vineyard, 2014 harvest. Wines were obtained using 2 yeast strains of Saccharomyces cerevisiae, one commercial used in wine industry and the second being obtained by screening, in Dragasani vineyard. By GC/MS technique were identified and determined quantitatively three compounds of the mercaptans group, having an important contribution in the Sauvignon aroma, namely: 4-mercapto-4-metylpentan-2-one, 3-mercaptohexan-1-ol and 3-mercaptohexyl acetate. The results showed the positive influence of the yeast strain Saccharomyces cerevisiae selected from Dragasani area, over concentration in volatile thiols and consequently, on the flavor of Sauvignon wine, obtained by fermentation with this strain.

The aim of this study is to assess the impact of the possible reduction in Tariff Rate of sugar in Turkey under The World Trade Organization’s (WTO). Sugar is an important product for human life and obtained from sugar beet, sugarcane, starch-based sweeteners and chemical sweeteners. In almost all countries a protected product and 70% of world production is consumed in the domestic markets of the countries and remaining 30% share in the sugar trade between countries as an important product.Sugar is obtained from sugar beet in Turkey and it’s Tariff Rate is 135%. Under the title of market access in WTO, tariff reduction for products which are protected by more than 130% is 46% in developing countries. In this study; there are four model considered such as production, consumption, import and export and analyzed with 2 different scenarios which are zero Tariff Rate and prices after 46% discount on Tariff Rates of sugar. Partial equilibrium model was used. According to research findings; in each of two scenarios consumer welfare is observed to be increasing but these increases remain in low level. Producer and social welfare have emerged negatively in all three scenarios and the negative effect has been observed.

This study investigates the impact of municipal waste on the physicochemical parameters of Epe Lagoon. Three stations were chosen where a lot of human activities take place. The samples were collected from surface water at 10cm depth for 12 consecutive months in duplicates between August 2014 – August 2015. pH, dissolve oxygen, conductivity, total dissolve solids, salinity, temperature, turbidity, dissolved oxygen and the biological oxygen demand were measured. The pH measurement was highest in March with mean value of 7.9±0.17, a rainning month and lowest in October, a dry month with mean value of 6.1±1.21 The mean dissolved oxygen value was 7.17±0.67 mg/l. The annual mean salinity value was 0.08 ppt. The water turbidity was highest in March with mean value of 68.3±3.15 mg/l and lowest in the month of June with mean value of 47 ±1.21 mg/l. The mean nitrate value was 1.31±0.07 ppm. The mean value of alkalinity was 58.34±0.67 mg/l and that of phosphate was 7.52±0.67 mg/l. Conductivity mean values ranged from 76.94 ±5.35 uhoms/cm-1 in the month of November to the highest in the month of June with a value of 94.87 ±1.39 uhoms/cm-1. In this study BOD mean value was 1.84±0.67 mg/l . Regulatory bodies should spring into action to control the dumping of munincipal waste along the course of the lagoon so as to prevent the extinction of aquatic life in the water boody.
