Ecological agriculture is a developing sector in Romania, the farms’ profitability depending directly on their physical and economic size. Large ecological farms are fewer in this sector, but due to their size they succeed in dealing better with high investments costs and in managing more effectively the process of production, animal husbandry or crop cultivation. The methodology used in this paper is based on the data gathered from an agricultural business of 750 hectares in the southern part of Romania and includes calculations specific to economic-financial rate of return, starting from the company’s economic outturn account. The analysis performed and presented in this paper contributes to increasing the knowledge and importance of the information provided by this ecological farm’s economic-financial rate of return.

Migration is a basic major component of population dynamics which is characterized by deliberate rational decision of the migrant. This phenomenon has been viewed differently by different people, with some mentioning it as a cause of degradation of rural and urban ecological resources. Some associate the spread of HIV/AIDs and recently the Ebola Virus Disease (EVD). The most positive and powerful outcome of migration is remittance income. The significant contribution of international remittances to the stability and sustainable growth prospects of developing countries cannot be overemphasized. Remittances have not only grown strongly in a positive direction, but these inflows have also exhibited a much more stability than other private capital inflows and Overseas Development Assistance (ODA). Remittances are playing an increasingly large role in the economies of many countries, contributing to economic growth and to the livelihoods of people.

The paper goal was to set up a simplified BLUP model in order to estimate the bulls' breeding value for milk production characters and establish their hierarchy, Also, it aimed to compare the bulls' hierarchy set up by means of the simplified BLUP model with their hierarchy established by using the traditional contemporary comparison method. In this purpose, a number of 51 Romanian Friesian bulls were used for evaluating their breeding value for milk production characters: milk yield, fat percentage and fat yield during the 305 days of the 1st lactation of a number of 1,989 daughters in various dairy herds. The simplified BLUP model set up in this research work has demonstrated its high precision of breeding value, which varied between 55 and 92, and more than this it proved that in some cases, the position occupied by bulls could be similar with the one registered by using the contemporary comparison. The higher precision assured by the simplified BLUP model is the guarantee that the bulls' hierarchy in catalogues is a correct one. In this way, farmers could chose the best bulls for improving milk yield in their dairy herds.

The paper aimed to present the results of a meeting and discussion with many farmers about their business and the agricultural association they are dealing with. These discussions were focused mainly on the agricultural association of the Romanian farmers, about its objectives, activities, production and agricultural products and food products and economic efficiency. The research work was based on a Field Survey, using the questionnaires designed in advance including a list of questions destined to identify the situation of farmers between whose age was between 25 and 45 years. The two young farmers have been the interviewees included in the target group who answered the questions. The conclusions presented in this study emphasized the aspects regarding the collaboration within the association in order to achieve the production and products, how problems are solved and performance is achieved.

This paper is a quantitative research which highlights aspects about production and marketing of cherries and sour cherries in Romania. In order to achieve the objective, the relevant indicators were analyzed during the period 2012-2016. The indicators analyzed in the paper refer to the number of cherries and sour cherries at national level as well as at macro-regional level; cherry and sour cherry production in Romania and on macro-regions; average production of cherry and sour cherry tree at national and macro-regional level; prices for cherries and sourcherries in Romania; average consumption per year of cherries and sour cherry at national level, also imports and exports. In Romania the cherry is a very productive culture, which has contributed to the achievement of notable performances from production point of view. The placing on the third place in the world ranking in terms of yield per hectare is conclusive. In 2016, the Romanian cherry production accounted 8.2% of the production achieved at the level of the European Union. The National Institute of Statistics is the main source of data used in this study.

The paper aimed to establish a corresponding regression model reflecting the relationship between profit, as the main barometer of economic efficiency and milk yield in dairy farming using a sample of 8 farms operating in the Southern Romania. Two regression models were compared: the linear regression and the quadratic fit. Average milk yield registered 6,088.57 kg/cow and had just 9.24 % variation among farms. Profit per cow recorded Lei 2,096.57 in average with a very high variation from a farm to another ( 46.20%). The correlation coefficient between milk yield and profit per cow, rxy= 0.921, reflected a strong positive link between the two economic indicators. The regression model had the form Y=1.584x - 7,508.66 with the standard error Sest= 407.370428 and the parabolic fit was Y=0.006x2 -5.7649 + 14,250 having a higher standard error Sest= 18,786.96. From this comparison, the linear regression model proved to be the most suitable one to reflect the relationship between profit per cow and milk yield with the highest accuracy. According to this model, it was estimated that for an annual 500 kg gain in milk yield, profit per cow could be higher by Lei 792 per year with a deep impact on farm profitability.

The paper purpose was to apply a simplified mixed model BLUP for estimating bulls' breeding value for meat production in terms of weight daily gain and establish their hierarchy, Also, it aimed to compare the bulls' ranging obtained by a simplified BLUP mixed model with their hierarchy set up by contemporary comparison. A sample of 1,705 half sibs steers, offspring of 106 Friesian bulls were used as biological material. Bulls' breeding value varied between + 244.5 g for the best bull and -204.7 g for the bull with the weakest records. A number of 57 bulls ( 53.77%) registered positive breeding values. The accuracy of the breeding value estimation varied between 80, the highest precision, in case of the bull number 21 and 53, the lowest precision, in case of the bull number 38. A number of 7 bulls of the total of 57 with a positive breeding value were situated aproximately on the same positions at a difference of 0 to 1 points on the both lists established by BLUP and contemporary comparison. As a conclusion, BLUP could be largely and easily applied in bull evaluation for meat production traits in term of weight daily gain, considered the key parameter during the fattening period and its precision is very high, a guarantee that the bulls' hierarchy is a correct one. If a farmer would chose a high breeding value bull from a catalogue, he could be sure of the improvement of beef production by genetic gain.

The paper aimed to analyze the evolution of the population occupied in tourism compared to the population occupied in the national economy in the period 2007-2015 using the empirical data provided by National Institute of Statistics. Index method, comparison method, descriptive statistics, Pearson correlation coefficient, linear regression function, and Herfindhal-Hirschman and Gini-Struck indices were used as methodological framework. The population occupied in tourism activities increased by 12.02 % from 155.5 thousand persons in 2007 to 174.2 thousand persons in 2015. Tourism contributes by 2.07 % to the population occupied in the economy. The Bucharest-Ilfov, Centre and SE micro-regions have the highest number of population working in tourism: 21.19%, 16.07%, and respectively 12.45%. The South West Oltenia and West micro-regions have the lowest shares of population employed in tourism. The persons working in tourism are relatively uniform distributed in the territory as confirmed by Herfindhal-Hirschman and Gini-Struck indices. The tourism structure by professional status is: 90.8 % employees, 3.8 % employers and 5.4 % self employed people, higher figures than in the national economy. Tourism absorbed more younger persons than in the national economy. About 13.5 % of the employed persons in tourism belong to the 15-24 years category and 34.5 % belong to the 25-34 years category. The correlation coefficient r=0.588 between the number of people employed in tourism and the number of units for tourists' accommodation reflects that a higher number of tourists will require a larger accommodation capacity and more employment in tourism activities. The correlation coefficient r=0.355 between the number of places (beds) and the number of persons occupied in tourism is a weak. As a final conclusion, tourism is a dynamic branch of Romania's economy with a high potential to create jobs, employ young people and also women.

Cultivated by passion or as part of a business, flowers are present at any event in people's lives, either joyful or sad. As the European flower market is a large and varied one, the aims of this article are: to present the evolution of European flower market between 2008-2016 using as main indicators: the areas cultivated and the total production obtained in the European Union; the import and export values; to sketch the cultural role of the most traded species. The economic data taken from the European Commission - Agriculture and rural Development, Eurostat and International Association of Horticultural Producers (AIPH)sites,were processed and interpreted statistically; while for the symbolic values of Roses, Carnations, Lilies, Chrysanthemums, Orchids and Gladioli we used documentation on various, eclectic, formal sources related mainly to religion, art, florigraphy. Results highlight that the European Union represents 10% of the world's floral area and 31% of the value of flower and ornamental plants production in 2016; the Netherlands, France and Italy are the main producing and cultivating countries; the European Union is an exporter of cut flowers and foliage, potted plants, conifers, perennials, bulbs and corms, and, first of all, an importer of cut flowers and foliage. The trade balance is in favor of exports.
