Research about the local sheep body weight selection response on various selection intensities has been held in Purwakarta, West Java, Indonesia, on November 2017. The aim of the research is to know the heritability and body weight selection response of local sheep as the genetic parameters. The purpose sampling data from 144 sheep (75 male and 69 female derived from six sires), are birth weight (January 2016 until December 2016) and corrected weaning weight on 100 days of age. The variety components and the heritability value were used variance analysis pattern of half-sib correlation. Fixed effect were used sex (male and female) and type of birth (single and twins) the average of birth weight was 2.73 Kg; weaning weight were 6.43 Kg and corrected weaning weight on 100 days of age were 9.32 Kg. Results of analysis data were shown the heritability value of birth weight was 0.32 is high category and the heritability value of corrected weaning weight on 100 days of age was 0.36 also is high category. The highest value of selection response body weight by heritability corrected weaning weight on 100 days (of one sire and eight ewes) with selection intensity 2.03 was 4.22 Kg.

The paper analyzed the contribution of the domestic trade to the economic development of Romania in the period 2008-2017 in terms of contribution to GDP, investments, jobs, labor productivity, number of companies in operation and turnover. The data taken from the National Institute of Statistics were processed using fixed basis indices, growth rates, structural changes, comparisons to emphasize the main aspects which characterize the evolution of home trade and of its subsectors. The results proved the important role that home trade has in the economy. In 2016, it contributed by Lei 160 Billion 918.7%) to GDP, by Lei 20.06 Billion (20 %) to the investments in the economy, by 1,884 thousand persons (22.5 %) to the occupied population, but in a lower measure to the increase of labour productivity. Home trade is attractive for small business investors as proved by the increased number of new companies in 2016. At present, 45.4 % of the enterprises operating in the economy are profiled on trade transactions. Also, home trade has contributed by Lei 565.1 Billion to the turnover in the economy. The increased sales are justified by the consumption high growth rate for goods and services. The wholesale and retail trade contributes by about 81 % to the national turnover. Therefore, trade is a very important sector of activity which supports Romania's economic development.

This article is concerned with studying the main trends connected with the changes of the borders of the Tara Irtysh area in the Soviet era. A wide range of sources, including some unconventional sources untypical of historical surveys (oral historical materials), was used as the basis of the research. The cumulative analysis of the above-mentioned sources enabled us to study the problem comprehensively, i.e. from the position of an inhabitant of the Irtysh area – the direct creator of history. The features of the used sources, the research object and its objective determined the basic tools that combined principles and methods generally accepted in historical science with peculiarities of new local history and rural history that were actively developing. In the course of the study, we have paid much attention to the factors determining the transformation of the rural settlement network under consideration throughout the designated period. We believe that the main factor was the state policy in the agrarian sphere. Among the reasons for the reduction in the number of villages were the policy of consolidation of the farms and the outflow of their population to cities, regional centers, and larger villages where the state planned to build central estates with a well-developed infrastructure.

The paper analyzed wheat and maize production, export and import in Romania in the period 2007-2016 in order to point out the main trends and factors which sustain the position of the country in the international trade. Index method, comparison method, export/production ratio, export/import ratio, gross exchange index have been determined to characterize efficiency of external trade. Maize and wheat production increased 2.8 times during the last decade, representing 50 % and respectively 38.5 % in cereal production. Romania comes on the 2nd position for maize and on the 5th position for wheat in the EU production. The production growth is due mainly to the large cultivated surface, 4.7 million ha, for these two cereals which represent 85 % of the cultivated area in Romania. But, with 4.1 tonnes maize and 3.9 tonnes wheat per ha, yield is by 42.39 % and respectively 26.22 % lower than the EU average. Romania exported 11 times more maize and 34 times more wheat during the last decade. Also, it imported less maize but more wheat mainly for re-export. Export/Production ratio increased from reached 0.32 for maize and 0.82 for wheat, and Export/Import ratio reached 7.78 for maize and 5.83 for wheat. Export and import value also had a high growth rate, while import had a decline, resulting a positive balance, and this under the decline of export price and increase of import price. As a conclusion, the production growth contributed to the development of export with a benefic effect on the trade balance and Romania's prestige and position as a cereal producer and exporter. To increase yield level, investments are required in new technologies ( machinery, irrigations, high production value hybrids and varieties, fertilization and plant protection). Also, farm size should be increased by joining in associative forms for a more efficient use of capital and human resources and increase economic efficiency.

Regardless of its geographical position in Romania, corn is a plant of great importance for both human alimentation and animal nutrition, mostly in rural areas. Experiments conducted on the eutricambosoils from Brebu village have found that locals are using local varieties, with a 2-3 times lower productivity than that of specific hybrids in the area, but also that they are using monoculture, sometimes unlimited in time. Our experiences aim was that of changing some technological system links even on small surfaces of 1-5 ha. For this purpose, the varieties were replaced with hybrids, which leaded to yield increases of 1.5 times. It was also introduced the fertilization with compost obtained in the household, while potato, peas, alfalfa (jumping field) and corn were used as previous crops. The experience conducted for 10 years only confirms the negative effect of the local variety and of the monoculture (annually yields of about 5-10 q/ha). The ameliorative previous plants, such as peas and alfalfa, increased by only 4.6 q/ha the corn yield of the variety, which had no significant reactions not even to the compost fertilization. Introducing a hybrid from FAO 300 group, crop rotation and compost manure led to an increased corn production of up to 55 q/ha, opening a new economic vision for those who have chosen to try this system.

The need for funding of the agricultural sector in recent years is growing in the situation when agricultural enterprises are consolidating in order to sell the produced products on domestic and international markets. On the one hand, there is a trend of land consolidation, and on the other hand, farmers want to buy all the tools and equipment necessary for carrying out their business. Heavy investments are made in inputs (quality seeds, fertilizers, animal varieties and breeds with high efficiency, etc.) and how these are mostly imported at world prices, the need for further funding increases. All these lead to the continuous growth of the need for financial resources. Another problem lies in the inefficient management of funding sources. With increasing investment in agriculture, Republic of Moldova faces constraints of implementation capacity. The research purpose is to analyze the efficiency of investment in agriculture and to determine the optimal level of investment for 1 ha of agricultural land.

Agriculture is one of the main axis of our national economy, but it can get further improvement not only in environmental level but also for the human resources who consist it. The main purpose of this study was to examine the behavior of organic farms managers. Specifically producers’ demographics were investigated through a questionnaire. The results of this study indicates, that the majority (87.76 %) of the organic farmer managers are male. As for the educational level, the majority of farmers were high school graduates and their age comes close to an average of approximately 43 years old. Furthermore the main source of income (83.67 %) for organic farm managers proves to be agriculture. In addition we examine the farmers’ opinion on the necessity of subsidies and potential obstacles acquiring organic certification. The recorded percent of the organic farmers responded positively to the necessity of the subsidies is 42.9 %. The study also presents the main given products in organic open farmers’ markets and the cultivation characteristics such as land, fertilization and distribution of the cultivated products. The majority of the products that sold in organic open markets are vegetables followed by olive oil and legumes. An important feature of this study, also linked to the attempt to convert the current mode of production into a closed farm management system, corresponds to the percentage of organic farm managers who rear farm animals in an organic way as well (32.65%).

The aim of this study was to assess the status of the hydrotechnical torrent control works located in ten managed torrential valleys from Prahova County. The works were visually assessed by using a simplified version of the methodology developed in 2014 by the staff of “Marin Drăcea” National Research-Development Institute in Forestry together with the staff from Faculty of Silviculture and Forest Engineering from Brașov. The damages and disfunctionalities were recorded separately for the transverse and longitude structures. The inventory was done between 6th of March and 16th of April 2016. In total, 144 hydrotechnical works were assessed (3 evacuation canals, 17 sills and 124 dams). The main identified damages consisted in detachments located in the overflowed area. Regarding the identified disfunctionalities, almost three quarters of inventoried works were affected by the clogging in various degrees (ranging generally between 50-70%), located both in spillway and apron. The high percentages of damages and disfunctionalities are due, most likely, to the lack or low number of interventions of maintenance and/or repair, especially for works carried out in the sixth and seventh decades of the last century. These findings should be regarded as a warning both for the local and national authorities, but also for the administrators of the forest fund.

Treatment Tourism is a specific form of rest tourism, destined to prevent certain illnesses or diseases. This is one form of the constant movement of a tourist relatively stable clientele. The paper analyzes the main forms of tourism in the area, referring in particular to the spa potential and its recovery. The study analyzes the main forms of tourism in Mangalia, focusing on spa treatment and the resources available in the city for bathing cures. The data from the National Institute of Statistics, Department of Statistics Constanta, regarding the flow of tourists in Mangalia were used. The data were processed and converted into tables, graphs and then analyzed and interpreted. The study pointed out that Mangalia is visited by tourists four months a year (June, July, August, and September), and tourists who spent their holidays in Mangalia are both of Romanian and foreign origin. The number of tourists in Mangalia fluctuated from 210,000 in 2010 to 240,000 in 2014. The average length of stay is 5 days in sanatorium, like in the rest of spas in the country. Of the total arrivals in Mangalia, only 2% tourists have treatment tickets. Customer categories have the following structure: 35% retired persons, 25% people with secondary education, 25% persons with higher education, 5% artists and sportsmen, 0.5% other professions.
