Grapes produced in many provinces of Turkey, with the possibility to evaluate in different ways and also as an agricultural product which is also an important contribution to foreign trades. According to the latest data, Turkey ranks in fifth regarding the total vineyard area and sixth in grape production in the world countries. This study aims to reveal the economic analysis of grape production. In this framework, determining the economic structures, annual activity results of vineyards, and calculating the production costs in the case of Denizli province. It was determined that grape production mostly made in aqueous conditions and goble training production was done in non-irrigated vineyards. Because of this situation, according to the wired training vineyards, it was found that the yield was about 1.6 times higher than the goble training system. It was determined that the labour force was used intensively in both production systems. However, more labour was used in the wired training vineyards than in the goble training system. It was determined that the gross production value be higher in the wired training vineyards. According to these results, it can be said that the wired training system was more advantageous regarding economic criteria.

Natural dietary antioxidants are important for their ability to protect cells from miscellaneous damage. Grape seed (GS) (Vitis vinifera L., Vitacease) is a potent natural antioxidant. The present study aimed to investigate the protective effect of GS against the possible testicular dysfunction caused by Lindane in male rabbits. Eighty sexually mature NZW male rabbits (average BW: 2.150 ± 0.50 kg) were equally divided into four groups, the first served as negative control, the second received Lindane (L) (4 mg/kg body weight 1/ 50 LD 50), the third was supplemented with GS powder (50 g/kg diet), and the fourth received both Lindane and GS (LGS). Doses were given once daily via gavage for 90 consecutive days. The results revealed that, L group induced significant decrease in final body weight, sex organs relative weight, sperm concentration, motility and viability, serum testosterone concentration. Moreover, L altered the histological structure of the testis. Supplementation with GS ameliorated the harmful effects of L, this was also proved histopathologically by the noticeable improvement in the testis tissues. It may be concluded that GS may be promising as a natural therapeutic agent in Lindane -induced reproductive toxicity and oxidative stress in the male rabbit testes.

The primary role of agriculture is to produce food. However is the agriculture sector able to provide other activities? Exploitation of biomass and production of biogas from the waste of agricultural production shows that the farmer can become producers of energy. Two of the most typical agricultural countries in European Union are Slovakia and the Netherlands. This article was based to answer the question: What are the differences of using green energy in Slovakia and the Netherlands in agricultural sector? Comparison of information such as spread of land, population density, gross domestic product data on agricultural production, energy production and consumption in the agricultural sector showed that renewable energies are widely used in agriculture sector although approach in both countries is different, as a result of differences in the climate and geographical condition of these countries.

The price is generally a very important factor in taking the purchase decision; it will influence the acceptance or rejection of organic products. For those who believe market forces represent a path to sustainability, it is vital to include eco-costs in the product costs and, further, in their prices. Otherwise, consumption growth will result in a continuous degradation of ecosystems, taking into consideration that environmental costs are not reflected in the price. To what extent a company is considering the ecological policy will be reflected in its cost structure. Organic products, most of the times, will incur additional costs generated by preservation and improvement expenses for environmental. These expenses will be reflected in costs, the price will reflect the value of the main benefits required by the consumer.

The major aim of this study was to compare the gross and net profit of culture, cross and native-breed dairy cattle farms in Gevaş district of Van Province, Turkey. The required data belonged to 2009 production period and was collected from 44 farms by means of questionnaires interviewing the managers directly. Stratified random sampling method was used in determining the sample size. The number of cows per farm, daily milk yield per cow and lactation period were 3.15 head, 11.54 kg and 210 days for culture-breed farms; 4.0 head, 6.43 kg, and 210 days for cross-breed farms and 3.06 head, 4.21 kg and 215 days for native-breed farms, respectively. Daily feed intake per cow was 13.47 (9.88 kg roughage and 3.59 kg concentrated feeds) for culture-breed farms, 11.00 kg (9.66 kg roughage and 1.134 concentrated feeds) for cross-breed farms and 11.19 kg (9.29 kg roughage and 1.9 concentrated feeds), for native-breed farms, respectively. Feed costs consisted of 90.34, 89.11 and 84.59 % of total variable costs for culture, cross and native-breed farms, respectively. The cost of one kg milk was $0.49, $0.76 and $ 1.11 for culture, cross and native-breed farms, respectively. Gross profit per farm and per cow were $2,665 and $846 for culture-breed farms, $1,220 and $305 for cross-breed farms; $55 and $17.8 for native-breed farms, respectively. Economical profitability rate of culture-breed farms in terms of gross profit were nearly two times higher with 19.27% compared to that of 10.01 % for cross-breed farms. The economical profitability rate for nativebreed farms was only at 0.53% levels. Production elasticity of inputs (Σbi) was 1.66, which means increasing return to scale. In case of duplicating the inputs used, milk quantity is expected to increase by 1.66 times.

In this study, the geographical and local topographic factors have been incorporated into geo-statistical approaches and also various models have been developed relating hail events to site position to assess of a hail hazard at high resolution in the Republic of Moldova. An assessment of the average number of hail days, frequency of a year with hail incidences and peak values by natural zones of Moldova has been derived based on the hail incidence records for 68-years (1949-2015). Hail Sensitive Areas (HSAs) at high resolution are delineated to design resilience for coping with this climate hazards at community level. The research findings ensure more effective use of the hail data and better understanding climatology of hail risk across the Republic of Moldova, and, therefore, facilitate decision making and determination of hail insurance rates throughout the country.

The paper analyzed the impact of Romania's accession into the EU on honey production and trade, using the empirical provided by FAOSTAT and National Institute of Statistics. The methodology was adapted to the purpose of comparison between the pre and post accession period using fixed basis index, growth rate, absolute and relative differences, structural indices, specific trade ratios, and graphical representation. Romania is an important honey producer with a potential over 30,000 tonnes per year. The accession into the EU in 2007 has stimulated the development of apiculture. In 2017, Romania produced 30,177 tonnes honey of which, about 46 % was exported mainly in the EU. Romania has over 1,600 thousand bee colonies and 46,000 apiculturists, meaning 24 bee families per apiary. Honey yield per bee family is 18.8 kg, but the potential is over 22 kg, less than in other EU countries. Weather conditions have deeply influenced apiculture performance during the last decade. Both acquisition and producer's price increased in the domestic market, and also the export/import price index was favorable to Romania due to the high quality of honey which is much required on the EU market. In 2016, the export value reached USD 41.4 Million, being 5.37 times higher than in 2000, and the import value achieved USD 8.9 Million, being 52.5 times higher than in the 1st year of the study. Trade balance accounted for USD 32.5 Million, being 4.3 times higher than in 2000. As a conclusion, the accession of Romania into the EU favored honey production, export and import and helped the EU to meet much better its internal market needs and intensify export. For this reason, beekeeping will continue to be an important sector of Romania's and EU agriculture in order to support pollination of agricultural crops, food security and safety and preserve biodiversity. Due to the strong competition, Romania should fight to maintain its position as a top honey producer and exporter of the EU. For this reason, beekeepers should increase apiary size, include organic honey as a market niche, assure honey certification brands and join in more associative forms for increasing efficiency along the honey market chain.

The total forest area in Europe accounts for 215 million hectares. In Europe, forest management is done both by private-owned and state-owned enterprises, companies, agencies or other structures. The European State Forest Association (EUSTAFOR) represents a forum of 33 national forest administrators (NFAs) originating from 22 countries, that are managing 30 million hectares of state-owned forests. The main aim of this study was to compare the data provided by EUSTAFOR for the NFAs regarding the managed forest areas. Secondly, the share of managed forest area per employee was assessed for each of the 23 members for which the information was available on the official website. The NFA that is managing the highest forest area is Metsähallitus (Finland), with more than 9 million hectares. As regards the average annual harvested wood quantity, the NFA from Poland, namely LASY PAŃSTWOWE, is the leader, with more than 37 million cubic meters. Based on these results, it seems that the highest share of managed forests per one employee was recorded in the countries situated in the northern part of Europe, namely Norway, Finland and Sweden. ROMSILVA, together with the NFAs from Germany and England ranked on the last positions as regards the share of the managed forest area by one employee.
