An important problem, on which production and economic results depend for a long time, is the size of agricultural exploitations. The use of statistical methods, among which the one known as the "statistical method of studying the mass experience" or simply the "method of grouping", is the most widespread [10] in order to determine the optimum size of agricultural exploitations is based on the concept of statistical correlation, that can be attributed to the links between potential indicators (factorial or independent variables) and results and economic efficiency indicators (resultant or dependent variables) of an agricultural holding. The calculations show that the managers of the exploitations from the forth interval have made greater efforts to match the highest level of turnover and profit. How many? As far as the optimal number is concerned, it should be taken into account that the cost of production is more important to producers, as the sales price is formed under the impulse of the demand-supply ratio. In conclusion, the present study sets the optimal range related to the area of 3,801ha – 4,400ha and the optimal breeding females: 686 heads.

The present study is intended for the management of the analysed company, which is concerned with the increase of the efficiency of the activity. Labor productivity has increased from one year to another. The efficiency in using human resources is the way of observing some correlations between the main objectives and the results obtained from their realization. The study of certain correlations, at the level of the selected society, shows that biggest increase in turnover was obtained through labor productivity, therefore by intensive and not extensive means.

Food security, poverty and the overall sustainability of food and agricultural systems are influenced by a series of global trends. Nowadays, economic growth, population dynamics, and climate change disproportionately affect different regions. Conventional agriculture also contributes to accentuating these changes. As a result, we are faced with several challenges in the fields of food and agriculture. So, innovative systems are needed to protect and enhance the natural resource base as productivity increases. Consequently, today, but also in the future, the farming systems that counteract the negative impact of climate change must be in the attention of practitioners. Moreover, regulations in the field are necessary, and the implementation of such systems must be carried out in relation to the specificity of the geographical area. In view of the above, in the present paper, a brief overview was made on some agricultural systems aimed at counteracting the negative effects of global climate change.

The tradition of using medicinal and aromatic plants in Romania dates back to the year 1862. The purpose of the present paper is to identify the main medicinal and aromatic plants, as well as estimating the quantities that can be harvested from Dobrogea in 2018 from the forest fund managed by RNP - Romsilva, the National Forest Management Institute. As such, 21 medicinal plants were identified in the two forest districts (DS) from Constanța and Tulcea Counties. A quantity of 22 t of medicinal plants from 10 species was estimated for harvesting in DS Constanța, while in DS Tulcea the number reached 588 tones from 21 species. The largest quantities that can be harvested in DS Constanța are represented by locust (Robinia pseudoacacia) – 5 tones and elderberry (Sambucus nigra) – 5 tones, while for DS Tulcea they are represented by silver linden (Tilia tomentosa) – 180 tones, elderberry (Sambucus nigra) – 60t and nettle (Urtica dioica) – 50 tones. All the other species can be gathered in quantities ranging from 1 ton to 40 tones. Taking into account the natural conditions, Dobrogea region is characterised by a high potential of medicinal plants. The possibility that these natural resources are maintained and even developing future abundant populations is conditioned by the appliance of appropriate management measures that abide to the present laws, the species sustainability principle as well as the protection of endangered species.

The study was done in Ghana. The main objective of the study was to analyze the production, consumption and marketing stages of cocoa in Ghana. A qualitative research approach was adopted for the study. Theoretical studies and literatures related to the study were explored in gathering relevant data required to outline and analyse the attributes necessary for the enhancement of the production, consumption and marketing stages of Ghana’s cocoa industry. Secondary and qualitative data were reviewed and collected from research findings, literature, journals and other publications conducted by the United Nations FAO, International Cocoa Organization (ICCO), Ghana Cocoa Board (COCOBOD), and other individual researchers and organizations. The SWOT analysis revealed a good number of opportunities provided by the external environment and advantages in the internal environment that can be capitalized to enhance the cocoa industry in Ghana. A TOWS analysis matrix was constructed to determine possible strategies that can be adopted to manage the production sector within its environments.

The Syrah grape vine variety was introduced to us in the country relatively recently, after 2000, although in other wine-producing countries in Europe and even on other continents the wine obtained from it is highly appreciated. Syrah wines have strong character and personality, are tanned and strongly colored, with high alcohol content. Wines have floral (violet) or fruity flavour (raspberry, blueberries, blackberries, and dried plums etc.). Most Syrah wines have a great maturation and aging capacity, due to the compositional characteristics (mainly tannin richness), maturing, resulting in a complex aroma, spicy characteristic of black, red or green pepper, spices, olives, anise, etc. On our lands, studies about variety and Syrah wine are few and low significant, although in recent years there is already talk in the oenological field about very valuable Syrah Romanian wines assortment.

The study examined the technical efficiency of smallholder poultry farmers in Akure South Local Government Area, Ondo State, Nigeria. The study used a multi-stage sampling procedure to select eighty respondents with the aid of structured questionnaire. The primary data collected were analysed using descriptive statistics, budgeting analysis and the stochastic frontier production function model. Findings revealed that majority (65%) of the respondents were male. The mean age of the respondents was 40 years. About 66.3% of the respondents were married and majority (85.0%) of the respondents were literate with at least primary school education. The mean of farming experience was 7years, indicating that most of the farmers were new entrants into the poultry business. The findings indicated that poultry production by smallholder farmers was a profitable enterprise in the study area. The results of the stochastic frontier analysis revealed that farming experience, access to credit facilities, membership of cooperative association and extension contact influenced the technical efficiency of smallholder poultry farmers in the study area. It was therefore, recommended that government should work on providing credit access to farmers while also stimulating agricultural extension programs through educational and research institutions. Also, farmers should come together often so that they can pool resources together and easily get the government’s attention.

Genetically modified organisms have represented and represent, besides an obvious gain in scientific research, a great challenge for human communities to make the wisest decisions in achieving a fair balance between "gains" and "diversity" generated by GMOs, related to direct, indirect, immediate and delayed impacts developed on the short, medium and long term on human health and the environment. This article aims to analyse the procedure for the placing on the market of genetically modified food (feed and food) and to what extent a Member State can, in relation to European legislation, refuse / postpone the cultivation of certain genetically modified varieties on the basis of analysis impact on the environment, crops, or even has the possibility to prohibit the cultivation of these varieties.

African swine plague causes great economic losses due to the catastrophic depopulation of pig farms in the areas affected by their death and slaughter, by the implementation of approved sanitary measures and trade restrictions. African swine plague is a transboundary disease that can spread rapidly from one country to another and is one of the most dangerous diseases of pigs, being included in list A of „The World Organization for Animal Health (OIE)”. In this paper we analyzed some technical aspects related to the occurrence and evolution of African swine plague in the world and in our country. Due to the extremely rapid evolution of this disease in south-eastern Europe and especially in Romania, we considered it very important to analyze the economic aspects of this virus, especially the damages produced, and to see what the applicable European and national laws African swine plague and whether these normative acts have been enforced and respected in preventing the onset and transmission of the disease.

Siberian Federal District (SFD) is located in the center of the Russian Federation, occupying 30% of its territory. Its population is 19,326 thousand people, which constitutes 13.2% of Russia’s total population. The district consists of 12 constituent entities, which, to one degree or another, are engaged in agricultural production. Grain crops are grown in each of the SFD regions, with the way being currently led by Altai Krai, Krasnoyarsk Krai, Omsk Oblast, Kemerovo Oblast, and Novosibirsk Oblast, which account for 90% of the district’s gross grain output. Most of the district’s land under cultivation is sown to wheat (67%). However, due to unstable and low prices for wheat, agriproducers are forced to consider dropping some of the traditional crops and shifting, in accordance with the changing needs of the market, to other – sought-after and more competitive – grain crops. Another major issue in grain production within the district is the relatively low quality of grain, which diminishes its competitiveness in the market, with nearly 60% of all grain being represented by low-protein feeding grain. It may, therefore, be advantageous for Siberian agriculturists to grow grain for livestock farming, and this may require enhancing the actual structure of the land under cultivation and focusing on growing grain crops with the protein component greater than in the 4th class soft wheat. The paper shares some of the findings from an assessment of the region’s agro-climatic potential for the period through to 2025.
