Agriculture is presented in all counties of the region. The region has favourable natural conditions and an important potential for the agriculture development. Agriculture in Romania has its natural, economic-traditional particularities that can be used in order to obtain some competitive advantages, the European Union encouraging these evolutions. At present, in agriculture in Romania there is a poor link between the farms with the market and a production structure that corresponds to the market demand. That is why, in order to highlight some strategic elements of the rural development, related to the agricultural activities in South-Muntenia Region, aspects regarding the structures of the farms, the structures of the crops and animal breeding must be taken into consideration. The present paper presents aspects regarding the farms in South Muntenia Region. The agrarian structures are the expression of evolution/involution of the agriculture and of the rural area, that balance the economic and social development as a whole. The reduction of the level of agricultural surfaces fragmentation and the stimulation of small size farms concentration constitutes an elements of the evolution of the agriculture and of rural area, the European agrarian policies having as objective the decrease of structural discrepancies of the farms. The limits of the farms were also defined under the average surface of 2-9 hectares, that define the small size farms, under these dimensions being considered family farms.

Sea buckthorn is called by the Romanian peasants “berries of the Holy Virgin”. They use from hundreds of years the fruits for health problems. From fruits they are obtained many products in feeding. Romania had great specialists in forestry, horticulture, medicine, bio-chemistry with many studies and aplications of sea buckthorn. In Romania Hippophae rhamnoides L. was the object of many national research programs. Now there are not serious investitures and are not mobilized foreign institutions which may use modern instruments for the obtaining all advantages of this plant. Some institutions, industrial units, particulars continue the tradition with good results, that is not the level which is possible in the actual potential of Romania. It must be a solution of the rehabilitation of thousand of hectares of Romanian denuded grounds.

Management of organic waste is a difficult, complex and intractable in Moldova, according to international standards. Acute problem of organic matter from livestock sector waste is generated by storing them in unauthorized areas. Organic waste management strategies require different methods. One of them is organic waste bio conversion technology by worm’s cultivation. As the main natural wealth of the Republic of Moldova, soil requires a special care. Agriculture, in particular, should pay attention to the soil’s humus and nutrient status – and restore losses of humus and the nutrients used by crops. This requires measures to improve soil fertility. Land use provides, first of all return losses of humus and nutrients used by plants. Therefore measures required to improve soil fertility. The essence of the research was to highlight the role of worms compost improve the soil. To this end, in ETS "Maximovca" was organized an experiment that included three groups (two - experimental, to fund worms compost and one - control the natural background). Observations on soil fertility have been conducted over three years. The soil samples were collected by usual methods determined values of organic matter and humus. The results of the investigations, to determine the values of organic matter and humus samples collected from surface and depth 15 cm exceeded that of the sample control group to 29,7%; 11,4% and 34,3%; 37,1% in experimental group I and 9,3%; 11,6% and 45,5%; 45,5% in experimental group II. Therefore, worms compost embedded in a dose of 3-4 tons / ha during three years, has improved the fertility of the soil

This paper presents the calculation regarding thermic transmision through the closing elements made for a greenhouse designed for salat production, pea, spinach and cabbage, D.M. greenhouse type, with medium and large openings (12...30m) having a light roof with spatial structure from bars and thin walls made from galvanized steel or aluminium and designed at the Technique University from Cluj-Napoca. The greenhouse opening is 15.90 m, the total lenght is 40.50m and 669.53 sqm surface with 643.95 sqm usable area. After analyzing the thermal calculations for the production of vegetables greenhouse show that the heat losses are insignificant, advantage is given by the light roof with spatial structure from bars and thin walls made from galvanized steel or aluminium.

Irrigation return flows increase the salt concentrations of receiving water bodies and cause water logging which affect agricultural productivity in Turkmenistan. Flooding irrigation drainage water using on natural pastures has also had adverse effects on the long-term productivity of desert ranges. This study examines the economics of halophytes as feed for sheep using saline irrigation water from drainage collector systems on a representative farm. Cost-benefit and rate of return analyses show that the project is economically feasible for reused water with 1400 mg/l mineralization levels or less. At higher mineral concentrations in water, or in more saline soils, bioremediation through halophyte fodder production can be profitably implemented if new market incentives exist. Value chain analysis is applied to evaluate alternative incentive systems for sheep operations based on saline water irrigated halophyte fodder production.
