The content and quality of proteins are genetically determined characters. Individual complex of soybean proteins determines the economic values of the species. In order to identify the particularities of plant response to humic compounds, the polypeptide spectrum of soybean proteins extracted from seeds of two varieties with different drought resistant was analysed. The comparative analysis of protein spectra of extracted proteins from beans of the control plants highlighted the presence of common polypeptides to both studied sorts, and the presence of specific polypeptides for each genotype with a varying amount share appreciated through colorant intensity and band dimension. Protein spectra included polypeptide bands with molecular mass comprised between 106 and 20 kDa. Notable qualitative differences between polypeptide pattern of genotype with medium resistance to drought (Horboveanca) and those resistant (S4-04) were detected at the polypeptide level with Mr 104, 60, 43 kDa, present in resistant genotype and absent in medium resistant. Under our previous research was established that treatment of seeds with humic compound (LG) significantly increase productivity of soybean plants growing under field conditions, which determined substantial changes in the protein content and enhance grain biomass. From the reported data we conclude that the chemical compounds such as humic compounds may influence production potential of soybean and resulted substantial changes in the protein complex of the plant.

The future of the rural world has been the subject of much research in Europe and a large number of reports have been written on this subject. For the European Union, which aims to support rural development, it is essential to precisely define what a rural area is and even distinguish several different types of rural area. Rural areas are facing major challenges today which arise mainly from globalization, demographic change and the rural migration of young, well-trained people. Policies for rural areas aim to contribute to recognizing and making use of strengths and opportunities. Innovations have a direct influence on the level of welfare and satisfaction of each rural citizen and whole society. EU policies concerning innovations are aimed at transforming the European Union into a leading economy based on knowledge.

Integrated protection represents a modern approach, denoting a protection strategy of agro-ecosystems; and it represents a complex system employing all appropriate methods in a manner as consistent and smooth as possible, in order to maintain the biocenotic balance of agrosystems and to keep pathogens at a level at which they do not cause economic damage (so-called level of eco-efficiency). A biocenotic approach to issues of agrosystem protection against disease attack requires an acknowledgement of all aspects regarding the evolution of pests in time and space, so as to be able to intervene at the right time with all possible means. And such protection measures are not supposed to restrain existing tendencies in the agrosystem. Therefore, this implies the awareness that any applied protection measures do not affect solely a certain pathogen, but the entire plant and animal community, as well as the soil and water.

The main problem facing businesses today is not the scarcity of goods, but the scarcity of customers. Most entrepreneurs can produce many more goods than consumers are able to buy. This overcapacity is a result of each competitor desire to increase market share at a rate impossible and causes, in turn, extremely high. This has led to increased role in the promotion and marketing activities due to increased management attention on export promotion.

In agriculture, a major benefit of satellite registrations crop is forecast problem by following up the development of crops in certain phenological stages. Then, the registration of pest attacks made possible intervention in the early stages of this phenomenon. Development of the Earth's surface registration techniques in different spectral bands, specialized for certain components of the environment. Such as those of the last LANDSAT and SPOT satellites were able to follow some aspects of forestry and agriculture

Nowadays natural resources have a controversial accounting treatment which is caused, firstly, by neglecting their inherent properties and, secondly, by a free and one-sided interpretation of the legal framework. The definition of natural resources is bad too, which also creates additional difficulties in accounting of the operations connected with the preparation for natural resources usage and exploitation.

Controlled growth in the laboratory of some species of insect’s are justified both scientifically and practically. Due to the economic importance that the corn crop pest Tanymecus dilaticollis Gyll. (Coleoptera: Curculionidae) had in Romania like the main pest of maize crops we tried to obtain successive generations under environment controlled of the insect mentioned. In this paper we aim to improve the efficiency of the multiplication of the species with respect to two aspects: attending larval and multiplication high efficiency. The coefficient value of 20, 90 obtained by us indicate a considerable increase in performance compared to previous attempts multiplication thus increasing your chances of recovery of this method of mass multiplication.

The factors that we took into account the following important elements: for goods and capital (brand promotion, reliable predictions against risk factors, knowledge capital, intangible values for hotels), for health and safety (the easily with which diseases can cross oceans and borders and multiplying rows of old and new infections, some impossible to treat, strict control of food and non-food products entering in the hotel), for new management (planning education and training process in hospitality industry, demographic problem, New trends in the workplace). One of the most dramatic changes in this industry is the way to sold products and services for public hotels. New technology, development of hospitality industry and social problems are very important, also in this process of change management to hotels.

Sustainable development and success of rural tourism and agrotourism not depends only by attractive tourist facilities and landscape, depends to an extent more or less equal competitive and quality service. Tourism, being known as one of the world's most competitive activities require commitment, professionalism, understanding, organization and not least an effective strategy for human resource development. The materials we will present the method used in the study was a questionable applied in Olt county, in the 9th joint distributed three forms of relief: Meadow: Gura Padinii, Gârcov and Orlea, Plain: Călui, Curtişoara, Pleșoiu and hill Leleasca, Oboga and Sâmbureşti, in order to analyze and agro tourism potential, to develop strategy and promote recovery. In evaluating the survey data used to test the association, (Chi, Hi or χ2 theoretically) test allows highlighting the existence / non-existence of a link between the association created under local segmentation variables studied.

The Corkscrew horns Valachian sheep it is a breed from the Early Egyptian (Ovis paleoegiptica) phileic group, located in Serbia, Montenegro, Panonia, and Romanian border with Serbia. The tribe was named by Buffon (1780), Darwin (1865) Valachian, by Serbs Corkscrew Horns Valachian (Valaska vitorogta), by Hungarian Racka (=Serbian), by Linnaeus O.a.strpsiceros. The translation of strepsiceros into German=Zackel (Nathusius 1890), produced a confusion with the Valachian philetic group descending from the Thrakian philetic group. To avoid confusion, we proposed (1994) to use for this philetic group the Serbian name Valachian Corkscrew Horns. It is a sedentary sheep, not adapted to transhumance and to big flocks, not adapted to support wintering in open field, even to stay in the rain. Have a smaller weight of fine fibbers in the mixed wool, it seem black colour recessive, inverse than in Valachia (Tsurcana) breeds. It is economically not competitive with others local and improved breed and it is in danger of extinction in Serbia and even Romania and well conserved in Hungary. It was considered as an historical document (Dunka 1984) and perhaps it is. Document the former existence of a Valachian tribe in this area, implicit the Valachian contribution to the ethno genesis of nations from this area. As an interesting genetic resource, but also for the aesthetic aspect of his horns and for some cultural reasons it deserves to have a good genetic conservation program.
