After Latvia has joined the EU, all the positive social and economic changes make us to believe that students' personalities will be developed in the same positive way. Of course it should be admitted that any changes in young personalities can be strongly affected by the university study course, its aims and content. Joining the EU allowed many Latvian students to use the possibility of studying and working abroad, and many of them are already using this chance not even thinking about the future of their native region. The majority of LUA students come from province as do many more from other higher schools but they differ from other higher schools but they differ from the previous generations with their more dynamical and free vision and more constructive actions. At the same time the idea of students' responsibility and upbringing their sense of affiliation to their native regions becomes more relevant. We investigated students' awareness of responsibility and civil maturity. The attention was paid to the development of students' patriotic attitudes during the acquisition of the course of studies at the institution of higher education. It is very important how a student's matured personality was developed. Love to the motherland was emphasized in Latvian pedagogy in pre-war years, but in our higher schools the idea of patriotic upbringing still remains at the very low level or sometimes does not even exist. The main objective for the higher schools management is initiating this process overwhelming student's drift away from their native district. The innovating rural tourism course for higher schools can be regarded as one of the possible instruments of patriotic upbringing.

The school's education surrounding is the places where social experience and children's learning opinion are gathered develop the system of attitudes. It values actualizes education's needs and develop the motivation of self-realization and develop motivates to continue the education. It is important to develop the skills to make a prognosis, to plan and to project the future. The aim motivation must be the real key in this process. The education of career is the school especially the main thing for rural schools that provide the long-term development during the crisis of demography and competition. The authors offer: 1) the typical needs of pupils for education in the surrounding of education, which is based on ecological approach in education and stresses the link between the surrounding and man in the holistic way, 2) the analysis of done investigations and evaluation in the part of discussions analysing the approach of career's education problems in the rural school, giving the references to other authors' views and investigations.

In XX century, educational dialogue is researched as educational and pedagogical method. The rural music schools of Latvia are good basis for scientific investigation. The aim of the research is to study situation of the educational dialogue in Latvia rural music schools and to analyse pedagogical aspects and authority, constructing progressive environment in understanding between individuals. A two thousand year's dialogue shows perspective way for best communication and cooperation. Dialogue idea in XX century philosophical and pedagogical theories is analysed in M. Bbuber, M.M. Bakhtin, P. Freire and N.C. Burbules works, and they have played an important role in the development of dialogue theory as a pedagogical problem. Dialogical interaction can provide to higher motivation of ensemble play lessons and to solve transportation and large way distance difficulties in Latvia rural areas.

The research was done to observe open-field cultivation potential for growing melons Cucumis melo L. without covering in two regions of Latvia: Tukums and Cesis. Three varieties of melons 'Zolotistaya', 'Galiley' and 'Kolkhoznica' were used. In all, 15 individuals of each variety were grown at each place - Tukums region and Cesis region. To evaluate growth and development intensity for each variety in each region, the following parameters were measured parameters were measured: length of the main shoot, number of leaves per plant, time of appearance of the first male and female blossom, and number of perished plants. The most suitable variety for the Cesis region was found variety 'Kolhoznica', but for Tukums region - 'Zolotistaya'. The research suggests that variety 'Galiley'is the least suitable for growing in both regions. It was established that successful open-field cultivation of melons in Tukums and Cesis regions is possible only in case of favourable weather conditions. In the year of the investigation, 2004, insufficient sum of effective temperatures limited successful development and yielding of melon.

In order to get maximum economic effect, when setting a solar collector in a peasant yard, it is important to choose the correct place. The yield of obtained heat energy will be at its maximum, if the temperature of surrounding air and solar radiation are higher by the relative humidity of the air - lower. To define these parameters, a special device 'Meteorological Device' (MD-4) was developed. The device was supplied with a mechanism which tracks the sun all day round. So the direct solar radiation on the surface perpendicular to the sun beams was measured. The second measuring of the solar radiation was made in relation to the surface, which was perpendicular to the sun beams only at the middle of a day time. For the measuring of the air temperature and relative humidity, corresponding sensors were used. In every 15 minutes the data of these four meteorological parameters were automatically measured and the results were saved into a logger - the device for data accumulation. After a certain period of time the information was brought into the memory of a computer and analysed.

Fuel as the main energy resource in agriculture and forest production is surveyed in the work. Specific weight of fuel and lubricants in applicable expenses in country farms is analysed, average fuel and oil consumption in farms of different specialization, as well as changes in oil price in farms of different size and specialization are shown.

The main parameters of the plough body that determine the ploughing efficiency are the initial and the final soil trip lifting angles on the share-mouldboard surface, the angles of its horizontal generatrix, the radius of this surface, and the working width of the body. By using analytical correlations derived as a result of theoretical research, a computer algorithm has been worked out for simulating the functions of the plough body and the forces exerted by soil upon the operating parts, as well as its draft resistance. These correlations allow to determinate the forces acting on the plough body and its draft resistance depending on the share inclination angle, as well as to evaluate its impact on the ploughing efficiency: energy, and the fuel consumption, and the quality of work. By increasing the initial lifting angle epsilon, (inclination angle of share toward furrow bottom) the draft resistance increases. For economical ploughing, the initial lifting angle of the soil strip must have a minimal value, its optimum may vary 28...32 deg. The use of bodies having optimal parameters allows obtaining good ploughing quality, reduce draft resistance by 12...20% and to raise correspondingly the efficiency, to save fuel and financial resources for ploughing.

The development of the water management economy must satisfy the demands of the society and create the assumptions for a balanced development of the Lithuanian economy. Therefore it is essential to develop a politically independent, innovative and effective water management economy, which shall ensure the supply of the continuous, long-term and accessible services of water supply and wastewater management, socially necessary to all users, the quality of which shall meet the provided requirements. Lithuanian economy has been evolving towards the market economy for the entire decade after the restoration of the independence in 1991. The situation in water supply and maintenance economy was complicated: water management economy in most localities was worn and economically ineffective, wastewater treatment equipment was physically and morally outdated. After joining the European Union, it was required to harmonize the national requirements with the legislation of the European Union: the core attention in the water management sector had been given to the implementation of the Directive of the Common Water Policy. The implementation of the European Union requirements in the water management sector required big financial investment. The objective of this article is to evaluate the investment into the water management sector in Lithuania. The European Union, the international financing institution and national sources are the main resources for the financing of the development of the water sector. In 2000-2003, the subsidies and grants from the aforementioned organizations amounted to 1,169.92 thousand LTL in order to improve the assimilation of the investment, it is essential to increase the pay-back of the water management sector, modify the current management, administration and control structure of the companies in the water sector.

In the paper there are described problems of sewerage system in Riga which essentially impede its normal functioning. There are analyzed operation regimes of two principal pumping stations which pump all wastewater of Riga to the purification plants (2001-2005). The main focus is on implementing different measures that would improve collection and pumping of wastewater. It is offered to build a third penstock from the Voleru chamber to the purification plants. It is suggested to separate the rainwater from the household wastewater. There are analyzed 11 different versions of pump operation. In the conclusions and recommendations the formation of the possible dangerous situation during heavy downpours is demonstrated. It is recommended to build a regulation reservoir near the purification plants which could essentially protect the Daugava from unpurified wastewater during the downpours.

In 1999-2003, the investigations were carried out in Juodkiskis study object of Water Management Institute of Lithuanian University of Agriculture. Study scheme is composed of three treatments: treatment I -slurry applied, treatment II - mineral fertilizers applied; treatment III - no fertilization. Test field is drained, drain spacing is 15 m; draining depth is 1.2 m. During the crop rotation the following plants were grown: spring wheat with undercrop, red clover (1st year of use), red clover (2nd year of use), sugar beet, and spring rape. The objective of studies was to determine the effect of cultivated crops on drainage water quality. As the study results have show, N total concentrations contained in drainage water increased due to higher fertilization rates and inorganic nitrogen accumulated in the soil. Neither fertilization nor amount of mobile phosphorous contained in the soil made any effect on Ptotal concentrations in drainage water. In arable land, Ntotal concentrations contained in drainage water were 2.3 times higher than those in drainage water of the field, where red clover was grown. Ptotal concentrations were higher in the field with red clover. According to the rates determined in Lithuania, drainage water is not polluted with phosphorus, while average annual Ntotal concentrations exceeded the maximum allowable (MAC) when spring wheat with undercrop and sugar beet was grown.
