COMPARATIVE RESEARCH ON WHEAT AND CORN CROPS ON A REPRESENTATIVE SOIL FROM TRANSYLVANIA

Promoting during the last decades of sustainable agriculture and sustainable concepts entails the application of the principles that lead to productive agricultural technologies, technically and economically efficient solutions with effective protection of the environment and consumers that ensure not only productivity but also real optimization of production, social and environmental components and causes a new quality of life. In this study was tracked the effect of the nitrogen-phosphorous interaction in achieving wheat productions. The current research is based on the production results obtained on corn crops (Turda STAR Variety) and wheat crops (Dumbrava Variety) – cultivated following corn, in long term experiments conducted on an argyle chernozem soil in Turda (Cluj County). The production data are obtained from these experiments, which hold objectives that target both the effect of differentiated fertilizations on wheat and corn productions and also the impact of fertilizers on the soil fertility evolution, on the quality of the productions obtained. The goal of this research is to present the differentiated fertilization systems involved in obtaining high productions in the reference area. In this study it was track the effect of the nitrogen-phosphorous interaction in achieving wheat and corn productions. The research presents the stated results as annual (partial) values and as being reference values for further experimental years.

RESEARCH CONCERNING THE EFFECT OF A FERTILIZATION SYSTEM ON WHEAT CROPS ON A REPRESENTATIVE SOIL IN THE TRANSYLVANIAN PLAIN

The research is based on the production results obtained on wheat crops cultivated following corn, conducted on an argic chernozem soil in the Transylvanian Plain. The goal of this research is to scientifically and agrochemically substantiate the differentiated fertilization systems involved in obtaining big productions in the reference area. In this study it was tried to track the effect of the nitrogen-potassium interaction in achieving the productions obtained in 2011 and 2013. The obtained results present the production levels obtained for wheat crops (Dumbrava kind), the prior crop being corn. The already existing and further research will enrich the study’s utility in taking a rational fertilization decision based in the future also on the support of the suggested solutions. The presented data hold originality, according to which the suggested solutions become important and they also present a real efficiency in the fertilization practice and technologies applied to wheat crops.

ECONOMIC EFFICIENCY OF LETTUCE CROP IRRIGATED THROUGH DIFFERENT METHODS

The research purpose of this paper, was to determine the economic efficiency of irrigation on lettuce cultivated in a protected area, while aiming to attain early crops of high quality, at low specific costs. From an economical point of view researches showed that micro-sprinklers irrigation is recommended. Though the yields are lower using this method, they are enough to determine a higher gain.

LANDSCAPING A PRIVATE SPACE, CUBLEÅžUL SOMEÅžAN VILLAGE, CLUJ COUNTY, FOR SUSTAINABLE DEVELOPMENT OF RURAL AREAS

The multiple functions they perform in all urban and suburban structures, green spaces, help improve microclimate, recovery and highlighting the natural environment and to correct its deficiencies, remedy or annihilates the negative impact of harmful and participate directly in addition to groups of buildings. Instrumental in achieving ecological balance of human ambience, you have harmonization mutual relations between built and open spaces and planted between spaces Manmade site and surrounding territory. Human intervention puts the seal today more or less to the farthest corners of nature. This intervention makes it desirable and how functional and aesthetic quality of nature and appropriate balance between it and built spaces, makes it desirable to respect for landscape architecture.

NATURAL AND ARTIFICIAL ELEMENTS USED IN LANDSCAPING A PRIVATE SPACE FOR SUSTAINABLE DEVELOPMENT OF RURAL AREAS

Manmade landscapes are made up of natural elements and artificial elements. Some natural elements such as macro-relief elements, hydro-geological, climatic conditions, astral light etc., cannot be changed under direct human intervention, this adaptation conditioning design solutions. Natural elements that can be changed are: watercourses, swamps, rocks, soil and vegetation. Artificial elements, constructed, functional and decorative are: roads, streets and alleys, pavilions with different destinations, playgrounds etc.. Natural features of the land are exploited, model, supplemented or corrected in order to create, redevelopment or change of scenery. The private garden is located in the village Cubleșul Somesan, being identified plot number 80 consists of three parcels totaling 10,800 square feet with one hand and another group of houses and households semirural type.

Estimations of Soil-Plant-Climate Relation in the Conditions of the Transylvania Fields

Determining the relation of plant - soil - climate and determining of each parameters, means to establish and develop a rational exploitation and sustainable agriculture system, having in the end of the vegetative periods a positive ratio between inputs and outputs, without high losses. The cultivable land and production registered a significant extension in the last years, but compared with the European Union benefits from agriculture exploitations, the Romanian agriculture systems, need to be improved and develop more rational. Soil moisture is important for forecasting both temperature and precipitation. As the temperature rises the evaporation rate of soil moisture increases. The increased soil moisture evaporation helps cool the ground. The researches were performed on a cultivable land from Plaiuri Field, Cluj-Napoca County in a bi-factorial experiment. Three graduals at the A factor – irrigation regime and five graduals for B factor – variety were followed. The soil offers the most stable variables, plant needs could be estimated and stabilized, and climate offers the most important elements for a normal evolution of the plant, typically for the variety.
