The Perception of Viticultural Landscapes as a Method of Promoting and Supporting Local Economic Activities Through Multifunctional Landscapes

Abstract The perception of landscape and consumption behaviour in relation to landscape was estimated using a questionnaire-based survey with 17 photographs: 15 photos from Romanian representative landscape units, 1 photo representing a foreign landscape (Hungary), and 1 marketing photo. The photo documentation was conducted in sixteen vineyards ecosystems from Târnave Viticultural Region - Transylvania (NW-Romania). The most representative landscape was the photo that had the specifications and criteria: low practices intensity with low landscape complexity; and the less representative landscape was the photo that had the specifications and criteria: photo capturing hiking, walking, tourism, and recreational activities in a viticulture landscape. The landscape could influence the following aspects of communities’ livelihood: establishments and development of enterprises, tourism and recreation businesses, and the place to live. The words used by interviewed people to point out the landscape were interpreted from the point of view of the concept of multifunctionality.

STUDIES REGARDING THE INFLUENCE OF IRRIGATION ON FRUIT YIELD AT APPLE TREES IN IARA - TURDA, TRANSYLVANIA CONDITIONS

The paper presents the results of the experiments that were carried out during 2012-2014 period, in the Iara-Turda depressionary area conditions. The research`s general objective is the study of agroproductivity at Jonagold, Florina, Generos, Idared, Jonathan, Granny Smith and Golden Delicious apple varieties, all grafted on to a semi-vigourous M106 rootstock. The influence of the irrigation and fertilization regime was studied in an polifactorial experiment that aimed the study of the interactions of three factors and the specific and cumulative effects on growth and fructification parameters of the apple tree varieties in the pedoclimatic context of the studied area. The present paper refers only to the interaction and effect of the irrigation regime in relation to the studied factors.

Researches regarding the influence of irrigation on vitamins content at celery (Apium graveolens var. rapaceum)

The paper includes some results of the investigations held between 2009 - 2011 in the conditions Nicula - Gherla, Cluj county, the influence of factors of production (irrigation regime, fertilization, biological material) on the content of vitamins (B6, B9 and C ) at the celery culture. It was found that the best results, respectively a higher vitamin content was obtained in irrigated variants at a humidity threshold of 80% of active moisture interval (AMI).

THE CELERY CULTURE IN THE CONTEXT OF DEJ AREA CLIMATE CONDITIONS

In the present work is realized a complex analysis of climatic conditions in the agricultural Plain of Transylvania, in the context of climate change, which is one of my biggest threats in terms of environmental refering to socia l and economical aspects.

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.

STUDII PRIVIND EFICIENŢA ECONOMICĂ A IRIGĂRII LA CULTURA DE PORUMB ÎN CONDIŢIILE DIN TRANSILVANIA

Studies regardind the economic efficiency of irrigation on corn yield in Transilvanian conditions. The corn is one of the plants that reacts advantageously upon irrigation. Through approached themes, the research team intended to bring a contribution in order optimize some elements of the corn culture technology, on the corn grains of four Pioneer hybrids recently introduced in culture, relating to irrigation regimen. The research was effectuated in specific conditions of the under wet hilly zone in Transylvania, and regarding a maximum economic efficiency.
