Sustainable development is difficult to be achieved in mountain regions because of their sensitivity to climate change. The rapid development of mountain tourism worldwide during the last years makes the goal for sustainable mountain tourism even more challenging. Key factor to the development...

The purpose of this paper is to evaluate the soybean yield obtained from the application of the additional fertilization and economic efficiency determination. Experimental factors: Factor A - the fertilization: a1-N20P20K0 (100 kg/ha), applied simultaneously with sowing, a2-N20P20K0 (100...

Countries with the highest labor productivity overwhelmingly lie in the world's temperate climatic zones far away from the equator. The question we address is whether climatic conditions as measured by distance from the equator remain correlated with labor productivity after other variables are...

The purpose of this paper is to evaluate the degree of dicotyledonous weed species of maize culture, the effectiveness of weed control products and the evaluation of maize yield. Experimental factors A-treatment variants: a1-pre-emergence herbicide with Tender 1.5 l/ha + Merlin Flex 0.4 l/ha...

This paper represents an analysis of the way in which the potato-growing areas and yields obtained in Covasna County have evolved, compared to the situation existent at national level. In the introduction and in the first part of the paper, the global and European situation is also mentioned,...
