RESEARCH FOR ESTABLISHING THE OPTIMUM SOIL TILLAGE OF THE PRELUVOSOIL FROM ORADEA
Journal Title: Natural Resources and Sustainable Development - Year 2015, Vol 5, Issue 1
Abstract
The paper presents the importance of the soil tillage in maize technology. The researches carried out at the Agricultural Research and Development Station Oradea in the long term trial placed on in 1995.Comparativ with the variant with plough land of 25 cm depth in the variants were the most important soil tillage was with chisel, soil tillage work with roller disk or with plough land of 12 cm depth, the degree of soil compaction has increased; resulting porosity values decreased and the resistance to penetration increased. The highest differences were recorded in the variant worked with a roller disc. At maize crop the best option for basic soil tillage was with autumn plowing executed at a depth of 25 cm. In all other variants studied were losses of yield highly statistically significant in both years studied ; the higher losses (-62% in 2012 and -72% in 2013) were registered in variant worked with roller disc.
