COMPARATIVE EXPERIMENTAL RESEARCH ON THE QUALITY OF THE WORK OF THE COMBINED EQUIPMENT FOR SHREDDING AND INCORPORATING VEGETABLE RESIDUES COMPARED TO THE AGGREGATE SHREDDER OF VEGETABLE RESIDUES WITH THE U650 TRACTOR

In practice, the operation of destroying plant residues is carried out separately, in general the equipment is mounted on the back of the tractor. Equipment for destroying plant residues such as cutters, platforms with rotors, shredders, etc. is known. which works in aggregate with the tractor. The disadvantages of these equipments consist in the fact that they work independently and only carry out the operation of destroying plant remains and leaving them on the ground, in the technology being the additional passage on the same land for incorporation, which involves fuel consumption, pollution. ground subsidence etc. The combined equipment for shredding and incorporating plant residues eliminates these disadvantages, mainly because the operations are performed in a single pass. The advantage of using this mechanism consists in facilitating operations and increasing productivity with reduced time and fuel costs, at the same time meeting environmental protection requirements by reducing land subsidence and noxes produced by double tillage. Another advantage consists in avoiding the accumulation of plant debris in front of the active organs of the plow and removing it from the furrow, in case the unshredded material would remain on the ground

ASSESING THE IMPLEMENTATION OF REAL CONVERGENCE IN ROMANIA

The convergence is an essential objective of the integration process of Romania in the European Union. Minimizing gaps in the level of development that arise between Romania and the average European Union can not be achieved solely through the use of marconvergence, European Union, real convergence

Influence of Phosphorus and Nitrogen on Mycorrhizas in Winter Wheat

Intraradicular installation of vesicular-arbuscular mycorrhizas on the roots acts to amplify growth and to increase potential yield. Extraradicular network of hyphae developed by mycorrhizas acts as an extension of the root in order to access the nutrients located in unexplored areas. The percentage of roots occupied by mycorrhizal hyphae fluctuates heavily under the influence of fertilization. The highest values of the colonization parameters were recorded with a high level of phosphorus fertilization applied as phasial input. High doses of mineral fertilizers with phosphorus applied with seeding favors the development intraradicular hyphal networks in wheat roots.  Â
