RESULTS OBTAINED FROM MAIZE PRODUCTION DURING THE PERIOD 2012-2013 IN MINIMUM TILLAGE, AT ARDS TURDA

Minimum tillage systems on soil chasing the conservation and efficient use of natural resources, biological and water. By surrendering to plowghing with moldboard plow  in whole or in part by streamlining periodic tillage and keep at the ground surface of at least 15-30% of all plant debris, protect soil the  sheeterosion, it also eliminating  at the same time the phenomenon of soil compaction. A proper crop rotation is alternating in culture plants with strong rooting with shallow rooting plants, leguminous plants  have favorable effect for the successor cultures, soil nitrogen impruvement and contributing to the development of the root system. In research conducted at ARDS  Turda  on  2012-2013, in the cultivation of maize in the system with minimal compared to classic productions obtained system reflects the fact that maize is still a pretentious plant both climatic conditions and approach towards soil requirements. The influence of the year are very strong for corn production , he differences being of 689 kg/ha in the variant with a seeding and fertilization along with 414 kg/ha in the variant with additional fertilization. By applying minimum tillage system soil aims primarily to combat soil erosion and water retention in the soil so it is so specially important to watch the long term effect of applying them to the environment.
