Abstract
The experimental zone of the Transylvanian Plain is characterized by some particular problems for the maize crop due to an oscillating thermal regime; relatively shorter frost-free interval; climatic diversity; mixed relief; and soils with different peculiarities, even from one plot to another. This paper presents the results of research conducted during 2016–2021 regarding the influence of four soil tillage system and two fertilizer doses on emergences and maize yield, in the pedoclimatic conditions of the hilly area of the Transylvanian Plain. In all experimental years, a faster maize emergence was observed in the conventional-plow and minimum tillage—chisel compared to minimum tillage-disk and no-tillage. In a conventional system (control), the yield achieved (7603 kg ha−1) was close to the minimum tillage—chisel system (7529 kg ha−1), and higher than the minimum tillage-disk (6391 kg ha−1) and no-tillage (5178 kg ha−1). The beneficial effect of additional fertilization with CAN 27 (granular nitrogen fertilizer containing magnesium and calcium from dolomite) is found in a better development of plants and on the increase of yield with 356 kg ha−1 compared to the variant with basic fertilization. The yield difference between the two hybrids included in the experiment is insignificant (under 100 kg ha−1).
