【 摘 要 】

The Transylvanian Plain has a particular aspect, as the hilly areas are predominant and here the soil erosion phenomena through levigation are frequently encountered. The effect of water availability on yields has been thoroughly researched, being one of the main limitative factors of the winter wheat yields. Starting from these considerations, during the agricultural years 2012-2018, a bi-factorial yield test was performed at Agricultural Research and Development Station (ARDS) Turda, for a period of seven years. The study explored the influence of the water status under the influence of two tillage systems and the climatic conditions specific for this area on winter wheat yields. In the field conditions of Turda during experimental interval, the soil tillage system had a rather small impact on the winter wheat yields. In the conventional system (CS) a reserve of accessible water is preserved better during the spring period, this being attributed to a better infiltration into the soil of winter precipitation (snow). In the conservative system (NT), the observed trend suggests that restoration of the ground water reserve is more difficult than in the CS but the loss of water in the CS is just as fast.
