The ecological frame from the Transylvanian Plain is given by the existence of interaction among a great number of factors, of which two are very important for the agroechosystem: i) the first is the thermal background with high time variations and low rainfall, characteristics which impose significant restrictions for crop plants; ii) and the second is the hill orography, with slope fields. The purpose of the research made is to establish the influence of the soil tillage system (conventional and no-tillage), the fertilization system and the phytosanitary treatments applied, on the accumulation and water preservation in the soil, on the degree of weeds in the case of autumn wheat crop and the production. The restoration of water reserve in the soil in the no-tillage system is more reduced than in the conventional system, but also the loss of water in the conventional system is as rapid. This loss of water is due to a more intense water evaporation in the conventional system, without vegetal debris at the surface. The degree of weeds in the case of wheat in the conventional system (with plowing) during the experiment (2012-2016) is more reduced compared to the no-tillage system. The average production of wheat recorded in the no-tillage system during the five experiment years is 6234 kg/ha, compared to the average production obtained in the conventional system, that is 6162 kg/ha, which indicates the suitability of its cultivation in the no-tillage system.
