The way of preparing the ground for sowing the winter wheat is a decision that has to take into account at least some of the known elements: pre-emergent plant, soil type, water supply of soil and basic works performed in previous years. Nowadays, the practice of abandoning the wheat field is being extended, adopting variants of churn without turning the furrow or the variant of the stubble work only with heavy discs. The choice of corrected soil works in different conditions from one year to another requires a great deal of skill to ensure optimal conditions of emergence, which the present paper also pursues. Research should be expanded to follow how soil works influence plant growth and development. In this paper, we have presented the influence of the way of performing the basic soil work and the preparation of the germination bed on the wheat emergence. We have found that among the variants of basic soil work (ploughing, grubbing and deep disking) the best in our experimental conditions has been the deep drilling. Regarding the way of preparing the germination bed (with a disc harrow in an aggregate with fixed tooth harrows and a rotary harrow respectively), the results pointed out that by using the drill the number of plants/m2 increased "very significantly". The differences between the two experimental years were not big, since in both years the climatic conditions, mainly the water supply of the soil, were of high quality. It has been shown by a better „settlement” of the germination bed when using the drill has created better conditions of germination and emergence mainly due to better contact between the seeds and the soil particles and the faster restoration of the capillary network in the germination bed.
