The paper presents the doses of nitrogen necessaries for main autumn and spring crops in Banat Plain area. The data presented in this study were received from many farmers in the studied area. The most important crops in Banat Plain are: wheat, maize, sun-flower and barley, they were finding cultivated in the largest surfaces by local farmers. To establish the nitrogen doses it was taken into account the following parameters: expected yield in function of the specific consumption of the plant, the crop cultivated before, quality classes of arable lands and nitrogen uptake in the soil by manure. It might be find some errors in nitrogen doses mathematical account because not all the farmers form the studied area rapport their data. The nitrogen doses are expressed in kilogram active substance per year, for each crop. The largest doses of nitrogen were calculated for maize crop and the smallest for sun-flower crop. The obtained data after this research might be used in agronomical practice.
