The efficiency of the autumn wheat crop requires the application of some general technologies, but improved with innovative and specific technological sequences, depending on the evolution of the vegetation cycle and the expected production components. The researches were performed during the 2020-2022, in the experimental field of NARDI Fundulea and aimed to study the influence of agrotechnical practices on the yields and quality of wheat. The paper presents the results obtained in experiences with sowing dates and plant density, under non-irrigation condition, in the south of the country. Recording a stable and high production of autumn wheat is possible if a good sowing quality is ensured and the optimal sowing interval and plant density per m2 are observed. The variability of individual productivity of wheat plants can increase with the delay of the sowing date by up to 10-20% for the number of grains/plant and between 10-25% for the weight of grains/plant, and these lead to a decrease for production per hectare with 1000-3000 kg/ha. The variation of climatic conditions influenced negatively wheat yield and quality.
