The purpose of this work was to evaluate the impact of soil tillage, sowing period and mineral fertilization (NPK) on the quantity and quality of the seed harvest, in the specific climate and soil conditions of the Arad Plain, more precisely in the chernozem microzone of Nădlac, Arad County. The use of ploughing in association with disc harrow determined a small and insignificant increase in production compared to plots where only disc passes were applied. The results obtained demonstrate the superiority of the tillage variants without furrow turning, compared to the classic tillage system by ploughing. Sowing in the period 25-30.IX and staggered in 06-10.X, did not attract, on average over the two years, any particular differences between the variants. Mineral fertilization (NPK) of the soil plays an essential role in optimizing the plant's nutrition requirements and achieving increased production. In addition, the tillage system and fertilization also influence soil fertility in the long term, a significant impact on other components of the environment. The variety of barley taken into cultivation was Melia.
