THE INFLUENCE OF CROP ROTATION OVER THE YIELD AND THE QUALITY OF THE SEEDS FOR THE DROPIA AUTUMN WHEAT CULTIVAR PUBLISHEDMariana Popovici, Eva Bucurean
The crop rotation has slow effects, which show their results in time, influencing the fertility through their structure and the alternant crops, mainly due to the effect of the precursory plant. Its action has a biological nature, which manifests itself in the quantity of the organic remains left in the soil, the root secretions, biological processes of discomposure and synthesis, all finally reflected over the yield. The precursory plants for the autumn wheat must respond to the following requirements: they have to clear the area as soon as possible during the summer, so there is left enough time to prepare the soil in the best conditions and for the realization of the sowing in time; they have to leave the area clear from weeds, with improved physical and chemical characteristics and with a high content of organic matter and nutritive substances. In order to emphasize the importance of crop rotation the quantitative and qualitative production of the Dropia autumn wheat cultivar has been analysed in the conditions of monoculture sowing, wheat – corn rotation and wheat – corn – pea rotation.
