THE INFLUENCE OF THE APPLICATION OF SOME NEW TYPES OF CALCAREOUS AMENDMENTS ON SOYBEAN PRODUCTION AND QUALITY, IN THE CONDITIONS OF SCDA PITEȘTI IN 2021

Abstract

Given the importance of soybeans, both in our country and in the world, it is necessary to expand the areas in different environment. In the conditions of the clay-illuvial soils of the station, the promotion of soybeans involves first of all the restoration of the culture medium and the chemical properties, considering the acid reaction which is totally unsuitable for the roots of the plant. To this end, an experience has been set up to promote the latest amendments based on calcium carbonate approved by us. Thus, the experiment promoted agrocalcium products - based only on CaCO₃ and doloflor with CaCO₃ and MgO (magnesium oxide). From the obtained results it was found that compared to the unfertilized control, the soybean plants produced total biomass of 9-11 t/ha, the biomass of the pods between 5,5-7,4 t/ha (over 60%) and the biomass of the grains between 3- 4,3 t/ha (over 30%). From a qualitative point of view, the Raluca TD soybean variety contained in the grains 36% protein, 25% oil, 6% fiber at a grain humidity of less than 10%. The data obtained showed a good adaptability of the new soybean variety in the conditions of the station.
