THE IMPORTANCE OF APPLYING SULPHUR IN THE PRODUCTION OF ECOLOGICALLY PURE PRODUCT OF ARTICHOKES
Research revealed that for the optimal variants, where the ratio of nitrogen to sulfur is about 1:0.25 and 1:0.30 content of nitrate nitrogen in leaves and other organs of plants of globe artichokes is reduced by half. As the authors on the content of nitrate nitrogen of the plant the last two options as in the typical gray soils and meadow soils, are close to each other and from the point of view of economic efficiency, the optimal ratio of nitrogen to sulphur for typical gray soils are considered equal to 1:0,20, and for meadow soils 1:0,25. In this regard, according to the authors, the introduction of sulfur to the soil in optimum doses reduce the content of nitrate nitrogen in tissues of plants of globe artichokes, respectively, production of ecologically clean products of this culture. It should be noted that in the typical gray soils and meadow soil with increasing doses applied to the soil sulfur also increases its removal from the soil, especially in meadow soil than in the typical gray soils.
