EFFICIENCY OF APPLICATION OF BISCHOFITE IN THE CULTIVATION OF SAINFOIN SANDY IN THE LOWER VOLGA REGION
Dronova, T.N. | Zemlyanitsyna, S.V.
the article presents the results of studies on the effectiveness of the application of presowing treatment of seeds of sainfoin with chloromagnesium salt. Of particular interest are these studies because for the first time on the irrigated lands of the Lower Volga region, the complex effect of this technique was studied when cultivating a sainfoin on five agrochemical backgrounds: without fertilizer, with NPK injection, with manure, siderata and straw. The positive effect of bischofite on the increase in the fullness of sainfoin shoots was established. The highest was in the variant with a calculated dose of NPK – 63.7-68.1%. The maximum herbage density and co-preservation of plants was also noted on this variant – 86.9-93.1%, against 76.3-88.5% – on the control. The introduction of mineral fertilizers, the dung of manure and siderates, contributed to an increase in the accumulation of organic matter and on crops of the second year of life, in these variants without bischofite treatment in the 0.5-meter layer of soil, it accumulated from 6.1-6.3 to 6.3-6.5 t / ha dry roots, and with presowing seed treatment – 6.2-7.2 t / ha.Show more [+] Less [-]
