Influence of tillage tools on agrophysical indicators of soil fertility and rice productivity

Under the Kyzylorda region, the zonal technology of the tillage system for rice provides for up to 8–10 passes of various units in the same field. The technologies used are often based on the use of obsolete machines, which leads to many negative developments. According to the scheme of field experiments, a traditional plow PLN-5-35 (control) and a swing plow Lemken Juwel 7 have been studied during fall plowing. It was found that the use of the Lemken Juwel 7 swing plow contributed to base on, obtaining the ridges coefficient of 1.09 due to the same size and shape of the layers and their location at the same distance, while in the check this figure was 1.15. The use of the Lemken Juwel 7 swing plow and the Horsch Terrano 4 FX cultivator in the tillage system of meadow-boggy soils for rice in the conditions of the Kyzylorda region contributes to an increase in yield by an average of 0,71 t/ha.
