| Abstract | The results of studies on weed infestation of soil and sowings under the different agricultural crops depending on the basic processing systems and levels of soil fertilization in five-course rotation are presented. Found that in the conditions of Central Forest-Steppe soil weed infestation during the period of sowing and harvesting is the lowest on the background of the combined treatment, and the highest during systematically subsoil tillage. During systematically subsoil tillage and constantly shallow tillage these indices, compared with combined treatment, are somewhat higher. With an increase in fertilizers rates, weed infestation of soil significantly reduces. To improve the phytosanitary condition of crop rotation, constantly shallow tillage on the background of applying 12 tons of manure + N57R75K75 is recommended. | ||
