| description | Corn is one of the main crops of modern world agriculture, versatile use and high yield, which can largely solve the problems of food security. Various types of weeds can cause significant losses of its yield, which can reach 50% or more, which makes it necessary to provide for protective measures against them in technological schemes of corn cultivation. In corn cultivation technologies, the weed control system is of great importance, since corn grows very slowly at the beginning of the growing season. The purpose of the research is to study the influence of various agrotechnical techniques on the number and variety of weeds in sugar corn crops in the conditions of the Lower Volga region. The tasks of the research are to determine the number and species composition of weeds during the growing season of sweet corn; to determine the effect of herbicides on weeds in sugar corn crops. The experiments were carried out in LLC “Kuznetsovskaya” agricultural company of the Ilovlinsky district of the Volgograd region and in S.A. Popov’s farm of the Chernoyarsky district of the Astrakhan region. The research period is 2009...2015. The contamination was determined by quantitative and weight method on an area of 1 m2. According to all variants of the experiment, the contamination was attributed to a mixed juvenile and long-term type, while no stable patterns were observed in changing the ratios between these components.As a result, it has been revealed that the number of weeds in LLC “Kuznetsovskaya” of the Ilovlinsky district of the Volgograd region varied from 6 to 17 pcs./m2. For dump tillage, this indicator varied from 6 to 11 pcs./m2, for zero tillage – 13...17 pcs./m2. In S.A. Popov’s farm of the Chernoyarsky district of the Astrakhan region, the number of weeds for dump tillage was 4...9 pcs./m2, depending on the influence of agrotechnical reception, for zero tillage contained from 10 to 17 pcs./ m2. |
