Protection of corn from weeds under the conditions of the Lugansk region
Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 104, Issue
Abstract
The steady demand for corn grain, as well as its agro-technological benefits contributes to a significant increase in the area of this crop both on a global scale and in Ukraine. The main task of care for corn crops is to create optimum conditions for germination of seeds and to obtain dense standing crops, protect them from weeds, diseases and pests, and provide moisture and nutrients at all stages of organogenesis. During the cultivation of corn, the grower faces an acute problem – weeds. Weeds can cause losses of 20–70% of the grain yield. It is known that corn belongs to weak weed competitors in agrophytocenoses. Especially critical is the period of early phases of development of the crop, therefore, it is necessary to protect corn during this period. The experiments were conducted with the aim of developing and studying the optimal parameters of the main elements of technology with the use of non-volatile herbicides – the effectiveness, time and methods of their application. The practical value of the results of research and their bioenergy and economic evaluation allowed us to develop recommendations taking into account the influence of herbicides of different spectrum of action, terms of their introduction, methods, tools and depth of application. The developed recommendations have a great practical importance. Their implementation on a large scale will contribute to the conservation and restoration of soil fertility, the maintenance of environmental equilibrium in agrocenosis and improvement of corn yields. Nowadays, there is a wide range of drugs to reduce the weediness of corn crops. The effectiveness of soil herbicides Trophy (2.5 l/ha) and Oscars (4.0 l/ha) were studied in the conducted experiment
