Abstract
Humanity at the present stage of development has already faced the consequences of its economic activities, which has caused global changes in the world around it. Climate change on our planet is observed in all regions. As is known, this period is geologically anthropogenic, which is characterized by alternating glaciations. The main development and implementation of the country's food security program is the creation of a sustainable food supply. And also, the growth of livestock production in line with population growth. Corn is widely distributed in the world due to its high productivity and nutritional value, as well as its ability to adapt to different climatic zones. Corn is a crop sensitive to cold, and it has a serious delay in growth and development when exposed to sudden cold spells in the early period of growth and development. For the successful promotion of this crop to more northern regions, it is necessary to include hybrids with low thermal requirements in agricultural production. It is also equally important to create favorable conditions for plants in new regions. The purpose of the research was to build a dynamic model of corn cultivation at low temperatures due to climate change at the global level. The main area of research was to identify the possibility of normal functioning of corn in conditions of low temperatures. The first experiment (2004-2007) was aimed at a comparative study of various subspecies and varieties of corn to identify morphobiological factors of adaptation process management. In the second experiment (2012-2013), the subject of the study was the effect of various drugs, including derivatives of indolylacetic acid, and the timing of crop sowing on its productivity. Thus, the morphobiological, agrotechnical and microbiological issues of increasing the cold resistance of corn as the main food and feed crop have been studied. The influence of the studied factors on the growth processes and yield of green mass has been determined.
