Abstract
The main criteria for the functioning of agronomic phytocoenosis are indicators of their economic and energy efficiency. In particular, the issues of manufacturability and rational use of sown areas during the growing season characterize the level of agronomic culture in a particular geographical area. Under these conditions, it is important to study the possibility of joint cultivation of agricultural plants, which will reduce energy consumption, improve the phytosanitary condition of crops and increase the profitability of agricultural production. When growing tomatoes in compatible crops, it is necessary to take into account not only aspects of technology, but also the interaction of plants with each other at the level of physiological and biochemical processes. That is why allelopathic relationship between plants, due to the physiologically active substances they secrete at the initial stage of ontogenesis, is not without the interest. It is the scientific basis for the development of sound crop rotation and mixed (compacted) crops, and also helps to increase the productivity of agro- and natural coenoses in order to prevent soil fatigue in monoculture, control weeds, pests, phytopathogenic organisms, etc. Allelopathic substances (collins) of some plant species cause different reactions to other species: some of them have active growth, others have suppressed growth processes, and still others remain neutral to such effects. The stimulating effect is manifested in the awakening of seeds, strengthening of growth processes and the formation of seedling organs. In future this fact will lead to the activation of plant development and an increase in their productivity. At the same time, mutual oppression of plants cannot be ruled out, which can be detected during laboratory studies using biological tests. Field studies of compatible (compacted) crops of tomato with other plants (sugar corn, shallots) were performed using allelopathic testing methods according to Grodzinsky. The expediency and economic efficiency of growing tomatoes in compatible crops with shallots on a green feather have been experimentally proved using statistical methods.
Highlights
These studies are aimed at developing of the elements of the tomato cultivation technology in the conditions of compaction of its crops by other crops
Tomato compactors: shallots on a green feather were planted in the aisles of a tomato immediately after planting it to a depth of 4 - 5 cm according to the scheme 140x8 - 10 cm (80 - 85 thousand pieces per hectare), sugar corn was sown in the aisles of tomatoes with a density of 14 thousand pieces per hectare
The influence of the donor plant on the acceptor plant through allelopathic interactions differs in the direction of the action and in the degree of its manifestation
Summary
These studies are aimed at developing of the elements of the tomato cultivation technology in the conditions of compaction of its crops by other crops. The biological feature of tomato is that it can form high yields with minimal feeding areas without reducing the quality of products The chemical interaction of plants is focused on the mechanisms of the physiological action of allelopathically active substances (collins). It is a mixture of physiologically active compounds secreted by plants or formed in their immediate environment as a result of the activity of heterotrophic organisms or physicochemical factors that effect on the surrounding plants positively or negatively The interaction of plants is mainly carried out through the soil, since 60 - 90% of collins (root secretions) per unit the area is concentrated in the soil It is especially important to calculate the vegetation cover in compacted crops correctly (as the beginning and basis of the functioning of the biological circulation of substances and energy) in modern vegetable growing
