Maksymov D. The productivity and quality of haricot beans depending on soil tillage, mineral fertilizers and row width under irrigation

The object of research is the processes of changing the physicochemical properties of the soil, growth, development, formation of plant productivity, harvest and quality of beans grain, depending on the depth of plowing, the dose of mineral fertilizers and the width of the spacing. The purpose of the research is to develop technological methods for growing common beans in irrigated conditions in the Southern Steppe of Ukraine, which will ensure the preservation and improvement of soil conditions, will give an opportunity to obtain a highly liquid grain harvest. Methods of research - historical; field short-term multifactorial experiment; laboratory; calculated; statistical; programming. Research results - For the theory: For the first time the features of growth, development and formation of harvested beans harvested in the conditions of the Southern Steppe of Ukraine when irrigated by waters of the 2nd grade of quality were studied. Mathematical models of modeling the development of the resulting factor (yield level) are created, depending on the change of the investigated element of the technology of cultivating culture. For practice: Application in the production of the recommended agro-technical complex of common bean cultivation will allow agricultural commodity producers to increase the productivity of crop rotation units, by increasing crop areas under cultivation, partially solving the problem of protein deficiency, by increasing the gross harvest of grain; improve land reclamation and increase their fertility. Sphere of use - agricultural enterprises of the south of Ukraine.
