Abstract
The article presents the results of a study on the productivity and economic efficiency of cultivating maize hybrids depending on irrigation methods and different schemes of plant protection against diseases. Irrigation is one of the most important elements of the technology of growing corn hybrids. Therefore, the importance of studying the influence of different methods of watering on different schemes of plant protection from pathogens of diseases that have the greatest economic value is relevant. The purpose of the research was to study the productivity and economic efficiency of growing maize hybrids for different irrigation methods and schemes of plant protection against pathogens. Also the objective of research was to determine the influence of the investigated factors on phonological indicators, yield dynamics and economic efficiency of corn cultivation on grain. Field experiments were conducted in accordance with experimental procedures, testing and application of pesticides. Agrotechnical cultivation of maize hybrids for grain was generally recognized for the conditions of southern Ukraine, in addition to the investigated methods of irrigation and schemes of protection of plants against pathogens. During cultivating maize for grain, the maximum yield of grain at the level of 14.5 t/ha provides the use of the hybrid N.K. Pako, with drop irrigation and the maximum chemical protection against pathogens. The developed technology of corn cultivation provides conditional net profit of 36.3 thousand UAH/ha and profitability at the level of 157%. Considering the relevance of the research direction, it is planned to study the effectiveness of the use of biological means of plant protection in the cultivation of corn for grain in different ways of watering.
