Abstract
The article provides the analysis of the research results of the effect of pre-sowing seeds inoculation with the microbial preparations Microhumin and Phosphoenterin along and in combination with the crops treatment with the plant growth regulator Biolan on the different backgrounds of mineral nutrition on the productivity and quality of spring barley of Sozonivskiy variety in the conditions of the Northern Steppe of Ukraine. The application of biological preparation on the natural background (without fertilizers) is economically justified.
Highlights
An important argument in favour of biological preparations use is that they have relatively low cost, but their effectiveness is largely dependent on weather conditions and of farming culture [5]
Traditional technological factors include the use of high doses of mineral fertilizers, crop protection chemicals from diseases, pests and segetal plants
The elements of new technologies are developed that involve the use of microbial preparations
Summary
An important argument in favour of biological preparations use is that they have relatively low cost, but their effectiveness is largely dependent on weather conditions and of farming culture [5]. Increased production of high-quality grain of spring grain crops and its sustainable use is one of the main tasks of modern agriculture of Ukraine. Traditional technological factors include the use of high doses of mineral fertilizers, crop protection chemicals from diseases, pests and segetal plants. A special factor that can influence the efficiency manifestation of microbial preparations is the level of mineral fertilizers application.
