Microbiota count of Sorghum orysoidum rhizosphere under the use of herbicide and plant growth regulators
Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 102, Issue
Abstract
The article presents the results of research on the change of the total count of microbiota, micromycetes and azotobacter in rhizosphere of Sorghum orysoidum crops depending on the rates of herbicide Peak 75 WG (10; 15; 20; 25 g/ha) application and methods of applying plant growth regulator Regoplant (crop spraying (50ml/ha) and seed treatment (250 ml/t)). In the course of research, there was found a dependence of the development of soil microbiota in Sorghum orysoidum crops on various herbicide rates and methods of application of the plant growth regulator. It was determined that the optimal effect on the soil microbiota was achieved in the variants of complex application of the herbicide with plant growth regulator: Regoplant 250 ml/t (seed treatment) + Peak 75 WG 15-20 g/ha + Regoplant 50 ml/ha (treatment of vegetative plants).
