Microorganisms number in sorghum (Sorghum bicolor (L.) Moench) rhizosphere after herbicide, plant growth regulator, and a biopreparation use

In the modern agricultural production, the use of herbicides and other biologically active substances is an important part of the cultivation technologies of most cereals, including the grain sorghum. It is known that most preparations, including the chemical ones, can directly or indirectly influence the development of microorganisms in the rhizosphere of plants, but the nature of their effect on the microbiota of grain sorghum rhizosphere has not been studied enough, which reasoned the relevance of this research. Microbiological activity of the grain sorghum rhizosphere (hybrid Milo W) was studied during 2019–2020 under the treatment by the herbicide Citadel 25 OD (0.6; 0.8 and 1.0 l/ha), plant growth regulator Endophit L1 (30 ml/ha) and biological preparation Bioarsenal (800 g/ 100 kg). The analysis of the obtained experimental data showed that use of the studied preparations both separately and in different compositions had a stimulating effect on the number of grain sorghum rhizosphere microbiota, which was observed in its increase, especially in variants with the combined use of the herbicide Citadel 25 OD, plant growth regulator Endophit L1 and the biopreparation Bioarsenal (compared to the control the number of rhizosphere microbiota increased by 29.4–80.6% in average by groups).

Sorghum Bicolor L

Content of the chlorophylls and carotenoids in a pigment complex is one of the most important factors that determine the productivity of crops of cereals. Although it is well known that herbicides and plant growth regulators may cause changes in the amount of pigments, there is lack of researches about their separate and integrated influence on the pigment complex of grain sorghum (Sorghum bicolor (L.) Moench). Therefore, we aimed our research to investigate the response of grain sorghum’s pigment complex to the impact of the herbicide in different combinations with the plant growth regulator and biopreparation. In result, it was found that the content of the pigments was decreasing simultaneously with increasement of the herbicide rate. However, the obtained data indicates that the complex usage of the herbicide and plant growth regulator had an auspicious influence on the pigments content, compared to the variants where only herbicide was applied. The similar auspicious effect appeared, when the herbicide was applied on the background of pre-sowing seeds treatment by the biopreparation Bioarsenal. It is noticeable that in this case the increasement of pigments content was higher than in the variants of compatible application of the herbicide and plant growth regulator. The highest indicators of the pigments content formed when the herbicide was applied compatible with the plant growth regulator on the background of pre-sowing seeds treatment. The content excess of the chlorophylls a, b, a+b and carotenoids, relatively to the control, amounted 7,4 – 9,1%, 16,0 – 18,3%, 9,4 – 11,2% and 35,5 – 40,2% respectively. It is evident that usage of the herbicide Citadel 25 OD compatibly with the plant growth regulator Endofit L1 on the background of pre-sowing seeds treatment by the biopreparation Bioarsenal is an effective measure, which allows to reduce the harmful impact of the xenobiotic on the pigment complex of grain sorghum

Physiologically Active Substances

Herbicides, being substances with a high physiological activity, can affect not only weeds but also cultural plants. At the same time, there are many evidences that usage of plant growth regulators and pre-sowing seeds treatment by biological preparations can reduce the potential harmful impact of herbicides. Antioxidant systems are one of the first plant systems which react to the permeation of exogenous physiologically active substances. Therefore, one of the effective ways to estimate the influence of different preparations on plants condition is estimation of the antioxidant enzymes activity, particularly — catalase, peroxidase and polyphenoloxidase. To estimate enzymes activity in leaves of grain sorghum, a field experiment has been laid. It was conducted in crop rotation of the biology department of Uman national university of horticulture during 2019–2020. In the experiments were used: grain sorghum (Sorghum bicolor (L.) Moench) of the Milo W hybrid, herbicide Cytadel 25 OD in rates of 0,6; 0,8 and 1,0 l/ha, plant growth regulator Endofit L1 (30 ml/ha) and biopreparation Bioarsenal (800 g/100 kg). Enzymes activity was estimated in phases of tillering and throwing panicles. It was established that the enzymes activity of grain sorghum depended on the herbicide rate and raised simultaneously with its increasement. However, application of the herbicide in conjunction with the plant growth regulator Endofit L1 caused more significant increasement of the investigated enzymes compared to the variants where only herbicide was applied. The similar effect established in variants where the herbicide was applied on the background of pre-sowing seeds treatment by the biopreparation Bioarsenal. The highest activity of the antioxidant enzymes established in the variants where the herbicide Citadel 25 OD in rates of 0,6; 0,8 and 1,0 l/ha was applied in conjunction with the plant growth regulator Endofit L1 on the background of pre-sowing seeds treatment by the biopreparation Bioarsenal. It indicates increasement of the plant’s antioxidant status in case of using this combination of preparates.

The article deals with the study of the effect of the application of the herbicide Granstar Gold 75, w.g. (water-soluble granulate) and plant growth regulator Regoplant on some ecological indicators of ecocenosis of winter wheat sowing (lipid peroxidation reactions in winter wheat plants by the activity of malonic dialdehyde content accumulation, enzymatic activity, total number of rhizosphere bacteria and anatomical structure of winter wheat leaves). The choice of research topic is due to the fact that currently obtaining high yields of winter wheat is closely connected to the widespread use of chemicals, in particular, herbicides, which by their nature are physiologically active substances that can affect both plants and soil microbiota. This, in turn, leads to the search for environmentally safe elements of technologies for growing winter wheat. One such element may be the use of herbicides together with plant growth regulators. The obtained experimental data testify to the protective ability of the growth regulator Regoplant against the winter wheat plants, as evidenced by a decrease in the activity of malonic dialdehyde accumulation, changes in the activity of the enzymatic defense system, decrease the number of epidermis cells and an increase in total rhizosphere bacteria in case of Regoplant use together with Granstar Gold 75, w.g. compared with the experiment variants, where the herbicide was applied without a growth regulator. That is, the use of growth regulator in a mixture with herbicide to some extent eliminates the toxic effect of xenobiotics, which has a positive effect on the state of ecobiosis of winter wheat sowing.
