Korobko O. Biological substantiation of herbicide`s application, plant growth regulator and microbial preparation in chickpea crops in the conditions of the Right Bank Forest Steppe of Ukraine

The dissertation is devoted to the biological substantiation of Panda herbicide`s action against the background of differentiated and combined application of the plant growth regulator Stimpo and the microbial preparation Rizobofit on physiological and biochemical, productional changes in chickpea plants and microbiological in the soil for the purpose of development and chickpea plant growth technology of biologizm elements. The possibility of complex application of Panda herbicide with plant growth regulator Stimpo and microbial preparation Rizobofit is generally determined and substantiated in the research work. It`s significantly activated the passage of key biological processes in plants and soil, which in general causes an increase in productivity of chickpea crops at the same time as growing production of economical growth and energy efficiency of cultivating the crop. In particular, it was investigated that with the complex use of herbicide (Panda 3,0–6,0 l/ha) with the plant growth regulator Stimpo (0,025 l/t) and the microbial preparation Rizobofit (1,0 l/t) in chickpea crops in comparison with variants of self-use of the herbicide, a rather perceivable activation of growth processes was observed, which was manifested in the formation of a larger area of the leaf apparatus, height and above-ground biomass of plants, in particular, under the action of Panda 4,0 l/ha in combination with biological preparations, the above-mentioned indicators on the average grow to 20–88%.
