NIKITENKO M. Development of adaptive technology of millet cultivation in the south of Ukraine

The scientific novelty of the results obtained was to increase the productivity of millet variety Denvikske by applying organic fertilisers with pre-sowing seed treatment and subsequent foliar feeding of plants during the growing season. The variation of millet sowing was achieved by changing the row spacing, which provides a more complete characteristic of the assimilation of the necessary nutrients and the competitiveness of cultivated plants in a more favourable position. The practical significance of the research results is directly related to the scientific work in the development and implementation of adaptive technologies for millet cultivation, which allows to prevent the reduction and shortage of crop yields under the negative impacts and manifestations of natural and climatic changes in southern Ukraine. The purpose and objectives of the study were to scientifically substantiate the direct impact of biological fertilisers and multifunctional complex preparations on the productivity of crop plants and to search for the synergistic effect of these factors in the case of their combination in the process of caring for millet crops. Object of research - growth and development processes of millet of the Denvikske variety under different doses and types of biological fertilisers in non-irrigated conditions in the south of Ukraine. The subject of the study is a set of scientific provisions and applied elements of adaptive technology for growing millet of the Denvikske variety. Methods: field, laboratory, calculation, statistical. The main provisions of the dissertation research during 2021-2023, implemented, in the FG ‘RUBICON-AGRO 2003’, Mykolaiv region, Bashtanka district, Novyi Buh town on an area of 1.9 ha; FG ‘DEMETRA-K’, Mykolaiv region, Vitov district, Prybuzke village on an area of 10 ha; FG ‘USPIKH’, Mykolaiv region, Bashtanka district, Promin village - 5 hectares; PE ‘PSP “ZORYA”, Mykolaiv region, Bashtanka district, Tamaryne village - 205 hectares; PE “AGROFIRMA ”AVANGARD’, Odesa region, Bilhorod, Dniester district, Sadove village - 57 hectares. In total, the area of implementation of the research results was 278.9 hectares.
