“…Under these weather conditions, the formation of potato seed material is possible with a second-crop culture. Similar technology, as evidenced by L. Boiarkina et al (2020), is used in the south of Ukraine and avoids the negative impact of adverse conditions on the formation of potato seed tubers. Therewith, the first crop is harvested before the period of maximum air temperatures, and the second crop is formed at favourable temperatures in September-October.…”

The relevance of the conducted studies lies in the need to improve the technology of growing potatoes from freshly picked tubers in the conditions of summer planting to improve the quality of seed material. The purpose of the study was to determine the influence of the physiological and biochemical state and varietal characteristics of potato plants on the ability of freshly harvested tubers to form high-quality seed material for second-crop potatoes in the Forest-Steppe of Ukraine. Field, statistical, computational, analytical, and laboratory methods were used to conduct the study. It is identified that harvesting the first crop for planting with freshly picked tubers during the flowering phase and within two weeks after its completion is ineffective for some varieties. Therewith, the first crop averages 18.5 t/ha, and the second – 5.1 t/ha. Some varieties have a low germination rate from freshly picked tubers (from 4 to 76%) or are not formed at all. This is due to the accumulation of germination inhibitors (abscisic acid etc.) in maturing tubers, which causes deep natural dormancy of tubers. It is proposed to consider the activity of germination inhibitors in freshly harvested tubers using allelopathic testing, which allows for determining the optimal time for their collection and planting. This ensures germination rate at the level of 80-87%. Therewith, the first crop of tubers is from 10.1 to 15.0 t/ha, and the second – from 26.2 to 9.3 t/ha. The dependence of the content of abscisic acid with the accumulation of starch in tubers allows visually determining their suitability for germination by the chemical reaction of vegetable juice with an iodine solution. The practical value of the study lies in the possibility of obtaining two crops of seed potatoes per year, while the first crop is formed in 60-70 days, and the second – 90-100 days from planting. Despite the relatively low yield, the resulting seed material is physiologically young, free from diseases and has a high productivity potential. This allows for shortening the seed production scheme, increasing the reproduction rate of potatoes, and saving resources

In the present-day world, the demand for organic products is growing, but there is an insufficient number of studies on the impact of biological preparations on soil fertility parameters. Indicators of microbiological activity are not the same for different soil types, which is why it is necessary to investigate them in detail in specific soil and climatic conditions, especially on zonal soils, which are sod-podzolic soils in Polissia. Research on the impact of various biological preparations on soil fertility indicators for the cultivation of one of the most popular crops in Ukraine – food potatoes – is relevant. The purpose of this study was to establish the effect of treatment of potato tuber seeds with biological preparations and introduction of a biodestructor for better decomposition of siderate on the focus of microbiological processes in the soil. The study was carried out in an experiment at the Volyn State Agricultural Research Station of the Institute of Potato Growing of the National Academy of Agrarian Sciences of Ukraine. The soil of the experimental site was sod-medium-podzolic sandy soil on water-glacial deposits. The stationary experiment included variants with the addition of siderate to the soil without a destructor (Background 1) and with the addition of the Ecostern destructor to the siderate (Background 2). The effectiveness of the following biological preparations was also investigated: Mycohelp, Agat, Regoplant, Fitohelp, Stimpo. Soil analysis for microbiological indicators was carried out in samples taken from the 0-20 cm layer. The focus of microbiological processes in the soil was found by the corresponding coefficients. It was found that the oligotrophicity coefficient was less than one on the variants using the Ecostern biodestructor during the growing season of potatoes, which indicates a good supply of easily digestible organic substances to the soil microbiota, while on the variants without Ecostern during the ripening phase, the oligotrophicity coefficients exceeded one. The coefficient of pedotrophicity changed more during the growing season than according to the variants of the experiment. In the seedling and flowering phase of potatoes, mineralisationimmobilisation coefficients were low in all variants of the experiment, which indicates the predominance of synthesis of organic matter. The materials of this paper are of practical value for farmers and producers of organic crop production in the issue of plant residue management for the use of biodestructors in the technology of growing food potatoes
