The review analyzes the effect of organic-mineral fertilizers (OMF) on morphogenesis, physiological processes, productivity and fruit quality of edible tomato (Lycopersicon esculentum Mill.). Tomatoes are known to play a primary role in providing the population with quality vegetable products, due to a large number of sugars (2.5–4.2 %), organic acids (0.4–0.9 %), vitamins, lycopene (0.3 %), fiber (0.3–0.9 %), mineral and aromatic compounds. The annual rate of human consumption of tomatoes, according to scientists, should be 39 kg. It is noted that the use of OMF and humic preparations is an integral part of organic farming. According to DSTU ISO 4884: 2007 organic-mineral fertilizer is a fertilizer obtained by physical and / or chemical interaction of organic and mineral components. Growing tomatoes using organic technology reduces the size of the fruit, but makes tomatoes more tasteful compared to fruits grown in the traditional way, the accumulation in the fruit of useful iron, magnesium, vitamins and minerals. It is shown that humic compounds have a positive effect on all phases of the mitotic cycle of cells and increase the value of the mitotic index by 1.5 times, resulting in increased root formation, changes of cell membranes increase water supply and nutrients. Treatment of seeds before sowing with liquid complex nitrohumine fertilizer containing macro- and microelements increases germination by 10%. Feeding tomato plants with liquid OMF during the growing season allows to intensify the process of photosynthesis, ensure better development of the leaf surface and root system, increase the laying of more reproductive organs and reduce disease incidence, resulting in a 40 % increase in yield and improved quality. The stimulating effect of humic acids on rooting of tomato seedlings, growth processes, increase of resistance to temperature decrease is revealed. Growth stimulants and liquid nitrogen fertilizers also streamline growth, increase productivity and quality of tomatoes. Thus, the use of organic-mineral fertilizers based on humic substances affects the development of edible tomatoes, streamlines the physiological processes in plants, their resistance to abiotic and biotic factors, fruit yield by 26–51 % and their quality, morpho-biometric and biochemical parameters of seedlings.

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.
