“…High-precision studies of the mechanical and technological properties of seed fruits are a key tool for achieving these goals and creating sustainable and productive crops (Serhiienko et al, 2023). The results of the studies of the static friction coefficients of melon and cucumber seeds made on different surfaces (perforated sieve, galvanised iron, aluminium plate) are presented in Table 3.…”

The introduction of organic technology for growing vegetable plants will help to reduce the environmental burden of pesticides and produce safe vegetable products with high yields. The purpose of the study was to investigate the effect of biological preparations on the organic cultivation of vegetable plants. Field, measuring and weighing, mathematical and statistical methods were used to determine the efficacy of the preparations. The study was conducted in 2018-2021 in different regions of Ukraine. It was established that the systemic use of biologics during the growing season of vegetable plants provided rapid growth and development, helped to increase immunity to diseases, reduced the activity of pathogenic microorganisms in the soil, and provided an increase in overall yield. The general use of biologic preparations in open ground conditions contributed to a total potato yield of 25.4 t/ha, and the complex use of preparations on Brussels sprouts forms a larger number of heads – 90 units. The Organic Balance biological product provided an increase in yield of up to 3.5 t/ha and 90% marketability of products when growing Chinese cabbage. Chemical analysis showed that the use of biologics increased the dry matter in tomato fruits by 1.03 % – in the Rio Fuego variety and 1.39% – in the Missouri variety. The yield increase in the studied varieties of asparagus beans Laura and Purpurova was 0.5 and 0.6 t/ha compared to the variants without seed inoculation. The use of biological preparations provided a higher yield in tomato plants of the Asvon variety by 2.2 t/ha, significantly reduced the content of nitrates in fruits to 50-80 mg/kg, while in the control – 110-170 mg/kg, increased the content of dry matter by 1.03 and 1.39%, depending on the variety. The gross yield of winter garlic with the use of biologics increased by 5%, and the marketability of potato tubers increased by 5%. Organic technologies would allow farmers to minimise the use of pesticides, produce environmentally friendly products, and increase yields

The analysis of literature sources shows that the production of seed material for vegetable and melon crops is one of the most important problems that exists in the field of agricultural processing. The production of cucumber and melon seeds is an urgent issue in view of the volume of their cultivation in Ukraine. To study the processes of fruit grinding and seed production in agriculture, the key parameters are the dynamic friction coefficient, the volume deformation coefficient and the static load coefficient, but existing methods and equipment are limited to determining the limit values of the indicators, not allowing a full study of the dynamics of changes in properties at different stages of the technological process. To solve this, it is proposed to develop new methods, in particular, the use of computer modelling, which will allow a more detailed study and optimisation of physical and mechanical properties and their changes. The aim of the article was to study the physical and mechanical properties of vegetable fruits, which have the greatest impact on the quality of the technological process of fruit seed grinding and preliminary seed extraction. The study was conducted in the problematic research laboratory of the Faculty of Engineering and Energy of Mykolaiv National Agrarian University. Experimental setups were used to determine the dynamic coefficient of friction of melon and cucumber seeds, a device for determining the initial density of seed fruits, and a device for determining the dependence of seed deformation on compressive load. Experimental data show that the most optimal values of the static coefficient of friction, depending on the type of surface, for cucumber and melon seeds are perforated sieves, the values of which are 0.75 and 0.85, respectively. Optimal values of dynamic friction coefficients for cucumber have a surface made of perforated sieve – 0.69 and for melon made of aluminium – 0.88. The dependence of the linear deformation of seed fruits on the specific pressure increases from 0.9 to 3.6. The values of fruit deformation from compressive load vary from 4.1 to 24.6. The research presented in the article is of practical importance and can be used in the field of agricultural production and in the development of new engineering solutions
