This study aimed to assess the economic efficiency of implementing photovoltaic (PV) systems in irrigated agriculture, taking into account the technical, financial and environmental aspects of their application. To achieve this objective, the energy efficiency levels of pumping stations, the cost of PV system installation, and mechanisms of government support were analysed. The findings showed that the introduction of solar energy in irrigation complexes reduced average electricity costs to U...

The aim of the study was to examine the potential of numerical modelling for improving agricultural machinery by analysing its characteristics and technological features. A theoretical analysis was carried out using theoretical modelling, which allowed for the evaluation of stress-strain states of the machinery under different loads. It was found that numerical modelling reduced the weight of machinery by removing excess material in low-stress zones and also decreased emissions through improv...

У дослідженнях, проведених у зоні Південного Степу України, встановлено позитивний вплив біодеструкторів стерні (Екостерн у різних формах) на підвищення вмісту сирого жиру в насінні соняшнику та його умовний збір з гектару. У контрольному варіанті (без біодеструктора, але з N5 і Граундфіксом) середній вміст жиру становив 44,1–44,3%. Застосування біодеструкторів підвищувало цей показник на 0,5–1,0 в. п., а додаткове проведення позакореневе підживлення препаратом Стоп стрес у фазу сприял...

A two-factor study was conducted to investigate the impact of inoculants on the productivity of soybean varieties from different maturity groups under the soil and climatic conditions of the steppe zone of Ukraine, following generally accepted methodologies. Factor A consisted of early-maturing (Krynytsia, Rizdvyana, Zlatoslava) and early-ripening (Aurelinа, Bettina, NS Maximus) soybean varieties. Factor B involved seed inoculation with bacterial preparations: control (water treatment), Biobo...

Pollution of agricultural soils with heavy metals caused by the activities of industrial enterprises, transport, and intensive use of agrochemicals poses a threat to environmental safety and productivity of agricultural systems. In this regard, the purpose of the study was to evaluate the effectiveness of combined use of green manure and organo-mineral stabilisers (zeolite and biochar) to reduce the bioavailability of heavy metals and phytotoxicity of the soil environment. The research method...
