Inoculation, as a technological operation, is currently underestimated, yet it has repeatedly proven its effectiveness. Its application in production or scientific research typically leads to improvements in yield, grain quality, or plant biometric parameters under study. However, the inoculation process itself is not standardized by any legislative act, so farmers rely solely on recommendations from manufacturers of inoculants and carry out this operation using, so to say, makeshift means. Therefore, a system of at-planting inoculation has been developed, which involves conducting this operation directly in the field. Hence, the aim of this study was to investigate the parameters of pressure and nozzle diameter that would provide the optimal amount of inoculant on the seeds and would be as close as possible to the manufacturer's recommendations. To conduct the study, a system model was created in which nozzles with diameters of 0.2, 0.3, 0.4 and 0.5 mm were investigated under pressures of 3, 4, 5 and 6 atm. The optimal amount of working solution per 1 ton of seeds was calculated for conducting the operation in the usual way, and the amount of liquid reaching 1,000 maize seeds was determined. Thus, the optimal pressure and nozzle diameter were identified. With a pressure of 3 atm in the system, none of the nozzles provide the required amount of working fluid. A similar situation occurs with a nozzle diameter of 0.2 mm. However, at higher pressure in the system and with other nozzle diameters, it is still possible to provide the necessary amount of liquid. Therefore, for the at-planting inoculation system, it is advisable to use a pressure of 4 atm and a nozzle diameter of 0.4 mm.
