Ensuring uniform transverse distribution of spray liquid during crop protection treatments is a key factor determining the effectiveness of pesticide application and reducing losses of active ingredients. Non-uniform application leads to untreated zones and local overdosing, which negatively affects both crop yield and environmental safety. This article presents the results of experimental research on the influence of boom height and operating pressure in the supply line on the uniformity of spray distribution when using flat-fan nozzles.
The experiments were conducted on a test bench manufactured in accordance with relevant standards (ISO) for evaluating distribution uniformity. Boom height was varied within the range of 0,15-0,9 m, while the operating pressure was adjusted between 0,2 and 0,6 MPa. The collected data were processed using the least squares method, with determination of mean values, variances, standard deviations, and coefficients of variation. Regression models were developed in the Wolfram Mathematica environment, and corresponding response surface plots were generated to identify optimal operating zones for the sprayer.
The experimental results showed that at boom heights below 0,4 m, the coefficient of variation reached 30-75%, exceeding agronomic requirements several times. Increasing the height to approximately 0,6 m significantly reduced distribution non-uniformity for all pressure levels studied. Using the constructed response surfaces, optimal combinations of parameters that provide the highest level of spray uniformity were identified.
Practical recommendations were formulated for field application: a boom height of 0,7-0,8 m is advisable at 0,2 MPa; 0,5-0,7 m at 0,3 MPa; and approximately 0,5 m at 0,6 MPa. The findings can be used to improve spraying guidelines and enhance the efficiency of pesticide application. The article also outlines prospects for future research aimed at further optimization of structural and operational parameters of boom sprayers.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016).
