W pracy określono wpływ dawki cieczy użytkowej na hektar, na jakość opryskiwania pszenicy ozimej. Jakość opryskiwania pszenicy ozimej określono za pomocą wskaźnika rozkładu masy na 1 cm² liścia rośliny (mk).
Quality of winter wheat spraying with 3% solution of urea with admixture of Fluoresceine was determined. The quality of spraying was evaluated using an index of liquid mass distribution per 1 cm of plant leaf area (m ). The spraying was performed with a tractor sprayer, implemented with spray nozzles of TeeJet XR 11003 type. The studies showed that the application of usable liquid in doses higher than 200 1/ha is unreasonable. It was also stated that the increase in spraying velocity did not affect significantly the distribution of liquid at the three distinguished levels in wheat canopy.
