In a one -- year pilot field experiment with maize were evaluated the yields -- qualitative parameters of KWS 9361 hybrid after the application of liquid N -- fertilizer DAM 390 applied either on its own as drip-out, respectively sprayed, or in combination with a cultivator as against hoeing itself and the control. The N dose was 156 kg N.ha-1 for all treatments plus supplementary fertilisation during vegetation in selected treatments to a total dose of 195 kg N.ha-1. During vegetation the samples were taken for analysis of plant N content and dry-matter yield, while the dry-matter weight of plants transienly decreased in treatment after foliar application of fertilizer, other treatments was no significant difference in the weight of plants. Grain yield was in the range 15.95 -- 16.59 t.ha-1, with no significant differences between the treatments. Thousand-seed weight, N content in dry-matter of biomass and starch content in the grain were not significantly affected by treatment. From an economic point of view can by recommended itself hoeing, which showed a gain of 1 556 Kč.ha-1. Conversely, the use of cultivator along a side dress treatment seems unprofitable (loss - 406 Kč.ha-1) on base of 1 -- year results.
