We examined the effect of foliar fertilization on the yield of maize hybrids in 2013. The experiment was set in three repetitions, random blocks on an ecological farm. The soil of the experiment was chernozem. Soil analysis data showed that it had proper nitrogen, plenty phosphor and very good potassium content. During the experiment we applied two times foliar fertilization in 5-5 l/ha dosage. The year 2013 was unfavourable for maize production. In 2013 the amount of precipitation in the graining phase of maize was lower by 59 mm than the average. The yield of the control plots ranged between 9.9-11.8 t/ha, the yields of the foliar fertilization plots ranged between 10.3-11.47 t/ha. There were not significant differences between the average yields of control and foliar fertilization plots. By the application of foliar fertilization the yield fluctuation decreased. Factual conclusion can be drawn only after the results of several years, we wish to continue our examinations.
