The study of the nitrogen fertilizing influence during maize seeding on the sprouting and growing vigor uniformity in the main hybrids cultivated in Transylvania, using different calibers seeds, is presented in this paper. This study was performed starting from the assumption that ammonium nitrate dissolution near maize seeds is an endothermic process and this could influence the germination processes and manifestation of their vigor. Experimental results obtained shows that nitrogen application on the sowing line may have contradictory effects. Nitrogen large seed induced a reduction in the rate of sprout vigor and growth, and seed size smaller growing stimulates growth and vigor of plants.
