This paper deals with a study on the fertilisation influence with nitrogen in time with maize sowing on theuniformity of rising and growth strength at main hybrids cultivated in Transilvania, from seeds of diverse calibres. Theaim of this study has started from the fact that the solubility of ammonium nitrogen near maize seeds is done throughheat absorption and this fact could influence the germination processes and the manifestation of their strength.The experimental results obtained show us that the application of nitrogen on the sowing line can havecontradictory effects. At seeds of larger dimensions (LL and LR) it induces a reduction of the rising rythm and of itsgrowth strength, and at seeds of smaller dimensions (ML and MR) it stimulates rising and growth strength of plants.
