Maize occupies about 46% of Romania's arable land, which is why it has been constantly in the attention of researchers who try to maximize production by various agrophytotechnical methods adapted to the climatic conditions so different in recent years. The aim of the research is to determine the influence of precipitation and temperatures on the growth stages of maize depending on the hybrid. To achieve the research objectives, a 3 x 3 x 3 three-factor experiment was established, sown in three repetitions according to the method of subdivided plots, with the following study factors: factor A - tillage system (a1-ploughing; a2-tiger; a3-disc), factor B - fertilization formula (b1-N0P0K0; b2-N90P40K40; b3- N90P40K40 + Greenstart (N4P10Mg0.5S1.25Zn0.5) and factor C - hybrid (c1-Mas 40 F; c2-Dartone; c3-P9911). The growth stages of maize are largely influenced by the climatic conditions of the study years. The influence of climatic conditions is also reflected in the level of production/yield. The amount of water in precipitation is used differently depending on the tillage, fertilization formula and hybrid used. Of the hybrids tested in the 3 years of experimentation, the P9911 hybrid is the most productive.
