Abstract: The pur­pose of this work is to eval­u­ate the corn pro­duc­tion obtained fol­low­ing the change of the sow­ing date. In the cur­rent con­text of cur­rent cli­mate changes, adap­ta­tion of cul­ti­va­tion tech­nol­o­gy is essen­tial to obtain sat­is­fac­to­ry quan­ti­ta­tive and qual­i­ta­tive results. The exper­i­men­tal fac­tors ana­lyzed in this study are sow­ing sea­son with three gra­da­tions (Sea­son I — 6ºC in soil; Sea­son II — 8ºC in soil; Sea­son III — 10ºC in soil); corn hybrids (Tur­da 248 – con­trol; Tur­da 165; Tur­da 201; Tur­da Star; Tur­da 332; Tur­da 344; Tur­da 335) and the cli­mat­ic con­di­tions of the two exper­i­men­tal years (2020; 2021). In 2021, pro­duc­tion was low­er than in 2020, with 922 kg/ha, the cli­mat­ic con­di­tions dur­ing the veg­e­ta­tion peri­od being the deci­sive fac­tor in the real­iza­tion of these pro­duc­tions. All ana­lyzed hybrids record­ed a high­er aver­age yield when sown at  8ºC (10504 kg/ha), com­pared to the oth­er two sow­ing sea­sons. Among the ana­lyzed hybrids, the Tur­da 335 hybrid achieved the high­est pro­duc­tion (10862 kg/ha), 48 kg/ha more than the Tur­da 248 con­trol.
Key words: sow­ing sea­son, corn, yield, cli­mat­ic con­di­tions
