The study presents the results of sweet corn production4 autochthonous hybrids (Estival, Dulcin, Prima and Deliciul Verii), depending on their interaction with the level of mineral fertilization and the specific climatic conditions of the researched area.The research was carried out on the territory of Ramna commune, located in the north-west part of Caraș Severin county,on a eutric-gleic alluvial type soil, moderately glaciated, extremely deep, medium loam/coarse sandy loam, developed on medium (clay) non-carbonate fluvial deposits.The obtained results show that the production of sweet corn has an upward trend from the Estival hybrid to the Dulcin hybrid, a downward trend from the Dulcin hybrid to the Prima hybrid and an upward trend again from the Prima hybrid to the Deliciul Verii hybrid. The production values of sweet corn varied between 14340 kg/ha and 15740 kg/ha. The lowest production of sweet corn was obtained at a1[Estival], and the highest at a2[Dulcin]. The differences between the hybrids are highly significant [p<0.001]. Depending on fertilization, the production of sweet corn has an upward trend depending on the level of fertilization. The values vary between 14074 kg/ha and 16290 kg/ha. The differences between fertilization levels are highly significant [p<0.001]. Sweet corn production increases with the level of fertilization. The highest production values are obtained on the N160P90K90 agrofund, and the lowest on the N120P90K90 agrofund, regardless of the tested hybrid. If we compare the hybrids, we can see that the highest production is obtained in hybrid 2[Dulcin], and the lowest production in hybrid 1[Estival], regardless of the level of fertilization.
