The demand for sweet corn is increasing from year to year both worldwide and in our country. On the other hand, this crop can represent a source of income for farmers who own small areas of land. In addition, thanks to the relatively short period of vegetation, it can be cultivated in areas where the de-springing occurs earlier, so that the crop can benefit from the moisture accumulated in the soil from the cold season and the precipitations from the spring, avoiding periods of atmospheric drought and in the soil, increasingly common in recent years starting in July and August. The research focused on the behavior of an assortment of 11 sweet corn hybrids sold on the market in our country, from different precocity groups, in terms of cob insertion height and cob length, in the pedoclimatic conditions of the Ramna area, Caraș Severin county. The area where the research was carried out is characterized by an early spring, the minimum germination temperature of 10 0C, occurring in the first days of April. With reference to the cob insertion height, hybrid 2- Spirit F1 and hybrid 5- Starshine F1- class I, with cob insertion at a height of approximately 50 cm, are inferior to the other hybrids taken in the studio, and hybrid 9-Driver F1, with the insertion value of the 60 cm cob - class A, is clearly superior to all the hybrids studied. The highest cob length value – about 24 cm, was obtained at a10 [Accentuate F1 ] and a9 [Driver F1] – class A, which differs significantly from other hybrids. The lowest value of about 18 cm was obtained at a8 [Landmark F1] and a4 [Tyson F1] – class E, a value that differs significantly from the other hybrids.
