The culture of sweet corn in recent years shows a growing interest among farmers in Romania, especially those with smaller areas of land, but also those with large areas, due to the increase in consumer demand, the profitability of this type of crop and the the possibility of attracting financing sources from European funds.The purpose of this study is to analyze the impact of mineral fertilization on the production of sweet corn in an assortment of marketed hybrids, in the pedoclimatic conditions of 2020.The biological material used in the study of the influence of mineral fertilization in relation to the pedoclimatic conditions in the researched area and the average of the field, was represented by 4 autochthonous sweet corn hybrids(Estival, Dulcin, Prima and Summer Delight). 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. Analyzing the production results according to the level of nitrogen fertilization on a constant background of P90K90, we observe that nitrogen fertilizers play a decisive role in achieving the production of sweet corn cobs, a fact that is also due to the short vegetation period and the rhythm intense accumulation of dry matter.
