Sweet corn is a relatively new crop for our country and with certain peculiarities compared to conventional corn cultivation technology. The aim of this study is to contribute to the improvement of cultivation technology in relation to pedoclimatic conditions in the Berzovia area, by studying the relationship between cob weight and production of sweet corn cobs according to the maturity group in an assortment of 11 sweet corn hybrids compared with the local hybrid Estival. The study was carried out in the Ramna area, characterized by an early spring, the minimum germination temperature of 10oC, taking place in the first days of April, a fact that allows obtaining early harvests. The results highlighted that the highest cob weight values were obtained in hybrids: Driver F1, Accentuate F1 and 11-Sweet Thing, between 336 and 368 g. Small cob weight values of approximately 232-255 g were obtained in hybrids the extra-early Estival and Spirit F1, the early Legend F1, Tyson F1, Starshine F1 and the semi-early hybrid Landmark F1. Regarding the production of sweet corn, SF201 F1, Jubilee F1, Driver F1, Accentuate F1 and Sweet Thing hybrids were well above the experience average in terms of cob production, surpassing the field average with gains between 2392.43 kg/ha and 5224.59 kg/ha, or in other words: the five hybrids surpassed the control by: 12.56%, 16.50%, 27.43%, 17.68%, respectively 16.76%.
