The research was conducted in the Banat Plain, located in the west part of Romania. This area is favourable for the sweet corn crop especially due to climate and soil conditions. The soil type in the experimental field is a mild eutricambosoil, moderately gleaned, moderately decarbonated, on medium /coarse fluvial deposits, medium clay, with weak acidic reaction, a 6.10 pH value in the 0-27 cm horizon, the humus content is medium to good (2.58%), the supply with phosphorus and potassium is medium to good. The climate is temperate continental, with an average annual temperature of 10.6 °C and an average precipitation value of 605 mm. The experiments were bi-factorial, factor A - the sowing period (season I, 10-15 April, season II, 20-25 April, season III, 1-5 May), and factor B - the hybrid cultivated (Prima, Summer Delight and Estival created at SCDA Turda). Fertilisation was done uniformly with N 150 P 80 K 80. The summary of the harvest results shows that, on average, the yield of corncobs harvested at maturity for the three hybrids was 12,786 kg / ha in season I, 14,374 kg / ha in season II, and 13,817 kg / ha in season III. The yields of the hybrids for the three planting seasons were 14 123 kg / ha for Prima hybrid, 13 478 kg / ha for Summer Delight hybrid and 13 376 kg / ha for Estival hybrid. At harvest, measurements were made regarding the water content of the kernels, as well as the carbohydrate, protein and fats content. The results are presented in the paper according to hybrids and sowing seasons, as well as the results of physical analyses at MMB and the yield of raw kernels.
