Özet

Sweet corn is an attractive crop due to its high yield per unit area, short vegetation period and a good plant in crop rotation. In order to determine the suitable sweet corn varieties for Erzurum region, this research was carried out in Ataturk University Plant Production Application and Research Centre, during the 2017 and 2018 cropping seasons. Randomized complete block design was used; some traits of the varieties related to growth, yield and quality was investigated. A significant difference was determined among the varieties in terms of the investigated traits. In terms of days to silking (SD), the mean values ranged between 76.17-90.67 days, days to maturity (MD) was between 105.67-120.17 days, plant height (PH) was between 169.97-215.97 cm, number of tillers per plant (NT/P) was between 0.13-1.50, number of leaves per plant (NL/P) was between 8.92-10.95. The number of ears per plant (NE/P) was between 0.98-1.28, first ear height (FEH) was between 37.25-77.75 cm, number of plants per hectare (NP/ha) was determined between 66388.83-79166.67, dehusked ear yield (EY) was ranged between 9442.89-18790.44 kg/ha. The number of marketable ears per hectare (NME) was between 12611.06-66944.50 and the yield of marketable ears (YME) was found between 3205.00-16858.28 kg/ha. Concerning the number of kernel rows per ears (NKR/E) was between 14.12 and 18.93, number of kernels per row (NK/R) was determined between 30.77-40.33, number of kernels per ear (NK/E) was counted between 461.14-719.23, fresh kernel yield (FKY) was measured to be between 1681.50-11855.00 kg/ha; the green mass yield was determined between 35458.33 and 49406.33 kg/ha. In terms of DM, EY, yield of the fresh kernel and marketable ear Signet variety, whereas in terms of the ear yield, yield of marketable ear, and number of marketable ears Khan F1 variety has attracted attention for they were on the first ranks. Based on the results of the combined two-year research, Signet variety can be the first suggestion for the production of sweet corn for fresh consumption in Erzurum whereas the second choice is Challenger variety.
