Production and consumption of sweet corn in the world has been increasing. In this context, the aims of our study were to provide an alternative product in the region and to determine the yield and quality criteria of different sweet corn cultivars and different seed sowing time in the Van region. In this study, 4 hybrid sweet corn cultivars (Challenger, Overland, Jubilee and Syngenta-8529) and 1 normal corn cultivar (Pioneer-3167) were evaluated in 4 different sowing times (May27th, June10th, June 24th and 8 July 8th). The study was conducted as a random split plot design with three replications. The study was evaluated in 2014, 2015 and both year average.In the light data we have obtained in our research, in sweet corn varieties the highest total husked ear yield (29 828 kg ha-1) was obtained from cv. Challenger, while the lowest value (24 858 kg ha-1) was obtained from cv. Overland. It was determined that the earliest cultivar was Overland, but the latest one was Syngenta-8529. In terms of the amount of TSS, cv. Challenger had the highest TSS value (23.7 Brix°), while cv. Overland had the lowest TSS value (21.0 Brix°). In terms of all traits, it was determined that cv. Challenger was the most suitable cultivar for Van region.It was determined that the most suitable seed sowing time for sweet corn in Van region was between June 24th and July 8th. All cultivars were adapted to the Van region. However, in terms of all traits, the most prominent sweet corn cultivars were Challenger and Syngenta-8529.
