Abstract

Production and consumption of sweet corn in the world have been increasing. In this context, the aims of our study were to provide an alternative product in high altitude where sweet corn is not common and to determine the yield and quality criteria of different sweet corn cultivars and different seed sowing time in this region, Van (Turkey) having 1720 m altitude. In the study, four hybrid sweet corn (Challenger, Overland, Jubilee and 8529) and one control hybrid maize (3167) were evaluated at four different sowing times (May 27th, June 10th, June 24th and July 8th) in 2014 and 2015. At the end of the study, revealed significant difference of sowing date and cultivars on all yield components. It was determined that the most suitable seed sowing time for sweet corn was between June 24th and July 8th and Challenger was the most suitable cultivar at high altitude.

Conclusion

It was determined that increasing soil and ambient temperatures resulted in positive outcomes for the sweet corn that reacts well to warm temperatures and caused increases in cob length, unhusked cob weight, cobs number per plant and these increased resulted in a better yield. The properties investigated in the current study are the basic parameters that affect the yield and the quality. It was determined that these parameters vary with sowing periods and cultivars used. It was further identified that cv. Challenger performed the best with respect to all investigated parameters. Larger kernel and high kernel weight of cv. Challenger render this cultivar more usable for canning and frozen food industries when compared to other cultivars. The present study conducted in Van region showed that the earliest cultivar was Overland and the latest one was 8529. It was found that sweet corn cultivars matured earlier than cv. 3167 which is control maize. As a result, it was determined that 17
