Different Hybrid Cultivars and Seed Sowing Time of Sweet Corn (Zea mays L. var. saccharata) Effect on Physical Properties

Abstract

The aim of this study, which was made in order to consider the increasing production of sweet corn on earth to determine sweet corn varieties and planting times that previously not raised at high altitudes. This study was conducted in Van, which has an altitude of 1720 m. 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 evaluated in 2014, 2015 and both year average. In the light data we have obtained in our research, in sweet corn varieties the highest cob volume (317.5 cm³), highest husked cob weight (363.0 g ) and highest number of kernel on cobs (592.9) was obtain from cv. Challenger. The highest dry matter content was obtain from cv. Overland. The cob diameter characteristic between the varieties was found to be insignificant. In addition to it was determined that the earliest cultivar was Overland, but the latest one was Syngenta-8529. It was determined that the most suitable seed sowing time for sweet corn in high altitudes regions was between June 24th and July 8th.
