Abstract:

With the global climate change, the ecological conditions of the regions have changed over the time. With the change in ecology, the sowing times of the plant species and cultivars cultivated in the region have started to be the subject of research again. This study was conducted to determine the sowing time in the cultivation of grain corn as the main crop in Hatay ecological conditions. P31P41, 70 May 82, DKC 6590 and Carella F1 maize cultivars were used as plant material in the study. Three different sowing times (25 February, 14 March and 30 March) were applied to these varieties, which were selected as plant material and widely cultivated in the region. The experiment was laid out according to the split plot in randomized complete block design with three replications. Ear length, ear diameter, number of rows per ear, number of grains per row of ear, thousand grain weight and seed yield characteristics were investigated in maize cultivars. According to the results of analysis of variance, the effect of sowing times was significant on all traits expect for ear length and ear diameter. According to these results, it was determined that the most suitable sowing time for maize in Hatay ecological conditions was February 25 and March 14.
