Determination of the effect of different sowing times on grain yield and some plant characteristics of dent corn (Zea mays L.) in çukurova region conditions

This research was conducted to determine the effects of different sowing times (1 February, 20 February, 10 March, 30 March, 20 April) on grain yield and several plant characters of dent corn (DKC 6761, DKC 5364 and 72 MAY 80) in the main product conditions of Çukurova Region, in the Research and Application Area of Cukurova University Faculty of Agriculture, Department of Field Crops, according to split plot design with three replication.. According to the results obtained from the research, the effect of different sowing dates wasn't significant for plant height, first ear height, stem diameter, ear grain ratio and 1000 grain weight, while significant for ear lenth, ear diameter, number of grains per ear, single ear weight, grain weight per ear, hectolitre weight, moisture content and grain yield. It was determined that the highest grain yield was obtained from DKC 6761 maize variety (1320.00 kg / da) from the 30 March sowing.
