The aim of this study was to investigate the grain yield and some yield components ofsome maize varieties cultivated in Çukurova conditions under double crop conditions. Theexperiment was conducted in 2014 in the Eastern Mediterranean Agricultural ResearchInstitute, Doğankent location in a randomized block trial design with four replications. Four mid-early hybrid maize varieties (71MAY69, 72MAY80, 32T83 and 31P41) were used asmaterial in the study.According to the average values obtained in the study, plant height was between 211,0 –182,4 cm, plant dry biomass weight was between 27,4 – 35,4 t/ha, harvest index was between23,5 – 33,2%, number of seeds in cob was between 615,4 – 698,8 pieces/cob, 1000 grainweight was between 207,0 – 292,0 g, grain yield was between 8,2 – 10,1 t/ha. According tothe results of the research, the highest grain yield of 1,01 t/ha was obtained from P32T83variety where yield values of other varieties were found to similar and lower.
