Determination of the yield and quality characteristics of some corn (Zea mays L.) varieties under menemen conditions

Objective: This study was carried out to determine the yield and quality of some maize cultivars under Menemen conditions. Material and Method: The field experiment was established in the main crop conditions of 2021 in menemen conditions, according to the randomized blocks trial design with 3 replications. DKC6980, M14G44, P2088, Sy Giants, Sy Gladius and Kefrancos varieties were used as an experimental materials. Results: Seed yield varied between 12217 – 15699 kg/ha. Thousand seed weight varied between 339.00 – 419.25 g. The highest thousand seed weight was obtained from Kefrancos variety. The number of seeds on the cob varied between 599.65 – 715.43 pieces. The protein ratio in the seed ranged from 8.28% to 9.65%. The highest protein content was obtained from Sy Giants and Kefrancos cultivars. Crude fat ratio varied between 2.82% and 3.59%. The highest crude oil ratio was obtained from P2088 variety. In terms of amino acid amounts, glutamate varied between 1.29 - 1.47 g/100g, proline between 0.60 - 0.67 g/100g, lysine between 0.72 - 0.79 g/100g. Conclusion: According to the results of the research, the seed yield of the cultivars was above the average of the region yield. DKC 6980 and Kefrancos varieties came to the fore in terms of seed quality, SY Giants and Kefrancos varieties in terms of seed protein content and P2088 varieties in terms of crude oil content. It was concluded that these cultivars are suitable for seed maize cultivation in Menemen conditions. Keywords: Maize, Seed yield, Amino acid, Ash content
