Özet
In this study, it was aimed to determine some agricultural characteristics of maize (Zea mays L. indentata) grown in different sowing dates under irrigated Mediterranean conditions. The study was conducted in 2019 and 2020 in Hatay / Turkey, according to split -plots in randomized complete blocks design with three replications. Four different sowing dates (March 1, March 15, April 1, and April 15) were in the main plots and three different commercial hybrid maize cultivars (77MAY35, DKC6630, P2088) were in the sub plots. It was determined that as the sowing date is delayed, the time to reach physiological maturity was shortened and plant height, ear height, thousand kernel weight, biomass yield and grain yield values of cultivars were significantly affected by environmental conditions changing depending on sowing dates. There were no statistically significant differences in grain yield between sowing dates and mean values determined as 1164.8, 1079.0, 1077.5, and 1058.7 kg da-1, in SD2, SD1, SD4, and SD3, respectively. It can be concluded that all of these varieties can be grown by sowing between March 1 and April 15 in regions with similar ecological conditions in the Mediterranean climate zone. Considering the fact that the aim in commercial production is to obtain the highest yield from the unit area, when evaluated in terms of grain yield, the second highest yielding sowing date (March 15) was chosen as the appropriate sowing date for our region.
