The most important factors that determine the limits of corn growing are temperature and growing period. Although corn is a hot climate plant, it does not require excessive heat. Under normal conditions, it starts to germinate around 10- 11 ° C, and when the soil temperature reaches 15° C, the germination speed increases. For a good development, the moisture must be sufficient (relative humidity 60%) and properly distributed in the soil. Although it is grown in various soil types, it is advantageous to grow in well-ventilated, drained, loamy and organic matter rich soils. Since it is sensitive to soil acidity, the recommended soil pH varies between 6.0 and 7.2. Depending on the variety, climate and soil conditions, the development period is over 110 days with exceptions.
