Problems and Stresses that are likely to be encountered by crops of wheat and maize from sowing to harvesting needs to be assessed in order to prepare beforehand. Some of the problems are water stress, waterlogging, frost, soil being too wet for the machinery to operate on land etc.
Temperature：Maize will grow at a temperature of 18°C and 27°C during the day and around nighttime a temperature of 14°C is required. There must be at least 140 frost-free days as it is not frost barred like wheat.
Rainfall：Rainfall must be an annual average of between 60 cm to 110 cm, sometimes it will grow in areas with around 40 cm too.
Soils：Different forms of soils from leached red soil to temperate podzols. However, it grows better in soil of sub tropics where there is a rich content of nitrogen.
Topography：Plain regions, lower slopes of hills. This is a shifting cultivation crop.
