Maize (called corn in some countries) is Zea mays, a member of the family Gramineae|monocot family|liliopsid family} Poaceae. it's a cereal grain that was initial full-grown by individuals in ancient Central America. it's currently the third most significant cereal crop within the world. However, very little of this maize is devoured directly by humans.
Maize, conjointly referred to as corn, could be a cereal grain initial domesticated by endemic peoples in southern Mexico concerning ten,000 years agone. The leafy stalk of the plant produces spore inflorescences and separate ovuliferous inflorescences referred to as ears that yield kernels or seeds, that ar fruits.
Maize (Zea mays L) is one in all the foremost versatile rising crops having wider ability beneath varied agro-climatic conditions. Globally, maize is understood as queen of cereals as a result of it's the best genetic yield potential among the cereals. it's cultivated on nearly one hundred fifty m hour angle in concerning a hundred and sixty countries having wider diversity of soil, climate, multifariousness and management practices that contributes thirty six nothing (782 m t) within the world grain production. The us of America (USA) is that the largest producer of maize contributes nearly thirty five you look after the full production within the world and maize is that the driver of the America economy. The USA has the best productivity (> nine.6 t ha-1 ) that is double than the world average (4.92 t ha-1). Whereas, the typical productivity in Republic of India is a pair of.43 t ha-1
