Maize (Zea mays L.) is cultivated widely throughout the world and has the highest production of all the cereals. Worldwide, production of maize was more than 844.36 MT (FAO, 2017) and productivity of 5.22 t ha -1 . It is an important staple food in many countries and also used as animal feed and has many industrial applications. Owing to its tremendous genetic variability, the maize crop thrives well in a wide range of environments from tropical to temperate climate (Anon., 2014). Maize is grown in climates ranging from temperate to tropical during the periods when mean daily temperatures are above 15°C and frost-free. The productivity of maize in India has been reported to 1566 kg ha -1 during 2015-16 which has doubled since 2006 (DES, 2015-16).
