It is an important food staple in many countries and is also used in animal feed and many industrial applications. The crop has tremendous genetic variability, which enables it to thrive in tropical, subtropical, and temperate climates. Global production of maize has grown at a calculated annual growth rate (CAGR) of 3.4 per cent over the last ten years, from 717 million metric tons (MnMT) in 2004-05 to 967 MnMT in 2013-14. Maize is grown throughout the year in India. It is predominantly a kharif crop with 85 per cent of the area under cultivation in the season. Maize is the third most important cereal crop in India after rice and wheat. It accounts for ~9 per cent of total food grain production in the country. Maize production in India has grown at a CAGR of 5.5 per cent over the last ten years from 14 MnMT in 2004-05 to 23 MnMT in 2013-14. During 2009-10 there was a decline in production primarily due to drought that affected production of kharif crops in the country. The area under maize cultivation in the period has increased at a CAGR of 2.5 per cent from 7.5 Mn hectare in 2004-05 to 9.4 Mn hectare in 2013-14, the remaining increase in production is due to increase in yield (India International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 7 Number 08 (2018) Journal homepage: http://www.ijcmas.com The present study has been undertaken to study the trends, prediction model of area, production and productivity of maize in Northern Hills of Chhattisgarh in India. Time series data for maize were collected for the period from 1979-80 to 2012-13 from various governmental publications and web sites. The whole period divided into three sub periods (Period-I, 1979-80 to 1986-87; Period-II, 1987-88 to 1997-98 and Period-III, 1998-99 to 2013-13) for trends analysis and for prediction model. The linear, quadratic and exponential function are fitted in order to analyse the trend in area, production and productivity of maize crop. Besides these, compound growth rate, coefficient of variation (CV), instability index of area, production and productivity of maize crop have also been estimated and discussed. The result of the study revealed that the growing of crop is not risky as the CV of area, production and productivity of crop are very less.
