A comparative study on area, production, yield and stability of maize in northern and southern districts of Karnataka

Abstract

A comparative study on area, production, yield and stability of maize in northern and southern districts of Karnataka was conducted, Northern and southern districts of Karnataka were purposively selected due to their major contribution in maize production. Among the northern districts, Belagavi and Haveri and among southern districts, Davangere and Chitradurga had the highest area and production under maize in 2016. Karnataka state is famous for maize production and industrial glucose extraction. Growth in area, production and yield of maize in northern and southern districts of Karnataka was worked out. Right from 2000 to 2014 it was found that northern Karnataka had higher area, production and yield of maize. Area, production and yield ranged from 26, 613 to 62, 103 ha, 52, 997 to 3, 63, 803 MT and 1.80 to 4.65 tonnes per ha respectively in northern Karnataka in comparison to 17, 289 to 41, 901 ha, 36, 217 to 1, 36, 537 MT and 1.88 to 3.49 tonnes/ha respectively in southern karnataka. The compound annual growth rate of area, production and yield under maize in northern Karnataka was estimated at 6.51, 7.55 and 1.07 per cent respectively. In case of southern Karnataka growth in area, production and yield increased by 6.90, 9.38 and 2.50 per cent respectively. Average instability in area, production and yield of maize in northern and southern Karnataka was worked out and it was estimated to be 58, 65 and 37 per cent for northern Karnataka and 51, 59 and 44 per cent respectively for southern Karnataka. Hence it could be inferred that northern Karnataka had higher instability in production and yield and southern Karnataka in area.
