Growth Performance and Resource Use Efficiency of Maize in Bihar: An Economic Perspectives

The present investigation was undertaken to evaluate the growth in area, production and productivity and resource use efficiency of maize in various agro-climatic zones of Bihar. The growth pattern in production and productivity were also observed to be positive and statistically significant. The trends in area, production and productivity were also observed positive for both the growth models, linear and compound.The resource use efficiency was evaluated zone-wise and for state as whole levels using Data Envelopment Analysis (DEA) technique for the block period 2008-09 to 2010-11. Technical efficiencies at state level in maize production were found to be 64% for kharif maize and 71% in rabi maize. Allocative mean efficiencies for kharif and rabi maize were calculated 68% and 65%, indicating that farmers could reduce costs by 32% and 35% by using optimum proportions of inputs considering it’s prices while selecting it’s quantities. Farmers of zone-II of Bihar are well known for large scale production of rabi maize, but still there exist technical inefficiency by 24% and AE by 9%. The value of cost efficiency (CE) emphasizes the reduction of cost by 30% to produce exiting level of output at least cost. The farmers of zone-III are more technically sound as compared to zone-I, zone-II and thus, even at state level too, the TE was observed 88% and 87% for kharif and rabi maize, respectively but AE is very less as compared to other zones i.e. 52% for rabi maize
