In Bihar, agriculture contributes one-fifth of the state income and employs nearly three-fourth of rural workforce. Agriculture roadmaps implemented in different phases since 2008-09 intend to create the holistic development of the sector with a focus on increasing productivity growth and improving farmers' income. After a few decades of neglect, agricultural sector has been a turnaround in its performance registering appreciable growth rate during the recent years. In 2015-16, contribution of crop sector to overall agricultural output stood at 53.6 per cent. Horticulture accounted for a little less than quarter of output, while field crops constituted roughly one-third of agricultural output. In terms of growth in value of output, field crops and horticulture registered splendid growth rates during the periods of agriculture road maps (2008-09 to 2015-16) as compared to pre-agriculture road map period (2000-01 to 2007-08).
