Odisha State has about 6.5 million hectares of cultivable area out of the total geographical area of 15.6 million ha, accounting for 41.16%. Rice is the main crop of the State covering 75-80% of the total cultivated area with 3.8 million ha (Source: Odisha Agriculture Statistics 2013-14 ). A large portion of potentially productive cropland in Odisha remains fallow during the winter (Rabi) season after the monsoon (Kharif) rice season due to several constraints. An estimate of nearly 2 million ha remains fallow in the winter season in the state.
