Rice is the principal crop during kharif (rainy) season
in eastern India, which occupies 26.8 M ha accounting
for 63.3% of the total rice-growing areas of the country.
However, this area is not fully utilized for crop
production in the subsequent rabi (post-rainy) season
and kept fallow due to a number of biotic, abiotic and
socio-economic constraints. If this rabi fallow area can
be effectively utilized, it will help in improving the
economy of this region, which is yet to be benefited
from the green revolution. The objectives of the present
study include: (i) delineation of rabi fallow areas
of eastern India using remote sensing and GIS technique;
(ii) characterization of soil resources of the rabi
fallow regions, and (iii) suggesting site-specific crop
planning for this region. It was estimated that about
12.54 M ha area in the rabi season is left fallow in
eastern India. The soil properties like soil texture, soil
moisture retention at field capacity and permanent
wilting point, saturated hydraulic conductivity, soil
pH, electrical conductivity, soil organic carbon, etc.
were determined at the representative profiles distributed
in different agro-ecological sub-regions
(AESRs) of this region and mapped in a GIS environment.
Using water balance studies, site-specific crop
planning based on available residual soil moisture has
been suggested. In most of the AESRs, pulses and oilseeds
like green gram, black gram, Sesamum and
mustard can be grown successfully on residual soil
moisture content. Crops which suffer from water deficit
during maturity stages can also be grown during
rabi season with one or two supplemental irrigations,
wherever possible. If the site-specific constraints to
crop production can be alleviated and these fallow
lands can be brought under cultivation through proper
crop planning as suggested, poverty in this resourceful
region can be eradicated to a great extent.
