The groundwater resources of semi-arid region
in Indo-Gangetic Plain is declining rapidly and necessitates
accurate quantification of potential recharge from different
agricultural land uses. The potential recharge on a daily
basis for three different land uses, such as fallow, rice and
non-rice cropped areas for three cropping seasons, was
estimated using soil water balance approach. Beside this,
the net groundwater use for eight different crops was also
calculated. The potential recharge from fallow land was
126 mm year-1, which was 14.9 % of total rainfall. The
mean potential recharge from kharif (rainy) and rabi
(winter) seasons was 527.3 and 81.7 mm season,-1
respectively. Among the rabi crops, least recharge was
observed for winter maize and mustard with 29.3 mm
season-1, followed by wheat with 108.4 mm season.
Among the kharif crops, least recharge was observed for
green gram with 59.7 mm season-1, followed by soybean
with 113.9 mm season-1. Rice had the highest recharge
potential of 929.1 mm season-1 , followed by maize with
149.1 mm season-1 and cotton with 132.7 mm season -1.It
was observed that the annual average groundwater use was
highest for wheat with 190 mm year-1, followed by winter
maize with 188 mm year-1, mustard with 169 mm year,-1
paddy with 151 mm year-1, kharif maize with 94 mm year -1
, green gram with 15 mm year-1. Cotton and soybean
crops exhibited an additional potential recharge of 8
and 114 mm year-1into the groundwater. It was revealed
that the maize–wheat cropping system consumed less
groundwater than rice–wheat and, therefore, can be considered
as a better option for sustainable use of groundwater.
