Foodgrain requirements of India (both human and cattle)
are estimated at 300 million tonnes in 2020 (Sinha et al.
1998). With the alarming increase in GHG concentration and
its expected impact on climate, the issue emerging would be
to achieve the targeted production. To address the above issue
from the agricultural point of view, it is desirable to select
the crops and their cultivars thereof, that can better utilize
the increased concentration of CO2 for both biomass and
grain yield.
In case of food legumes where grain is harvested for
human consumption, the translation of increased biomass
more towards grain or improved harvest index need to be
achieved for breaking the yield barriers of these very
important C3 grain legumes predominantly grown in the
marginalized rainfed areas. India is the largest producer and
consumer of pulses in the world. India grows pulses in about
22.5 million ha and 80% is in dry areas. However, pulses
production has been stagnant at between 11 and 14 million
tonnes over the last two decades. Per capita pulses
consumption over the years has come down from 61 g/day
in 1951 to 30 g/day in 2008 (Amarender Reddy 2009).
Elevated CO2 condition appears to improve the overall
growth of plants in general and may result in changes in
partitioning of photo assimilates to various plant organs over
time. An attempt was made to quantify the response of two
major rainfed grain legume crops, viz pigeonpea and
blackgram to increased atmospheric CO2 level in terms of
