Two of the most pressing sustainability issues
are the depletion of fossil energy resources and the
emission of atmospheric green house gases like carbon
dioxide to the atmosphere. The aim of this study was to
assess energy budgeting and carbon footprint in transgenic
cotton–wheat cropping system through peanut
intercropping with using 25–50 % substitution of recommended
dose of nitrogen (RDN) of cotton through
farmyard manure (FYM) along with 100 % RDN
through urea and control (0 N). To quantify the residual
effects of previous crops and their fertility levels, a
succeeding crop of wheat was grown with varying ratesof nitrogen, viz. 0, 50, 100, and 150 kg ha-1. Cotton+
peanut–wheat cropping system recorded 21 % higher
system productivity which ultimately helped to maintain
higher net energy return (22 %), energy use efficiency
(12 %), human energy profitability (3 %), energy productivity
(7 %), carbon outputs (20 %), carbon efficien-
cy (17 %), and 11 % lower carbon footprint over sole
cotton–wheat cropping system. Peanut addition in cotton–wheat
system increased the share of renewable
energy inputs from 18 to 21 %. With substitution of
25 % RDN of cotton through FYM, share of renewable
energy resources increased in the range of 21 % which
resulted into higher system productivity (4 %), net energy
return (5 %), energy ratio (6 %), human energy
profitability (74 %), energy productivity (6 %), energy
profitability (5 %), and 5 % lower carbon footprint over
no substitution. The highest carbon footprint (0.201)
was recorded under control followed by 50 % substitution
of RDN through FYM (0.189). With each successive
increase in N dose up to 150 kg N ha-1to wheat,
energy productivity significantly reduced and share of
renewable energy inputs decreased from 25 to 13 %.
Application of 100 kg N ha-1to wheat maintained the
highest grain yield (3.71 t ha-1), net energy return
(105,516 MJ ha-1), and human energy profitability
(223.4) over other N doses applied to wheat. Application
of 50 kg N ha-1to wheat maintained the least
carbon footprint (0.091) followed by 100 kg N ha
(0.100). Our study indicates that system productivity
as well as energy and carbon use efficiencies of trans-
genic cotton–wheat production system can be enhanced
by inclusion of peanut as an intercrop in cotton and
substitution of 25 % RDN of cotton through FYM, as
well as application of 100 kg N ha-1to succeeding wheat crop.
