For identification and adoption of improved and environmental friendly
agricultural practices with minimum emission of greenhouse gases
(GHGs), observations were recorded for 3 years (2015–17) in a 22-yearold
soybean-wheat based long-term fertilizer experiment that was started
in 1995–96. The study involved seven treatments: control (CK), organic
manure (M), inorganic fertilizers (NPK), integrated (MNPK), only nitrogen
(N), mineral fertilizers in both season (NPK+NPK) and nitrogen with
organic manure (MN). MNPK significantly enhanced the system productivity
(9.72 Mg ha−1) with higher net return (3128 US$ha−1) and benefitcost
ratio (1.64). Due to better energy output to inputs relation, total
energy productivity and energy use efficiency were reported higher in
MNPK (0.38 kg MJ−1 and 4.76, respectively) followed by MN (0.34 kg MJ−1
and 4.26, respectively) and M (0.32 kg MJ−1 and 4.16, respectively). In
contrast to C efficiency, C sustainability index and yield scaled carbon
footprint (CFy), the spatial CO2-e emission (CFs) was found highest under
MNPK (~5035 kg CO2-e ha−1) followed by MN and NPK+NPK and lowest
was recorded under control. In sum, long-term organic and inorganic
fertilization simultaneously in soybean-wheat system may be a preferred
strategy for improving soil productivity, profitability, energy use and
environmental sustainability of Indian-mid-Himalayas.
