To reduce the greenhouse gas (GHG) emission from
rice and wheat cultivation several mitigation options
have been suggested. However, economic impact of
these technologies has been poorly documented. In the
present study economic analysis of some emerging
GHG mitigation technologies for rice–wheat system of
the Indo-Gangetic Plains has been carried out. The
experiment consisted of six combinations of wheat–
rice crop rotation using eight treatments, including
conventionally tilled wheat (CTW), zero tilled wheat
(ZTW), transplanted puddled rice (TPR), dry direct
seeded rice (DSR), intermittent wetting and drying
(IWD), application of rice straw (RS) with ZTW and
use of neem oil-coated urea (NOCU) in TPR and
ZTW. Cost of various inputs and income from grain
and straw were used for computing the benefit to cost
(B : C) ratio in the different treatments. ZTW showed
higher yield and B : C ratio compared to CTW along
with reduction in fuel consumption during tillage operation. In spite of lower yield under DSR and IWD,
saving of water, labour and energy in these treatments
lowered the cost of cultivation and enhanced B : C
ratio similar to TPR. Application of rice straw and
NOCU also showed positive impact on crop yield.
B : C ratio of rice–wheat system ranged from 1.62 to
1.86 in the first year and from 1.86 to 2.16 in the second year. B : C ratio was significantly higher in all the
treatments in the experimented rice–wheat system
compared to conventional system, i.e. CTW–TPR. The
ZTW + RR – DSR (WR5) showed highest B : C ratio
followed by ZTW + DSR (WR4) in both the seasons.
