The maize-wheat-mungbean (MWMb) cropping system is being advocated as an alternative to the
traditional rice-based cropping systems of north-western Indo-Gangetic Plains (IGP) to address the issues
of energy and nutritional scarcity, residue burning, decline in biomass productivity and water tables.
In semi-arid regions, the climate-change-induced variability in rainfall and temperature may have an
impact on phenological responses of cereals and pulses which in turn would affect biomass production,
economic yield and energy and water-use efficiency (WUE) of the crops. Henceforth, quantification of
bioequivalent yields, energy requirement, economics and WUE of MWMb system is essentially required
owing to have better understanding of this cropping system. Following a 4-year study was conducted
under different tillage and nutrient management. ZT and PB plots had significantly higher pooled average
(17.2e20.3%) biomass productivity, (34.4e39.8%) net returns and (49.8e66.2%) biomass water-use efficiency
with lesser (8.5e16.1%) water-use than the CT plots. Significantly higher pooled bioenergetic
yields (21.7e35.2%), net returns (31.4e37.8%) and biomass water-use efficiency (30.1e35.2%) was
observed in SSNM/Ad-hoc plots compared with FFP plots. The total pooled energy input in ZT/PB and
SSNM/Ad-hoc plots was significant (P < 0.05) higher than CT and FFP plots, respectively, with greater net
energy output, energy productivity and energy efficiency. The interactions between tillage and nutrient
management practices on pooled input energy and energy productivity of MWMb system was significant
(P < 0.05). Thus, adoption of conservation tillage (ZT/PB) practices with improved nutrient management
(SSNM/Ad-hoc) could be a viable option for achieving higher biomass productivity, water and energy-use
efficiency and profitability in MWMb system.
