Conventional agriculture is energy and carbon intensive. Single and double-crop basis residue-mulching in zero-tilled crop-sequences may minimize carbon-footprint with improved crop and energy productivity in water-scarce ecologies. Zn-fertilization is also vital for drought-stress tolerance besides enhanced productivity and quality in Zn-deficient arid-soils. Hence, we compared the single and double-crop basis residue-mulching alongwith Hydrogel and Zn-fertilization in zero-tilled pigeonpea-wheat system. Results showed that double-crop residue-mulching + Hydrogel exhibited ∼22.3 and 17.1% higher system-productivity over no-residue and single-crop residue-mulching plots while maintaining higher net-returns (1315 US$/ha). Crop-residue covering consumed considerable energy (77.3–89.1% of total consumption) and carbon (5–10 folds). Thick residue-cover (8 t/ha/year) under double-crop residue-mulching + Hydrogel exhibited significantly higher energy-output (238,328 MJ ha−1), energy-intensiveness (107.3 MJ/US$) and specific energy (20.15 MJ kg−1) compared to single-crop residue-mulching; whereas energy-use efficiency, energy productivity and profitability were higher under no-residue cover. Zn-fertilization (5 kg ha−1) alongwith Zn-solubilizer in both crops also enhanced the biomass and energy productivity over sole-Zn or no-Zn. Interestingly, carbon footprints increased with residue-covering (4–8 t/ha/year) while least under no-residues. Therefore, farmers should preserve a balance while mulching the residues in single or both crops besides necessitating Zn-fertilization in Zn-deficient arid and semi-arid regions where livestock equally competes for residues as quality fodder.

‘Participatory-mode’ adaptive research was conducted in wheat in north-western Himalayas (NWH) during 2008–2014 to develop an improved chemical weed management (ICWM) technology. First of all, two years ‘on-farm experimentation’ was performed in a randomized block design at 10 locations in NWH using seven treatments (Clodinafop @ 60 g a.i./ha (Clod); Clod followed by 2,4-D (Na-salt) @ 1.0 kg a.i./ha (Clod-fb-D); Isoproturon 75 WP @ 1.0 kg a.i./ha (Iso); Iso + D; Sulfosulfuron 75% WG @ 25 g a.i./ha + Metsulfuron 5% WG @ 2 g a.i./ha (Sulf + Met); weed-free-check; and un-weeded-check). In this study, the post-emergence application of Sulf + Met reported the lowest weed-index and NPK depletion by weeds with higher weed control efficiency (86.4%), weed control index (81.1%) and herbicide efficiency index (2.62) over other herbicides. Sulf + Met exhibited significantly higher wheat productivity (3.57 t/ha), protein yield, net-returns and water-productivity, which was followed by Iso + D and Clod-fb-D, all of which remained statistically at par with each other. An impact assessment of intensive technology-transfer programme (2008–2014) revealed a higher technology adoption rate (71–98%) of ICWM leading to higher wheat productivity (~22%) and net income gains (2.8–26.4%) in NWH. Overall, Sulf + Met proved highly effective against mixed weed flora in wheat to boost wheat productivity, profitability, quality and water productivity in addition to a higher technology adoption rate and NIGs to transform rural livelihoods in NWH.
