e1“2-year mean maize, wheat and chickpea grain/seed yield was found to be 17.0-23.2, 20.8-24.8 and 22-31.7% higher under CA-based PB+R/ZT+R than CT-R, but it was 5.3-10.9, 4.9-8.4 and 13.8-22.8% higher than CT+R, respectively”

- Intervention effect Two-year mean wheat grain/seed yield was higher by 20.8-24.8 under CA-based PB+R/ZT+R than under CT-R.
- Intervention effect Two-year mean chickpea grain/seed yield was higher by 22-31.7% under CA-based PB+R/ZT+R than under CT-R.
- Intervention effect Two-year mean maize grain/seed yield was higher by 5.3-10.9 under CA-based PB+R/ZT+R than under CT+R.
- Intervention effect Two-year mean wheat grain/seed yield was higher by 4.9-8.4 under CA-based PB+R/ZT+R than under CT+R.
- Intervention effect Two-year mean chickpea grain/seed yield was higher by 13.8-22.8% under CA-based PB+R/ZT+R than under CT+R.
- Intervention effect The yield of maize was significantly (P<0.05) higher in CA-based PB+R and ZT+R systems than in CT-R from the first year onwards.
- Intervention effect The yield of wheat was significantly (P<0.05) higher in CA-based PB+R and ZT+R systems than in CT-R from the first year onwards.
- Intervention effect The yield of chickpea was significantly (P<0.05) higher in CA-based PB+R and ZT+R systems than in CT-R from the first year onwards.
- Intervention effect Two-year mean system productivity of the maize-wheat rotation (maize equivalent yield) was higher by 21.1-21.9% in CA-based systems (PB+R & ZT+R) than in CT-R.
- Intervention effect Two-year mean system productivity of the maize-chickpea rotation (maize equivalent yield) was higher by 18.7-27.5% in CA-based systems (PB+R & ZT+R) than in CT-R.
- Intervention effect CA-based PB+R and ZT+R practices reduced total system water use in the maize-wheat rotation by 75-112 mm compared with CT-R.
- Intervention effect CA-based PB+R and ZT+R practices reduced total system water use in the maize-chickpea rotation by 55-90 mm compared with CT-R.
- Intervention effect CA-based PB+R and ZT+R practices enhanced system water productivity in the maize-wheat and maize-chickpea rotations compared with CT-R.
- Intervention effect Residue management treatments enhanced soil moisture by 14.5 to 30.4% during winter and monsoon seasons, irrespective of crop rotation and tillage and establishment practice.
- Intervention effect Residue management treatments also moderated soil temperatures, irrespective of crop rotation and tillage and establishment practice.
- Intervention effect Economic profit of the maize-wheat rotation was always significantly (P<0.05) higher, by 168-445 US$/ha/year, in CA-based systems than in CT-R.
- Intervention effect Economic profit of the maize-chickpea rotation was always significantly (P<0.05) higher, by 215-619 US$/ha/year, in CA-based systems than in CT-R.
- Recommendation The authors conclude that maize-wheat and maize-chickpea rotations under a CA-based system are one way to improve crop productivity, water productivity and farm income with less risk of extreme temperature and moisture stress while sustaining natural resources.
