Other claims from this paper (11)
- Intervention effect Grain legumes (chickpea and lentil) had higher productivity than oilseed crops in rice-fallow conditions.
- Intervention effect ZTDSR R+ and ZTDSR treatments increased grain yield of all winter crops over PTR.
- Mechanism The grain yield gain under ZTDSR treatments was attributed to higher soil moisture retention (authors suggest).
- Intervention effect Conservation tillage increased safflower grain yield by 190%.
- Intervention effect Conservation tillage increased lentil grain yield by 93%.
- Intervention effect Conservation tillage increased chickpea grain yield by 70%.
- Intervention effect Conservation tillage (ZTDSR, ZTTPR) reduced energy use by 11–20% relative to conventional tillage.
- Intervention effect Conservation tillage increased the energy ratio over conventional tillage, higher in rice-safflower, rice-lentil and rice-chickpea rotations.
- Intervention effect Higher net return was attained in rice-safflower and rice-chickpea rotations with ZTDSR R+ treatment.
- Intervention effect Predicted greenhouse gas emission was reduced by 30% under ZTDSR compared with ZTTPR and PTR.
- Recommendation Winter crops such as chickpea, lentil and safflower after conservation tillage (ZTDSR R+ in particular) are suggested as strategic options for higher system productivity, economic returns and energy use efficiency with reduced greenhouse gas emission.
