Intervention effect Hairy vetch mulching on high-fertility soil gave the best cover-crop nutrient inputs.
Intervention effect Ryegrass produced substantially more biomass.
Mechanism Ryegrass biomass improved weed control.
Intervention effect Ryegrass and hairy vetch did not differ significantly in cover-crop nutrient inputs.
Intervention effect Ryegrass and hairy vetch did not differ significantly in rice grain and straw yields.
Mechanism High ryegrass biomass led to the highest methane emissions during rice cropping.
Intervention effect Green mulching controlled weeds more effectively than green manuring.
Association The difference in weed control influenced rice growth and yield.
Intervention effect Avoiding straw incorporation before hairy vetch and mulching did not affect weed infestation.
Intervention effect Avoiding straw incorporation lowered soil available nitrogen.
Intervention effect Avoiding straw incorporation did not affect rice growth or grain yield.
Association Higher soil fertility promoted cover-crop development and nutrient inputs.
Association Higher soil fertility promoted rice growth and grain yields.
Association Higher soil fertility was associated with higher methane emissions.
Recommendation The authors recommend management to mitigate high methane emissions associated with added organic matter.
