Other claims from this paper (9)
- Intervention effect Wheat biomass, grain yield and N and P uptake did not differ significantly between intercropping and sole cropping at the same fertilization level.
- Intervention effect Poplar intercropping reduced fertilized maize biomass by 37%.
- Intervention effect Poplar intercropping reduced fertilized maize grain yield by 31%.
- Intervention effect Poplar intercropping reduced unfertilized maize biomass by 28%.
- Intervention effect Poplar intercropping reduced unfertilized maize grain yield by 34%.
- Intervention effect Intercropped maize had significantly lower N and P contents than sole maize.
- Intervention effect Under fertilization, poplar intercropping increased soil NO3-N and Olsen-P during active maize growth.
- Intervention effect Without fertilization, poplar decreased soil NO3-N and Olsen-P in both wheat and maize seasons.
- Recommendation The authors recommend sufficient available nutrients for agroforestry, especially during intercrop active growth.
