Other claims from this paper (13)
- Intervention effect Relay-intercropped hairy vetch was established without reducing broccoli yields.
- Observation Average aboveground biomass of hairy vetch was 3400 kg dry weight per hectare.
- Observation Hairy vetch biomass provided a nutrient input of 125 kg N per hectare.
- Observation Hairy vetch biomass provided a nutrient input of 27 kg P2O5 per hectare.
- Observation Hairy vetch biomass provided a nutrient input of 88 kg K2O per hectare.
- Observation The three hairy vetch varieties differed significantly in C:N ratio.
- Observation Massa and Namoi hairy vetch varieties had higher C:N ratios.
- Observation The Savane hairy vetch variety consistently had the lowest C:N ratio.
- Intervention effect In the second year, the conventional treatment significantly outperformed the Massa hairy vetch treatment for sweet corn.
- Intervention effect Namoi and Savane showed superior fertilizer effects compared with Massa.
- Mechanism The superior fertilizer effects of Namoi and Savane were likely due to their lower C:N ratios.
- Intervention effect The fertilizer effect of hairy vetch was slightly inferior to chemical fertilizers in the long term.
- Recommendation Relay intercropping hairy vetch can significantly reduce chemical fertilizer requirements in broccoli-sweet corn systems without compromising the primary crop yield.
