Other claims from this paper (8)
- Intervention effect Supplementary irrigation at overwintering and budding stages improved main quality indexes and yield of winter oilseed rape
- Intervention effect Under supplementary irrigation at I2, LAI, aboveground biomass and chlorophyll content first increased and then decreased as N application rate increased, reaching maximum at medium N rates
- Intervention effect Under supplementary irrigation at I2, water use efficiency, N accumulation and N agronomy efficiency first increased and then decreased as N application rate increased, reaching maximum at medium N rates
- Intervention effect Under supplementary irrigation at I2, yield of winter oilseed rape first increased and then decreased as N application rate increased, reaching maximum at medium N rates
- Intervention effect Under the same irrigation level, grain oil content of winter oilseed rape decreased as N application rate increased
- Intervention effect Under the same irrigation level, protein and thioside acid content of winter oilseed rape increased as N application rate increased
- Recommendation The multi-objective optimal water-N strategy was supplementary irrigation at overwintering and budding stages combined with 200 kg/hm2 N
- Method / resource The TOPSIS with Nash equilibrium-combination weighting method gave more reasonable evaluation results than subjective and objective weighting methods
