Other claims from this paper (13)
- Intervention effect Low light (L1) reduced grain filling, 1000-grain weight and biomass of hybrid rice relative to natural light.
- Intervention effect Low light (L1) reduced harvest index, N uptake and N use efficiency for grain production of hybrid rice.
- Intervention effect Low light (L1) reduced the partial factor productivity of applied N fertilizer in hybrid rice.
- Intervention effect Low light (L1) caused 41.2–53.4% grain yield loss in the two hybrid rice varieties compared with natural light.
- Intervention effect DPRN gave better performance of yield components and N use efficiency than SPHN across two light conditions.
- Association Responses of grain dry weight and yield-attributing traits to light and crop management in the micro-plot were similar to those in field experiments.
- Intervention effect No difference was observed in N uptake from fertilizer, N recovery rate and N retention rate between L0 and L1.
- Intervention effect No difference was observed in N loss rate between L0 and L1.
- Intervention effect DPRN increased N recovery rate by 14.8% compared with SPHN across two light conditions.
- Intervention effect DPRN increased N retention rate by 35.1% compared with SPHN across two light conditions.
- Intervention effect DPRN decreased N loss rate by 29.4% compared with SPHN across two light conditions.
- Association Differences in responses of grain yield and related parameters to low light between the two cultivars were small.
- Recommendation DPRN is feasible to increase grain yield and N use efficiency for hybrid rice grown under two light conditions.
