Other claims from this paper (14)
- Intervention effect Compared with conventional nitrogen fertilization, 25% and 35% nitrogen reduction reduced leaf area index and net photosynthetic rate of peanut.
- Intervention effect Compared with conventional nitrogen fertilization, 25% and 35% nitrogen reduction reduced 100-fruit weight, 100-kernel weight and yield of peanut.
- Intervention effect The 25% and 35% nitrogen reduction treatments had no significant effect on kernel rate of peanut compared with conventional nitrogen fertilization.
- Intervention effect With constant nitrogen fertilizer, adding organic fertilizer alone increased leaf area index, chlorophyll and net photosynthetic rate of peanut.
- Intervention effect With constant nitrogen fertilizer, adding organic fertilizer alone increased peanut yield.
- Intervention effect In compounded treatments, the highest peanut yields were achieved with 25% N reduction plus 3000 kg/hm-2 organic fertilizer (T3) and plus 4500 kg/hm-2 organic fertilizer (T4).
- Intervention effect Net photosynthetic rate and leaf area index of peanut were significantly higher in T3 and T4 than in the conventional fertilizer treatments.
- Intervention effect Yield and fertilizer contribution of peanut were significantly higher in T3 and T4 than in the conventional fertilizer treatments.
- Intervention effect Nitrogen fertilizer had significant effects on the quantity and fresh weight of peanut root nodules.
- Intervention effect Nitrogen reduction increased the quantity and fresh weight of peanut root nodules in the early stage of fertility.
- Intervention effect Nitrogen reduction decreased the quantity and fresh weight of peanut root nodules in the harvest stage.
- Association The property of root nodules was significantly positively correlated with net photosynthetic rate and yield in peanut.
- Mechanism The authors suggest that the root nodule correlations with photosynthesis and yield may be the mechanism of the highest yields in T3 and T4.
- Recommendation The work is said to support a balanced fertilization strategy and high-yielding, efficient cultivation of peanut.
