Other claims from this paper (16)
- Intervention effect Light interception rate, sheath blight disease incidence and disease index differed significantly among nitrogen management methods in rice.
- Intervention effect Total dry matter differed significantly among nitrogen management methods in rice.
- Intervention effect Radiation use efficiency of rice increased at a certain level of applied N.
- Intervention effect Harvest index of rice decreased as applied N increased.
- Association Grain yield of rice has a quadratic relationship with applied N rate.
- Intervention effect Different fertilizer-N application methods affected radiation use efficiency and grain yield of rice at the same N rate.
- Intervention effect Fungicide application improved canopy light interception rate, radiation use efficiency and grain filling of rice relative to no fungicide.
- Intervention effect Fungicide application improved harvest index of rice relative to no fungicide.
- Intervention effect Fungicide application reduced the degree of sheath blight disease in rice relative to no fungicide.
- Intervention effect Fungicide application decreased and delayed the negative effects of high N on rice yield formation.
- Intervention effect RTNM under the SPAD threshold value 40 gave the highest rice yield.
- Intervention effect SSNM gave the highest nitrogen agronomic efficiency in rice.
- Intervention effect SSNM led to higher rice yield.
- Intervention effect SSNM decreased the infestation of sheath blight disease in rice.
- Recommendation SSNM and RTNM could alleviate environmental pollution in rice production.
- Association Optimal N rate is associated with higher light interception rate, RUE and harvest index in rice.
