Other claims from this paper (15)
- Association LAI of wheat increased with increasing irrigation and nitrogen levels.
- Observation fIPAR followed a trend similar to LAI.
- Observation LAI and fIPAR showed a logarithmic relationship with R 2 values of 0.92 and 0.93 in the two years.
- Observation The radiation extinction coefficient varied between 0.41 and 0.78.
- Association The extinction coefficient was significantly affected by nitrogen levels.
- Association The extinction coefficient was not influenced by irrigation levels.
- Intervention effect Grain and above-ground biomass yields were not significantly affected by irrigation levels.
- Intervention effect Application of 160 kg N ha −1 gave 12–33% higher grain yield than 40 kg N ha −1.
- Intervention effect Application of 160 kg N ha −1 gave 22–25% higher AGB than 40 kg N ha −1.
- Intervention effect N160 increased TIPAR by 9–20% compared with N40.
- Observation TIPAR explained 83–86% of the variation in AGB yield of wheat.
- Intervention effect Three irrigations gave 6% and 18% higher RUE than five and two irrigations in 2013–2014.
- Intervention effect Irrigation had no significant effect on RUE in 2014–2015.
- Intervention effect N160 gave 5–13% higher RUE than N40.
- Recommendation Wheat grown with three irrigations and 160 kg N ha −1 can achieve higher RUE without significant AGB reduction compared with five irrigations.
