Other claims from this paper (11)
- Association Nitrogen fertilization and soil texture significantly affected all measured wheat traits.
- Association Nitrogen fertilization interacted with soil textural group for grain protein content, thousand kernel weight, test weight and chlorophyll meter readings.
- Observation Total wheat nitrogen uptake ranged from 39 to 96 kg N ha −1.
- Observation Wheat grain protein content ranged from 13 to 18 g kg −1.
- Intervention effect Total wheat nitrogen uptake rose in proportion to nitrogen fertilizer rate.
- Intervention effect Nitrogen rates above 120 kg N ha −1 did not increase total wheat yield, test weight or thousand kernel weight.
- Intervention effect Nitrogen rates above 120 kg N ha −1 did not increase wheat chlorophyll meter readings.
- Association Relative chlorophyll meter readings at flowering explained 87% of wheat grain yield variation.
- Association Relative chlorophyll meter readings at flowering explained 73% of wheat grain protein content variation.
- Intervention effect Splitting the recommended nitrogen rate between planting and tillering gave high total wheat yield and grain nitrogen uptake.
- Intervention effect Splitting the recommended nitrogen rate between planting and tillering gave the highest wheat grain protein content price premium.
