Other claims from this paper (8)
- Association Cotton leaf nitrogen, potassium and phosphorus contents increased with nitrogen rate.
- Intervention effect Nutrient sources increased cotton leaf nitrogen concentration.
- Association Cotton nitrogen uptake increased with nitrogen application rate.
- Observation At 300 kg N ha-1, cotton nitrogen uptake decreased.
- Association Agronomic, internal use and recovery nitrogen efficiencies declined as nitrogen rate increased.
- Observation NPK-treated plots had the highest cotton nitrogen uptake, recovery efficiency and agronomic efficiency.
- Observation Poultry manure plots had maximum cotton internal and physiological nitrogen use efficiencies.
- Recommendation The authors recommend 150 kg/ha nitrogen from poultry manure or NPK for optimum nitrogen use efficiency in the study area.
