Other claims from this paper (7)
- Intervention effect Reducing first nitrogen application reduced nitrogen loads in all cropping seasons.
- Intervention effect The 195 kg ha−1 N treatment gave slightly lower sugarcane yields than 230 kg ha−1 N in seasons one and three.
- Intervention effect Nitrogen uptake was almost the same under the conventional and reduced first fertilizer treatments in seasons one and three.
- Intervention effect Zero nitrogen in the first fertilization would substantially reduce sugarcane yield in all seasons.
- Intervention effect Replacing the conventional first application with T2 improved nitrogen recovery by 9.7–11.9%.
- Intervention effect Replacing the conventional first application with T2 reduced nitrogen leaching by 13 kg ha−1.
- Recommendation The authors considered T2 a feasible fertilization practice for farmers.
