Other claims from this paper (12)
- Observation Sugarcane response to applied nitrogen was highly variable across trials.
- Association Sugarcane nitrogen use efficiency was influenced by season, rainfall, soil, variety, irrigation and nitrogen application practices.
- Method / resource A soil specific nitrogen fertilizer recommendation system was developed for sugarcane agroclimatic zones.
- Method / resource NIRS was pioneered as a rapid advisory measure of soil organic matter and nitrogen mineralization potential for sugarcane.
- Method / resource A laboratory test was developed to predict ammonia volatilization losses from surface-applied urea fertilizer in sugarcane management.
- Method / resource Sugarcane varieties were classified into three nitrogen use efficiency categories affecting nitrogen recommendations.
- Method / resource Leaf and stalk nitrogen to silicon ratio was used to predict stalk borer damage risk in sugarcane.
- Method / resource A Fourier function supplied leaf nitrogen thresholds for sugarcane diagnosis.
- Method / resource DRIS was used for more accurate diagnosis of sugarcane nitrogen status.
- Observation Grower adoption of research outcomes improved sugarcane fertilizer nitrogen use efficiency from 2.0 to about 1.45 kg N per tonne cane.
- Observation Average sugarcane yields were not compromised during improved nitrogen efficiency.
- Observation Irrigated areas achieved about 28% improvement in sugarcane nitrogen fertilizer use efficiency.
