Other claims from this paper (16)
- Intervention effect Omitting N significantly reduced wheat yield and yield-related traits across all sites.
- Observation P limitation was significant in 50% of the locations.
- Observation The average wheat yield response to N application was 2071.9 kg ha -1, ranging from 847.2 to 2873.6 kg ha -1.
- Observation The mean wheat yield response to P was 499.1 kg ha -1, ranging from 16.6 to 850.8 kg ha -1.
- Observation Soil indigenous nutrient supply was only 45.0% sufficient for N.
- Observation Soil indigenous nutrient supply sufficiency was higher for P, at 87.0%.
- Observation Potassium, sulfur and zinc were non-limiting, with soil supplies exceeding 90%.
- Observation Boron was non-limiting, with soil supplies exceeding 90%.
- Observation Yield gaps due to N omission averaged 53.9%.
- Observation Yield gaps due to P omission averaged 11.9%.
- Intervention effect Omitting K, S, Zn and B had negligible effects on yield gaps.
- Observation Agronomic efficiency for N was 13.1 kg kg -1, below that for P.
- Observation Agronomic efficiency for K was 5.2 kg kg -1, below that for P and N.
- Observation N is the primary yield-limiting nutrient in the study area, with P secondary in half of the evaluated farms.
- Recommendation Site-specific fertilizer recommendations emphasizing optimized N and P application are critical to enhance wheat productivity and minimize yield gaps.
- Recommendation Multi-year experiments are recommended to address season variation in the effect of nutrient omission treatments.
