Other claims from this paper (19)
- Method / resource DRIS established nutrient-ratio reference norms from a high-yield rice population.
- Method / resource The rice DRIS sufficiency range for N was 1.49–2.50.
- Method / resource The rice DRIS sufficiency range for P was 0.14–0.23.
- Method / resource The rice DRIS sufficiency range for K was 0.57–1.11.
- Method / resource The rice DRIS sufficiency range for Ca was 0.30–0.58.
- Method / resource The rice DRIS sufficiency range for Mg was 0.13–0.30.
- Method / resource The rice DRIS sufficiency range for S was 0.14–0.26%.
- Method / resource The rice DRIS sufficiency limits for Fe were 64–217.
- Method / resource The rice DRIS sufficiency limits for Mn were 72–184.
- Method / resource The rice DRIS sufficiency limits for Zn were 15–24.
- Method / resource The rice DRIS sufficiency limits for Cu were 3–6 mg kg−1.
- Observation 1.78 of surveyed rice fields were low in P.
- Observation 11.20 of surveyed rice fields were low in K.
- Observation 0.76% of surveyed rice fields were low in S.
- Observation 1.53 of rice samples were low in Mn.
- Observation 2.04% of rice samples were low in Zn.
- Intervention effect Applying the DRIS-prioritized nutrients generally increased rice grain yield, except for Mn.
- Intervention effect CaCl2 or MgCl2 application did not increase rice grain yield at sites where those nutrients were most required.
- Recommendation DRIS diagnosis and application of most required nutrients was recommended to improve rice yield.
