| Abstract: | Regular procedures for the establishment of norms for Diagnosis and Recommendation Intergrated System (DRIS) were adopted to compare foliar nutrient contents of N, P, K, Ca and Mg as well as nutrient ratio or product between every two elements in high-yield populations with that in low-yield populations. N/P, N/K, N/Ca, N/Mg, K/P, Ca/P, P/Mg, K/Ca, K/Mg and Ca/Mg were screened out for the DRIS parameters. and DRIS norms for foliar nutrient diagnosis of mango (Mangifera indica L. cv. Zihua) were put forward. |
