Abstract
The chemical diagnosis of nutritional status of Bael (Aegle marmelos Correa) tree by leaf analysis was done to study the effect of leaf age and leaf position on foliar nutrient composition of Bael. The results showed that leaf age has significant influence on leaf mineral content, whereas the position of leaf on shoot did not have any significant effect. Interactions between leaf age and position were found to be significant for nitrogen, boron and iron content. In general, stability in level of nitrogen (N), phosphorus (P), and potassium (K) contents was observed in November–December (6‐ to 7‐month‐old leaves) and calcium (Ca) and magnesium (Mg) showed their stability in 2‐to 3‐month‐old leaves (July–August). The contents of boron (B), manganese (Mn), copper (Cu), and zinc (Zn) were found stabilized in September–October (3‐ to 4‐month‐old leaves), indicating their suitability for sampling in Bael.
