Abstract : The leaf nutrient status of 30 bearing mango orchards was studied in relation to sand-culture-based critical limits already reported for 1-2 year old mango seedlings from India and Florida. Several orchards which could be rated as deficient by these criteria were found to be high yielding and free from deficiency symptoms. Year-to-year variation was significant for yield, P, Ca and S. Similarly, orchards differed significantly in respect to their N, P, K and S status.
