The leaf nutritional status of mango orchards was assessed using diagnosis
and recommendation integrated system (DRIS). The DRIS norms, which
showed higher variance and lower coefficients of variation, are found to
have greater diagnostic precision. As per DRIS indices, a relative deficiency
for magnesium, zinc, and boron corresponding to relative sufficiency for
calcium, nitrogen, phosphorus, sulfur, and potassium was detected in 9-
year-old mango orchards. For the younger orchards (6–7 year old), the
order of requirement of nutrients was found to be calcium > sulfur >
potassium > boron > nitrogen > phosphorus > magnesium > zinc. Boron
was found as the most yield-limiting elements in all age group of plants.
When the DRIS indices were compared on the basis of soil pH, calcium and
magnesium were most yield-limiting nutrients below pH 5.5, while nitrogen,
zinc, and boron were found to be most limiting above pH 5.5.
