On-farm conservation of elite and indigenous mango germplasm is crucial from the
viewpoint of biodiversity conservation and its utilization for future use. Such conservation
contributes to breeding of new varieties, research on biotic and abiotic stress complexes,
evaluating nutrient dynamics in supporting their livelihood. One hundred thirty eight mango
germplasms conserved in the experimental farm of CISH, Rehmankhera, Lucknow over decades
were used for evaluating micronutrient status. The study revealed the lowest Zn content in Pan &
Aswania (11 mg kg-1) to the highest in Rousa (28 mg kg-1) across these 138 mango germplasms
while the corresponding values of Boron in Langra Digha (6.6 mg kg-1) and Husn-e-ara (44.8 mg
kg-1). It was further inferred that a range of 6 mg kg-1 (Modami Model) to 52 mg kg-1 (Anaiwara)
of Cu was estimated across these germplasms. In case of Mn and Fe micronutrients, wider
variations across these germplasms were recorded. The concentrations of Mn varied between 122
(Mithua Bihar) and 347 (Prabha Shankar) mg kg-1 and Fe being 101(Shohrab Shah) and
461(Bombay Green) mg kg-1. The distribution pattern indicated that highest percentage of B
(52.9%) was recorded in the range of 21–30 mg kg-1, 61.6% of Zn (11–20 mg kg-1), 45.7% of Cu
(16–30 mg kg-1), 68.1% Mn (101–200 mg kg-1) followed by 75.4% Fe (101–200 mg kg-1). Wider variations in micronutrients contents in some existing commercial mango cultivars were found and such variations in micronutrient contents indicated the differential response of mango germplasms under similar soil-climatic conditions for future nutrient management strategy
