Accumulation of essential nutrients by various cultivars of mango (Mangifera indica L.) during different growth stages

Estimation of elemental nutrient content in mango fruits at different fruit growth stages in very important to understand the availability and uptake nutrient balance in the source-sink nutrient pool in the plant physiology. For conducting this experiment fruit of mango variety viz., Kesar, Alphonso, Sonpari and Totapuri were collected at different stages like Marble, egg and Harvest for estimation of macronutrients (N, P, K, Ca, Mg and S) and micronutrients (Zn, Fe, Mn and Cu). In the present investigation it can be concluded that highest accumulation of N (1.72%) and Mg (1.08%) was recorded at marble stage while, Cu (49.89 ppm) at harvest stage in the Sonpari variety. The maximum Fe (120.53 ppm) and Mn (17.87 ppm) were in Totapuri variety at egg and marble stage, respectively. whereas Zn (45.05 ppm) accumulation was increase in the same variety but, at marble stage. However, higher P (0.31%) and S (0.55%) gathering was reported in Alphonso variety while, K (1.57%) and Ca (0.70%) in Kesar at egg stage.
