Chloride, S, Ca, Na and Mg increased, whereas, P, K and Zn decreased in different plant parts with increasing level of Eciw. Increasing proportion of chloride increased chloride, Ca and Zn and decreased S, P, Na, K and Mg content in different parts of plant. Leaf contained maximum amount of all ions except Na which accumulated more in roots. After leaf, root contains more amount of CI, K, Mg and Na, whereas Ca and Zn were more in scion. The P and S content were almost same in all parts except leaf. The chloride and Ca increased with leaf age (except in rainy season where it decreased), whereas S, P, K and Zn decreased. The Na and Mg were more stable (1–5 months) followed by S and Ca, whereas chloride, K and Zn were stable for short period, i.e. during fifth to seventh months of leaf age. Leaf was the best tissue to diagnose toxicity and deficiency of nutrients in ber. Although chloride content was stable for a short period, i.e. during fifth to seventh month of leaf age, the best time for leaf sample to recognize its toxicity was first to third month of leaf age.
