The concentrations of the above mentioned micronutrients
and heavy metals in the plants did not differ significantly because
of micronutrient spraying. Although not significant,
plants sprayed with Mn and Zn had, in most cases, the lowest
concentrations of all measured micronutrients and heavy
metals, whereas the plants sprayed with tap water exhibited
the greatest concentrations of micronutrients and heavy metals,
except for Mn and Zn. Concentrations of Zn and Mn
were drastically higher in the plants that received Zn or
Mn as foliar applications. Ni and Pb were not detected in
plant tissues.
There was no significant interaction between irrigation
water sources and micronutrient foliar spray treatment in all
measured micronutrients and heavy metals except for Mn
and Zn (Table 7). Accordingly, the concentrations of Mn
and Zn in plants irrigated with well water increased by higher
