Abstract: The effects of Zn on growth and growth components of wheat were studied in sand culture using hydroponics solution. Five Zn treatments were given to wheat along with other essential nutrients. The plants were stunted in the control pots and weaker than the plants treated with Zn due to Zn deficiency. The growth of plants, supplied 20 μg Zn ml-1 was also lower than the other Zn-treated plants. Well-defined Zn deficiency symptoms were not observed in wheat plants however copper deficiency symptoms were obvious when Zn was applied at the higher rate for a longer time. Dry matter of wheat increased by increasing rates of Zn up to 15 μg ml-1. Above these optimum rates, the higher rates of Zn application depressed the dry weight of crop. The plants from the control pots had lower Zn concentrations, which ranged between 15-16 μg g-1. The data also revealed that Zn concentration in the second growth stage (S2) was lower compared to the first growth stage (S1) and the uptake of Zn by the plants was higher as dry matter yield was higher for stage S2.
