ABSTRACT
A pot experiment was conducted in the green house of GB Pant University of Agriculture and Technology Pantnagar, to study the effect of Zn treatment on its concentration and dry matter yield in different plant parts of four wheat varieties. The soil had sandy loam texture, 7.2 pH, 0.9% organic carbon and 0.47 mg DTPA extractable Zn per kg soil. Each pot received recommended dose of 25 mg N, 11.2 mg P and 20.75 mg K kg-1 soil. Application of 10 mg Zn kg-1 soil significantly increased the average dry matter yield in plant parts. Among the varieties UP 262 recorded the highest average concentration of Zn per plant part at 30, 60 and 120 days after sowing. At the stage of harvesting the UP 2628 (1.135 g) reported the maximum average dry matter yield per plant and the lowest value was noted in UP 262 (0.844 g). The present study revealed that maximum accumulation of Zn took place in the stem at initial growth stages whereas; at later stages, higher amount was accumulated in root. The variety UP 2628 showed highest grain yield and lowest was recorded in UP262. The varieties PBW 175 and UP 2554 exhibited intermediate behaviour.
Key words: Zinc concentration, Wheat varieties, Plant parts, Dry matter yield.
