Abstract:

A pot experiment was conducted in the green house of GB Pant University of Agriculture and Technology Pantnagar, to study the percent distribution of Zn on plant parts of four wheat varieties (UP 262, UP 2628. PBW 175 and UP2554) having varying Zn sensitivity at different growth stages. The soil used for pot experiment 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. The pretreatment imposed consisted of a factorial combination of four wheat varieties and two Zn levels (0 and 10 mg Zn kg-1 soil). There were two replications. Zinc was applied through a stock solution of Zn.SO4.7H2O. Among the growth stages, the maximum average total uptake of Zn was noted at D3 (85.4 µg/plant) followed by D4 (78.1 µg/plant) D2 (35.6 µg/plant) and D1 (10.6 µg/plant). Application of 10 mg Zn kg-1 soil increased the total average uptake of Zn per plant of wheat significantly by 31.4 percent over no application of Zn. At harvesting, the highest percent accumulation of Zn was noted in straw (55.9 %) followed by grain (32.0 %) and root (12.1 %). Among all four varieties UP 262 and PBW 175 stored more of the Zn in non-edible parts of the plant whereas higher amount of Zn was recorded in the grain of UP 2628 and UP 2554).
