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. The plants of four rice varieties (PD 6, PD 16, NDR 359, PS 5) were harvested after 30, 60, 90 and 120 days after transplanting and roots were also retrieved from the soil. Plant parts were separated, dried and weighed at each stage. The data was analyzed under three factorial completely randomized design. The main effects of type of plant parts, Zn level and varieties influenced the dry matter yield of rice plants significantly at 30 days after transplanting. The main effect of plant parts had statistically significant effect on the average dry matter yield of different plant parts of rice at 60 days after transplanting. The main effect of type of plant parts and variety affected the average dry matter yield of rice plants significantly at 90 days after transplanting. The main effect of plant parts, Zn levels and varieties had statistically significant effect on dry matter yield of rice plants at 120 days of transplanting.
