A field study was laidout to assess the impact of soil applied zinc on the yield of wheat varieties at student’s experimental farm, Department of Agronomy, Sindh Agriculture University Tando jam during the year 2015-16, was laidout in three replicated randomized complete block design (factorial) having net plot size of 9 m2. The treatments were five zinc levels i.e (0 kg ha-1 (control), 1 kg ha-1,1.5 kg ha-1, 2 kg ha-1 and 2.5 kg ha-1) and two wheat varieties (Sehar and Abdul Sattar). The observations were recorded on important growth and yield contributing characters viz: germination (%) m2, no of tillers m-2, plant height (cm), spike length (cm), spikelets spike-1, grains spike-1, Seed index (1000 grains wt,g) and Grains yield (kg ha-1). The result of the study indicated that all the growth and yield traits were significantly (P < 0.05) affected by zinc levels. It was observed that wheat crop delivery 2.5 kg ha-1, zinc result in 82.60 (%) germination, numbers of tillers 356 m-2, 102 cm plant height, 11.40 cm spike length, 27 spikelets spike-1, 81 grains spike, 41 g seed index, 6104 kg ha-1 grains yield. In the same way, the wheat receving 1 kg ha-1 zinc result in 80.40 (%) germination, numbers of tillers 256 m-2, 73.30 cm plant height, 7.40 cm spike length, 19 spikelets spike-1, 57 grains spike, 26 g seed index, 3230 kg ha-1 grains yield. These parameters are lowest except control. However, the interaction among the wheat variety the best response Sehar in germination 80.88 (%), numbers of tillers 291 m-2, plant height 81.81 cm, spike length 8.28 cm, spikelets spike-1 22.20, grains spike 66.60, seed index 31.20 g, grain yield 4131.20 kg ha-1. Such as the wheat variety Abdul Sattar were showed 80.51 (%) germination, numbers of tillers 272.20 m-2, 80.24 cm plant height, 8.06 cm spike length, 20.40 spikelets spike-1, 61.20 grains spike, 29.80 g seed index, 3682.20 kg ha-1 grain yield. It was proved from the research work that Sehar variety produced high performance than that of wheat variety abdul sattar.
