The experiment was conducted during Rabi, 2023 to study the effect of foliar application of zinc on the growth and yield of sesame (Sesamum indicum L.) at Students’ Experimental Farm, Department of Agronomy, Faculty of Crop production, Sindh Agriculture University, Tandojam in a three replicated randomized complete block design (RCBD). The treatments included; T1 = Control (No zinc), T2 = 1.5% @ vegetative stage, T3 = 2.0% @ flowering stage and T4 = 2.0% @ pod formation. The results of the study indicated that the sesame treated with 2.0% @ pod formation (T4) resulted maximum 58.51 m-2 plant population, 168.00 cm plant height, 12.00 number of branches plant-1, 156.00 capsules plant-1, 49.42 seeds capsule-1, 46.00 g seed index and 847.05 kg ha-1 seed yield. The 2.0% @ flowering stage (T3) resulted 59.00 m-2 plant population, 144.62 cm plant height, 11.48 number of branches plant-1, 122.85 capsules plant-1, 43.58 seeds capsule-1, 41.91 g seed index and 720.85 kg ha-1 seed yield. Similarly, the sesame treated with 1.5% @ vegetative stage (T2) resulted 56.66 m-2 plant population, 121.42 cm plant height, 10.31 number of branches plant-1, 87.25 capsules plant-1, 37.39 seeds capsule-1, 37.82 g seed index and 595.64 kg ha-1 seed yield. However, control (No zinc) resulted minimum 56.73 m-2 plant population, 97.50 cm plant height, 9.14 number of branches plant-1, 51.69 capsules plant-1, 31.38 seeds capsule-1, 33.73 g seed index and 470.14 kg ha-1 seed yield. After going through the findings of the present research, it was concluded that the growth and yield of sesame increased simultaneously with increasing zinc levels and the sesame fertilized with Zn @ 5 kg ha-1 resulted in highest grain yield (836.32 kg ha-1), followed by Zn @ 4 kg ha-1 (830.47 kg ha-1) and Zn @ 3 kg ha-1 (824.68 kg ha-1).
