Abstract: Tobacco is a botanical species that yields goods of a refined and elaborate character. The quality level is contingent upon the individual preferences of each purchaser. Tobacco is a distinctive and gratifying commodity that lacks a universal accepted worldwide standard, unlike other agricultural goods. One significant determinant influencing tobacco plants throughout the cultivation phase of the crops. The incorporation of growth regulators in the manufacturing process is a factor that warrants consideration. Auxin is a ubiquitous hormone synthesised in plant tissues during periods of active division. Auxin plays a crucial part in the cellular processes of division, expansion, and specialisation. Auxin type IAA has emerged as a viable choice for application. The present study used a fully randomised design, including four treatment levels: 0, 100ppm, 200ppm, and 300ppm IAA concentration. The measurements under investigation in this study encompass leaf width, leaf length, fresh weight, and overall crop yield at the time of harvest. Analysis of the harvest findings at 60 days after planting (DAP) and 75 DAP reveals variations in leaf width and leaf length. However, no differences are detected at 90 DAP. There were no significant differences seen in the fresh weight and overall yield of the crops in terms of total leaf weight and plant weight.
