Wheat is a common food and is widely consumed by people all over Pakistan. Water adds more than 70% to the structure of the plant body and is important for all anabolic and catabolic processes. Abiotic stress is a foremost limitation that affects the growth and yield of wheat crops. Therefore, the objective of this study was to evaluate the effects of the foliar appliance of indole acetic acid on wheat yield components. For this purpose, an experimental trial was conducted during the winter season of 2021 (first week of December 2021) with different concentrations of indole acetic acid 0 ppm, 200 ppm, and 400 ppm. Maximum concentration of indole acetic acid 400ppm resulted maximum in plant height was (106.77 cm), number of tiller (346.22), number of spikelet’s spike-1 (17.11), number of grains spike-1 (55.44), 1000 grain weight (39.19 g), grain yield (5.32 t/ha), biological yield (10.646 t/ha), harvesting index was (37.804%) were obtained respectively. It is determined that irrigations and the application of various levels of indole acetic acid have a favorable impact on grain yield and yield components. Indole acetic acid proven to be a beneficial application.
