Abstract: Populus deltoides is grown on a significant scale in India and is an important plant species in the terms of economic and ecological value commonly known as Popular. It supports the socio-economic stability among the household in the irrigated plains of northern India. It grows at a very fast rate and consisting fine wood properties for paper making as well as a timber species important to increase the total forest cover outside the forest. Also, support a number of micro-organisms and other biodiversity in living as well as decaying stage of the life span. The present study was conducted to examine the vegetative propagation and effects of maturation in Populus deltoides and to find a suitable hormone for large-scale cultivation of Populus deltoids to proliferate the economy of Indian farmers. To achieve the following objectives, the stems were cut down and treated with different concentrations of the different Hormones which were further grown on the vermiculite medium and the effect of different hormones was examined. In this process, the rooting from the stem was observed and analyzed. The activity of hormones on the plant stem resulted in various inferences. The study revealed that Indole Butyric Acid (IBA) was most effective in plant growth than the other growth hormone such as Indole Acitic Acid and Gibberellic Acid, etc. It was also observed during the study that Indole Butyric Acid shows maximum leaves formation (55.63±6.4), sprouting (42.0±2) and average root height (10.20±9.0) at 1500 ppm concentration while increasing the concentration of IBA more than 1500 ppm, inhibit the plant growth rate in this plant species.
