N2 - Among the major classes of plant hormones, auxins, gibberellins, and cytokinins are widely used for plant propagation. These hormones influence the physiological and developmental processes of plants such as root initiation, apical dominance, seed germination, leaf expansion, and development of buds, flowers, and fruits. Its exogenous application was found to significantly improve the growth of several important plants. This study aimed to determine the effectiveness of plant growth regulators (PGRs) derived from naturally occurring plant growth-promoting bacteria (PGPBs) in the production and propagation of selected crops. In this study, indole3-acetic acid (IAA) and gibberellic acid (GA) were extracted from naturally occurring PGPB Bacillus sp. The extracted hormone was nanoformulated for controlled release and increased uptake in plants. The nanoformulated hormones were applied in the propagation of coffee and the production of eggplant and ornamentals. Results showed that the application of nanoformulated IAA (Nano-IAA) significantly increased the survival rate of coffee compared to the commercially available auxin. Nano-IAA increased the germination rate of eggplant in acidic soil and root emergence of Bougainvillea over the negative control (water) but was comparable to that of the commercially available auxin. The nanoformulated GAs and commercially available GA increased the plant height and weight of asters compared to the control. The study showed the effectiveness of Nano-IAA and GA in the production and propagation of coffee, eggplant, and selected ornamentals. Hence, these nanoformulated PGRs can be a substitute for synthetic and imported IAA and GA in plant production and propagation.
