To assess the impact of artificial leaf defoliation of Populus deltoides on its different growth parameters, a study was conducted on G-48 clone under field condition and four defoliation treatments, i.e. 25%, 50%, 75% and 100%, were done in addition to control. Defoliation pattern was simulated with insect defoliator Clostera spp. feeding and the experiment was conducted from July to December. Significant variation was observed in tree height and DBH growth loss in all the treatments with respect to control, and 24.16–66.03% volume increment loss was observed under 25–100% leaf defoliation respectively
