Abstract: A field experiment was conducted at a research farm, department of forestry, JNKVV, Jabalpur during the rabi season 2020-21 and 2021-22 to find out the growth of Gmelina trees at different fertilizer levels under agroforestry systems. The experiment was laid out in a factorial randomized block design (FRBD) with 4 replications and 2 factors and 3 fertilizer treatments consisting of F1 (75%NPK@ 45:30:30 kg ha-1), F2 (100%NPK@ 60:40:40 kg ha-1), and F3 (125%NPK@ 75:50:50 kg ha-1) the nutrient utilization have to influence the growth of Gmelina tree different fertilizer levels. The result revealed that the growth of dbh and height was found highest in F3 (8.04, 8.3 and 8.17 cm) and (3.84, 3.94 and 3.80 m) respectively, first, second year and pooled data. This parameter directly impacts on derived parameters like basal area and volume, thus maximum fertilizer levels found in basal area and volume in F3 (2.6, 2.75 and 2.67 m2 ha-1) and (10.8, 11.7 and 11.3 m3 ha-1) respectively in both year and pooled data.
