Effect of biopriming on seed germination, growth and biomass of waras (Heterophragma quadriloculare Roxb.)

Present investigation was undertaken during the year 2019-2020 at College of Forestry, Navsari Agricultural University, Navsari, Gujarat, India to ascertain effect of biopriming on seed germination, growth and biomass Heterophragma quadriloculare. The seed priming treatments comprised of application of Azotobactor, Potassium Mobilizing Bacteria: Pseudomonas Trichoderma 2 %, alone and in combination. Germination (%), survival (%), mean daily germination, peak value and germination value were not significantly influenced by different biopriming treatments. Significantly maximum plant height (30.18 cm), collar diameter (8.10 mm), number of leaves (28.46), fresh root weight (29.93 g plant^-1), dry root weight (9.85 g plant^-1), fresh shoot weight (24.45 g plant^-1) and dry shoot weight (10.12 g plant^-1)in response to with application of Azotobactor + KMB + PSB + Pseudomonas + Trichoderma 2 % (0.4 % Each)] followed by Azotobactor + PSB + KMB 2 % (0.66 % Each)] and the minimum was in control.
