Khaya senegalensis (African Mahogany) is one of plantation species growing in Indian condition. A study was undertaken to evaluate organic based potting mixtures for early growth and biomass in Khaya senegalensis. Total ten potting mixture combinations were prepared using different organic materials such as Coco peat, Rice husk, Perlite, Vermiculite, FYM, Castor Cake, Neem Cake, Sugarcane press mud and Vermicompost with Red Soil. Among 10 treatments, T9 i.e., potting mixture composition of vermicompost and red soil in the ratio of 1:1, resulted in maximum seedling growth in terms of height, collar diameter, root length, number of leaves and seedling biomass at 120 days after sowing, followed by T5 (Sand: Red soil: FYM of 1:1:1) and T7 (Neem cake: Red soil of 1:1 ratio) in Khaya senegalensis. Therefore, treatment T9 is suggested to use in the nursery for raising large scale seedling production of Khaya senegalensis.
