Growth Performance of <i>Tetrapleura Tetraptera</i> (Schum and Thonn) Seedlings to Green Manure and Inorganic Fertilizer

Abstract

The use, types and method of fertilizers for agricultural and forest plants should be sustainable, ecofriendly and natural to the environment. Application of green manure is being used nowadays for soil nutrient management, growth and plant yields because of their natural effects. This study investigated the use of green manure andinorganic
fertilizer on the growth performance of Tetrapleura tetraptera. Topsoil, leucaenana leucoephala (leave powder) and inorganic fertilizer (NPK 15: 15:15) were used. The fertilizer were weighed and applied to the 5kg of soils at 0g, 10g and 20g each and were replicated six times. Growth parameters such as seedling heights, number of leaf and stem diameter were assessed weekly for aperiod of three months. The application leucaenana leucoephala’s leave powder as green manure showed significantly high effects on the growth parametersof Tetrapleura tetraptera seedlings at p ≤ 0.05. This study has shown the efficacy of leucaenana leucoephala’s leave powder as green manure for optimum growth of Tetrapleura tetraptera seedlings.
