ABSTRACT
Poor physical properties and limited amount of available nutrients wereregarded as two main constraints possessed by coastal sandy soil for agricultural production. The objective of thestudy was to identify the effect of green manure and clay soil applications toward soils characteristic, growth andyield of peanut (Arachis hypogeae L.) in the coastal sand soil. A completely randomized design with factorialpattern 4 x 5 was applied in this experiment. The first factors were the rate of green manure application consisted offour levels, i.e. control, 5 Mg ha-1, 10 Mg ha-1 and 15 Mg ha-1 of green manures. The second factors were the additionof five different levels of clay, i.e. control, Vertisol, Alfisol, Inceptisol and Vertisol + Alfisol + Inceptisol. Eachtreatment combinations were replicated three times. Results of the study showed that the vertisol soil affectingphysical characteristics of soil. The addition of Inceptisol soil affected chemical characteristic of soil, increasedgrowth and yield of peanut. Application of 15 Mg ha-1 of green manures affected toward the characteristic of soilsexcept of the crop yields. However, there was no significant interaction effect from both materials to all variablesobserved.
