Application of Sludge and Manure on Subsoils as Medium of Palm Oil Seedling (Elaeis guineensis Jacq)

Basyaruddin Basyaruddin

Abstract


An experiment to study the effect of sludge and manure application and their interaction on the response of palm oil seedling in main nursery, physical and chemical properties of subsoil has been conducted. The experiment was carried out in experimental farm of Agricultural Faculty,UISU,located at Medan Johor District in elevation at 45 m above sea level. The research design is Factorial Randomized Block Design. Treatments tested is consisting of 4 levels of sludge application namely 0% (0 kg /polybag), 5% (0.5 kg/polybag), 10% (1 kg/polybag), and 15% (1.5 kg/polybag) and 4 levels of manure applicationnamely 0% (0 kg /polybag), 5% (0.5 kg/polybag), 10% (1 kg/polybag) and 15% (1.5 kg/polybag).Variables observed are root fresh weight and root dry weight as well as some soil properties such as water holding capacity, C-organic, total N, C/N ratio, soil pH, and Cation Exchange Capacity (CEC). The results shows that the application of sludge was significantly affect on C-organic, total N, and CEC, and water holding capacity. The sludge application also significantly increases the root dry and fresh weight. Meanwhile the application of manure significantly increase water holding capacity (WHC), organic C (C), pH, cation exchange capacity (CEC). The growth of palm oil seedling significantly increases as indicated by the increase of root dry and fresh weight. Good medium of palm oil seedling were obtained in composition consisting of 1.5 kg sludge/polybag and 1.5 kg manure/polybag mixed with subsoil material.
