Pengaruh Metode Perbaikan Tanah Salin terhadap Serapan Nitrogen dan Fosfor Rumput Benggala (Panicum Maximum)

Abstract

The coastal area has a potential resource for livestock development. This is supported by large areas of marginal land that can be used for forage production. However, forage production in coastal areas is often limited by saline soil which has high sodium concentration. This study aimed to assess the effect of saline soil improvement methods on nitrogen and phosphorus uptake of Bengagala grass (Panicum maximum). The experiment was conducted for 5 months at the Greenhouse of Forage Science Laboratory, Department of Nutrition and Feed Science, Faculty of Animal Science and Agriculture, Diponegoro University. The experiment was arranged based on completely randomized Design (CRD) with 3 replications and 7 treatments (T0: Control; T1: gypsum (0.02 kg/pot), T2: rice husk ash (0.01 kg/pot); T3: animal manure (1.30 kg/pot); T4: gypsum (0.02 kg/pot) and rice husk ash (0.01 kg/pot), T5: gypsum (0.02 kg/pot) and animal manure (1.30 kg/pot); T6: rice husk ash (0.01 kg/pot) and animal manure (1.30 kg/pot). Parameters observed were (1) absorption of nitrogen, (2) absorption of phosphorus. The results showed that the treatment of gypsum and animal manure increased uptake of nitrogen and phosphorus in saline soil. It can be concluded that the treatment of gypsum and animal manure resulted in the highest nitrogen and phosphorus uptake by Benggala grass
