Abstract

Liquid organic fertilizer (LOF) gains great attention recently for its practical preparation, use and environmental value. Many agricultural waste may be used as raw material, thus in turn may contribute to cleaner and safer agriculture practice. This research aims to compare various sources of agricultural waste applied with two dosages for improving rubber latex production. A field experiment was conducted in Payaramen Timur of Ogan Ilir Regency in South Sumatra using a split design comprising five LOF as main plot (P1 pineapple and watermelon; P2 watermelon; P3 pineapple peel; P4 lemon fruit; P5 cabbage and brassica) and two dosages of application weekly (40 and 50 ml/L). Thirty treeas were used as samples. Latex was collected weekly. Initial results before LOF application indicate a great variation in weekly latex production (12 to 260 gram per tree). After one week average latex production remains low or high being consistent with the initial values. Several tress indicate a sharp increase in latex production being the best by fruit waste compared with vegetable source. The final production may reach 100 to 200 gram per tree weekly. With this limited time of measurement, LOF demonstrates a potential use as provisional source of fertilizer for rubber plantation.
