PENGARUH VERMIKOMPOS DAN PUPUK ORGANIK CAIR TERHADAP K, Ca, Mg, Na TANAH SERTA PERTUMBUHAN LADA PERDU (Piper albi L.) PADA SISTEM PERTANIAN TERAPUNG

Shrub pepper is one of the commodities export crops that has high economic value. This aims of this study were to determine the effect of vermicompost and liquid organic fertilizer on K, Ca, Mg, Na soil and Mg of the plant also the growth of shrub pepper in floating agricultural systems. This study was conducted in November 2020 up to Januari 2021 in The Pool and Chemistry, Biology and Soil Fertility Laboratory, Soil science Department, Faculty of Agriculture, Sriwijaya University. This study used a Randomized block Design Factorial, which contained 10 treatments consisting of 2 factors with 3 replications. The first factor is the vermicompost, which consists of 5 levels, V0 (0 g plant-1), V1 (250 g plant-1), V2 (500 g plant-1), V3 (750 g plant-1) and V4 (1000 g plant-1). The second factor is a liquid organic fertilizer which consists of 2 levels, P1 (0 ml plant-1) and P2 (50 ml plant-1). The results showed that the treatment of vermicompost significantly affected Ca, Mg of soil and Mg of plant and liquid organic fertilizer treatment significantly affected Mg of plant. There is an interaction between vermicompost and liquid organic fertilizer treatment Mg of plant. The combination of 1000 g plant1 vermicompost and 50 ml plant-1 liquid organic fertilizer gave the best response to the K, Ca, Mg, Na of soil and Mg of plant, also to the enchancement of shrub pepper height in floating agricultural systems.
