Abstract

Influence on the growth of Rhizopora apiculata seedlings given fertilizer Beauveria, Mycorrhiza, Trichoderma or not given fertilizer. Mangrove forests are the main ecosystem supporting life activities in coastal areas and play an important role in maintaining the balance of biological cycles in the environment. The purpose of this study was to determine the effect of Beauveria fertilizer, Trichoderma fertilizer, mycorrhizal fertilizer and not given fertilizer on the growth of Rhizophora apiculata seedlings. This study used a complete randomized design (RAL) consisting of 4 treatments with 10 repetitions. The treatment was carried out with P0 = control, P1 = Beauveria, P2 = Trichoderma, P3 = Mycorrhiza. From the data of observation of seedling height, seedling diameter, it can be concluded that the effect of fertilizer does not affect plant growth and can be declared insignificant.
