Pengaruh Penggunaan Berbagai Jenis Pupuk Kandang terhadap Pertumbuhan Bibit Rhizophora apiculata di Dusun II, Desa Pulau Sembilan, Pangkalan Susu, Sumatera Utara.

Abstract

Massive Degradation of mangroves require restoration efforts to restore the function of the mangrove ecosystem. Restoration is necessary to improve the potential of the mangrove ecosystem. The type of mangrove that can be developed in ecosystem restoration efforts is Rhizophora, especially R. apiculata. Mangrove fertilization plays an important role in supporting mangrove ecosystem restoration efforts. The purpose of this study was to determine the effect of applying cow manure, goat manure, chicken manure, and quail manure and without manure on the growth of Rhizophora apiculata mangrove seedlings. This study was conducted from October 2023 to January 2024. This study used a Completely Randomized Design consisting of 5 treatments and 5 replications, namely P0 (control/without fertilizer application), P1 (cow manure 200 g/seedling), P2 (goat manure 200 g/seedling), P3 (chicken manure 100 g/seedling), and P4 (quail manure 50 g/seedling). Observations and data collection were carried out every two weeks for 14 weeks. The parameters observed were seedling height growth, seedling diameter, number of leaves, seedling dry weight, seedling wet weight, leaf area, temperature, salinity, rainfall, air humidity and seedling growth rate. The results showed that the treatment that had the most effect on the growth of height, diameter, number of leaves, leaf area, wet weight and dry weight of R. apiculata seedlings was the provision of 100 g/seedling chicken manure.
