Pengaruh Inokulasi Mikoriza Arbuskular dan Pupuk Kandang Sapi terhadap Pertumbuhan Semai Kayu Putih (Melaleuca Cajuputi) di Tanah Pasca Tambang Batu Kapur

Abstract

Post-mining soil has low fertility so that the revegetation process will be hampered. The addition of soil ameliorants and proper plant selection are necessary for successful revegetation. The use of Arbuscular Mycorrhizal Fungi (AMF) and cow manure is expected to help plant growth on post-limestone mining soil. The aims of this study were (1) to analyze the interaction effect of AMF and cow manure on the growth of eucalyptus plants in post-lime mining soil, (2) to analyze the optimal dose of manure in increasing eucalyptus growth. This study used a completely randomized design (CRD) with two treatment factors (mycorrhizae and cow manure). The results showed that there was no effect of the interaction between AMF inoculation with cow manure. Giving AMF alone also did not significantly affect the growth of eucalyptus seedlings. While the single factor of cow manure had a significant effect on seedling growth, the best dose of cow manure was 15% which could increase growth in height and diameter by 28,04% and 38,41%, respectively, compared to control plants.
