<![CDATA[ABSTRAK: Pembibitan tanaman menjadi salah satu faktor penting yang harus di perhatikan dalam membudidayakan tanaman kopi. Pemberian kompos johar dapat membantu mencukupi kebutuhan unsur hara yang diperlukan tanaman. Penelitian ini bertujuan untuk mengetahui respon pertumbuhan bibit kopi arabika pada tanah inceptisol. Aplikasi berbagai dosis kompos johar (0, 9, 11, 13 dan 15 g/tanaman) diatur menurut rancangan acak kelompok (RAK) dan diulang empat kali, telah dilaksanakan di Desa Lape Kecamatan Poso Pesisir pada bulan Februari sampai Juli 2023. Hasil penelitian menunjukkan bahwa aplikasi kompos johar berpengaruh nyata terhadap lilit batang umur 6, 8, 10 dan 12 minggu setelah tanam (MST), berat kering akar dan panjang akar, berpengaruh sangat nyata terhadap tinggi tanaman umur 14 dan 16 MST, lilit batang umur 14 dan 16 MST serta bobot basah tajuk, tetapi berpengaruh tidak nyata terhadap waktu berkecambah, jumlah daun, bobot kering tajuk dan laju pertumbuhan relatif. Aplikasi kompos johar 13 g/tanaman memberikan pertumbuhan bibit yang lebih baik dan berbeda nyata dengan tanpa aplikasi kompos (kontrol). ABSTRACT: Plant nursery is one of the important factors that must be considered in cultivating coffee plants. The provision of johar compost can help meet the nutrient needs of plants. This study aims to determine the growth response of Arabica coffee seedlings on inceptisol soil. The application of various doses of johar compost (0, 9, 11, 13 and 15 g/plant) arranged according to a randomized block design (RAK) and repeated four times, has been carried out in Lape Village, Poso Pesisir District from February to July 2023. The results showed that the application of johar compost had a significant effect on stem circumference at ages 6, 8, 10 and 12 weeks after planting (WAP), root dry weight and root length, had a very significant effect on plant height at ages 14 and 16 WAP, stem circumference at ages 14 and 16 WAP and wet weight of the crown, but had no significant effect on germination time, number of leaves, dry weight of the crown and relative growth rate. Application of 13 g/plant of Johar compost provided better seedling growth and was significantly different from no compost application (control). ]]>
