Abstract

This research had been conducted at experimental field of UPT Balai Benih Induk Palawija Tanjung
Selamat, North Sumatra land in October 2016 until January 2017, using factorial randomized block
design with two factor, dose of compost cacao fertilizer (0, 113, 225, and 338 gram per polybag)
and dose of NPK fertilizer (0 ,4, 8, and 12 gram per polybag). Parameter observed were plant
height, stem diameter, number of leaf, summarize of leaf area, fresh weight of shoot, dry weight of
shoot, fresh weight of root, dry weight of root and shot root ratio. The result showed response of
granting compost cacao fertilizer on cacao seed significantly effect to plant height, number of leaf,
stem diameter, and dry weight of shoot. Response of NPK fertilizer cacao seed significantly effect
to fresh weight of shoot, and dry weight of shoot. Interaction between granting compost cacao
fertilizer and NPK fertilizer significantly effect to stem diameter, dry weight of shoot, and
summarize of leaf area parameter.

Penelitian dilaksanakan di lahan balai UPT. Balai Benih Induk Palawija Tanjung Selamat, Sumatera Utara pada Oktober 2016 – Januari 2017, menggunakan rancangan acak kelompok faktorial dengan dua faktor yaitu pemberian dosis kompos kulit buah kakao (0, 113, 225, 338 g/polibag) dan dosis pupuk NPK (0, 4, 8, 12 g/polibag). Parameter yang diamati adalah tinggi bibit kakao, diameter batang bibit kakao, jumlah daun bibit kakao, total luas daun bibit kakao, bobot basah tajuk bibit kakao, bobot kering tajuk bibit kakao, bobot basah akar bibit kakao, bobot kering akar bibit kakao, rasio bobot kering tajuk – akar bibit kakao.Hasil penelitian menunjukkan bahwa perlakuan pemberian kompos kulit buah kakao berpengaruh nyata terhadap parameter tinggi tanaman, jumlah daun, diameter batang dan bobot kering tajuk. Pada perlakuan pemberian pupuk NPK berpengaruh nyata terhadap parameter bobot basah tajuk dan bobot kering tajuk. Interaksi antara kedua perlakuan berpengaruh nyata terhadap parameter diameter batang, bobot kering tajuk, dan total luas daun.
