SKRIPSI PENGARUH PERSENTASE CAHAYA TERHADAP PERTUMBUHAN AWAL BIBIT TANAMAN KAKAO (Theobromu cacao L.)
ABSTRACT
The experiment about "CENTAGE ON THE EARLY GROWTH OF CACAO SEEDLING (Theobroma cacao L.)", had been caried out on the fifth of September, 1990 until the fifth of December, 1990, at Giriwarno, Kaliangkrik, Magelang District, Central of Java Province.
At a media of soil, sand and stable manare mixture with a ratio of 2: 1: 1. On altitude of 700 meter sea level.

The design was use Randomized Complete Block Design (ROHD), six (6) reslication and four (4) treatments
L1: 25% light
L2: 50% light
L3: 75% light
L4: 100% light
