KAJIAN DISTRIBUSI BAHAN KERING PADA 10 KLON UNGGUL UBI KAYU (Manihot esculenta Crantz) UNTUK DETEKSI SIFAT FISIOLOGI DI KEBUN PERCOBAAN TAMAN BOGO, PURBOLINGGO, LAMPUNG TIMUR

Abstract

The objective of this study was to determine the distribution pattern of dry matter from
leaves to tubers in 10 cassava clones in two different land conditions (non-marginal and
marginal). The experiment was arranged in a factorial randomized block design (RBD)
(2x10), with three replications, resulting in 60 experimental units. The variables observed
included plant height, stem diameter, number of green leaves, fresh and dry weight of
leaves, stems, and tubers. The results showed that clones such as Cino, Soponyono,
Sekoci, Vamas-1, and Garuda tended to show a more dominant distribution of dry matter
to tubers, indicated by relatively high dry weight of tubers and tuber diameter. In contrast,
clones KM and Waxy showed a tendency for a more dominant distribution of dry matter to
vegetative growth, as seen from the low dry weight of tubers at 10 months after planting
(BST). Clones UJ3 and UJ5 showed a relatively balanced distribution pattern between
vegetative organs and tubers. Thus, there are differences in dry matter distribution
patterns between cassava clones in different land conditions.
