Pengaruh Pemberian Pupuk Npk Pada Media Tanam Yang Berbeda Terhadap Pertumbuhan Tanaman Kamboja Jepang (Adenium Sp.)
ABSTRACT
Japanese cambodia (Adenium sp.) is one of the horticultural commodities
of ornamental plant species whose beauty lies in the flowers, roots, and stems in
the form of humps. The purpose of this study was to determine the best dose of
NPK fertilizer and the composition of the appropriate growing media for the
growth of Japanese frangipani (Adenium sp.) plants. This research was carried
out in the experimental garden of the Faculty of Agriculture, Riau University,
Bina Widya Campus Km 12.5, Simpang Baru Village, Tampan Pekanbaru District
for seven months, from February-August 2019. The frangipani plant seeds used
were ±2 months old with NPK pearl fertilizer (16:16:16). The study was
conducted in a 4x3 factorial experiment using a randomized block design (RAK)
which consisted of 2 factors, so there were 12 treatment combinations. Factor I
(giving planting media) consisted of four levels and Factor II (giving compound
NPK fertilizer) consisted of three level. The results showed that the use of
Inceptisol 100% growing media gave a better impact on the increase in the
number of leaves (strands), hump diameter (mm) and the number of flowers
(buds), while the planting medium with husk charcoal mixture showed the fastest
first flower. Dosage of 15g NPK fertilizer per plant gave a better impact on leaf
area (cm2), bulb diameter (mm), flower appearance (days), and number of flowers
(buds).
