Pengaruh Pemberian Amelioran Organik dan Anorganik pada Media Subsoil Ultisol terhadap Pertumbuhan Bibit Kelapa Sawit (Elaeis guineensis jacq.) Di Pre Nursery
Abstract: The aim of the
research was studied the effect of application of organik and inorganik
ameliorants on the growth of pre nursery oil palm seed (Elaeis guineensis
Jacq.) on Ultisol subsoil. This research was done at Bina Widya Campus of Riau
University, Km. 12,5 Panam, Pekanbaru. The field research used Soil Science
Laboratory and Agriculture Faculty. This research used statistic factorial in
Completely Randomized Design (CRD). The first is organic ameliorant consist of
oil palm empty fruit bunches compost (OPEFBC) and cocopeat (C) with 6 levels
(O0= without ameliorant, O1= 100 g OPEFBC, O2= 100 g C, O3= 50 g OPEFBC + 50 g
C, O4= 50 g OPEFBC + 100 g C, O5= 100 g OPEFBC + 50 g C), the second is
inorganic ameliorant consist of drges and fly ash with 4 levels (A0=
without ameliorant, A1= 50 g dregs, A2=
50 g fly ash and A3= 25 g dregs + 25 g fly ash)/ 2 kg soils. The result of
combination organic ameliorant (50 g OPEFBC + 100 g C) and inorganic ameliorant
(50 g fly ash) increased plant hight, number of leaves, stem diameter and leaf
area compared to control and application of organic ameliorant (100 g OPEFBC)
and inorganic ameliorant (50 g dregs, fly ash or mix).
