Abstract

The aim of this experiment was to investigate effect of  media growth composition and NPK fertilizer dosage toward growth ability of A. angustoiloba from Pendopo Provenance, Muara Enim, South Sumatera. Completely Randomized Design of factorial with two factors (growth media composition and fertilizer dosage) and four levels of each factors were used. Four replications were used with five seedlings per replication. The effects of those treatments were evaluated through seedling height growth, stem diameter growth and number of leaves. The result showed that media composition variations gave very significant effect on height growth and number of leaves of  A. angustiloba seedling for 4 months. The best height growth was produced of top soil + compost (1:1) media (48,51 cm) and the best number of leaves was produced of top soil media (19,89). The fertilizer dosage variations gave very significant effect on height growth, stem diameter and number of leaves of  A. angustiloba seedling for 4 months. The best height growth (49,58 cm), stem diameter (5,93 mm) and number of leaves (20,24) were produced by 1 g NPK fertilizer dosage. Interaction of media composition and fertilizer dosage gave significant influence on height growth and stem diameter of  A. angustiloba seedling for 4 months.The best height growth (52,7 cm) was produced by interaction of top soil + compost (1:1) media and 1 g dosage of NPK fertilizer and the best stem diameter (6,5 mm) was produced  by interaction top soil and 0.5 g dosage of NPK fertilizer.

Abstract

The aim of this experiment was to investigate effect of population sources, media composition and NPK fertilizer dosage toward sprouting ability of Alstonia angustiloba Miq. Cutting. This experiment was arranged in completely randomized design with factorial setting. The research used 3 factors, I,e.population sources (banten, Pendopo, Lubuk Linggau and Solok); media compositions (top soil, top soil : Compost : husk charcoal 3 : 2 : 1, top soil : compost : husk charcoal 4 : 2 : 1, Top soil : compost :husk charcoal 5 : 2 : 1 and top soil : compost : husk charcoal 6 : 2 : 1) and NPK fertilizer dosage (0g,5 g. 10 g, 15 g and 20 g). The results showed that media composition variantions did not give significant effect on parameters measured. The best of length and diameter of sprouts, number of nodus and number of leaves were significantly produced by 20 g NPK fertilizer dosage. Pendopo popupation significantly produced the best length sprouts, while Banten population produced the best number of nodus and Lubuk Linggau population produced the best diameter sprouts and the highest number of sprouts. Interaction of NPK fertilizer dosage and population sources gave significant influence on number of sprouts, whit the best interaction was 10 g dosage of NPK fertilizer vs Lubuk Linggau population (1.79).
