PENGARUH KOMPOSISI MEDIA TANAM DAN PEMBERIAN DOSIS PUPUK PGPR (Plant Growth Promoting Rhizobacteria) TERHADAP PERTUMBUHAN SEMAI KETIMUNAN (Gyrinops versteegii)

The aims of this research were to identify the effect of planting media and the giving of fertilizer PGPR. The method applied in this research was an experimental method using complete random planning that consists of 2 factorial. The first-factor consists of 4 borders: compost (P¬¬0), compost+cocopeat with proportion 1:1 (P1), cocopeat (P¬2), and compost+cocopeat with proportion 1:2 (P3). The second factor was without the fertilizer PGPR (F0), fertilizer dosage 100 ml (F1), fertilizer dosage 200 ml (F2), fertilizer dosage 300 ml (F3). The combination of those factors yield 16 treatments, each combination of the treatments was repeated 3 times, in which every repetition had 4 plants, that the number of the samples was 192. The observed parameters in this research were the percentage of the growing plants, the height of the plant, the diameter of the stem, the number of the leaves plants, and the strength of the plants. The result of the observation was tested using analysis of variance at a level of reality 1%. The result of the observation showed that planting media and fertilizer PGPR had an insignificant effect on the observed parameter.
