Pengaruh Dosis Pupuk Organik dan Interval Pemberian Pupuk terhadap Pertumbuhan Semai Mahoni (Swietenia macropylla King)

BSTRACT This was to determine the interaction between giving and applying fertilizer to
mahogany seedlings From the results of the study it is known that the interaction of the
effect of organic fertilizer dosing and interval of organic fertilizer administration on the
growth of wide leaf mahogany (S. macrophylla King) plant on seedling leaves and stem
diameter. The seedling leaves significantly affected 7 mss with a combination of P1M2
treatment, namely the provision of 10 gram / polybag organic fertilizer and the 2 week
interval of organic fertilizer administration with the highest average of 7.80 The results of
the analysis on the stem diameter that significantly affected 6 mss and 8 mss, 8 mss with
a combination of P2M3 treatment giving a dose of organic fertilizer 20 grams / polybag and
the interval of giving organic fertilizer 3 weeks with the highest average of 6.83 mm
compared to the leaves of the seedlings in the treatment treated the same but the average
yield of 7.43 seedlings because the seedlings absorb nutrients well. The conclusion from
all of the research that I did the best was P3M2 30 gram organic fertilizer dose with 2
weeks organic fertilizer interval due to organic fertilizer dosage with appropriate organic
fertilizer interval at mahogany seedlings.
