PEMBERIAN KOMPOS KULIT BUAH KAKAO DENGAN DOSIS YANG BERBEDA PADA PERTUMBUHAN BIBIT KARET (Hevea brasilliensis)
Pod husks compost is a fertilizer that can stimulate the growth of roots, stems, leaves, stimulate the activity of soil microorganisms more effective and able to restore soil fertility. The purpose of this study was to determine the effect of compost pod husks with different doses on the growth of seedlings of rubber (Heveabrasilliensis). This study was conducted over three months, starting from November 2014 until February 2015, which includes the preparation, execution and data retrieval. This research was conducted in the area of the Laboratory of Agricultural Polytechnic State Samarinda.Penelitian production uses three levels of treatment that is P0 (control ), P1 (100 gr / polybag compost from pod husks), P2 (200 gr / polybag komos from pod husks), each treatment was repeated 15 times repetition so that the number of plants is 45 rubber seedlings. From the results of the study showed that the P2 (200 gr / polybag compost from pod husks) on all the meters of good plant height, leaf number and stem diameter of the fastest growing. The high growth of plants of weeks of 2, 4, 6 and 8 are 42.39 cm, 52.92 cm, 53.01cm and 62.73 cm, the highest increase in the number of leaves of weeks of 2, 4, 6, and 8 are 12 pieces, 18 pieces, 19 pieces and 23 strands. Growth in the number of the largest meter diameter seen at week 2, 4, 6 and 8 are 5.4 mm, 6.2 mm, 6.5 mm and 7.8 mm.
