    Abstract

    Piper is an export commodity and become the one of Indonesian source of income. It is necessary to develop the best cultivation for increasing piper’s production, and the vegetative propagation have been choosen in this research using organic fertilizer as part of media and auxin as a growth hormone. The aim of research is to find the best media and auxin’s concentration for ideal growth of piper’s grafting. The research conducted in Manyaran Wonogiri from August until November 2008 with RCB design consist of two factors and arranged in factorial. First factor is kind of media (soil, soil + organic fertilizer, soil + organic fertilizer + husk) and the second is auxin’s concentration (0 g/l, 12.5 g/l, 25 g/l, 37.5 g/l; 50 g/l). Observation’s variable are: bud growth time, number of buds, length of bud, number of leaves, leaf’s area, number of roots, length of root, and life percentage of cuttings. Data was analyzed by F test 1% and 5% and be continued with DMRT at 5% if the treatment had significant effect. It is also continued with regression if there was interaction between the treatment. The longest bud was found on soil + organic fertilizer + husk (12.28 cm) and followed by soil + organic fertilizer (10.57 cm) and soil (6.15 cm) in the low level respectively. The length of bud and number of roots were influenced by auxin’s consentration. The longest bud was found by using 12.5 g/l of auxin (15.14 cm) and followed by 50 g/l, 25 g/l, 0 g/l, and 37.5 g/l in the low level respectively (12.05 cm, 7.72 cm, 7.67 cm, 5.75 cm). The highest number of roots was found on 0 g/l and 12.5 g/l of auxin (7.78) and followed by 50 g/l, 25 g/l, and 37.5 g/l in the low level respectively (4, 3.43, 2.33). Interaction between two factors was shown by number of roots and percentage of life cuttings. Number of roots on soil shown parabolic respon with auxin. In the beginning, number of roots decreased and then increased with increasing of auxin’s consentration. The number of roots on soil + organic fertilizer and soil + organic fertilizer + husk shown the same pattern with auxin’s consentration. Almost 100% of life cuttings have been found on all of media and auxin’s consentration. Soil + organic fertilizer with 25 g/l auxin and soil + organic fertilizer + husk with 50 g/l auxin caused 33.33% and 66.67% life cuttings respectively.
