PENGARUH PANJANG STEK DAN KONSENTRASI AIR KELAPA TERHADAP PERTUMBUHAN BIBIT TANAMAN BUAH NAGA (HYLOCEREUS COSTARICENSIS)

Dragon fruit is one of the horticultural commodities classified as fruit species which has many benefits and high economic value. This study aims to dete rmine the length o f cuttings an d th e conce ntration of young coconut water that is suitable for the growth of dragon fruit cuttings. This research was conducted in the Kampung Jawa, Blangkejeren Subdistrict, Gayo Lues Regency, lasted from November 2018 to March 2019. This research uses a compl etely rando mized design (CRD) factorial pattern 3 x 5 with 3 replications so that there are 15 treatment combinations and 45 experimental units. The first factor of cuttings size consists of 3 levels, namely 15 cm, 20 cm and 25 cm, while the coconut water concentration factor consists of 5 levels, namely control, 25%, 50%, 75% and 100%. The results showed that the length of cuttings significantly affected the number of shoots aged 90 HST, significantly affected the length of shoots aged 60 and 90 HST, the wet budding weight of the buds, the dry budding weight of the shoots and the dry root weight of the shoots. The concentration of young coconut water significantly affected the number of shoots at the age of 90 HST, which was best in the treatment of young coconut water concentration 50%, had a very significant effect on the diameter of the base of shoots of age 90 HST. and 90 HST is best in the treatment of Young coconut water concentration of 75% and 50%, the best time for emergence of shoots is in the treatment of Young coconut water concentration 100%, the best wet wet buds in the treatment of Young coconut water concentration 5 0%, heavy The best dry bud buds were found in the 50% concentration of Young coconut water treatment and the best effect on the dry root weights were best in the 75% young coconut water concentration treatment. The results showed an interaction between cuttings size and concentration of young coconut water on the growth of dragon fruit plant seeds. The best combination was found in the highest cuttings length treatment at P2 and P3 and young coconut water concentration at 50% and 75% treatment. While the lowest cuttings length was in the control treatment and the concentration of young coconut water in the control treatment and 100%.Keywords : Dragon fruit, Cutting lengh, Young Coconut wate
