RESPON PERTUMBUHAN STEK BATANG BUAH NAGA (HYLOCEREUS COSTARICENSIS) TERHADAP LAMA PERENDAMAN DALAM AIR KELAPA DAN DOSIS ECOENZIM

Abstract

This research aims to see the response of dragon fruit stem cuttings to the length of soaking in coconut water and the dose of ecoenzymes and to determine the interaction between the two treatments. This research was conducted in Suka Makmur Village, Dusun II Suka Malem, Kutalimbaru District, Deli Serdang Regency, with an altitude of 125 meters above sea level and was conducted from March to May 2023. This research used a factorial Randomized Block Design (RAK) consisting of 2 factors. The first factor is the length of soaking in coconut water (A) which consists of 4 treatment levels, namely Ao = 0 hours (no soaking), A1 = 4 hours soaking, A2 = 8 hours soaking, and A3 = 12 hours soaking., second factor namely the dose of ecoenzyme (E) which consists of 4 treatment steps, namely Eo = 0 ml (without ecoenzyme), E1 = 6 ml of ecoenzyme, E2 = 10 ml ecoenzyme, and E3 = 14 ml ecoenzyme. Data analysis uses variance. The parameters observed in this study consisted of shoot emergence time, number of shoots, shoot length, number of roots, root length, net wet weight of roots, net dry weight. The research results showed that the length of soaking in coconut water had a significant effect on shoot length after 8 hours of immersion at 4 WAP, but had no real effect on the time of shoot emergence, number of shoots, shoot length at 8 and 12 WAP, number of roots, root length, net root weight. , net dry weight of roots. The ecoenzyme dose had a significant effect on root length with a dose of 14 ml, whereas the net root weight and net dry weight of the roots had no significant effect on the control treatment.
