The purpose of this research was to determine the effect of giving natural PGRs on the growth of Siamese orange plant cuttings and to obtain natural PGRs with the best growth in Siamese orange plant cuttings. The research was conducted at the Siam Kuok orange plantation at km 20, Pekanbaru – West Sumatra provincial highway, Salo District, Kampar Regency. The research was carried out for three months starting from May to July 2022. The research was carried out using a non-factorial completely randomized design (CRD) consisting of 4 treatments with 5 replications. The natural growth regulator (Z) treatment given was as follows: (Z0) = without natural ZPT (control) (Z1) = 75% shallot extract (Z2) = 50% coconut water extract (Z3) = 75% cow urine extract. Observations included age at shoot emergence, number of shoots per plant, shoot length, fresh shoot weight, dry shoot weight, root volume, and live percentage.. The results showed that cow urine nutrition with a concentration of 1600 ppm (Z3) in siamese orange is the best concentration of PGRs in increasing The growth of Siamese orange plants mainly depends on the fresh weight and root volume of Siamese orange seedlings.
Keywords: cutting, cow urine, orange siamese, PGRs.
