The purpose of this research is to ascertain how growth regulator concentration and type affect lime shoot cuttings (Citrus aurantifolia) growth. From November 2022 February 2023, study was carried out in Dusun III Pandanan Dukuh Biru RT 03/RW 01, Wonosari District, Klaten Regency, Central Java. At an elevation about 118 meters above sea level, the site located. This employed a CRD (completely randomized design) with two factors, namely three ZPT types at (Z1: extract onions, Z2: coconut water, Z3: IBA Chemical Hormones) concentrations (K1: 25%, K2: 50% , K3 : 75%). There were 108 experimental units totaling 36 four replications sample plants each. percentage living cuttings, age which shoots appeared, height shoots, number leaves, root length parameters that observed. used One-Way ANOVA test variance (Test F) levels 5% 1% analyze data. level 5%, continued Duncan Multiple Range Test (DMRT) examination. According findings research, treatment various PGR significantly affects emergence, plant height, leaves. had significant impact on length, but there no interaction between any observed parameters.
