The plant cuttings is one of the most common methods of vegetative reproduction which is,today, used extensively due to low cost. In order to study the effect of various concentrationsof Naphthalene acetic acid (NAA) and Indole acetic acid (IAA) on the rooting of semihardwoodcuttings of Dalbergia sissoo , an experiment was carried out in a private field inKoya city in 2014. In this research, the treatments were prepared to include hormone ofNaphthalene acetic acid in four levels of: (0, 100, 300 and 500 ppm) and Indole acetic acid infour levels of: (0, 100, 300 and 500 ppm), and the bottom part of the cutting was dipped intoabove solutions for 30 seconds. The results showed that the maximum percentage of theshooted cuttings, shoot length, number of main branch, diameter of main branch, leaf area,number & length of root, dry weight & biomass &dry matter of shoot, fresh &dry weight ofroot, biomass &dry matter of root and chlorophyll a belonged to IAA treatment withconcentration of 500 ppm, NAA treatment with concentration of 500 ppm. Nitrogen andprotein increased with concentration 300 ppm for IAA amd NAA auxins. The highest lengthof root belonged to IAA treatment with concentration of 500 ppm. All growth parameterswere increased up to the highest concentrations of IAA 500 ppm. IAA was the most effectivein promoting growth of Dalbergia sissoo cuttings.
