Abstract Tissue culture techniques can increase the number of garlic seedlings. The purpose of this research is to determine the effect of NAA and coconut water in increasing the number of garlic seeds. This research used a Completely Randomized Design of two factors. The treatment used is NAA with concentrations of 0 ppm, 0.5 ppm, 1 ppm, 1.5 ppm, and coconut water concentrations of 0%, 10%, 20%. The variables observed were shoot emergence time, root emergence time, number of shoots, number of roots, number of leaves, shoot height, root length, and number of plantlets. The results showed that the addition of coconut water 20% without the addition of NAA in 1 bulb can produce 3.33 planlets and the results of explant propagation in 1 bulb can produce the number of shoots as many as 15.33 shoots. Giving coconut water with concentrations of 10% and 20% can increase the number of leaves, shoot height, and some planlets. The concentration of NAA 0.5 ppm can accelerate the root emergence time on garlic explant.
