Abstract This research was aimed to study the effect of paclobutrazol concentration and hyacinth liquid organic fertilizer application frequency on growth and yield of Kalosi potato in medium plain. This research was conducted in Gowa regency during August to December 2012 in medium plain at altitude of 490 m above sea level. This research used two-factor factorial experiments repeated twice and continued with Duncan test at significance level of 5. The first factor was the application of growth regulator containing paclobutrazol at concentration of 0 1 and 3 ml l-1 . The second factor is hyacinth liquid organic fertilizer with several application frequencies control two-applications three applications and four application. Study findings indicate that the application of paclobutrazol at the concentration of 3 mll-1 with four applications ofhyacinth liquid organic fertilizer produced the best effect on tuber amount 64.0 tubers compared to the application of paclobutrazol 1 mll-1 water with four applications of fertilizer 54.2 tubers and 1 ml l-1 paclobutrazol application with three applications of hyacinth fertilizer 53.1 tubers. In regards to potatoes tuber weight per plot the application of 3 ml l-1 palcobutrazol with three applications of liquid organic fertilizer produce higher tuber weight 1.99 kg plot-1 compared to the application of paclobutrazol 1 ml l-1 water with three applications of fertilizer and without paclobutrazol application with three applications of fertilizer weighting 1.87 kg plot-1 and 1.49 kg plot-1 respectively.
