Kangkung (Ipomoea reptans Poir) is an annual or annual plant which is an important leaf vegetable in Southeast Asia and South Asia. The purpose of this research was to determine the effect of bokashi fertilizer with different doses of cow dung on the growth and yield of kangkung plants. The research was conducted in November 2017 – January 2018. Planting locations, observations of plant height and leaf number of kangkung plants were carried out in Sidera Village, Biromaru District, Sigi Regency and measurement of chlorophyll content, leaf area, canopy fresh weight, fresh root weight, and total fresh weight of kangkung plants conducted at the Horticulture Laboratory Faculty of AgricultureTadulako University. This research was conducted based on Randomized Block Design (RBD) as the treatment of bokashi fertilizers dosage consisting of 5 levels namely: (A) without fertilizer (control), (B) bokashi fertilizer 7.5 ton/ha, (C) bokashi fertilizer 15 ton/ha, (D) bokashi fertilizer 22.5 ton/ha, and (E) bokashi fertilizer 30 ton/ha, each treatment was repeated 4 (four) times so that there were 20 experimental units.The results showed that cow dung bokashi organic fertilizer had a significant to very significant effect on the growth and yield of kangkung plants on all parameters observed, except for observations of plant height aged 20 days after planting and observations the number of leaves at the age of 20 days after planting. Treatment of bokashi fertilizer with a dose of 30 ton/ha gave the highest growth in all parameters, but not significantly different with the treatment bokashi fertilizer 22.5 ton/ha.
