This research study on double row cultivation for cassava plant using Adira IV as cultivar and completed by cassava skin compost as substitute fertilizer. The treatment number 1 consist of 20 ton/ha compost, 125 kg/ha Urea, 150 kg/ha TSP and 125 kg/ha KCl. The treatment number II consist of 20 ton/ha compost, 62.5 kg/ha Urea, 75 kg/ha TSP and 62.5 kg/ha KCl. The treatment III consist of 0 ton/ha compost, 75 kg/ha Urea, 100 kg/ha TSP and 75 kg/ha KCl as bassal dressing and 50 kg/ha Urea, 50 kg/ha TSP and 50 kg/ha KCl as second fertilizer. The cassava production by 8 months old were between 22.0 to 27.5 ton/ha, 19.12 to 25.25 ton/ha and to 24.2 ton/ha respectively. By 9 months old, cassava production were 22.6 to 28.77 ton/ha, 19.0 to 21.0 ton/ha and 21.0 to 22.75 ton/ha and by 10 months old cassava production were 21.38 to 28.95 ton/ha, 17.40 to 23.20 ton/ha and 22.13 to 24.50 ton/ha respectively. Those cassava production were not the best one because there were very hard dry season with no rainfall since the plant were 7 months old
