The local type of shall ot known as the Sabu Raijua cultivar has the potential to be developed using technology. One way to increase the shallot production of the Sabu Raijua cultivar is by applying organic fertilizers. The purpose of the study was to determine the dosage of organic and mycorrhizal fertilizers on the growth and yield of onion Sabu Raijua. The research was conducted in the Horticulture Industrial Technology practice garden, Lasiana Village, Kupang City, in August - October 2019. The research design used a factorial experiment with a divided plot design with 10 treatments and 3 replications. The parameters observed were the main variables; plant height, number of tillers, number of leaves, wet weight / plant, number of tubers per plant, dry weight of plants, number of tubers per plot; an additional variable was the initial soil analysis.The results of variance were that the fertilizer dose had no significant effect at 2 WAP and 4 WAP while at the age of 6 WAP, 8 WAP had a significant effect on plant growth. The components of plant height growth, number of tillers and the highest number of leaves were found in manure treatment (43,997 cm; 11,486 trees; 78,886 strands) and the components of plant height growth, number of tillers and number of leaves were found in the treatment of mycorrhizal dose 55 g / plant (45,135 cm; 12,418 trees; 86,378 strands) while the crop yields were treated with manure and mycorrhizal doses of 15 g / plant, 30 g / plant, 45 g / plant and 55 g / plant to tuber weight per plant, number of tubers per plant, tuber dry weight and the number of tubers per plot had a significant effect on crop yield. The highest yield components of wet weight per plant, number of tubers per plant, dry weight of tubers and number of tubers per plot were found in the manure treatment (87,253 g; 18,503 g; 15,760 g; 1394.68 g) and components of yield of wet weight per plant, number of tubers per plant, tuber dry weight and the highest number of tubers per plot were found in the treatment of mycorrhizal doses of 55 g / plant (98,305 g; 20,815 cloves; 17,405 g; 1661.43 g) so that the growth and yield of plants with manure treatment and mycorrhizal dose of 55 g / plant best.
