【 摘 要 】

One of the factors causing the low productivity of red onion is the low soil fertility. Some efforts are needed to improve Ultisol fertility through improved cultivation technology. Increasing the fertility of Ultisol soils can be carried out by adding kirinyu compost and mycorrhizal inoculation so that plants can absorb nutrients maximally. Research on the application of kirinyu compost and mycorrhizal inoculation was carried out in 2018. This study used a randomized block design (RBD) consisting of two factors; which were: kirinyu compost dosage (0, 200, 400, and 600 g/plant) and mycorrhizae dosage (3, 6, and 9 g/plant). The results showed that the treatment of compost to 600 g/plant increased plant height, number of leaves, number of tillers and tuber weight for of plant. Mycorrhizal inoculation up to 9 g/plant was not able to increase plant height, number of leaves, number of tillers and tuber weight of plant. There were no interactions between the dosage of compost and mycorrhizal on all observed parameters. There was an increase in Ultisol soil fertility through the addition of kirinyu compost and mycorrhizae.
