Abstract


Response of growth and yield of sorghum (Sorghum bicolor (L.) Moench) by giving of arbuskula
mycorrhiza fungi (FMA) and vermicompost. Sorgum is one of the important food crops in the
world. Most of its yield is used as food, beverages, animal feed, and industrial needs. Increasing
of degraded land area and land degradation rate that being higher, so that it needs to improve
soil condition and enchance plant growth by using of FMA andvermicompost. The aim of this
research was to obtain the right dosage of FMA and vermicompost for growth and yield of sorgum
(Sorghum bicolor (L) Moench.). The research was conducted in the field UPT BBI in the Tanjung
Selamat village of Sunggal sub-district, Deli Serdang regency in North Sumatra, in May to August
2012, using a randomized block design (RBD) factorial with two factors and three replications . The
first factor is the dosage of FMA (0, 5, 10 g / plant). The second factor is the dosage of
vermicompost (0, 30, 60, 90 g / plant). The results showed that FMA significantly affect on plant
height, number of leaves, and the degree of root infection. Vermicompost significantly affect on
plant height and number of leaves. Interaction between the giving of FMA and vermicompost
significantly affect on the degree of root infection.
