Response of Growth of Garlic Towards Aspergillus niger and Fusarium sp. Inoculant

Garlic is one of the main commodities in Indonesia.Various constraints in the cultivation system such as the condition of the land and attacks of diseases such as root wilting are problem of increasing the productivity of this plant. This study aims to obtain information about the effect of giving inoculants of Aspergillus niger and Fusarium sp on the growth of garlic in different media planting until the age of 20 days. Garlic bulb were obtained from local farmers, with a size of weight 6-7 gram/bulb. The experiment was carried out at the greenhouse scale using a completely randomized design with 5 replications. Treatment includes the type of planting media, soil, sand and soil + sand (ratio1:1), three type of inoculant, Aspergillus niger, Fusarium sp and mixing Aspergillus niger + Fusarium sp and control. Inoculants are given 10 mL (5 x 10¹⁰ CFU/mL) in liquid on pots containing 300 grams of planting media. Observations are carried out after 20 days planting. The results showed that Aspergillus niger and Aspergillus niger + Fusarium sp inoculants had a positif significant effect on the growth of garlic in all treatment media soil, sand and soil + sand. Fusarium sp inoculant inhibits growth of 30% - 60%, Aspergillus niger inoculant can increase growth of 40% - 90% when compared to controls on all planting media. The use of Aspergillus niger inoculant can overcome diseases caused by Fusarium sp, it can even increase the growth of 30% - 40% in sand and sand + soil media planting.
