Effectiveness of microbial consortium on growth, yield, and intensity of withered disease (Fusarium oxysporum Schelecht) on garlic plants

Garlic is one of the horticultural products that is further developed in Indonesia, this is done as one of our efforts to increase the needs of meeting the needs of products that always rely on imports. The productivity of our garlic is still low, below 20 tons/ha. To improve this efficiency, technology development is needed, one of which is by using a microbial consortium. The utilization of the microbial consortium in garlic cultivation is still limited. This study examines the best benefits of the microbial consortium for growth (height, number of leaves) and yield quality (tuber diameter and yield) as well as its effect on the development of wilt disease caused by Fusarium oxysporum Schelecht. The research was conducted at the Vegetable Crops Research Institute (Balitsa) from August to November 2018 using a Randomized Block Design consisting of 6 preparations and 4 replications. The approved microbial treatments were P0 (Control), P1 (12.5 g/plant), P2 (25 g/p lant), P3 (50 g/plant), P4 (100 g/plant), and P5 (150) g/plant). The results showed that the use of 150 gr microbial consortium showed the highest value for high plant parameters, while for the number of leaves, yield weight, tuber diameter did not show differences between workmanship. The influence of the use of a microbial consortium can control fusarium disease at 40 days after planting (HST) of 14.7-41.17 percent compared with control management.
