【 摘 要 】

This study aimed to evaluate the role of different formulations and types of organic matter in improving yield and resistance of soybean plants to bacterial pustule disease. The study was prepared based on a randomized block design with a factorial pattern. The first factor was the application of rhizobacterial formulation (biofresh), ie F0 = without the application of rhizobacteria, F1 = application of biofresh in solid formulation, and F2 = application of biofresh in liquid formulation. The second factor was the application of organic materials, namely B1 = compost of soybean litter + cow dung, B2 = compost of rice straw + cow dung, B3 = compost of soybean litter + rice straw + cow dung. Observation of disease severity and soybean yield was conducted on five sample plants in each treatment. The results showed that the treatment of biological agent biofresh in solid formulation combined with compos of soybean litter, was the best treatment in increasing plant resistance to bacterial pustule disease and seed weight. Plant resistance induction occurred systemically characterized by salicylic acid increase of 0.3 mg and peroxidase increase of 0.07 unit / mL in the sample plants.
