Abstract


The research aims to find out the effect of pre-germination treatment seeds using rhizobacteria as plant growth promotion of two varieties of red chili peppers in the field. The experiment used a randomized design of factorial groups. Factors studied were varieties (V) and rhizobacteria types (R). The variety factor consists of 2 varieties namely PM999 (V1)and Kiyo F1 (V2). While the type of rhizobacteria factor tried consists of 8 treatment, namely, control (R0), Azotobacter sp. (R1), B. megaterium (R2), P. atmuta (R3), B. alvei (R4), Flavobacterium sp. (R5), B. coagulans (R6), B. firmus (R7) and B. pilymixa (R8). Each treatment was repeated 3 times, so there were 48 experimental units. Each unit of experiment is represented by 5 sample plants. The data was analyzed using ANOVA, and continued with DMRT test at real level α = 0.05. The results showed that vegetative growth and production of chili plants until the age of 45 days after planting in each variety is not dependent on the pre-germination treatment of seeds with rhizobacteria. But the varieties of chili plants used affect vegetative growth and production. PM999 varieties are superior to the Kiyo F1 variety. Pre-germination treatment of seeds using rhizobacteria is relatively effective in improving vegetative growth and yield of chili plants. Among the 8 isolates rizobacteria isolate B. megaterium, Azotobacter sp., P. dimuta, B. alvei, and B. firmus relatively effective to provide an increased effect on the growth and production of chili plants.
