Abstract
The aims of this research were to investigate the effect of Plant Growth-Promoting Rhizobacteria (PGPR) and P fertilizer on anthtracnose caused by Colletotrichum sp. , plant growth and yield of hot pepper under field condition.. The research was arranged in split plot design with two factors. The first factor is aplication of PGPR which consists of two treatments; without PGPR and with PGPR.. The second factor is application of P fertilizer which consists of four treatment of SP 36 fertilizers; 250 kg , 187.5 kg , 125 kg, and 62.5 kg . Application P fertilizer affect growth parameters of chili pepper but have no effect on antrachnose disease. PGPR was able to control antrachnose under field application, and promoted plant growth parameters and yield. PGPR application increase emergence rate and vigor index of treated seeds. There was interaction between PGPR and P fertilizer dose regarding with growth, with optimum field dose is 125 kg SP 36/ha.
