Research aimed at increasing the production and productivity of red chili by using PGPR and NPK fertilizer in dry land has been carried out at the Teaching and Research Farm, Faculty of Agriculture, University of Jambi (35 m asl.). The research uses a Random Block Design with factorial patterns and three replications. The treatment that was tried was the concentration of PGPR and NPK fertilizer dose. The PGPR concentration consists of: 0 mLL-1; 10 mLL-1; 20 mLL-1; 30 mLL-1; and NPK fertilizer doses consisting of: 0 kgha-1; 350 kgha-1; 700 kgha-1. Data were analyzed using Analysis of Variance and continued with the BNT test. The results showed that the interaction of PGPR and NPK fertilizer was not able to increase the growth and yield of red chili, but PGPR was able to increase the number of fruits and the weight of red chili, while NPK fertilizer was able to increase the diameter of red chili plants aged 8 Week After Planting (WAP). PGPR 10 mLL-1 concentration gives the highest number of fruit and fruit weight to red chili, and NPK fertilizer dose of 700 kg ha-1 is a dose that gives the highest shoot diameter. The provision of PGPR to red chili plants has not been able to reduce the use of NPK fertilizer in Ultisol dry land. The weight of red chili produced by administering PGPR 10 mLL-1 is only able to meet 65,33 % of the potential yield of red chili.
