Abstract
Research on Benefit of Using Concentrations PGPR (Plant Growth Promoting Rhizobacteria) Coffe Roots on Growth of Roots Robusta Coffe (Coffea canephora Pierre ex A Froehner) is one of methods to increase the growth and quality of coffe plants are using PGPR (Plant Growth Promoting Rhizobacteria).this research was aimed to search effective used concentration of PGPR (Plant Growth Promoting Rhizobacteria) to increase the growth of coffe plants. The experiment was conducted 3 months in state Polytechnic of Jember start from 27th Oktober 2019 until 18 rd February 2020. One Factorial randomized blok design was used as the experimental design wich consist one factors. The factor used is concentration of PGPR (Plant Growth Promoting Rhizobacteria) 0 cc/Liter, 30 cc/Liter, 60 cc/Liter, 90 cc/Liter. The result showed that concentration PGPR (Plant Growth Promoting Rhizobacteria) of 0 cc/Liter, 30 cc/Liter, 60 cc/Liter, 90 cc/Liter non significant effect of roots length,total root, and root volume. PGPR (Plant Growth Promoting Rhizobacteria) concentration 54 cc/Liter significant effect of root weight, root dry weigh, delta wet weight and dry weight, and PGPR bacterial density.
