Widawati S.2015.The role of Functional Bacteria Resistant Saline (PGPR) on the growth of rice in sandy soil saline. Pros Sem Nas Masy Biodiv Indon 1: 1856-1860. Functional saline resistant bacteria is very important in improving the quality of soil biological and chemical as well as play an important role in the food chain cycle. This study was conducted to determine the extent of the saline resistant bacterial effect on the growth of rice planting medium is saline. The study was conducted in a greenhouse at the Research Center for Biology LIPI Cibinong science center. Research using completely randomized design with four replications in 26 combined treatment (A, B, C, D, E, AB, AC, AD, AE, BC, BD, BE, CD, CE, DE, ABC, ABD, ABE, BCD, BDE, CDE, ABCD, ABCE, BCDE, ABCDE, Control). Code A= Bacilus megaterium strain KWiL1.1; B= Bacillus thuringiensis strain KWiL1.2; C= Bacillus pantothenticus strain KWiL1.3; D= Azospirillum lipoferum strain KWiL1103C; E= Azotobacter crococcum strain KWiL14103). Results showed that a single bacterium (Azospirillum lipoferum strain KWiL1103C) and ABCDE combination (Bacilus megaterium strain KWiL1.1; Bacillus thuringiensis strain KWiL1.2; Bacillus pantothenticus strain KWiL1.3; Azospirillum lipoferum strain KWiL1103C; Azotobacter crococcum strain 14103) has a significant role in the growth and production of rice on sandy soil waterlogged and saline, scale greenhouses.
