Abstract
Recently Rhizobium-biofertiliser technology has gained prominence in rice cultivation which has provided an excellent opportunity for exploring the possibilities of introducing N‚‚ fixation capability in rice Biswas et al. 2000. An in vitro experiment using a plant growth chamber was conducted to observe the effects of rhizobial or plant growth-promoting rhizobacterial PGPR inoculation on phytohormone production and growth of rice seedlings. Two rhizobial strains and three PGPR strains were selected based on the preliminary test involving their abilities to fix atmospheric nitrogen solubilise phosphate and Indole-3-acetic acid IAA production. These selected rhizobia were isolated from nodules of soybean Glycine max and Mimosa pudica while PGPR were isolated from rice Oryza sativa and oil palm Elaeis guineensis roots. Based on the results these isolates produced beneficial effects on the rice seedlings with increased growth height and bacterial population N‚‚ fixation and phosphate solubilizing properties and IAA production. Strain UPMB10 showed the optimum effects thus could be used as potential isolate for development of liquid biofertiliser for rice and other crops.
