Abstract:
The effects of the inoculation of plant growth promoting rhizobacterial (PGPR) strains Bacillus cereus BSB 38 (14B) Pseudomonas jessenii R62, Pseudomonas synxantha R81, Arthrobacter nitroguajacolicus strainYB3 and strain YB5 on grain yield and grain nutrient content for four genotypes of rice namely, Swarna, Swarna sub1, IR-64, and IR-64 sub1 under field condition. Two consortia, one is Pseudomonas jessenii and Pseudomonas synxantha (R62 + R81), another consortia of Arthrobacter nitroguajacolicus strain YB3 and YB5 (A3 + A5), and one Bacillus species (14B) were used as a bioinoculant. Under field condition, PGPRs treated plants showed higher grain yield as compare to their respective control. In all the varieties the grains of inoculated plants had remarkably higher quantity of protein and carbohydrates as well as phosphorus and potassium in respect of their control plants. The grains of treated plants had efficiently higher quantity of four micronutrient, like iron (Fe), manganese (Mn), zinc (Zn) and copper (Cu). Present result indicated that the selected PGPR had greater effect on the nutrients mobilization in rice seeds and thus have shown to be a valid option for sustainable high quality rice production to improve the nutritional status and health of the population.
