Field evaluation of nursery bed inoculated arbuscular mycorrhiza and rootdip inoculated Azotobacter chroococcum and Aspergillus awamori on aerobic rice

Abstract

Field evaluation of nursery bed inoculated with Glomus fasciculatum and root dip treatement with Azotobacter chroococcum and Aspergillus awamori was carried out on aerobic rice. All the inoculated treatments with G. fasciculatum either singly or incombination showed increased growth and yield of rice compared to control and dual and triple inoculation were performed better than single inoculation treatment. G. fasciculatum inoculated seedlings in nursery bed shown better root colonization in field after transplantation compared to un-inoculated plants. The root dip inoculation with A. chroococcum and A. awamori during transplantation also increased the population of N 2 fixer and Phosphate solubilizers besides increasing the population of general microflora in the rhizosphere. The results revealed the possibility of nursery inoculation of arbuscular mycorrhiza and root dip inoculation of other biofertilizers for aerobic rice.

Arbuscular Mycorrhizal Fungi and Microbes Interaction in Rice Mycorrhizosphere

“…Recent advances have shown that microbial consortia containing mycorrhizal inoculant are effective [130,131]. Microbial consortia showed increased growth and yield of rice compared to the control [132,133]. The interaction effect of consortium of Azospirillum, PSB, and AMF fungus could reduce levels of N and P fertilizers in the growth of directly seeded rice [134].…”

Deciphering the Structural and Functional Diversity of Rhizobacteria from Stone Pine Inoculated with Plant Growth Promoting Rhizobacteria (PGPR) before and after Transplanted into Degraded Agricultural Soil

“…By increasing the nutrient status and quality of the soil, these advantageous microorganisms that form colonies in and around root systems support plant growth. Research has demonstrated the favorable effects of applying microbial consortia made up of particular microorganisms on plant growth, particularly when the microorganisms are inoculated in nursery beds or root trainers during the seedling stage [16,17].…”
