International Conference on Reimagining Rainfed Agro-ecosystems: Challenges &
Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
Conclusions
1. Use of treatment (T6) Seed treatment + Soil application of microbial consortia (C2)
produced significantly higher Grain and straw yield, GMR, NMR and B:C ratio insorghum
under moisture stress condition.
2. The dual inoculation of microbial consortia culture (C2) through Seed treatment and
soilapplication significantly increased moisture retention and proline content of soil
atharvesting stages of sorghum crop.

Plants and microorganisms have coevolved over the years. The plant microbiome comprises
of rhizospheric, endophytic and epiphytic microorganisms (Rout 2014). Rhizo-microbiome
significantly influences the plant health, growth and productivity (Chaudhari et al. 2020).
They play a vital role in managing various biotic and abiotic stresses. Increased scarcity and
competition for water has become a key threat to food security and poverty alleviation.
Drought considerably changes the composition of bacterial and fungal communities
indicating that, this restructured microbiome might help the plant survival under adverse
environmental situations (Santos-Medellin et al. 2017). Thorough knowledge of crop specific
microbiome would help to modulate the microbiome in a way that would lead to better
growth and development of crop plants (Rascovan et al. 2016). Keeping this in view, a study
was conducted to know the effect of soil moisture stress on the composition of maize root
associated bacteria.
