Acclimatization of Rhizosphere Bacterial Communities by Pea Cultivated under Different Agriculture Practices

Conservation agriculture offers a suitable system to harmonize agriculture with the environment especially in fragile ecosystems of North-East India. Soil microbes play key roles in ecosystem functioning and are the key indicators of overall fitness of crop plant and soil health. Here we demonstrated that nutrient management and tillage practices lead to the development of heterogeneous bacterial communities and pea plants recruited a special group of bacteria leading to highly homogenous communities. Pea rhizosphere and bulk soil samples were collected, and bacterial community structure was estimated by 16S rRNA gene amplicon sequencing and predictive functional analysis was done using Tax4Fun.
