Effect of an Enterobacter cloacae-based Biofertilizer on the Growth and Performance of Cassava Plants (Manihot esculenta Crantz) MCol 2066 Variety (Chirosa)

Biofertilizers are valuable resources that supply indispensable nutrients for plants, improving the physiological development and agronomic quality of crops, producing vegetable hormones, supporting and promoting a sustainable agricultural production.This study focused on evaluating the impact of an Enterobacter cloacae-based biofertilizer on the growth and performance of cassava plants (Manihot esculenta Crantz), MCOL 2066 variety (Chirosa).The traits associated with plant growth promotion were evaluated employing a biotest under controlled greenhouse conditions, using a completely randomized experimental design.The 16S rRNA gene sequencing reveals the confirmation of Enterobacter cloacae isolates (strain S105E PP405613.1 and FB105B PP761660.1).Under in vitro conditions, it was found that the isolates produced indole acetic acid, solubilized P and fixed nitrogen.The phosphorus (P) solubilizing activity was associated with a simultaneous decrease in the medium's pH (pH 7.0-<4.5).It was found that the biofertilizer induced a significant increase in plant height, root development, and biomass accumulation.As a result, these Enterobacter cloacae isolates could be further formulated for field applications.
