Cassava-soybean intercropping alleviates continuous cassava cropping obstacles by improving its rhizosphere microecology.

Introduction: Continuous cropping is the main cause of cassava yield reduction. To find an effective method to alleviate the obstacle of cassava continuous cropping and explore the effect of cassava-soybean intercropping, this study analysed the differences in cassava agronomic traits, yield, soil physicochemical properties, microbial community structure, and metabolites between cassava single cropping (M) and cassava-soybean intercropping (MD) and its effects on continuous cassava cropping soil.

Methods: The correlations between yield, agronomic traits, soil physicochemical properties, microbial diversity, and metabolites were explored, and the effect of the cassava-soybean intercropping model on cassava soil was revealed.

Morphological, anatomical, and transcriptomics analysis reveals the regulatory mechanisms of cassava plant height development.

Background: Cassava is one of three major potato crops and the sixth most important food crop globally. Improving yield remains a primary aim in cassava breeding. Notably, plant height significantly impacts the yield and quality of crops; however, the mechanisms underlying cassava plant height development are yet to be elucidated.
