Phosphorus fertilization and maize intercropping with peanut synergistically reshape rhizosphere microbiome and enhance crop yield.

ABSTRACT:

Introduction

Optimizing nutrient cycling in diversified cropping systems is essential for sustainable agriculture. While intercropping legumes with cereals can enhance complementary resource use, the interaction between phosphorus (P) fertilization and such systems in restructuring rhizosphere microbiomes and driving synergistic productivity gains in alkaline soils remains unclear.

Methods

We conducted a long-term field experiment, integrating amplicon sequencing with comprehensive agronomic and soil analyses to investigate this interaction in a maize-peanut intercropping system under P fertilization.

Results

Phosphorus fertilization significantly increased the yields of intercropped maize (by 52.12%) and peanut (by 43.60%), while simultaneously enhancing the intercro
