Application of root exudates derived from peanut/maize intercropping system promotes peanut growth and yield via modulating nitrogen turnover processes.

ABSTRACT:

Background

Legume-based intercropping systems function in boosting crop productivity. However, the precise physiological mechanisms by which root exudates derived from these systems on crop growth have not been characterized. Here, the rhizosphere soil from a peanut/maize intercropping system was analyzed for metabolome profiles. Sucrose (SUC) and myo-inositol (MI) were significantly declined while oxalic acid (OA) was dramatically enriched compared with peanut monoculture. After concentration screening, the optimal concentrations of OA, SUC, and MI have been determined as 1.0 g/pot, 0.1 g/pot, and 0.1 g/pot, respectively. Armed with the optimal concentrations, OA, SUC, MI, and their combinations were applied to peanut soil, respectively.
