Background and Aims Plant growth and ecosystem processes in semiarid regions are limited by soil nutrient and water availability. Nitrogen (N) and phosphorus (P) status and the N:P ratio alterations among plant organs are critical in understanding the physiology and productivity of the grass-legume mixture system. This study aimed to identify the N and P distribution patterns and N:P stoichiometry of a local grass species mixed with a legume species under varying water and fertilizer supplies.
