The study aimed to improve groundnut growth and yield by using Rhizobium inoculation, along with Phosphorus and Nitrogen fertilization. The researchers conducted the experiment in Malaysia and found that the plants treated with Rhizobium and fertilizers had the best growth and yield, including taller plants, more branches, nodules, and pods, higher pod yield, seed weight, oil and protein content, and better seed germination. This suggests that using Rhizobium with specific amounts of P and N fertilizers can significantly enhance groundnut production.
