A field experiment was conductedduring the summer season of 2022 to study the effect of two forms of
phosphorus (super phosphate and rock phosphate), humic acids, and plant growthpromotingrhizobacteria(PGPR) on peanut yield (Arachishypogaea L.) cv. Giza 6. Data showed that humic acids,
a mixture of superphosphate and rock phosphate, and PGPR especially those produce exopolysaccharides are
crucial for the growth and yield of peanut plants. A superior increase in the effect of humic acids, followed by
phosphorus applications on plant height, number of pods per plant, pod weight per plant, seed weight per plant,
100 pod weight, 100 seed weight, pods and seed yields, and shelling percentage was recorded. The coinoculation with PGPR especiallythatproduces exopolysaccharides, can affect peanut yield and the
abovementioned yield attributes and shelling percentage.Moreover, the application of humic substance resulted
in significant increases in protein and oil content compared to untreated samples. Finally, the combination
ofhumic acids,PGPR, and mixture of super phosphate and rock phosphate resulted in significant increases in all
quality parameters of peanuts as compared to untreated ones.
