During Rabi 2022, the nutrient content of sorghum were evaluated after being treated with different levels of phosphorus fertilizer and biofertilizers. At the Agricultural College Farm in Bapatla, the experiment was set up in a randomized block design and duplicated three times. The treatments comprised of T₁- 0% RDP, T₂- 50% RDP, T3- 75% RDP, T₄- 100% RDP, T₅- 0% RDP + PSB, T₆- 0% RDP + PSB + VAM, T₇- 50% RDP + PSB, T₈ -50% RDP + PSB + VAM, T₉ -75% RDP + PSB, T₁₀- 75% RDP + PSB + VAM. N, P, K, and micronutrient levels in the plant samples were determined using standard methods. The experiment showed that the treatments had a significant effect on P and Zn, whereas no effect on N, K, Fe, Mn, or Cu. The treatment (75% RDP + PSB + VAM (T₁₀) had the maximum nutrient content and it is on par with 100% RDP (T₄). Therefore, the nutrient content of sorghum was considerably enhanced by the combined application of inorganic fertilizer and biofertilizer compared to both the control and biofertilizers alone.
