Abstract:
Yield and yield attributes of groundnut were evaluated with the application of different levels of phosphorus fertilizer along with FYM, and bio-inoculants during Rabi 2020. The experiment was laid out in Randomized Block Design and replicated thrice, conducted at Agricultural College Farm, Bapatla. The treatments comprised of T₁ - 100% RDP, T₂ - FYM + PSB + VAM (without P), T₃ - 100% RDP + FYM + PSB, T₄ - 100% RDP + FYM + VAM, T₅ - 100% RDP + FYM + PSB + VAM, T₆ - 75% RDP + FYM + PSB, T₇ - 75% RDP + FYM + VAM, T₈ - 75% RDP + FYM + PSB + VAM. The results indicated that the combined application of inorganic fertilizer + FYM + biofertilizer proved significantly superior over - application of FYM and biofertilizers alone without adding inorganic phosphorus fertilizer in obtaining better growth and higher yield of groundnut and the yield was increase with the application of 75% RDP + FYM + PSB + VAM over 100% RDP alone which indicates that the reduction in RDP of 25% could be able to get the good yield by substituting this with FYM, PSB and VAM. The highest shelling percentage and test weight (100 kernel weight) was recorded with the application of T₅ over aT₁.
