Abstract:
An field experiment was carried out at Agricultural college farm, Bapatla during rabi season 2022-2023. The experiment was laid out in Randomized Block Design and replicated thrice, consisting of eight treatments to evaluate the effect of inorganics, organics and biofertilizers on growth and yield of rabi groundnut in coastal sands. The treatments comprised of T₁ – Farmer’s practice, T₂ – 75% RDN, T₃ – 100% RDN, T₄ – 75% RDN + 25% N through FYM + consortium (Rhizobium + PSB + KSB), T₅ – 75% RDN + 25% N through vermicompost + consortium (Rhizobium + PSB + KSB), T₆ – 100% RDN + 25% N through FYM+ consortium (Rhizobium + PSB + KSB), T₇ – 100% RDN + 25% N through vermicompost + consortium (Rhizobium + PSB + KSB), T₈ – Control. The results indicated that the combined application of inorganics, organics and biofertilizers proved significantly superior over all the other treatments in obtaining better growth and higher yield of groundnut was increased with the application of 100% RDN + 25% N through vermicompost + consortium (Rhizobium + PSB + KSB).
