Abstract
An on farm trial was conducted to evaluate the effect of Biofertilisers and VAM on growth, yield & economics of Groundnut production. The experiment was laid out in Randomized block design with three treatment combination replicated seven times. The experiment was conducted during the Rabi season of 2019-20 at Narayanpur village under Baliapal block in Balasore district of Odisha. Seven number of farmers were included in this trial. The results of the experiment revealed that integrated application of N-P2O5-K2O @ 20:40:40kg/ha + Seed treatment with Rhizobium@ 50g/kg of seed + Soil application of PSB@ 5kg/ha &VAM@ 10kg/ha at sowing recorded significantly maximum growth & yield attributes resulting 25.4% higher pod yield than sole application of N-P2O5-K2O @ 20:40:40kg/ha.
