Field studies were conducted during rabi season of 2019-20 under All India Coordinated Sorghum Improvement Project (AICSIP) at Nandyal (Andhra Pradesh) to assess the impact of application of different form of biofertilizers on rabi grain sorghum. The experiment comprising of six treatments (T1: Recommended dose of fertilizer (RDF) alone, T2: RDF + seed treatment with Azospirillum (Azo.) @ 50g+PSB @ 50g/kg seed, T3: RDF + seed treatment with Azo. @ 2ml+PSB @ 2ml/kg seed, T4: RDF + seed treatment with Azo. @ 2ml + PSB @ 4ml/kg seed, T5: RDF + seed treatment with Azo. @ 4ml + PSB @ 2ml/kg seed and T6: RDF + seed treatment with Azo. @ 4ml + PSB @ 4ml/kg seed) were laid out in Randomized Block Design (RBD) with four replications. The results of the study revealed that seed treatment with Azospirillum and PSB fertilizers were promising to RDF alone from grain yield and net income point of view. Seed treatment with Azospirillum + PSB (2 ml + 4 ml/kg seed) in addition to RDF have enhanced grain and stover yields by 6.22 % and 1.52 % over RDF that together have improved net income by 18.9 %. Further with use of the above inoculants in liquid form (Azo. 2 ml + PSB @ 4 ml/kg seed) enhancing grain and stover yields by 12.45 % and 0.42 % over powder form of inoculants and have registered Rs. 8014 ha-1 higher net income. Liquid form of Azospirillum 2 ml + PSB 4 ml/kg seed have at par performance as that of Azo. 4 ml + PSB @ 4 ml/kg seed.
