A field experiment was conducted during kharif season of 2017-18 on sandy loam soil of S.V. Agricultural College Wetland Fam, Tirupati campus of Acharya N. G. Ranga Agricultural University to optimise the organic, inorganic and biofertiliser needs for sustained productivity of maize (Zea mays L.). Seven treatments comprising all possible combinations of chemical fertilizer, organic manure (vermicompost, FYM) with and without biofertilizer (Azospirillum and PSB) were laid out in randomized block design with three replications. Nutrient uptake and yield was significantly influenced by the application of organic and inorganic sources of nutrients. Application of 100 % RDF (T1) (180-60-50 kg N, P2O5 and K2O ha-1) recorded significantly higher nutrient uptake, kernel (5207 kg ha-1) and stover yield (6751 kg ha-1). However, 50% RDF + Vermicompost @ 1t ha-1 + Azospirillum @ 5 kg ha-1+ PSB @ 5 kg ha-1 (T7) has given a remarkable kernel (4683 kg ha-1) and stover yield (6394 kg ha-1) wand a higher nutrient uptake which is in turn in parity with 50% RDF + FYM@ 5 t ha-1 + Azospirillum @ 5 kg ha-1+ PSB @ 5 kg ha-1 (T6) and significantly superior to rest of the treatments.
