This research aimed to evaluate the effect of organomineral fertilizer enriched with citric acid, on accumulation of dry matter content and phosphorus (P) in maize plants grown in greenhouse. A randomized block design with 6x3 factorial was used, combining six P sources (triple superphosphate, natural reactive phosphate of Bayóvar, superphosphate + poultry litter, Bayóvar phosphate + poultry litter, superphosphate + poultry litter + citric acid, Bayóvar phosphate + poultry litter + citric acid), three applied P levels (40, 80 and 120 kg ha-1 of P2O5), with four repetitions. The organomineral fertilizers produced with superphosphate provided higher accumulation of dry matter and P in shoots of maize plants than the organomineral fertilizers with Bayóvar phosphate. Plants that received the organomineral fertilizers with superphosphate presented higher accumulation of biomass and P in shoots than plants that received solely superphosphate, without effect of citric acid. The citric acid added to the organomineral fertilizer produced with natural reactive Bayóvar phosphate increased the accumulation of P in roots. The incorporation of organic matter to triple superphosphate increases maize growth and that the addition of citric acid to the organomineral fertilizers produced with natural phosphate increases the root growth.
