This study aims to investigate the effect of fertilizers mixed with biofertilizers on maize crop micronutrient uptake. The study was conducted on clay loam soils at Agriculture College Farm, Bapatla, during both kharif 2020 and 2021. The results indicated that application of 100% RDF +VAM + Azospirillum + PSB recorded highest micronutrient content and lowest recorded with the control, but non-significantly influenced by the imposed treatments at kneehigh, tasseling and harvest stage (straw and grain) of maize crop. The application of 100% RDF +VAM + Azospirillum + PSB recorded significantly (P<0.05) highest iron, manganese, copper and zinc uptake at kneehigh, tasseling and harvest stage of maize crop. The results revealed that application of biofertilizers along with inorganic fertilizers significantly increased plant nutrient content and uptake of maize crop. In conclusion, the study suggested that integrated use of biofertilizers and inorganic fertilizers improves the nutrient content and uptake of maize crop.
