Abstract:
This study aimed to assess the conjoint application of microbial consortium with 100% recommended dose of maize (200:80:80 kg ha^-1) fertilizers through drip irrigation on yield and uptake in alfisols at Regional Agricultural Research Station, Palem, PJTSAU, Telangana, India. The experiment was laid out in randomized block design with nine treatments replicated thrice, consisted combination of two factors i.e., 100 and 75% RDF with microbial consortium of nitrogen-fixing, phosphorus solubilizing, potassium releasing and zinc solubilizing bacteria. Results of the study revealed that the combination of 100% RDF of maize fertilizers (200:80:80 kg ha^-1) along with microbial consortium@ 1.5 L ha^-1 through drip irrigation up to 60 DAS register significantly higher pooled grain and stover yields as 7984 and 8933 kg ha^-1 respectively, compare to the conventional fertigation of 100% RDF in Alfisols. Total pooled uptake of NPK nutrients was significantly higher at fertigation with 100% RDF with biofertigation of microbial consortium@ 5 times (180, 90 and 185 kg ha^-1), compared to the other treatments consisting of microbial consortium with 100 or 75% RDF fertigation.
