Abstract
A field experiment was conducted during Summer season 2022 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology And Sciences Prayagraj (U.P) to determine the “Influence of biofertilizers and organic liquid nutrients on growth, yield and economics of maize (Zea mays L.). The results showed that treatment 8 [Azotobacter (12.5 g/kg) + Azospirillum (12.5 g/kg) + Panchagavya (4%) recorded significantly higher plant height (172.43 cm), higher plant dry weight (135.93 g), maximum number of cobs/plant (1.53), maximum rows/cob (16.00), maximum seeds/row (26.76), higher seed index (24.83 g), higher seed yield (6.33 t/ha), higher stover yield (19.80 t/ha), maximum gross returns (144,420.60 INR/ha), maximum net returns (102,245.60 INR/ha) and highest benefit cost ratio (2.42) was also recorded in treatment 8 [ Azotobacter (12.5 g/kg) + Azospirillum (12.5 g/kg) + Panchagavya (4%)] as compared to other treatments.
