Abstract

A field experiment entitled “Nutrient concentrations and their total uptake as affected by liquid bio-fertilizers in groundnut (Arachis hypogaea L.)" was conducted during kharif season of 2017 at research farm, COA, Gwalior on sandy clay loam soil to study the response of groundnut to chemical fertilizers and liquid bio-formulations. Four fertility levels viz., 25, 50, 75 and 100% RDF and three biofertilizer inoculation viz., no bio-formulations (B1), liquid Bio-NPK + Zn solubilizing bacteria (B2) and bio-grow (B3) to groundnut in 12 treatment combinations replicated thrice in split plot design. The yield and nutrient concentrations and their total uptake (N, P, K, Zn) was significantly highest with 100% RDF and liquid Bio-NPK + Zn solubilizing bacteria. However, their interaction had no significant influence on these parameters. But the highest values were observed when 100% RDF was applied in combination with liquid Bio-NPK + Zn solubilizing bacteria.
