Persistent nutrient depletion is posing a greater threat to the sustainable agriculture. Therefore, it becomes imperative to explore the most effective combination of inorganic fertilizers and liquid biofertilizers for sustaining the soil fertility and producing quality products. Hence, a field trial was conducted during kharif 2017 at College of Agriculture, Gwalior with a view to assess the effect of fertility levels and biofertilizers on quality and physiological parameters of groundnut. Experiment laid out as split plot comprised 12 treatment combinations replicated thrice in fixed plots having four fertility levels viz., 25, 50, 75 and 100% recommended rate of fertilizers as main plots and three bioformulations viz., no bio-formulations (B1), NPK liquid formulation + Zn solubilizing bacteria (B2) and bio-grow application (B3) as sub plots. Application of bioformulation as liquid NPK with Zn solublizing bacteria resulted in better physiological growth and highest kernel (2114 kg/ha) and haulm yield (6676 kg/ha) of groundnut crop. Same treatment also resulted in highest protein (4.4 kg/ha) and oil yield (6.7 kg/ha). Application of 100% RDF with bioformulation as NPK liquid formulation + Zn solubilizing bacteria produced highest LAI, CGR, RGR values as well as protein and oil yield of groundnut followed by 100% RDF with biogrow application.
