A field experiment was conducted in the premises of coca cola Pvt. Ltd., near Bidadi, Ramanagara district of Karnataka during 2017-18 to study the effect of beverage industry effluent on soil properties, growth and yield of maize with ten treatments replicated thrice using RCBD design. The beverage industry effluent was slightly alkaline in pH (8.21 ±0.20). Electrical conductivity was medium (1.75± 0.14 dS m^-1), BOD (5.23± 0.36 mg L^-1) and COD (20.44 ± 1.07 mg L^-1) and TSS (152.90 ± 0.21 mg L^-1) but low in plant nutrient content. Among the plant parameters in maize crop heigher plant height (207.44 cm), number of leaves (16.43), kernel and Stover yield (6818.25 kg ha^-1and 8011.63 kg ha^-1, respectively) were significantly higher in the treatment receiving irrigation with beverage industry effluent + RDF + gypsum (T₇) compared to all other treatments. Significantly lower plant height (177.61 cm), number of leaves (11.35), kernel and stover yield (6932.56 kg ha^-1 and 8145.94 kg ha^-1, respectively) were recorded in treatment received irrigation with beverage industry effluent + RDF without gypsum (T₂).
