Abstract
Field experiment was carried out at Hindustan Coca-Cola Beverages Pvt. Ltd.Bidadi Industrial Area, Bidadi Hobli, Ramanagar Taluk, during the year 2017-18 and simultaneously pot culture experiment was carried out under greenhouse condition in the
Department of soil science and Agricultural Chemistry, College of Agriculture, UAS, GKVK, Bengaluru. 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) however low in plant nutrients. In maize-cowpea cropping sequence among the treatments which received, RDF + gypsum + Irrigation with treated effluent from beverage industry recorded significantly higher kernel and
stover yield in maize (6932.56 and 8145.94 kg ha-1), seed and haulm yield of cowpea (1023.33 and 2411.86 kg ha-1) and in pot culture experiment kernel yield and stover yield(41.45 and 51.82 g pot-1) respectively, compared to other treatments. Soil properties like pH, EC and exchangeable Na were higher in treatment receiving RDF + Irrigation with treated effluent from beverage industry while, OC, available N, P2O5, K2O, secondary and micronutrients were higher in treatment receiving RDF + gypsum + Irrigation with treated effluent from beverage industry. Among the treatments, significantly lower kernel and stover yield in maize (5935.40 and 6974.26 kg ha-1), seed and haulm yield in cowpea (876.14 and 2064.95 kg ha-1) and in pot culture experiment kernel yield and stover yield(27.58 and 34.48 g pot-1) respectively, was recorded in treatment which received RDF + Irrigation with treated effluent from beverage industry. RDF + gypsum + irrigation with fresh water (0.302) recorded significantly higher harvest index compared to all other treatments. Higher benefit cost ratio were recorded in the treatment which received cycle of 1 irrigation with fresh water + 2 irrigations with beverage industry effluent + RDF + gypsum (2.42). Gypsum had shown significant effect in increasing the yield of the crop by reducing the effect of sodium on crop growth.
