| dc.description.abstract | A field experiment was conducted in a farmer’s field near M/s J P Distilleries Pvt. Ltd. Heggadathihalli village, Kunigal taluk, Tumkur district, during kharif 2013 to study effect of one time application of distillery spentwash R O reject on soil properties, growth and yield of maize (Zea mays L.) with seven treatments replicated thrice using RCBD design. The distillery spentwash (DSW) R O reject has pH of 7.29, high electrical conductivity (44 dSm-1), total dissolved solids (48000 mg L-1) and suspended solids (37100 mg L-1), high BOD (53560 mg L-1) and COD (87280 mg L-1). It contained nitrogen (1800 mg L-1), phosphorus (450 mg L-1) and potassium (11887 mg L-1) and also secondary and micronutrients in appreciable amounts. Among the treatments, application of 150% N through DSW R O reject recorded higher plant height (178.4 cm), number of leaves per plant (12.9), leaf area (766.9 cm2), number of rows per cob (16.7), number of grains per cob (564.7), test weight (25.8 g), grain yield (46.6 q ha-1) and stover yield (82.8 q ha-1) compared to all other treatments. Soil properties like pH (6.71), EC (0.55 dSm-1), OC (0.83%), available N (283.7 kg ha-1), P2O5 (24.1 kg ha-1), K2O (1213.5 kg ha-1), secondary and micronutrients recorded were higher in treatment receiving 150% N through DSW R O reject compared to all other treatments. Significantly lower grain yield (31.8 q ha-1), stover yield (58.8 q ha-1) of maize and soil properties were recorded in treatment receiving RDF only. | en_US |
