This field experiment, conducted during the January 2020-February 2021 to investigate the impact of Sulphitated press mud cake (SPMC) in combination with Trichoderma viride, phosphorus solubilizing bacteria (PSB) and 100 % chemical fertilizer (RDF) on nutrient uptake and the productivity of sugarcane in calcareous soil in randomized block design (RBD).The highest germination (43.5%), number of tiller (170.55 × 10 -1 ha -1 ), plant height (272 cm), number of millable cane (NMC) (125.67 × 10 -1 ha -1 ), cane girth (2.20 cm) and single cane weight (0.831 kg) was observed in the plots receiving SPMC @ 12.5 t/ha along with T. viride + PSB.The addition of sulphitated press mud cake either with T. viride alone and in combination of PSB resulted in profitable yield of sugarcane crop.However, SPMC treatments (SPMC @ 5 -12.5 t ha -1 ) was found at par.The uptake of nutrients by sugarcane plant (NPK and micronutrients) significantly influenced due to application of either SPMC + T. viride or SPMC + T. viride + PSB.Furthermore, the nutrient uptake by sugarcane plants, including NPK (292.54,32.64, 278.55 Kg ha -1 ) and micronutrients viz.Fe, Mn, Zn, Cu (530.53,434.25, 454.12, 109.86 g ha -1 ) was significantly influenced by the application of SPMC, with the highest levels recorded in plots treated with SPMC at 12.5 t/ha along with T. viride and PSB.The integrated approach of SPMC, T. viride, and PSB presents a promising strategy for enhancing sugarcane productivity and nutrient uptake in calcareous soil.This research provides valuable insights for sustainable and highyielding sugarcane cultivation practices.
