Abstract: An experiment was conducted to “Studies on use Soil amendments against Bakanae disease of rice (Oryza sativa L.)’’. The experiment was laid out in Randomized Block Design (RBD) with 6 treatment and replicated thrice. Study on disease severity of rice in field conditions revealed that the minimum disease intensity (31.15%) was obtained in T2 Trichoderma viride+ Pseudomonas fluorescens followed by T3 Trichoderma (50.87%), T4 Neem cake + Mustard cake (52.08%) and T6 Jeevamrit (55.71%), T5 Liquid Consortia (57.19%) and the highest was recorded in treatment T1 Control (72.18%). Among the treatments the plant height (cm) significantly increased in T2 Trichoderma viride+ Pseudomonas fluorescens (111.11cm) followed by T6 Jeevamrit (110.81cm), T3 Trichoderma (109.51cm), T4 Neem cake + Mustard cake (108.21cm) T5 Liquid Consortia (107.21cm) and the lowest was recorded in treatment T1 Control (103.02cm). The number of tillers/hill significantly highest in T2 Trichoderma viride+ Pseudomonas fluorescens (13.98a) followed by T6 Jeevamrit (13.58a), T5 Liquid Consortia (12.59b), T3 Trichoderma (12.10b), T4 Neem cake + Mustard cake (11.87b) and the lowest was recorded in treatment T1 Control (9.87c). The maximum numbers of tillers/hill was recorded in T2 Trichoderma viride+ Pseudomonas fluorescens (9.55a) followed by T6 Jeevamrit (8.75b), T5 Liquid Consortia (8.81b), T3 Trichoderma (7.88c), T4 Neem cake + Mustard cake (7.17d) and the minimum was recorded in treatment T1 Control (7.01d). The maximum numbers of tillers/hill was recorded in T2 Trichoderma viride+ Pseudomonas fluorescens (4.20a) followed by T6 Jeevamrit (3.62b), T5 Liquid Consortia (2.81c), T3 Trichoderma (2.62cd), T4 Neem cake + Mustard cake (2.34d) and the minimum was recorded in treatment T1 Control (1.57e). The maximum gross return (Rs. 166518 ha-1), net return (Rs. 132938 ha-1) and benefit cost ratio (1:3.96) was found in treatment T2 Trichoderma viride+ Pseudomonas fluorescens. Where as the minimum gross return (Rs. 67454 ha-1), net return (Rs. 34274 ha-1) and benefit cost ratio (1:1.02) was obtained in treatment T1 Control.
