An investigation on “Studies on bioagents and consortium of bioagents (Biomix) in banana (Musa paradisiaca L.) Cv. Grand Naine” was conducted at Banana Research Station, Nanded, Taluka + District Nanded, Maharashtra, during year 2023-24. The field experiment was laid out in Randomized Block Design and replicated thrice. The experiment consists of eleven treatment combinations viz., T₁ - Bacillus subtillis, T₂ - Pseudomonas fluorescence, T₃ - PPFM (Pink pigmented facultative methylotropic), T₄ - Trichoderma viride, T₅ - Trichoderma herzianum, T₆ - Trichoderma virens, T₇ - Biomix, T₈ - Bacillus subtillis + Pseudomonas fluorescence + PPFM, T₉ - Trichoderma viride + Trichoderma herzianum + Trichoderma virens, T₁₀ - Bacillus subtillis + Pseudomonas fluorescence + PPFM + Trichoderma viride + Trichoderma herzianum + Trichoderma virens, T₁₁ – 100% RDF Control. The experiment framed was to study on bioagents and consortium of bioagents (Biomix) in banana (Musa paradisiaca L.) Cv. Grand Naine. Observations on growth attributes and yield attributes of individual treatments were recorded.

The results of present study indicated significant difference with respective growth, yield, quality and monetary returns among the different treatments tried. The growth attributes viz. maximum plant height (220.06 cm) was recorded by treatment T₁₀ - Bacillus subtillis + Pseudomonas fluorescence + PPFM + Trichoderma viride + Trichoderma herzianum + Trichoderma virens and plant girth (78.80 cm), number of leaves per plant (14.80 per plant) was recorded by treatment T₇ i.e., Biomix. The minimum values of plant height, plant girth, number of leaves per plant were recorded by treatment T₁₁ i.e., 100% RDF (Control). The yield parameters viz., maximum weight of bunch (24.27 kg) and yield per hectare (107.80 Mt/ha) was recorded by treatment T₇ - Biomix. While the minimum weight of bunch and yield per hectare was recorded by treatment T₁₁ i.e., 100% RDF (Control).
