Influence of organic manures and bio-stimulants on growth and herbage yield of Colocasia (Colocasia esculenta var antiquorum L. Schott)

The current investigation entitled effect of organic manures and bio-stimulants on growth attributes of colocasia (Colocasia esculenta var antiquorum L. Schott), was conducted at Dr. BSKKV, Dapoli during the kharif season in the year 2024. In the experiment there were eight treatments and three replications in Randomized Block Design (RBD). The experimental results depicted that the treatment T6 [FYM (30 t ha-1) + Seaweed Extract (3 ml L-1) + Humic Acid (1 ml L-1)] revealed significant superiority over other treatments in respect to the growth parameters viz., plant height (34.14 cm), leaf area (38896.57 mm2), number of leaves (10.27), leaf length (30.66 cm), leaf breadth (27.30 cm), petiole length (14.68 cm), leaf to petiole ratio (2.37), number of suckers per plant (5.57), herbage yield per plant (29.07 g plant-1), herbage yield per plot (0.93 kg plot-1), herbage yield per hectare (10.77 q ha-1). However, the treatment combination of FYM @ 30 t ha-1 along with Seaweed Extract @ 3 ml L-1 noted significantly at par results.
