Abstract:
An experiment was conducted to evaluate the effect of various biostimulants during the primary hardening phase of tissue culture plantlets of Banana cv. Red Banana at the North Farm, School of Agricultural Sciences, Karunya Institute of Technology and Sciences, Coimbatore in the year 2022-2023. Among the various treatments, the maximum survival percentage (100%) during the primary hardening phase was observed in Soil + Cocopeat + Chitosan (50 ppm), Soil + Cocopeat + Chitosan (100 ppm), Soil + Cocopeat + Moringa leaf extract (3%), Soil + Cocopeat + Moringa leaf extract (4%), Soil+ Cocopeat + Vermiwash (3%), Soil + Cocopeat + Fermented coconut water. Among the various treatments given the maximum plant height (12.65 cm), pseudostem girth (4.12 cm), leaf length (7.51 cm), leaf width (4.27 cm), leaf area (25.70 cm2) and number of leaves per plant (4.75) was observed in Soil + Cocopeat + Moringa leaf extract (4%). The SPAD value was highest (38.24) in the treatment of Soil + Cocopeat + Chitosan (50 ppm).
