Influence of Commercial Seaweed Extract and Microbial Biostimulant on Growth, Yield, Phytochemical Content, and Nutritional Quality of Five Abelmoschus esculentus Genotypes

Biostimulant application during the cultivation of underutilized crops is an environmental-friendly approach for their production and utilization to promote food security human health. This study investigated effect two commercial biostimulants (a seaweed-based extract, Kelpak® (1:100, 1:40, 1:20, dilutions), plant growth promoting rhizobacteria, PGPR (1:5, 1:10, 1:15, dilutions)) on growth, yield, phytochemical content, nutritional quality five selected Abelmoschus esculentus genotypes. significantly influenced vegetative yield in a dose-dependent manner. Plant height, chlorophyll stem diameter, number pods, total pod fresh dry weights increased with decrease dilution biostimulants. The (1:5) promoted both (plant diameter) (number weight, weight) when compared control (untreated plants) other biostimulant dilutions. Genotype had interactive all (total phenolics, flavonoids, condensed tannins) (?-carotene, vitamin C, calcium, iron, potassium, magnesium, sodium, zinc) qualities evaluated. demonstrated differential A. These can be used enhance biochemical, contents underutilised such as esculentus, depending crop genotype, order improve productivity combat insecurity especially insecure communities.
