The experiment evaluated the impact of various biostimulants on yield and fruit quality parameters of mango. Foliar spray of amino acid, Ascophyllum nodosum extract, and humic acid were tested in various concentrations. Results showed significant variations among treatments, for yield-related parameters, T₆ (Ascophyllum nodosum 3 ml/L) exhibited the highest fruit weight (263.21 g), number of harvested fruits (69.67), and yield per plant (18.34 kg). Fruit dimensions such as length, breadth, and volume were generally higher in treatments involving Ascophyllum nodosum compared to other treatments. In terms of biochemical composition, T₆ (Ascophyllum nodosum 3 ml/L) recorded the highest total sugar content (108.82%), indicating potential improvements in fruit maturity and sweetness. T₈ (Humic acid 2 ml/L) showed notable results in reducing sugar content (6.35%) and ascorbic acid content (55.97 mg/100g), suggesting enhanced nutritional quality. Overall, biostimulant treatments, particularly those involving Ascophyllum nodosum and higher concentrations of amino acids and humic acid, positively influenced both yield and fruit quality parameters of mango. These findings highlight the potential of biostimulants to enhance productivity and nutritional value, offering sustainable alternatives to conventional practices.
