RESPONSE OF ‘BANILEJO’ MANGO TO FOLIAR APPLICATIONS OF A BIOSTIMULANT BASED ON FREE AMINO ACIDS AND POTASSIUM

Research was conducted to determine the effects of a biostimulant containing 5% free amino acids with 30% K₂O on marketable fruit number, average fruit weight and soluble solids concentration in fruit juice of ‘Banilejo 3’ mango.
The biostimulant rates used were 0 (check), 2, 4, and 6 ml of biostimulant formulation per L of water, applied to run-off on flowering trees and repeated three times at three week intervals.
The number of marketable fruits per tree increased with increasing biostimulant rate, up to approximately 19% at the rates of 4 and 6 ml/L. Average weight of marketable fruits also increased as biostimulant rates were higher, up to 16% at the biostimulant rates of 4 and 6 ml/L. The soluble solids concentration in the fruit juice was 19.5% in fruits from trees not treated with the biostimulant and approximately 22.5% in fruits from trees treated with the biostimulant rates of 4 and 6 ml/L. These results show that repeated sprays of formulations containing amino acid plus K₂O may be useful to increase marketable yield, average fruit size and soluble solids concentration in ‘Banilejo 3’ mango.
