Effect of a biostimulant on mango (Mangifera indica L.) production

Abstract

Objectives: evaluate the effect of the application of a biostimulant on mango (Mangifera indica L.) production. Methodology: The trial was carried out in Liberia, Costa Rica, in 2017. Engordone® biostimulant was applied to 18 trees of the Irwin variety, and this application was not carried out on another 18 trees (control treatment). At harvest, the fruits were classified as exportable, rejected or immature. The number of fruits per tree, the yield per tree (kg), the average weight of the fruit (g), and the length, width and thickness of the exportable fruit were evaluated. Results: There were no significant differences for the number of fruits per tree or the yield per tree. The fruits of the control treatment showed a higher average weight, compared to those that received the biostimulant. The exportable fruits of the control treatment had a width and thickness significantly greater than the exportable fruits of the biostimulant treatment. Conclusions: The application of the biostimulant caused a decrease in the average weight of the fruit, and in the width and thickness of the exportable mango fruits.
