The use of biostimulants in plant production is an agricultural practice friendly to environment and one of the tools employed in the sustainable agriculture. The present paper was to determine the influence that the application of products based in oligosaccharines exerted on plant growth and development of garlic (Allium ampeloprasum L.) cv. 'Fredy'. The present work was performed, under field conditions, during the period October 2020 - February 2021 with the objective of determining the influence of the application of products based in oligosaccharines on the growth and development of elephant garlic plants (Allium ampeloprasum L.) cv. 'Fredy'. The effect of determined doses of QuitoMax® and PectiMorf® products, in different ways of application ("seed" imbibition, foliar spray at 80 DAP and the combination of both with the particularity was evaluated of also, combining the products) on the behavior of emergence percentage at 7 and 14 DAP. Besides, plant height (cm) and leaf number at 70, 90 and 110 DAP; as well as, the bulb characteristics and the survival percentage at harvest time was evaluated too. In addition, plant yield was estimated. Results shown that, in general, the application of QuitoMax® was more efficient than that of PectiMorf® in stimulating all the indicators evaluated, although the best results were obtained when both products were used in combination, that is, the "seed" imbibition with QuitoMax® and the foliar spray of the plants with PectiMorf® or viceversa.

The elephant garlic (Allium ampeloprasum L.) was introduced in Cuba, but it is not known who brought it. It is adapted to production and climatic conditions in the western part of the country, between October and February. With low inputs, it is resistant to diseases and reaches yields higher than 24.89 t ha-1 when planting is done mechanized and the "seed" is planted at 0.70 m of row, two rows and 0.07 m between plants, with which it reached between 15.10-15.0 t ha-1. This new garlic species has good post-harvest quality and adaptability in the areas studied. [ABSTRACT FROM AUTHOR]
