Description
Summary:Plantain is an important crop for Ecuador due to its contribution in socio-economy and food security of this country, supplying rich-energy food to most of the population; in addition, it is necessary to carry out fertilization management that allows a better use of this resource and increase the yield. Magnesium fertilization in 'Barraganete' (Musa AAB) plantain was evaluated in El Carmen, Manabí, Ecuador. The research was conducted in the Experimental Farm "Rio Suma", Universidad Laica Eloy Alfaro de Manabí, Extension El Carmen, located at 260 masl, average temperature of 24 °C, annual rainfall of 2 684 mm. Six levels of MgO (0, 25, 50, 75, 100, 125 kg·ha-1) were applied to know its effect on morpho-physiology and plant yield. A completely randomized block design with six treatments and three replications was used; the sowing was carried out with a distance of 2.50 m x 1.80 m (2 222 plants ha-1), and the variables of vegetative growth were evaluated as repeated measures over time. The results demonstrated significant differences in all the morpho-physiological variables, which showed that fertilization with 30% MgO affected the growth of the plants; however, the reproductive variables were not affected by the applied doses; the 25 kg·ha-1 dose generated the best yields, agronomic efficiency and partial productivity factor.
