Crecimiento de plantas de vivero (musa AAB) con HMA en diferentes tipos de suelos.

Abstract

Worldwide, the banana has great economic and gastronomic importance. In Ecuador, bananas are grown mainly in the northeast area of the province of Manabí. In the soils destined for the cultivation of this musaceae, there is a great decrease in microorganisms, due to the contamination caused by chemical fertilization and the exaggerated use of herbicides, which also damage the adjacent environment. To improve the situation, in recent years there have been attempts to nourish crops with bio-fertilizers, which are friendly to the environment. For this reason, in the grounds of the "Río Suma" Experimental Farm in the city of El Carmen, a research work was carried out whose objective was to determine the interaction of arbuscular mycorrhizal fungi (AMF), in the growth of plantain seedlings (Musa AAB) inoculated with two types of AMF in the nursery phase. A Completely Randomized Block Design (DBCA) was used, with 5 treatments and 2 repetitions. Each treatment had 60 grams of AMF, except for the control treatment (T1), and 50 grams of NPK were added to treatments 4 and 5. There were no statistically significant differences in the variables studied. T2, with 60 grams of AMF in sterilized soil, obtained slightly better averages in the variables of plant height with 1.10m, in root weight with 239 grams, in leaf weight with 2.95 Kg, also in pseudostem weight. With 3.47 Kg, while T3 with 60 grams of AMF in concentrated soil had percentages of 13.27 and 67.08% in the available biomass and colonization rate variables, respectively.
