Uso de aserrín de balsa (Ochroma pyramidale) en la propagación de plátano (Musa AAB).

Abstract

The present research was carried out on the premises of the experimental farm “Río Suma” of the agricultural engineering program of the Laica Eloy Alfaro University of Manabí, El Carmen extension, with the objective of evaluating the effect of the use of raft sawdust substrate (Ochroma pyramidale) in the propagation of banana seedlings (Musa AAB) in greenhouse conditions, for this a Randomized Complete Block Design (DBCA) was implemented, in which five treatments were established with 4 repetitions for the treatments, doses were chosen of raft sawdust which were at (25%), (50%), (75%), (100%) with a control (0%) without the application of raft sawdust, for the development of the investigation they were chosen corms in excellent condition and were placed in the greenhouse for growth. The results found determined that for the variables days of sprouting, percentage of sprouting, pseudostem perimeter, number of leaves, number of roots that indicate the best range of significance, the dose of raft sawdust that had the greatest response was treatment T1 (25%) with a rapid sprouting of 7.75 days, presenting a sprouting percentage of 78.75, a pseudostem perimeter of 8.81 (cm), a number of leaves of 4.13 and roots 32.18. Unlike the T3 treatment (75%), the results found established that for the variables plant height, root weight and root length where it indicates the best range of significance, standing out with a height of 29.88 (cm) a weight of roots of 69.88 (g) and a root length of 41.48 (cm), the doses of (25%) and (75%) of balsa sawdust had better results with all the variables applied in the research.
