Response of stored INIAP 650 cassava stems to the application of biostimulants in Santa Ana, Manabí.
Main Article Content
Abstract
With the objective of evaluating the response of cassava (Manihot esculenta Crantz) to three storage periods and two biostimulants, an investigation was implemented in the Santa Ana canton of the Manabí province in a completely randomized block experimental design with a 3 x 3 factorial arrangement with three replications and nine treatments, corresponding to factor A: Biostimulants (A1: No biostimulants, A2: biol and A3: leachate) and factor B: Storage (B1: 30, B2: 60 and B3: 90) days. The variables evaluated were number of shoots, percentage of shoots, shoot height (cm), shoot diameter (cm), leaf length (cm), number of roots, root weight (g), root length (cm). The results showed that in the single and main effects the best biostimulant was leachate with an average of 14.26 (cm) for root length. In factor B (storage), the best time to store the cassava rods was 30 and 60 days. It is worth noting that at 30 days, an average of 9.89 was obtained for number of shoots, 98.89% percentage of shoots, 5.28 cm number of shoots, 18.39 (g) root weight, 12.46 (cm) root length. However, a strong interaction was observed between biostimulant factors and days of storage (30 and 60 days) for the variables shoot height, number of shoots, root length and root weight.
