Agregar Etiqueta | Sumario: | The main objective of this research work was to evaluate the effect of biochar on the soil for growth and production in the cultivation of pearl onion (Allium cepa L.), in the Bolívar canton of the Manabí province. The experiment was carried out for a period of 90 days and the sowing was done in containers (pots), a complete random design (DCA) was used,) with a factorial arrangement A x B with 15 treatments, four replicates and 60 experimental units. The evaluated doses were five (0% p/p, 1% p/p, 1.5% p/p, 3% p/p, 5% p/p). The recorded variables were: plant height (cm), number of leaves, pseudostem diameter (cm), root length (cm), bulb fresh weight, bulb dry weight, root dry weight, leaf dry weight, bulb diameter (cm) at 30, 60 and 90 days after sowing. The data were subjected to analysis of variance (ANOVA) and the separation of means with Tukey's test at 5% probability of error. The results showed that the biochar based on peanut shells had a significant difference in plant height and diameter, with different concentration levels, while the biochar based on rice presented differences in weight in the same way at different concentrations, in relation to with the witness. |
