Efecto de tres abonos sobre el crecimiento y rendimiento en yuca (Manihot esculenta crantz) en Orellana, Ecuador.

Abstract

The objective of this experimental work was to assess the three fertilizers effect (compost, humus and humic acids) on the cassava crop (Manihot esculenta Crantz) by monitoring the plants and determine the best treatment, in "la Democracia" community, San Sebastian parish Province of Orellana. The methodology consisted of a completely randomized block design with a quantitative and qualitative approach, applying the descriptive method which begins with observation, register and analysis. Four treatments and three replications were used, focusing on plant height, stem diameter, length and diameter root, weight, yield in kg/ha and economic analysis. Their dosage was compost (30 g), humus (25 ml), humic acid (25 ml) and control. To analyze the effects of different treatments, comparative tests operated with an analysis of variance (ANOVA) using Tukey’s method with 5% significance level for confidence building intervals were applied using the IBM SPSS statistics 25.0 program. There was a significant difference with the results obtained, humic acid obtained a better plant height (106.43 cm), stem diameter (25.94 mm), root length (20.29 cm), weight (2.31 kg), yield (28.875 kg/ha) and finally had a similarity with the root diameter with the compost (4.29 mm), humic acid (4.32 mm) and humus (4.44 mm) treatments with statistically similar means. It was concluded the best treatment is humic acids that helped to stimulate plant enzymes and increase crop yield, i.e. it is recommended to use humic acids so that farmers in the amazon can use them in order to have better production with this variety of cassava for three months.
