    Efecto de tres fuentes y tres dosis de potasio en el rendimiento de papa china, cultivar “blanca” [Colocasia esculenta (L.) schott] en la parroquia El Triunfo, provincia de Pastaza
    (2021-04) Pineda Morales, Noé Efraín; Leiva Mora, Michel
    The objective of this work was to determine the effect of sources and doses of K+ on the agricultural yield of Chinese potato, cultivar "white", because there is no history of similar studies in our country. During the experimental field phase at harvest time (210 days after planting, dpp) the following variables were evaluated: weight of cormels per plant, quality categories of cormels (first-class cormels 100 - 200 g, second 50 - 100 g and third less than 50 g), number of cormels per plant, weight of cormels per category and yield of cormels per hectare, benefit-cost ratio-1 (BC-1). All the sources of potassium increased agricultural yield, although the KNO3 fertilization source was the one that showed the greatest increase. When 99.6 g. plant-1 of KNO3 were applied, the highest quantity of cormels of C. esculenta cultivar “blanca” was obtained with first-rate quality. The fertilization treatment based on the application of 49.9 g. KCl's plant-1 was the one that generated the highest profit per dollar invested. However, in all treatments that used potassium sources, the profit was increased when compared to the control without fertilization. Profits ranged from US $ 0.3 to US $ 1.1 per every dollar invested.

    The research was carried out in the communities belonging to the Madre Tierra parish, Mera canton, Pastaza province, with the objective of obtaining important information regarding ancestral agricultural practices and knowledge that have been applied in yuca, banana and cane which are the most representative crops of the area. For the selection of the sample we visited different farms whose owners are colonizers of the parish or native of the same, who have knowledge about the three crops mentioned and above all have the desire to participate in the study. In this way, the participation and collaboration of 62 farmers were obtained, which were submitted to interviews which show all cultivation work. The results were described based on percentages and classified in groups first in characterization of the agricultural production units (UPAS); In which the age groups of the farmers are found, the level of education according to gender, with a high percentage of illiteracy in women, 25.6%, groups of farm areas and their correlation with areas cultivated with yuca, plantain and cane. Ancestral knowledge in precultural practices, standing out activities of preparation of the terrain as the rose, tumbe, repique, trasado, hoyado. Cultural practices involving selection of vegetative material, planting methods, fertilizer used, crops with which rotations and associations are carried out, pests and diseases. Ancestral knowledge in harvest and postharvest, medicinal uses. Ancestral knowledge in lunar cycles that involve taking into account the lunar phases for planting and weeding and finally ancestral knowledge in rituality highlighting a variety of planting rituals of yuca.
