Abstract

The maize is one of the main grains in Ecuador, of great
importance for indigenous peoples, who consider it a
generator of life. In the Amazon region, the Tusilla and Zhubay
varieties have been cultivated for many years, however, there
are no agronomic studies to determine a production model
for the region. Based on this, the objective of this work was
to evaluate the productive development of two varieties of
corn (Zea mays L.) with mineral and organic fertilization
under the conditions of the Ecuadorian Amazon. The research
was carried out in the Amazon Research, Postgraduate
and Conservation Center (CIPCA), in the Arosemena Tola
canton, Napo province for the Tusilla variety and in the
Ortiz Integral Farm located in the Sucúa canton, Morona
Santiago province for the Zhubay variety. In both experiments
a completely randomized block design was used with three
treatments (chemical, organic and control fertilization) and
four repetitions. Agricultural yield and yield components
were evaluated. Variance analysis and 5% Tukey mean test
were performed to determine the statistical difference between
the different variables. It is shown that the two local varieties
show a good production per plant of 97, 144 and 94 g plant-1 in
the Zhubay variety and 94, 138 and 89 g plant-1 in the Tusilla
variety according to treatments, chemical, organic and control
respectively. Likewise, the grain yield is very favorable for
local varieties in these conditions with values of 6.0; 9.0 and
5.8 Mg ha-1 in the Zhubay variety and 4.2; 5.7 and 3.7 Mg
ha-1 in the Tusilla variety. The Zhubay variety obtained better
performance in all indicators. In both cases, when organic
fertilizer is applied, better results are obtained in the evaluated
variables, which indicates the possibility of using local
varieties and organic fertilization in the production of corn in
the region without dependence on external inputs.
