Since the beginning, Brazilian agriculture has been characterized as incipient, due to the
predatory lifestyle through irrefutable actions arising from man, the search for raw materials,
use of soil in an extractive way, safeguarding practices that are unfeasible for forage production
and consequently agricultural development . In this sense, the exacerbated growth of
inappropriate agricultural practices in Brazilian soils, in many ways intensifies soil degradation,
low fertility, not being different in the transition region of the Cerrado and Amazon biomes.
Thus, alternatives have been sought that aim at a more sustainable production model. Given the
facts, the objective of this work was to study agronomic attributes and soil health indicators in
an agroecological system cultivated with millet culture subjected to green manure in the
northern region of the State of Tocantins. The work was carried out on the premises of the
Center for Agricultural Sciences of the Federal University of Norte do Tocantins (CCA/UFNT)
located in the municipality of Araguaína - TO. The study was carried out through evaluations
of the agronomic characteristics of the millet crop intended for animal feed in an experimental
structure designed in randomized blocks with two treatments (species of gliricidia and
leucaena), a control without supply of organic fertilizer and four replications. Firstly, in the
experimental area, soil was collected for chemical characterization and correction according to
the results, followed by the harvesting of legumes that were cut, deposited and/or incorporated
into the soil. After a period of organic matter activity of around fifteen days, the millet culture
was sown for evaluations, regarding the agronomic characteristics such as height, number of
plants, stem diameter, panicle diameter, panicle length, length of between node, production per
area, stem/leaf/panicle ratio, among others. Also carrying out monitoring evaluations of the
biological, physical and chemical attributes of the soil during experimentation. With this, the
evolution of the soil microbiota was identified, as well as the humidity and respiration indexes
that are indispensable in the establishment of a culture. Fertilization with Gliricidia stood out
when related to the agronomic attributes of the crop, resulting in better results for most of the
evaluations, except percentage of panicle and dead matter.
