SUMMARY:

Brazil is among the world's largest producers of black pepper, with the states of Pará
and Espírito Santo being primarily responsible for cultivation and production. Black
pepper is cultivated mainly in countries with tropical and subtropical climates, finding
ideal conditions in the state of Pará. Black pepper is the most important spice
commercialized in the world and, as it is a commodity, the market trend is the
commercialization of products originating from sustainable production systems. The
use of a live Gliricidia Sepium L. tutor in the production system contributes to
sustainable production. However, the adoption of this technology is limited due to the
scarcity of information about the behavior of cultivars in this type of tutor, in addition
to the need to carry out studies on irrigation, management of pepper plantations and
nutrition to provide complementary knowledge for future adjustments and
establishment of a sustainable production system. Evaluating the issues addressed,
the study consists of identifying the appropriate irrigation and fertilization conditions in
which the black pepper culture cultivated in a live tutor has the water and nutritional
requirements met for production with quality and economic viability in the Northeast
of Pará. To assess the stability and expansion of the chain, production trajectories
were presented, based on a historical series from 1975-2020. For irrigated systems,
a lower water demand was observed with the use of Gliricidia sepium in the two-line
irrigation system. This lower implementation cost ensures financial resources for the
adoption of irrigation. When establishing the culture, reference is made to the
minimum fertilization levels, which are equivalent to the fertilization recommendation
in the literature. Regarding the quality (density, ether extract, piperine) of the black
pepper produced, there was an increase when using gliricidia, improving its quality.
The results of this study indicate a clear contribution of the use of a live gliricidia tutor
in the economic circularity of the black pepper chain. In this scenario, it is
recommended the establishment of public policies, aimed at the development and
validation of technological innovations that ensure increased productivity and
reduced risks in the black pepper production chain.
