SUMMARY:

Brazil is among the world's largest producers of black pepper, with the states of
Espírito Santo and Pará, places with ideal climatic conditions, being the main
responsible for cultivation and production. Black pepper is the most important spice
traded in the world and as it is a commodity, the market trend is to sell products
originating from sustainable production systems, with a relevant contribution from the
use of live tutor Gliricidia sepium L. replacing the estacão (dead stalk), in the
production of black pepper. However, the adoption of this technology is limited due to
the scarcity of information (irrigation, spacing, nutrition, management, among other
production factors) on the interactions between the behavior of black pepper cultivars
and this type of tutor, for consolidation of a sustainable production system. Therefore,
the study consists of identifying the appropriate irrigation and fertilization conditions in
which the black pepper crop grown in a live tutor has the water and nutritional
requirements met for production with quality and economic viability in the Northeast
of Pará. With the use of irrigation, there was a lower water demand with the use of
Gliricidia sepium in the two-line irrigation system, and lower cost. Implementation at
lower costs ensures financial resources for the adoption of irrigation. When
establishing the crop, the minimum fertilization levels must be adhered to, which are
equivalent to the fertilization recommendation in the literature. The quality of black
pepper produced with the use of gliricidia increased in relation to the parameters of
density, ether extract and piperine. The results of this study indicate evident
contributions of the use of 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, product quality and reduced risks in the black pepper
production chain.
