ABSTRACT Lippia dulcis is a medicinal species used by communities in the Amazon region for the control of diabetes and as a tranquilizer. The objective of this study was to evaluate the plant biomass production, antioxidant defense, and chemical profiles of the phenolic compounds and essential oil of plants grown under different doses of cattle, quail, and chicken manure. Chicken and quail manure at a dose of 6 kg m-2 reached the highest values of dry weight and essential oil yield of the leaves and positively influenced bisabolol production. Cattle manure affected the content and yield of the essential oil of the inflorescences, the antioxidant defense performance, and the chemical composition of phenolic compounds and essential oil. Plants grown with cattle manure showed a linear increase in the amounts of these substances with increasing dose. Chicken and quail manure led to the highest values of these components at doses between 0 and 3 kg m-2. The evaluation of phenolic compounds and antioxidant defense showed the highest values at doses of 0, 1.5, and 3 kg m-2, regardless of the manure used. The essential oil concentration was higher in the inflorescences, and its total yield was higher in the leaves. The chemical composition varied between these vegetative organs. tranquilizer production m2 m 2 m- inflorescences performance m2. 2. 15 1 5 1.5 m2, 2, organs 1.

Resumen La hoja del jaborandi (Pilocarpus microphyllus) es la parte de la planta de interés económico de la cual se extrae la pilocarpina, por lo que la producción de hojas es la principal variable que determina la productividad de esa especie. La producción de hojas del Pilocarpus puede ser manejada por medio de la poda de sus ramas durante su fase de desarrollo. Con base en esto, el objetivo del trabajo es evaluar la regeneración de ramas de jaborandi sometidas a dos tipos de cortes y bajo sistemas de cultivos diferentes. En este experimento se realizaron podas en plantas de jaborandi, provenientes de diferentes accesos del Banco Activo de Germoplasma (Bag) de jaborandi, que estaban bajo diferentes sistemas de cultivos, a pleno sol y sombra. Con el auxilio de tijera de poda, se realizaron cortes a la altura de 10 y 20 cm de distancia de las bifurcaciones de las ramas en plantas de jaborandi. Los resultados mostraron que independiente de las distancias de los cortes realizados, las podas beneficiaron el surgimiento de nuevas brotaciones, logrando anticipar la cosecha e influir en la producción de hojas sin perjudicar el desarrollo de la planta. La poda drástica realizada en la especie Pilocarpus microphyllus estimula una regeneración eficiente sin dañar la planta proporcionando mayor producción de hojas independiente de la dirección de la poda realizada en el arbusto. Se observa que el cultivo del jaborandi se vuelve más productivo cuando se cultiva a pleno sol independiente del germoplasma utilizado y la cosecha de las hojas puede ser realizada durante todos los meses del año.

Abstract The leaf of the jaborandi (Pilocarpus microphyllus) is the part of the plant of economic interest, from which the pilocarpine is extracted, therefore, leaf production is the main variable that determines the productivity of this species. Pilocarpus leaf production can be managed during its development phase. Thus, the objective of the present study was to evaluate branch regeneration of jaborandi submitted to two types of cutting/pruning and different cropping systems. Prunings were carried out in jaborandi plants from different accessions from the Janorandi Active Germoplasm Bank (BGA), that were under different cropping systems, full sun and shade. With pruning shears, cuts were made 10 and 20 cm from the branch bifurcations. The results showed that regardless of the distances of the cuts in the jaborandi plants, the prunings benefited new shoots production and the harvest and influence on leaf production could be anticipated without harming the plant's development. The drastic pruning performed on the species also stimulated efficient regeneration without damaging the plant, resulting in bigger leaf production, regardless of the pruning direction. It was also observed that jaborandi cultivation becomes more productive when it is grown under full sun regardless of the germplasm used, and the leaves can be harvested in all the months of the year.
