Produtividade de folhas, ramos e raízes de Chambá, Justicia pectoralis Jacq. em diferentes tipos de substratos

Abstract

Justicia pectoralis Jacq. is a plant that belongs to the Acanthaceae family and is popularly known in the Northeast as chambá. This work aimed to evaluate the production of leaves, branches and roots of chambá, Justicia pectoralis Jacq. On different types of substrates. The vegetative materials analyzed were obtained from a plant in full vegetative development, free from pests and diseases, cultivated in the greenhouse of the Medicinal and Phytotherapeutic Plants sector of the Agricultural Sciences Center – CECA/UFAL. The experiment was carried out in a randomized block design (DBC), consisting of 8 treatments and 7 replications. The substrates used were: T1- local soil (control); T2- composting; T3- sheep manure; T4- filter cake; T5- local soil (50%) + compost (50%); T6- local soil (50%) + filter cake (50%); T7- local soil (50%) + sheep manure (50%) and T8- local soil (50%) + compost (25%) + earthworm humus (25%). The variables analyzed were: fresh and dry matter of leaves, branches and roots. According to this study, it was possible to conclude that the substrate T4- Filter Pie was more efficient in the production of fresh matter from leaves and branches. Fresh roots had the highest average production when they were grown in substrate T8- Soil (50%) + Compost (25%) + Humus (25%). The T4-Filter Pie substrate was more efficient to produce the highest average dry matter of branches and roots. The dry leaves showed the highest production when they were cultivated in the substrate T5- Soil (50%) + Compost (50%).
