Recipientes e densidades de cultivo na produção de coentro em ambiente protegido

Abstract

Coriander is a widely consumed crop in many countries. In Brazil, it is traditionally cultivated by small family farmers in the North and Northeast regions. Although the production of coriander occurs predominantly in the open field, cultivation in a protected environment can contribute to increase the productivity and quality of the crop, besides cooperating to reduce the seasonality of its supply. Based on the above, the objective of the present work was to investigate the agronomic performance of coriander cultivation in different containers and planting densities, under protected environment. The experiment was conducted in a screened nursery, in the Horta Didática of the UFC. A randomized complete block design was used, in a subdivided plot with four replicates. In the plots were evaluated plastic PVC containers that had different cell volumes (18, 31 and 100 cm³.cell-1). In the subplots, different seeding densities were evaluated (8, 10 and 12 plants.cell-1). The analyzed variables were aerial and root length, fresh and dry mass of shoot and root, productivity and visual aspect of shoot. The 100 cm³ container made it possible to obtain plants of higher height and fresh mass. The 31 cm³ container made it possible to obtain higher productivity, especially with a density of 12 plants per cell. The use of containers of 31 cm³ combined with the density of 12 plants per cell is the most suitable for the production of coriander in the conditions of accomplishment of this work.
