DESEMPENHO AGRONÔMICO DO COENTRO EM FUNÇÃO DA DENSIDADE DE SEMEADURA E DIRECIONAMENTO DAS LINHAS DE PLANTIO NO CANTEIRO

Abstract

The coriander (Coriandrum sativum L) is a hardwood vegetable of great commercial value in Brazil, among the producers of the northeast region the cultivar Verdão is widely exploited to produce green leaves. Although culture is of great importance, the scarcity of information about the production and commercialization of coriander is a problem. The experiment was conducted at the Center of Agricultural Sciences and Biodiversity (CCAB) of the Federal University of Cariri (UFCA), with the objective of evaluating the effect of the number of seeds planted and the orientation of the crop lines on the productivity of Verdão. The experimental design was a randomized block design with 4x2 factorial treatments, corresponding to four sowing densities (1, 2, 3, 4 g m-2 of seeds), and two orientations at the site (North-South, East-West) with three replicates. The following were evaluated: plant height; number of plants per square meter (NP), area fresh mass (MFPA); productivity and root mass per square meter (MFR). Statistical analysis of the data was performed using the SISVAR 5.3 program (FERREIRA, 2011). The results were submitted to analysis of variance and regression analysis. The variables that presented significant difference were evaluated by the Tukey test at 5%. The cultivation lines at the north-south plot were more advantageous to obtain plants with higher height and higher amount of MFPA, but showed no difference in the productivity of MFPA / m, however more studies are needed to clarify its effect on the increase of coriander productivity.
