Efeito de diferentes doses de cama de aviário no Cultivo de coentro (Coriandrun sativum L.) na mesorregião do Baixo Amazonas - PA

Abstract

Fertilization with poultry litter is commonly used for the production of coriander, a vegetable widely consumed in the Baixo Amazonas mesoregion of Pará. The objective of this study was to recommend the most effective dose for improving the development of coriander. The experiment was conducted from July to August 2024 at the Federal University of Western Pará - UFOPA, Juruti campus. A completely randomized design (CRD) was employed, with 5 treatments and 6 replications, totaling 30 experimental units. The treatments consisted of a control and 4 doses (6, 12, 18, and 24 Mg ha1) incorporated into the soil in 5L pots. The variables evaluated included plant height (PH), root length (RL), number of leaves (NL), fresh weight of the aerial part (FWAP), fresh weight of the root (FWR), dry weight of the aerial part (DWAP), and dry weight of the root (DWR). Statistical analysis of the data was performed with the aid of the SISVAR software, and the results were subjected to analysis of variance, polynomial regression, and Tukey's test, all at a 5% probability level. Coriander showed better development at the dose of 18 Mg ha‍1, which resulted in the best productivity and viability outcomes for the crop.
