“…Among the major problems faced in the last decades, environmental degradation has been highlighted, potentiated by some factors, such as high demand for food, use of chemical inputs for agricultural production and land misuse (Woolpert, 2015). It is known that with the exponential increase of the population and the increasingly scarce natural resources, producers have sought new techniques and sustainable alternatives to improve agricultural production and the production system as a whole (Silva et al, 2017).…”

The excessive use of agrochemicals in agriculture has been causing irreversible environmental impacts, from this point of view, organic farming appears as an economically viable alternative to minimize these impacts. So, the objective of this work was to evaluate the effect of different types organic fertilizers in the development and production of coriander harvested at different epochs. The experiment was conducted during the period from August to October 2016, in an area of the experimental farm of University of International Integration of Afro-Brazilian Lusophony. The experimental design was a randomized complete block design, in a 5 × 4 factorial scheme, consisting of five organic fertilizers and four harvesting epochs (28, 35, 42 and 49 days after planting-DAP) and five blocks. The variables stem diameter, plant height, root size, number of leaves, leaf length and productivity were evaluated. All the analyzed variables responded significantly by the F test, either for the qualitative factor, fertilizer sources, or the quantitative, epochs of evaluation. Regarding the cultivation epochs, when the first evaluation period (28 DAP) was compared with the last (49 DAP), it was verified that the variables presented linear responses over time, with increases of 34.4% for height , 29.5% for stem diameter, 37.07% for root length and 64.44% for production. In relation to the fertilizer sources, in general, the cattle manure provided a greater growth and production of the coriander plants, being therefore the most suitable for the cultivation.
