RESUMO:

Seasoning vegetables, also known as seasonings, have been important for a long time. They play an important role in the economy, health and cuisine. The Apiaceae family, Eryngium foetidum stands out among these spices. The plant can be found in different environments. The environment directly influences the plant. Changes in environments have a great impact, factors such as temperature, humidity, sunlight and others affect physiology, productive characteristics and quality. Furthermore, these factors influence functional compounds. It is important to understand the metabolism of the crop and how it interacts with the environment, being able to create a management system that helps produce leafy vegetables with the best attributes. The study aimed to verify the levels of chlorophylls, carotenoids, phenolic compounds, flavonoids, antioxidant activity and productivity. The experiment was carried out in Nova Mutum – MT, where pará chicory was cultivated, using randomized block methods, which included four repetitions and seven treatments. The treatments were six shading meshes, with 35% shade: black sombrite®, thermo-reflective silver aluminet®, red chromatinet®, pearl, organza (47 gm-2), white polyethylene agrotextile (TNT) (15 g m- ²) and open field. Agrotextile and organza stood out best for the cultivation of Eryngium foetidum, these treatments provided the best growth conditions, resulting in two harvests with greater leaf fresh mass, 106.8 and 155.9 g per plant. Through the application of the ABTS method, it was observed that the harvest carried out after 90 days is the most efficient, as it has the highest concentration of antioxidants and phytochemical compounds. One of the most favorable environments is agrotextiles, which have a high concentration of chlorophyll a and b. Furthermore, it was evident that open field cultivation has a positive impact on the quantity of phenolic compounds and flavonoids, which are directly related to the antioxidant capacity and quality of eryngium foetidum. Such factors are crucial to satisfy the demands of the consumer market.
