Tridge summary

One study evaluated the productive performance of irrigated lettuce in single cultivation and intercropped with arugula and radish in agroforestry systems (SAFs) and in full sun. The objective was to find ways to improve the factors of production in the consortium crops of vegetables and green manures between the lines of an agroforestry system at the Embrapa Meio Ambiente Agroecological Site.

Agro-ecological and biodiverse agroforestry systems combine agricultural crops with forest and fruit trees in the same area, seeking the most efficient use of natural resources. The work was conducted by the Agroecology Center of Embrapa Meio Ambiente (SP), in partnership with the Federal University of São Carlos (UFSCar) and the Luiz de Queiroz Higher School of Agriculture (Esalq). The results showed that those cultivated in intercropping presented horizontal diameter, dry mass and number of leaves similar to those produced alone under the same conditions. Consortium systems are advantageous in comparison to single lettuce cultivation, as they produce a greater quantity of vegetables (arugula and radish) per unit of inputs and water. “Agroecological agroforestry systems (SAFs) present a combination of species of agricultural crops of economic interest and species with several other functions, including green manures, which are responsible for cycling and providing nutrients that ...
