【 摘 要 】

Polycultures from broadleaves with tuberoses are being used in vegetable crop production systems in the semiarid region of Potiguar. The challenge is to determine whether these systems are productively viable when fertilized with organic matter produced by spontaneous species of the Caatinga biome. The objective of this study was to evaluate the agro-economic performance of arugula (A), carrot (C), and coriander (Co) polycultures fertilized with hairy woodrose biomass incorporated into the soil under different population densities among the component crops. The experimental design was a randomized complete block with four replications, with the treatments arranged in a 4 × 4 factorial scheme, from the combination of four amounts of hairy woodrose biomass incorporated into the soil (7.5, 15.0, 22.5, and 30.0 t ha-1 on a dry matter basis), with four population densities (20A-50C-20Co%, 30A-50C-30Co%, 40A-50C-40Co%, and 50A-50C-50Co% of the recommended population in the single crop). The efficiency of polycultures was evaluated through indexes and agro-economic indicators. The most productive agro-economic performance was obtained with a biomass of 18.21 t ha-1 of hairy woodrose incorporated in the soil and a population density of 50A-50C-50Co%.
