英文摘要	-A great challenge of scientific research with carrot in semi-arid regions is obtaining the best productive characteristics and economic conditions by optimizing the green manure amounts using spontaneous species from the Caatinga biome, such as hairy woodrose (Merremia aegyptia L.) and roostertree (Calotropis procera Ait.). Therefore, this work aimed to agronomically and economically optimize the production of carrot roots in monocropping and of their components when fertilized with equitable biomass amounts of these spontaneous species in two cropping seasons in a semi-arid environment. The experimental design was a randomized complete block design, with five treatments and five replications. The treatments consisted of equitable amounts of hairy woodrose and roostertree biomass in amounts of 16, 29, 42, 55, and 68 t ha-1 on a dry basis. In each experiment, an additional carrot treatment without fertilizer (absolute control) was planted for comparison with the other treatments to determine maximum physical and economic efficiency. Carrot fertilization was performed with the incorporation of 48.87 t ha-1 of M. aegyptia and C. procera dry biomass into the soil to obtain the maximum optimized productive efficiency (commercial productivity). The maximum optimized agroeconomic efficiency (net income) of carrot cultivation was obtained when 49.64 t ha-1 of M. aegyptia and C. procera dry biomass was added to the soil. The use of biomass from these spontaneous species from the Caatinga biome as green manure is a viable technology for tuberose producers in monocropping in semi-arid environments.
