“…Bezerra Neto et al ( 2019), using C. procera in the fertilization of carrot and cowpea intercropping, obtained a productivity of 17.31 t ha -1 and 1.29 t ha -1 for carrot and cowpea beans, respectively, by using 48.05 and 45.51 t ha -1 of C. procera, respectively. In turn, Silva et al (2020), also working with carrot and cowpea intercropping fertilized with M. aegyptia, obtained a productivity of commercial roots of 29.47 t ha -1 and productivity of green grains of 3.13 t ha -1 using 32.69 and 50.17 t ha -1 of M. aegyptia, respectively.…”

Green manuring with spontaneous species from Caatinga biome has become an important strategy in production vegetables. One of the great challenges in tuberous vegetables production is to define an optimized quantity that provides a high productive yield with economic efficiency of production system. The objective of this study was to optimize agronomically and economically the production and its components of tuberous crops of beetroot and radish when manured with different amounts of green manures biomass, Merremia aegyptia and Calotropis procera from Caatinga biome, in two cropping seasons. The experimental design was a randomized complete block with five treatments and five replications. Treatments consisted of green manures amounts (16, 26, 36, 46, 56 t ha-1). The maximum agronomic efficiency of beetroot and radish was obtained with incorporation of 49.87 and 39.43 t ha-1 of M. aegyptia and C. procera, respectively, and the production maximum economic efficiency was reached when 36.14 and 36.48 t ha-1, respectively, of biomass of these green manures were added to the soil. The returns rate obtained in beetroot and radish cultivation using the manures optimized amounts were 1.42 and 1.32 reais obtained for each real invested in the production of these tuberous.

“…The use of green manuring has been one of the management practices used in organic cultivation and production of crops, including vegetables. According to Silva et al (2020), green manure incorporates plant biomass, produced in the place of origin or not, to increase the levels of organic matter and nutrients in the soil, in addition to improving the structure, aeration, and water storage capacity in the soil, contributing to the improvement of physical properties, chemical and biological aspects of the soil. The choice of plants to meet these requirements depends on the potential for phytomass production and the ability to absorb and accumulate nutrients.…”

Green manuring with spontaneous species from the Caatinga has emerged as a viable alternative to supply vegetables with nutrients and thus increase their productivity. This study aimed to evaluate and estimate the maximum physical and economic efficiencies of coriander productive characteristics as a function of equitable biomass amounts of hairy woodrose [Merremia aegyptia (L.) Urban] and roostertree [Calotropis procera (Aiton) W. T.] in different cropping seasons. The experimental design was a randomized complete block with five treatments and five replicates. The treatments consisted of green manure amounts (16, 29, 42, 55, and 68 t ha-1 on a dry basis). A treatment without fertilization (control) was used in each experiment. The maximum agronomic efficiency (coriander green mass yield) was possible with the incorporation of equitable amounts of 49.56 t ha-1 of M. aegyptia and C. procera biomass, respectively. The maximum economic efficiency of production (evaluated in terms of net income and rate of return) of this leafy vegetable was achieved with the addition to the soil of 42.68 and 41.64 t ha-1 of biomass of these green manures, respectively. The net income and the rate of return optimized for these amounts of green manures were 30,243.92 R$ ha-1 and 2.79 reais for each real invested in the production of this leafy vegetable. The use of biomass from Merremia aegyptia and Calotropis procera from the Caatinga biome proved to be a viable technology for producers who practice the cultivation of coriander when monocropping in a semiarid environment.
