“…This superiority of MER can also be attributed to the complementary nature of the cultures involved. These results corroborate those obtained by Lino et al (2021) studying the intercropping of beet and arugula under green manure and arugula planting densities in the semi-arid region of the Northeast, where they obtained a MER value of 1.56 with the combination of equitable biomass amounts of hairy woodrose and roostertree of 65 t/ha and of 1,000 thousand plants/ha of arugula, a result similar to that obtained in this research.…”

One of the biggest difficulties in the intercropping of radish-lettuce is to obtain the ideal dose of green manure and the adequate planting density for the crops. Therefore, the objective of the present work was to evaluate the agro-economic benefits of radish-lettuce intercropping under the influence of green manuring with Merremia aegyptia (hairy woodrose) and Calotropis procera (roostertree) and lettuce population densities in a semi-arid environment, in two cropping seasons. The experimental design used was randomized blocks, with treatments arranged in a 4x4 factorial scheme, with 4 replicates. The first factor in this scheme consisted of equitable biomass amounts of M. aegyptia and C. procera at doses of 20, 35, 50 and 65 t/ha on a dry basis, and the second factor of lettuce population densities of 150, 200, 250 and 300 thousand plants/ha. The production of radish and lettuce and its components, in addition to the agroeconomic indicators, system productivity index (SPI), land equivalent coefficient (LEC) and monetary equivalent ratio (MER) were evaluated. The greatest agro-economic benefits of the intercropped radish-lettuce were obtained with SPI of 15.37 t/ha, LEC of 1.27 and MER of 1.30, respectively, in the combination of 65 t/ha of M. aegyptia and C. procera biomass with the lettuce population density of 300 thousand plants/ha. The maximum commercial productivity of radish roots in the intercropping system was 8.45 t/ha in the combination of the biomass amount of 20 t/ha of M. aegyptia and C. procera and lettuce population density of 300 thousand plants/ha, while the maximum lettuce leaf productivity optimized in intercropping was 17.72 t/ha, in the combination of green manures biomass amount of 65 t/ha and population density of 300 thousand plants/ha of lettuce. The use of spontaneous species from the Caatinga biome as green manure in the radish-lettuce intercropping provides optimized agro-economic benefits in a semi-arid environment.

Given the lack of information on the use of spontaneous plants from the Caatinga biome as green manure to produce green grains, the present work aimed to agronomically and economically optimize cowpea production for green grains and their components when fertilized with equitable biomass amounts of hairy woodrose (Merremia aegyptia L.) and roostertree (Calotropis procera Ait.) in two cropping seasons in a semi-arid environment. The experiment used a randomized complete block design, with five treatments and five replicates. The treatments consisted of equitable amounts of dry M. aegyptia and C. procera biomass of 16, 29, 42, 55 and 68 t ha-1. In each experiment, an additional treatment was planted with cowpea without fertilizer (absolute control), and another was fertilized with mineral fertilizer for the purpose of comparison with the treatment of maximum physical or economic efficiency. The maximum optimized physical (agronomic) efficiencies of cowpea green pods and grain production were reached in the productivity of green pods at 3.90 t ha-1 and green grains at 4.06 t ha-1, with incorporation into the soil of 45.07 and 50.48 t ha-1 of green manure, respectively. The maximum economic efficiency of cowpea green grain production was reached at a net income of R$5826.12 ha-1 and at a rate of return of 1.29 reals for each real invested with application to the soil of 38.74 and 37.85 t ha-1 of the tested green manure biomass.

Radish and coriander are vegetables that complement each other when intercropped under organic fertilizer and the ideal density of the component crops. In view of this, this study aimed to evaluate the treatments, similar amounts of green manure and population densities of coriander in the biological parameters of the radish–coriander intercrop and determine the interaction between these treatments that provides the greatest economic return in a semi-arid environment. The experimental design used was randomized blocks, with treatments arranged in a 4 × 4 factorial scheme with four replications. The first factor consisted of Merremia aegyptia and Calotropis procera biomass amounts in the proportion of 50% for each green manure at doses of 20, 35, 50 and 65 t ha−1 on a dry basis. The second factor comprised four coriander population densities of 400, 600, 800 and 1000 thousand plants ha−1. The radish and coriander cultivars planted were ‘Crimson Gigante’ and ‘Verdão’, respectively. Significant agro-biological returns from this radish–coriander intercrop were obtained at a land equivalent ratio of 2.00, intercropping advantage of 11.39, canonical variable Z score of 2.45, radish aggressivity over coriander of 1.04, and actual yield loss of 2.15 with the incorporation of 65 t ha−1 of hairy woodrose and roostertree into the soil using a coriander population density of 1 million plants ha−1. The greatest economic return from radish–coriander intercropping (107,278.10 BRL ha−1) was achieved with the application of 25.88 t ha−1 of green manure biomass to the soil and a coriander population density of 1 million plants ha−1.
