One of the biggest challenges in intercropping of two or more crops is to maintain their productivity as that of their sole counterparts. In order to obtain sustainable intercropping systems in a semi-arid environment, this study evaluated the agro-economic advantage and sustainability of intercropped systems of carrot and cowpea, optimizing the green manuring and spatial arrangements. Experiments were conducted in the period from July to October 2017 and 2018, using a randomized complete block design with the treatments arranged in a 4 x 3 factorial scheme, with four replications. Treatments included four amounts of M. aegyptia incorporated into the soil (20, 35, 50, and 65 t ha-1 on dry basis) with three spatial arrangements (2:2, 3:3, and 4:4) between the components cultures formed from cowpea rows alternated with carrot rows. The agro-economic advantage indices evaluated in the intercropping systems were: land equivalent ratio (LER), area-time equivalent ratio (ATER), score of the canonical variable (Z), actual yield loss (AYL), intercropping advantage (IA), gross income (GI), net income (NI), rate of return (RR), and profit margin (PM). The highest agro-economic advantages of the carrot and cowpea intercropping were obtained for LER, ATER, NI, and RR of 2.60, 4.16, US$ 8,720.99 ha-1, and US$ 2.21, respectively, for M. aegyptia biomass amounts of 46.42, 47.82, 32.60 and 31.51t ha-1 added to the soil. The 2: 2 spatial arrangement was the one with the best productive performance, with higher net income and rate of return in the intercropping of carrot-cowpea.

“…Considering other cultures, Sousa et al (2018), studying the agro-economic performance of beet cultivated in association with cowpea under different doses of M. aegyptia, observed a higher performance at a dose of 55 t ha -1 of green manure added to the soil. This yield was 25.08% higher compared to that obtained with the lowest dose of 10 t ha -1 of green manure.…”

The introduction of new crops in northeastern Brazil, associated with the use of the green manure, can become an alternative for family farmers. Thus, the objective of this work was to determine the effect of green manuring with M. aegyptia L. on the agro-economic efficiency of radish production. The experimental design was a randomised complete block with four treatments and five replicates; the treatments were composed of four doses of M. aegyptia (20, 35, 50 and 65 t ha-1 on a dry basis) incorporated into the soil in three cropping periods. In radish plants, we evaluated plant height, fresh and dry mass of shoots, total and commercial productivity of roots, productivity of scrap roots, dry mass of roots and root diameter. The economic indicators gross income, net income, rate of return and profit margin were used to evaluate the agro-economic efficiency of the system. The maximum agronomic efficiency was reached with a commercial root productivity of 7.86 t ha-1 and the addition of 49.29 t ha-1 of green manure. The maximum economic efficiency was obtained with a net income of 11,955.46 R$ ha-1 when a green manure dose of 46.00 t ha-1 was added. The use of M. aegyptia as green manure is economically viable in the production of radish in the semi-arid region of Northeast Brazil.

“…For beet, the total area was 1.44 m 2 , with a harvest area of 0.80 m 2 . Cowpea was sown in the 0.50 m spacing between rows with 10 plants per linear meter, with a population density of 200,000 plants per hectare (COSTA et al, 2017), while beet was sown in a spacing of 0.20 m × 0.10 m, with a density of 500,000 plants per hectare (SOUSA et al, 2018).…”

The objective of this work was to evaluate the agro-bioeconomic feasibility of immature cowpea and beet cultivar combinations in intercropping systems in a semi-arid environment. Experiments were carried out in two cropping years using a randomized block design with four replicates. The treatments consisted of four cowpea cultivars (‘BRS Tumucumaque,’ ‘BRS Cauamé,’ ‘BRS Guariba,’ and ‘BRS Itaim’) and two beet cultivars (‘Early Wonder’ and ‘Fortuna’). In each block of the experiments, plots in monocropping of the cultivars were sown as additional treatments to obtain the following agronomic and competition indexes and economic indicators: land equivalent ratio (LER), area time equivalent ratio (ATER), land use efficiency (LUE), beet equivalent production (BEP), competitive ratio (CR), crop aggressivity (A), gross income (GI), net income (NI), rate of return (RR), and corrected monetary advantage (CMA). The highest agro-bioeconomic efficiency of the tested intercropping systems was achieved in the combination of cowpea cultivar BRS Guariba and beet cultivar Fortuna. Beet behaved as the dominant crop, and cowpea as the dominated crop in all evaluated intercropping systems. The indexes and indicators demonstrated the complementarity and sustainability of the combination of cowpea cultivar BRS Guariba with beet cultivar Fortuna.
