“…The economic indexes evaluated in the intercropping system were gross income (GI), determined by multiplying the value of production obtained per hectare by the price paid to the producer at the market level in the region in October 2016 and December 2017. The net income (NI) was calculated using the following expression: NI = GI -TC, where TC represents the total costs of the treatment (FERREIRA et al, 2022). The rate of return (RR) was obtained by the ratio between gross income and total costs (RR = GI / TC).…”

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.

The postharvest quality and coloration of radish roots can be compromised by factors such as the type of cropping system and fertilization management. Therefore, the objective of this work was to estimate the postharvest quality indices and color parameters of radish roots in monocropping, as a function of different roostertree (Calotropis procera) biomass amounts, in two cropping seasons in a semi-arid environment. The experimental design used was randomized complete blocks with five treatments and five replications. The treatments consisted of different roostertree biomass amounts: 16, 29, 42, 55 and 68 t ha-1 on a dry basis, incorporated into the soil. In each block, two additional treatments were added, one without fertilization (control) and the other with mineral fertilizer, for comparison purposes with the maximum efficiency treatment. The radish cultivar planted was Crimson Gigante. The radish characteristics evaluated were: pH, soluble solids content (SS), titratable acidity (TA), SS/TA ratio, total soluble sugar content (TSS), vitamin C (CV) and anthocyanin (A) contents, and roots color parameters (L*, C* and h°). The maximum flavor efficiency (SS/TA) and the total soluble sugar content (TSS) were achieved with the incorporation into the soil of 47.24 and 25.27 t ha-1 roostertree biomass, respectively. Higher concentrations of bioactive compounds (CV and A) were obtained when incorporating 35.79 and 45.85 t ha-1 green manure biomass. The color parameters values (L*, C* and h°) in the red radish roots were achieved in the biomass amounts of 40.39, 53.14 and 52.71 t ha-1 of roostertree.

The use of spontaneous species from the Caatinga biome as green manure is a promising practice in increasing the productivity of agricultural systems and sustainable exploitation of the environment. This study aimed to estimate the maximum physical and economic efficiencies of radish agroeconomic characteristics in monocropping as a function of roostertree (Calotropis procera (Ait.) R. Br) biomass amounts in two cropping seasons in a semi-arid environment. The experimental design was randomized complete blocks with five treatments and five replications. The treatments consisted of different roostertree biomass amounts: 16, 29, 42, 55, and 68 t ha-1 on a dry basis, incorporated into the soil. In each block, two additional treatments were added, one without fertilization (control) and the other with mineral fertilizer, for comparison purposes with the maximum efficiency treatment. The radish cultivar planted was ‘Crimson Gigante’. The fertilization of the radish to obtain the maximum optimized productive efficiency (9.56 t ha-1) was possible with the incorporation of 50.86 t ha-1 of C. procera dry biomass into the soil. The maximum optimized agroeconomic efficiency (based on a net income of 37,641.08 R$ ha-1) of radish cultivation was obtained with 44.39 t ha-1 of C. procera dry biomass added to the soil. The rate of return and the profit margin obtained were 2.94 R$ for each real invested, with a profit margin of 62.55%. The use of biomass from the C. procera green manure is a viable technology for producers who practice radish monoculture in a semi-arid environment.
