“…Other factor of considerable relevance in the success of an intercropping system is the plant population, which directly influences the crops growing and development and system's productivity, through intraspecific and interspecific competition for environmental resources (Chaves et al, 2020). Studies on plant populations in crop associations are generally designed in part to improve system productivity and provide a rationalization of necessary crop treatments.…”

The triumph of the crops association with vegetables in semi-arid environment depends on crop types grown and adequate manipulation of treatment-factors tested such as fertilization, plant population, among others. Thus, this investigation aimed to valuate the bio-economic return of beet-rocket strip-intercropping in diverse balanced quantities of hairy woodrose (M. aegyptia) and roostertree (C. procera) biomass (20, 35, 50 and 65 t ha-1 on base dry) and in different rocket plant population (40, 60, 80 and 100% of that recommended population in monocropping - RPM), associated with the beet population of 100% of the RPM, in two years of cultivation. The bio-economic indices: land equivalent ratio (LER), intercropping advantage (IA), actual yield loss (AYL), productive efficiency index (PEI), canonical variable score (Z), gross return (GR) and net return (NR), rate of return (RR) and profit margin (PM) were assessed. The greatest bio-economic returns of beet-rocket strip-intercropping were of: 1.87; 7.44; 1.90; 0.98; 2.52; 85,827.79 and 65,425.01 R$ ha-1; 4.24 R$ for each real invested, and 77.02%, respectively, for LER, IA, AYL, PEI, Z, GR, NR, RR and PM in the biomass quantity of 65 t ha-1 of hairy woodrose and roostertree, in the rocket population of 100% of the RPM (a million plants ha-1). The hairy woodrose and roostertree biomass use from Caatinga biome proved to be a viable technology for growers who practice the cultivation of beet-rocket strip-intercropping in semi-arid environment.

“…In the intercropping systems, it is important to know the economic value of the system and the profit it can give producers. The monetary equivalent ratio is an indicator of economic feasibility of the intercropped systems and shows if they are advantageous (Chaves et al, 2020). In this study, monetary equivalent ratio values were higher than 1, evidencing monetary advantage of the intercrops coming from cowpea and beet cultivar combinations in relation to their best monocrops, indicating that the intercropped system with the best use of growth resources can translate into economic advantage.…”

“…This is probably related to the absence of interspecific competition over the natural resources of the environment. However, in intercropping cultivation, the presence of interspecific competition may, depending on the crops, decrease their respective productivities due to the high competition for soil nutrients and a decrease in the efficiency of plants to the available nutrients (Chaves et al, 2020). On the other hand, for cropping years within each cropping system, the first year stood out from the second one in the monocropping in the productivity of green pods, while the second one stood out from the first one in the intercropping (Table 1).…”

For the simultaneous achievement of productivity in beet and cowpea associations, it is necessary to take into consideration the choice of cultivar combinations that offer a response in terms of production, product quality and efficiency of the intercropping. Thus, the objective of this work was to evaluate the viability of production of beet cultivars combinations with cowpea cultivars in two cropping years (2016 and 2017) in a semi-arid environment. The treatments arranged in a 2 x 4 factorial scheme, with four replications, consisted of the combination of two beet cultivars (Early Wonder and Fortuna) with four cowpea cultivars (BRS Tumucumaque, BRS Cauamé, BRS Guariba and BRS Itaim), in addition to monocultures of these cultivars, as an additional treatment. The experimental design used was in randomized complete blocks. The production and its components were evaluated in the beet and cowpea. Apart from these characteristics, the following agro-economic indicators were also determined for each treatment: system productivity index (SPI), the land equivalent coefficient (LEC), and the monetary equivalent ratio (MER). The productive variables of cowpea and of the agro-economic indicators of the intercropping systems were higher in the second cropping year (2017), while the productive variables of beet were higher in the first cropping year (2016). The Early Wonder and Fortuna cultivars when in intercropping with the cowpea cultivars had similar commercial productivities of roots (11.29 and 11.93 t ha-1), respectively. The cowpea cultivar BRS Tumucumaque (1.38 t ha-1) was the most productive when intercropped with beet. The combinations of cultivars that had the highest agro-economic efficiencies and complementarity were those originated from the associations of BRS Tumucumaque (SPI = 18.43, LEC = 0.52 and MER = 1.42) and BRS Guariba (SPI = 18.42, LEC = 0.52 and MER = 1.48) with the Early Wonder beet cultivar.

“…Cowpea and radish are two companion crops of economic and nutritional value that can complement each other in an intercropping system because they have different plant architectures and root systems (Pereira et al, 2016;Chaves et al, 2020). Thus, an intercropping system between these crops has been recognized as a potentially beneficial system of agricultural production, as it increases the total yield of crops per unit of land per unit of time, as well as it increases the diversity of products, reduces the economic risks of the producer, and helps to efficiently and judiciously use the land, labor, and other environmental resources of the rural land (Nunes et al, 2018).…”

The objective of this work was to evaluate the agro-economic efficiency of immature cowpea-radish intercropping systems in a semiarid environment in Brazil. The experiments were carried out in two cropping seasons, in a randomized complete block design with four replicates. The treatments consisted of a 4x2 factorial arrangement for the combination of four cowpea (Vigna unguiculata) cultivars (BRS Tumucumaque, BRS Cauamé, BRS Guariba, and BRS Itaim) and two radish (Raphanus sativus) cultivars (Crimson Gigante and Zapp). The agro-economic indices - system productivity index (SPI), land equivalent coefficient (LEC), and monetary equivalent ratio (MER) - were obtained using single plots of each cultivar in each block. 'BRS Tumucumaque' and 'BRS Guariba' showed the highest productivity of immature cowpea pods, and 'Crimson Gigante' showed the highest yield of marketable radish roots. The cultivation of either 'BRS Tumucumaque' or 'BRS Guariba' cowpea with 'Crimson Gigante' radish provides a greater agro-economy efficiency and sustainability for immature cowpea-radish intercropping.
