“…In 2017, the total estimated production was over 21.5 million metric tons [ 6 ]. The state of Mexico is the second largest producer of maize, and also has the largest number of producers, 3.2 million, a high number considering that there are only 4 million in the entire country [ 7 ]. Traditional landraces of maize are still cultivated in small peasant holdings, using traditional rain-fed agrotechnology and usually multi-cropping systems known as “ milpa ” [ 8 ].…”

et al. 2018

In this research, quasi-spherical-shaped zinc oxide nanoparticles (ZnO NPs) were synthesized by a simple cost-competitive aqueous precipitation method. The engineered NPs were characterized using several validation methodologies: UV–Vis spectroscopy, diffuse reflection UV–Vis, spectrofluorometry, transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA), and Fourier transform infrared (FTIR) spectroscopy with attenuated total reflection (ATR). A procedure was established to coat a landrace of red maize using gelatinized maize starch. Each maize seed was treated with 0.16 mg ZnO NPs (~7.7 × 109 particles). The standard germination (SG) and accelerated aging (AA) tests indicated that ZnO NP-treated maize seeds presented better physiological quality (higher percentage of normal seedlings) and sanitary quality (lower percentage of seeds contaminated by microorganisms) as compared to controls. The application of ZnO NPs also improved seedling vigor, correlated to shoot length, shoot diameter, root length, and number of secondary roots. Furthermore, shoots and roots of the ZnO NP-treated maize seeds showed a marked increment in the main active FTIR band areas, most notably for the vibrations associated with peptide-protein, lipid, lignin, polysaccharide, hemicellulose, cellulose, and carbohydrate. From these results, it is concluded that ZnO NPs have potential for applications in peasant agriculture to improve the quality of small-scale farmers’ seeds and, as a result, preserve germplasm resources.

“…In the Atlacomulco district, which comprises the study region, in the 2020 agricultural cycle 147 412 ha maize, 398 ha husk tomato and 16 ha squash were cultivated (SIAP, 2020). Paulino-Flores et al (2017) recognize that the ecological dimension is the greatest strength of the small farmer plots in the region, and their weaknesses are the aspects of production and lack of organization for commercialization. Other unfavourable aspects are the loss of agrobiodiversity and the small areas for food production, which fluctuate between 0.4 and 1.1 ha, and up to 5 ha in a few cases (Paulino-Flores et al, 2017;Albino-Garduño et al, 2021).…”

The historical milpa has contributed to food security of small farmer families due to its biodiversity. The objective was to evaluate indicators of food access [basic food baskets (BFB), minimum wages (MW) and real food security index (RFSI)], Land Equivalent Ratio (LER), and maximum net income (NI) obtained from the polyculture of native maize-husk tomato-squash in two farm plots in the State of Mexico. The experiment was set up in San Pedro del Rosal (SPR) and San Juan Coajomulco (SJC), irrigated and rainfed, respectively, in the spring-summer cycle 2020. An experimental design in divided plots was used to evaluate two topological patterns: two rows of maize intercalated with one row of tomato and one of squash (MMTS) and one row of maize intercropped with one of husk tomato, one of maize and one of squash (MTMS). Five levels of fertilization with nitrogen, phosphorus and manure were tested. LER was evaluated with the yields of the three species in MMTS, MTMS and in monocropping at the same levels of inputs. BFB, MW, and RFSI were estimated using the regression equation that resulted in the maximum NI. In the two localities, the intercalated crops had higher LER than the monocrops. Comparing the two topological intercropping patterns, the maximum NI was obtained with MTMS in SJC and SPR (MXN $ 113 686.30 and MXN $ 204 649.70 ha-1 y-1). With the NI of the MTMS pattern in SJC and SPR, seven and 14 people, respectively, can be provided with BFB for a year. The highest daily MW were obtained with MTMS. In terms of land equivalent ratio, the highest LER were obtained with the MMTS pattern in SJC (2.78) and SPR (1.64). In economic terms, the better topological pattern is MTMS, and in function of LER, MMTS was better.

“…Nowadays, the concept of sustainable agriculture is increasingly gaining favour. The problem of maize sustainability is the theme of many research projects [Houshyar et al 2018, Paulino-Flores et al 2017, Vasileiadis et al 2017. Ehsan Houshyar et al [2018] evaluated the impact of nitrogen and water use management on the sustainability of maize production through energy analysis to assess sustainability in terms of resource consumption.…”

Miriam Paulino-Flores et al [2017] presented the sustainability assessment of hybrid and native maize production systems by applying the IDEA method (Indicateur de durabilite des exploitations agricoles), which in overall assessment takes agroecological, socio-territorial and economic criteria into account. Vasileios Vasileiadis et al [2017] used the DEXiPM model (DEXi Pest Management) for sustainability assessment in maize-based cropping systems considering the economic, environmental and social dimensions.…”

This study aims at the sustainability assessment of maize silage cultivation according to levels of nitrogen fertilization. Based on data provided by a field experiment, economic, production and environmental criteria were evaluated for three levels of nitrogen fertilization: 80, 120 and 160 kg/ha. The environmental impact of maize cultivation was evaluated by the Life Cycle Assessment (LCA) methodology. In a multi-criteria assessment, the weights of sub-criteria were evaluated on the basis of scientists, agricultural advisers and farmers’ responses through AHP methodology. Based on the mean opinion of the respondents, economic criteria have the greatest impact on overall sustainability evaluation (54%), while the impact of environmental criteria (30%) and production criteria (16%) is much smaller. Analysis of economic subcriteria proved to have the greatest impact of gross margin (61%) on sustainability assessment, followed by the economic efficiency index (31%), while the smallest impact (8%) was obtained for the economic independence index. Among the analysed production subcriteria, the level of production and complexity of agrotechnical operations (44% each) had the greatest impact on sustainability assessment, and the least – labour use (12%). The obtained results showed the best economic evaluation for 120 kg N/ha, while from a production and an environmental point of view the best alternative is the application of 80 kg N/ha. The overall evaluation, with estimated criteria weights, shows the best sustainability performance for an 80 kg/ha fertilization dose.
