“…This means that maize and soybean were grown in and restricted to different regions of the province. As a result, these two crops were not primarily cultivated together as anticipated, despite their well-known tendency to be planted together [26]. When looking at both crops, the 2006 to 2009 data (maps) indicate a growth in the area under soybean.…”

“…These crops were planted in different regions to mitigate yield reduction, given their differing competitive abilities. Additionally, separate management practices were implemented for each crop due to their distinct agricultural requirements, despite the occasional practice of planting them together or adjacent to one another [11,15,26]. Furthermore, soybean is predominantly utilized as a rotational crop with maize [5,10,11,15,26,27].…”

Land use practices face significant pressure due to increased demand and conflicting needs. Several factors contribute to this trend, such as the ever-increasing human population, the increased demand for food production, and the expansion of industrial and agricultural areas. This paper, focused on the cultivation patterns and investigating changes in land use of maize and soybean over time (i.e., both genetically modified and non-genetically modified) in two South African provinces. The objective was to determine whether there was a net increase or decrease in land cover age for these two crops between 2006 and 2017 in the selected study areas. Hence, the study utilized ArcGIS (10.8.1) software to quantify and map the land used for the cultivation of maize and soybean from 2006 to 2017 in Free State and North West provinces. The results show both provinces to have minimal expansion or change in cultivation areas for both maize and soybean between 2006 and 2017. We concluded that both maize and soybean cultivation areas in these provinces, did not expand beyond the current agricultural areas (space), and did not encroach onto new land areas. As a result, both maize and soybean do not currently pose a threat to the surrounding landscape (i.e., natural vegetation) and are not in direct competition with other neighboring land use practices. We recommend that data on the annual planting or cultivation area be consistently gathered, analyzed, and mapped to monitor any alterations that could influence the current findings. This will also assist with any land use planning and management practices.

“…This is a result of scientific and technological advances in the area (Cao et al, 2022). Soybean production, even with scientific and technological advances, still faces limitations such as water deficit, soil acidity, temperature, and solar radiation (Casali et al, 2022). In grain cultivation, soil fertility has been a major challenge, taking into account the macro-and micronutrients that define the biological processes in plants and responsible for crop productivity.…”

The soils of Brazilian Savannah are generally characterized by the predominance of highly weathered and acid Oxisols, with low fertility and high aluminum content, which inhibits the availability of phosphorus (P) for plants. Thus, we seek to develop technologies that minimize P losses. In this way, the objective was to evaluate the agronomic and economic feasibility of using the technology that reduces phosphorus adsorption reactions (TRRA) associated with single superphosphate (SS) in the cultivation of soybeans (Glycine max) in the 2018/2019 and 2019/2020 harvests. The experiment was carried out in the field, in a randomized block design, with four replications and a 4×2×2 factorial scheme, where doses of 320, 400, 480 and 570 kg ha−1 of SS were used, associated or not with the use of TRRA, in the 2018/2019 and 2019/2020 harvests. The components of yield, grain yield and economic feasibility were evaluated, calculating the operating cost and the point of maximum economic efficiency (PMEE). The PMEE in the 2018/2019 season occurred with the application of 568 kg ha−1 of SS and, in the 2019/2020 season, it was found with the application of 320 kg ha−1 of SS + TRRA. The best weather conditions in the 2019/2020 season (absence of prolonged water deficit) influenced productivity and improved TRRA efficiency. The economic analysis indicates that the use of TRRA increases the productivity of the soybean crop, generating greater net income for the producer. However, benefits may vary depending on weather conditions.This article is protected by copyright. All rights reserved

“…Traditional breeding is also currently used to promote the biofortification of carotenoids in maize [ 13 ]. However, few pigmented hybrids are commercially available in temperate [ 14 , 15 ] and subtropical regions [ 16 ]. White and yellow maize varieties adapted to tropical environments have already been selected for high nutraceutical and carotenoid concentrations [ 17 ].…”

Maize (Zea mays L.) represents the main caloric source for much of the world’s population. Pigmented maize varieties are an excellent source of nutraceutical compounds: blue and yellow maize are rich in anthocyanins as well as carotenoids and phenolic acids, respectively. However, blue maize is usually grown in small quantities as a specialty crop because it lacks the qualities and adaptations of commercial white and yellow varieties. Here, a new high-yield variety of blue maize called Vitamaiz was developed from inbred lines of subtropical blue, white, and yellow maize. The aim of this study was to characterize the nutraceutical and physical properties of 30 Vitamaiz hybrids in two subtropical locations. Kernel physical traits, nutrient composition, and nutraceutical components (free phenolic acids, FPA; cell wall-bound phenolic acids, BPA; total monomeric anthocyanin content, TAC; antioxidant capacity, AOX by oxygen radical absorbance capacity assay, and total carotenoid content, TCC) were evaluated. The biophysical traits of the hybrids were suitable for nixtamalized and flour maize industries. High levels of FPA (228 mg GAE/100 g), BPA (635 mg GAE/100 g), and AOX (2.0 and 8.1 mM Trolox equivalent/100 g for FPA and BPA, respectively) were also detected with elevated TAC levels (274 mg C3G/kg dw) and AOX activity (3.1 mM Trolox equivalent/100 g). This is the first study to characterize Blue × Yellow maize hybrids that adapt to subtropical environments.
