“…Piper and Boote [59] showed variation in protein and fat concentration in 20 soybean cultivars, with protein content significantly dependent only on cultivar, while fat content on cultivar and temperature related to latitude. Further, other authors proved significant effect of genotype on protein [54], fat [55,60,61], ash [61], and carbohydrate (raffinose and stachyose) contents [62]. The results presented in this study showed little anecdotal varietal variation in sugar content, which is consistent with the study of Alsajri et al [55].…”

“…Oil is important to the soybean industry because of its high use in edible oil production, but also as a source of a major renewable feedstock in biodiesel production. Under low temperature conditions, various authors have shown an increase in protein content and a decrease in fat content in soybean seeds [51][52][53][54][55][56]. In a study by Kołodziej and Pisulewska [49], an increase by 1 • C of minimal air temperature (13.4 • C) at the soybean flowering stage, resulted in an increase in fat yield by 7.7 kg•ha −1 , while the same increase in average daily temperature (19.9 • C) contributed to an increase in fat yield by 23.3 kg•ha −1 , with similar values of correlation coefficients (R = 0.916 and 0.922 respectively) and their level of significance (p = 0.01).…”

The objective of the study was to evaluate the effect of cold stress at flowering stage on plant structure, yield and chemical composition of seeds of 15 soybean cultivars. The study was conducted in 2019–2020, using the complete randomization method, in three replications. Fifteen soybean cultivars belonging to three maturity groups: early (EC), middle-early (MC) and late (LC) cultivars were included. Weekly cold stress (17/13 °C day/night) was applied at plant flowering stage. In the control treatment, plants were kept under natural conditions (24/17 °C day/night). Our research showed that cold stress negatively influenced the elements of plant structure: height, number of nodes, stem dry mass, number and weight of pods, number and weight of seeds per plant, as well as yield of soybean seeds, reducing it on average by 24%, as compared to the control treatment. The highest yield decrease was found in LC cultivars (31.2%), while a smaller and similar one in EC and MC cultivars (by 19.7 and 20.1%, respectively). Significant varietal differences were found for plant biometric traits and seed yield. EC cultivars had the lowest set first pod, as well as the lowest number of nodes, number of pods and seeds, pod and seed weight per plant, and seed yield. MC cultivars had the highest set first pod, and the smallest stem DM and seed yield average by 29.2% higher compared to EC cultivars. LC cultivars had the highest stem DM, number of pods and seeds, and pod and seed weight per plant compared to the other cultivar groups, and yield by 22.8% higher compared to EC cultivars. The experimental factors significantly affected crude protein, crude fat, and crude ash content, while they did not differentiate water-soluble carbohydrate and crude fiber content. Cold stress at the flowering stage caused a significant increase in protein content (by 4.1% on average) and ash content (by 3.8%) and a decrease in fat concentration (by 6.9%) in soybean seeds. Differences in nutrient content among cultivars were a genetic trait not related to cultivar maturity.

“…Pádua et al [14] reported that environmental conditions, and field weather (temperature, rainfall and relative humidity) influence the quality of seeds throughout the growing periods. According to Alsajri et al [17], the interaction between soybean cultivar and temperature influences soluble sugar (glucose, sucrose and raffinose family oligosaccharides (RFOs)) content of the seeds, but the sucrose and raffinose content declined when temperature increased. Soluble sugars are a vital seed constituent, for example, sucrose promotes seed filling, whereas RFOs may increase seed vigor under stressful environments [18].…”

The aim of the study was to determine the effect of seed production environment in Sri Lanka on seed development, maturation, and subsequent seed quality. The experiment was conducted at six production environments, three locations (Mahailluppalama (M1), Polonnaruwa (POL), and Aluttarama (ALU), over two planting cycles (P1, P2). Seed development and maturation, seed and seedling quality characteristics were evaluated at five reproductive (R6, R7, R8, R8 + 5 and R8 + 10) maturity stages. The study infers that production environment at the late reproductive (LR) stage (R6–R8) was critical in determining the seed quality. If the LR stage coincided with cumulative rainfall (RF) over 100 mm or above 75% relative humidity (RH), categorized as wet environment, around 27.5 days was required for the completion of seed maturation compared with only 17.5 days in dry environment. Seed lots from dry environment during LR stage surpassed the minimum quality standards (75% final germination, germination index of 300, germination rate index of 25% per day, seedling vigor index of 2500 and 15 µmol/min/mg FW catalase activity) at maturity stage R7 onwards, while this only occurred at maturity stage R8 for wet environment. A significant negative correlation (r = −0.50 **) was observed between glucose content, antioxidant enzyme activities and germination percentage. In conclusion, the findings provide useful information for the expansion of areas for seed production in Sri Lanka.

“…The minimum and maximum temperatures under baseline were below 20 °C and 31 °C, respectively. These values are within the optimal range for soybean growth (Vu et al, 2001;Alsajri et al, 2020), which reduced impacts of water deficit by the lower water demand (Jumrani and Bhatia, 2018;. However, the future climate projections indicate reduced rainfall and increased air temperature, potentiating yield losses in relation to the baseline under RCP 8.5 in 2041-2070.…”

Climate is one of the main limiting factors for agricultural productivity, where climate change may increase the risk for food production. Based on that, the aim of this study was to evaluate the impacts of climate change on rainfed and irrigated soybean yield in the MATOPIBA region, the new agricultural frontier in Brazil. The DSSAT CSM-CROPGRO-Soybean was used to simulate rainfed and irrigated yield using local soils, sowing dates, and maturity groups. The simulations included the baseline , and two future scenarios (2011-2040 and 2041-2070) for two representative concentration pathways (RCP 2.6 and 8.5). The future climate scenarios were obtained from global climate models (HadGEM2-ES and CSIRO mk3-6-0). The baseline showed a median yield of 3907 kg ha −1 across the region, a value that increased to 4006 kg ha −1 in the RCP 8.5 in 2011-2040. For the 2041-2070 period, RCPs 2.6 and 8.5 had a yield reduction to 3686 and 2388 kg ha −1 , respectively. The average yield reduction was higher than 23% under RCP 8.5 , reaching more than 53% in some areas. The yield impact in future climate scenarios was related to rainfall reduction by 300-400 mm cycle −1 , and temperature increased above 3 °C. The irrigation showed potential to offset negative climate change impacts, where yield gain was 2400 kg ha −1 under RCP 8.5. The future climate impact can be reduced by moving soybean crops preferentially to areas of higher altitude, with lower air temperature associated with irrigation. Further studies could explore potential adaptations related with physiological traits and crop management.
