Si, primarily absorbed by plants in the form of orthosilicic acid, demonstrates a diverse range of roles in enhancing plant resistance to environmental stresses. Biotic stresses, including pathogen attacks and insect infestations, are notably mitigated by the deposition of Si in plant tissues, fortifying cell walls and triggering defence mechanisms. Furthermore, Si plays a crucial role in alleviating abiotic stresses such as drought, salinity and metal toxicity, imparting resilience to plants in challenging environments. The interaction between Si and plant physiology involves intricate mechanisms, impacting nutrient uptake, photosynthesis and hormonal regulation. As research in this field advances, a comprehensive understanding of the nuanced effects of Si on plants emerges, paving the way for innovative agricultural practices and the development of stress-resistant crop varieties.

However, specific combinations of these approaches are often untested for optimality. Here, we explore the effects of two maize planting practices (ridge sowing and mulching) to conserve water, in combination with foliar thiourea. Drought stress response of crop was assessed at two experimental sites (L-I and L-II), through split-plot design (main plots: flat sowing + mulch, flat sowing, ridge sowing + mulch [RS + M] and ridge sowing; sub-plots: unsprayed, water spray, 500 ppm thiourea and 1000 ppm thiourea). Plant performance was assessed via dry matter accumulation, grain growth rate, stomatal parameters, grain yield, stover yield and nitrogen uptake. Rainfall breaks induced three dry spells during the pre-anthesis and grain-filling period. RS + M showed maximum drought tolerance by enhancing rainwater and nutrient use (N uptake [88.1 and 115.1 kg ha<sup>−1</sup>]) and recorded significantly higher periodic dry matter accumulation (149.2 and 156.8 g) along with higher 1000-grain weight (181.0 and 196.6 g), grain-filling duration (36.3 and 34.9 days) and leaf health parameters over the flat-sown treatments. Furthermore, foliar supplementation of thiourea at 1000 ppm caused improved leaf health, likely through activation of a source to sink response (transfer of energy and materials from leaves to other plant organs) that alleviated moisture stress.

Two field experiments (E1 and E2) were conducted in the Argentinean Pampas during two growing seasons to evaluate a WC/late-maize-wheat sequence under no-tillage. In each experiment, late-maize was sown after a bare-fallow and three WC: wheat, vetch (<i>Vicia villosa</i> L.) and field pea (<i>Pisum sativum</i> L.), where five rates of N fertilisation were evaluated. An area of late-maize that was not fertilised with N within each previous WC was used to evaluate the response to N fertilisation in the subsequent wheat crop. Indigenous N was estimated by using N uptake in the non-N-fertilised treatments. Soil N indicators and C:N ratio of WC residues were evaluated as indicators of response to N fertilisation in both crops. Significant responses to N fertilisation in grain yield and N uptake were observed in late-maize when bare-fallow and wheat were the previous treatments in both experiments. In contrast, vetch and field pea supplied 32 and 40 kg N ha<sup>−1</sup> in E1 and E2, respectively, and showed no response to N fertilisation, satisfying the N required by late-maize. However, this supply was not enough to sustain the N demand of the subsequent wheat, where the response to N addition ranged from 36% to 74% when vetch and wheat were the previous WC, respectively. Only soil inorganic N indicators were associated with indigenous N supply. Moreover, the apparent net WC effect was linked to late-maize (<i>r</i><sup>2</sup> = 0.91) and subsequent wheat (<i>r</i><sup>2</sup> = 0.67) grain yield response, which was also related to the C:N ratio of the WC residues in late-maize and the subsequent wheat (<i>r</i><sup>2</sup> = 0.78), suggesting that mineralisation occurs when C:N ratio is below 18.

Understanding the trends and magnitude of grain-based metabolites is vital for selecting wheat genotypes with higher grain yield, drought tolerance, water use efficiency and product profiles. The aim of this study was to determine the response of newly developed wheat genotypes for grain yield and component traits and metabolites under drought stress to guide selection. One hundred wheat genotypes were preliminarily evaluated for agro-morphological traits and water use efficiency under drought-stressed and non-stressed conditions during the 2022 and 2023 growing seasons using a 5 × 20 alpha lattice design with two replications. Ten high-yielding genotypes were selected based on grain yield and were validated for agronomic traits and water use efficiency (WUE), and grain samples were assayed to profile their key metabolites under drought-stressed conditions. Significant differences existed (<i>p</i> &lt; 0.05) among the tested wheat genotypes for yield and yield components, WUE, drought tolerance and major metabolites to discern trait associations. The grain yield of the 10 genotypes ranged from 590.00 g m<sup>−2</sup> (genotype LM70 × BW140) to 800.00 g m<sup>−2</sup> (BW141 × LM71) under drought-stressed treatment, whilst under non-stressed it ranged from 760.06 g m <sup>−2</sup> (LM70 × BW140) to 908.33 g m<sup>−2</sup> (LM71 × BW162).

Waterlogging leads to significant yield losses in sensitive crops, such as soybean (<i>Glycine max</i> [L.] Merr.). Identifying soybean genotypes and traits associated with better waterlogging tolerance is of high interest. We assessed the response of six soybean genotypes, selected from a field screening of over 190 genotypes, to 10 days of waterlogging at the R1 (onset of flowering) and R4 (grain filling) stages. We evaluated yield and its components, as well as shoot and root dry weights (DW) at the end of the waterlogging treatments and at maturity, along with morphological traits such as plant branch number, stem diameter and plant height. By integrating all these traits, a waterlogging tolerance index (WTI) was calculated for each genotype to rank their sensitivity. The WTI showed variations among genotypes from 0.61 to 0.77, indicating genotypic variation in response to waterlogging. Greater reductions in root DW compared to shoot DW were observed immediately after waterlogging. By maturity, shoot DW of waterlogged plants was more severely reduced than root DW in all genotypes. Despite similar DW losses at R1 and R4 at physiological maturity, seed number per plant and 100-seed weight responses differed between the treatments. Genotypes that performed well under control conditions suffered significant yield reductions of 70%–85% after waterlogging, mainly due to fewer fertile nodes and seeds per pod, with some also experiencing a notable decrease in 100-seed weight. In contrast, other genotypes had milder responses, with less severe reductions in seed and pod traits.

The aim of this study focuses on determining the effects of the moment and duration of waterlogging stress on the yield and its components in sunflower, soybean and sorghum. This information will be useful to understand the effects of waterlogging on yield and to choose a suitable crop or sowing date based on predicted weather conditions for a certain place. To achieve this objective, four experiments were conducted at the Experimental Station of INTA (Reconquista, Santa Fe, Argentina). The effect of the waterlogging in terms of moment (vegetative, critical and grain-filling periods) and duration (3, 7 and 10 days) on the three crops was evaluated. Sunflower expressed the most negative impact of waterlogging during the vegetative stages (26, 78 and 98% of yield losses with 3, 7 and 10 days, respectively) while soybean suffered major reductions when the stress occurred during the critical period (5%–17% of yield loses). Sorghum did not express any negative responses for the moments and durations tested.

The purpose of this experiment is to use Root Zone Water Quality Model (RZWQM2) to study actual transpiration (AT) and evaporation (AE) under different irrigation schedules and then determine its impact on grain yield and CWP. In the 2019–2022 winter wheat growing seasons, four experimental treatments were set up: no irrigation during growth period (I0), irrigation at jointing stage (I1), irrigation at jointing and anthesis stage (I2) and irrigation at jointing, anthesis and filling stage (I3), and the RZWQM2 model was calibrated and verified in this experiment. A higher yield (7840.90 kg/ha for an average of 3 years) and the highest CWP can be obtained in I2 treatment (increased by 12.72%, 5.98% and 4.28% for an average of 3 years, respectively, compared to the other three treatments). The model has a good simulation effect on soil water dynamic change and plant physiological performance of the four treatments; the model showed that irrigation increased the simulated AE and AT; however, reduced AE/actual evapotranspiration.

Thus, I3 increased AT at the late growth stage of winter wheat and resulted in an increase in grain yield; however, it did not significantly increase CWP.

Moreover, the responses to shade varied among soybean cultivars, with certain genotypes demonstrating distinct tolerance levels, which allowed also the estimative of genetic variance that revealed strong participation of genetic components in responses to shade. Multivariate and clustering analysis using steam diameter and plant height in combination with two yield components resulted in the identification of four soybean cultivars more tolerant to shade environments and two sensible. Therefore, this report provides insights into soybean cultivation under varying light conditions, provides a robust foundation for the integration of morphological and yield markers in breeding programmes focused on shade tolerance and guides future endeavours in crop improvement for optimal and sustainable yield and resilience in the climate change context.</p>\u0000 </div>","PeriodicalId":14864,"journal":{"name":"Journal of Agronomy and Crop Science","volume":null,"pages":null},"PeriodicalIF":3.7,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142234982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Concerns about agriculture continue to be a recalcitrant obstacle in the path of upward movement. Although agricultural yields are increased, however, low- and middle-income countries still have difficulty in producing all of the required foods with the current state of agricultural technology. Smart agriculture is becoming increasingly important to the farmers as a means of ensuring optimal field growth and higher crop yield. This systematic study analysed and briefly explained the effects of using smart agriculture techniques (SATs) from a variety of countries, including China, the United States of America, Australia, India, the Philippine Islands, South Africa, Pakistan and Iran, among others. Increased climatic change resulting in abiotic stress and other harmful effects on plants have resulted in decreased productivity under traditional agricultural practices. Stats from the literature have shown that the launching of SATs has resulted in a significant increase in cotton–wheat and rice–wheat crop yields, resultantly increased incomes of the farmers. Application of SATs, including satellite remote sensing, drones, machine learning and image processing, monitoring, wireless sensor networks, IoT–based robotics, precision agriculture and agroforestry could be extremely useful in developing intelligent agricultural systems in underdeveloped and developing countries, with improved plant growth, high crop yield and ensuring food security. These technologies could help farmers by storing additional water, spraying pesticides with drones, practicing precision agriculture and employing sensors for assessing different environmental parameters. By making efficient use of these technologies, countries could be able to increase the yield of their crops, which, in turn, will contribute to the reduction of poverty and the elimination of food insecurity.</p>\u0000 </div>","PeriodicalId":14864,"journal":{"name":"Journal of Agronomy and Crop Science","volume":null,"pages":null},"PeriodicalIF":3.7,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142234716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
