Abstract Seaweed extract contains plant growth regulators and bio-stimulants that enhance plant growth and development. In Bangladesh, winter rice (Boro rice) in the nursery bed often shows poor seed emergence and weak seedling growth due to low temperature. This problem can be addressed by using seaweed extract as a seed priming agent and bio-stimulant. The objective of this study was to evaluate the effectiveness of seaweed extract (Crop Plus) on seed emergence, seedling growth, and vigor of winter rice in the nursery. Two experiments were conducted at Bangladesh Agricultural University using BRRI dhan89. The laboratory experiment… More >

Abstract Phytophthora blight is a devastating disease of pigeon pea (Cajanus cajan) that severely impacts plant growth and productivity. This study investigates the morphological, anatomical, and biochemical responses of a susceptible variety (ICPL 11260) and a resistant variety (IPAC-02) following infection by Phytophthora. Morphological analyses showed that infection caused a drastic reduction in root length, shoot length, leaf number, fresh weight, and dry weight in the susceptible ICPL 11260 variety, with reductions ranging from 0.5- to 2-fold compared to non-infected controls. Anatomical observations revealed pronounced cellular damage and mycelial invasion in infected ICPL 11260 plants by 30… More >

Abstract Mexican oregano (Lippia graveolens Kunth) is an aromatic species of high culinary and medicinal relevance. In Mexico, more than 40 taxa with characteristic aroma and flavor are commercially recognized as oregano, with L. graveolens being the most widely distributed and economically important. Despite its relevance, few domesticated or semi-domesticated cultivars exist, and wild populations remain the main source of raw material, raising concerns regarding sustainability and quality standardization. The essential oil and oleoresins of L. graveolens possess recognized bioactivity, including antioxidant, antifungal, antibacterial, and anti-inflammatory properties, largely attributed to phenolic compounds such as thymol and carvacrol. Given the… More >

Abstract To ensure the efficient use of resources, particularly in water-scarce arid and semi-arid regions where abiotic stress threatens food security, assessing soil and climate suitability for specific crops is crucial. Simultaneously, food production must align with sustainable development goals by minimizing negative environmental impacts. Therefore, establishing agro-climatic suitability using a spatiotemporal approach is essential. This involves three key steps: first, determining the climatically appropriate months based on the species’ requirements (temporal suitability), and second, establishing the soil suitability of specific plots (spatial suitability). Following this, quantifying crop evapotranspiration allows for optimized water use. This study… More >

Abstract Tomato is a major economic crop worldwide, and diseases on tomato leaves can significantly reduce both yield and quality. Traditional manual inspection is inefficient and highly subjective, making it difficult to meet the requirements of early disease identification in complex natural environments. To address this issue, this study proposes an improved YOLO11-based model, YOLO-SPDNet (Scale Sequence Fusion, Position-Channel Attention, and Dual Enhancement Network). The model integrates the SEAM (Self-Ensembling Attention Mechanism) semantic enhancement module, the MLCA (Mixed Local Channel Attention) lightweight attention mechanism, and the SPA (Scale-Position-Detail Awareness) module composed of SSFF (Scale Sequence Feature… More >

Abstract Spikelet filling characteristics in early-season rice in southern China may be distinctive due to its exposure to high temperatures during the ripening period. However, limited information is currently available on these characteristics. This study aimed to characterize spikelet filling in early-season rice and identify the key factors contributing to its improvement. Field experiments were conducted over two years (2021 and 2022) to mainly investigate the proportions of fully-filled, partially-filled, and empty spikelets, along with the biomass-fertilized spikelet ratio and harvest index, in 11 early-season rice varieties. The results revealed significant varietal variation in spikelet filling,… More >

Abstract The cultivation of Soledad pepper (Capsicum annuum L.) is essential in Oaxaca and Veracruz, but it faces issues with pests and diseases, which affect yield and cause economic losses. To mitigate these impacts, farmers have started using biostimulants such as chitosan and plant growth promoting bacteria instead of agrochemicals due to their environmental and health benefits. This study evaluated the effect of Bacillus subtilis and chitosan, both individually and combined, on the growth, yield, and fruit quality of Soledad pepper under greenhouse conditions. Four treatments were applied at different stages of the crop cycle: Q (Chitosan), BS (Bacillus More >

Abstract ERD4 proteins, members of the early responsive-to-dehydration family, act as plasma membrane ion channels that contribute to ion homeostasis and modulate plant response to abiotic stresses. However, the functions of ERD4 homologs in non-vascular species remain largely unexplored. Here, we characterized an ERD4 family homolog in Physcomitrium patens (Hedw.) Mitt., PpCSC1 (Calcium-permeable Stress-responsive Cation Channel 1), and investigated its role in salt stress response. PpCSC1 localized to the plasma membrane and functioned as a non-selective cation channel permeable to Na+, K+, Ca2+, and Mg2+. Under salt treatment, PpCSC1 transcripts were markedly downregulated, whereas overexpression lines exhibited enhanced salt sensitivity.… More >

Abstract Panax species are globally recognized for their high medicinal and economic value, yet large-scale cultivation is constrained by high production costs, progressive soil acidification, and persistent soil-borne diseases. Although various soil improvement strategies have been tested, a comprehensive synthesis of their comparative effectiveness has been lacking. Here, we conducted a meta-analysis of 1381 observations from 54 independent studies to evaluate the effects of conventional fertilizers, microbial fertilizers, organic amendments, and inorganic amendments on Panax cultivation. Our results demonstrate that microbial fertilizers, organic amendments, and inorganic amendments significantly increased soil pH, thereby ameliorating soil acidification. Among them,… More >

Abstract Epimedium is commonly used to treat bone injury and kidney disease, with prenylated flavonol glycosides (PFGs) as its active ingredients. It has attracted much attention due to prominent healthcare and therapeutic effects, but faces problems of adulteration with closely related species and confusion about geographical origins. In this study, multiple technical approaches were employed to identify its genetic characteristics and metabolic differences. Based on DNA barcoding, 20 batches of samples were analyzed. The genetic distances of matK, ITS and psbA-trnH within species were all smaller than those between species, and psbA-trnH along with ITS + psbA-trnH proved most effective… More >

Abstract In recent years, the world has faced rising global temperatures, accumulative pollution, and energy crises, stimulating scientists worldwide to strive for eco-friendly and cost-effective solutions. Biochar has materialized as a
favorable tool for environmental remediation, indicating efficacy as an efficient sorbent substance for both
inorganic and organic pollutants in environmental field. These unique properties exclude improved surface
functionality, porous morphology, large specific surface area (SSA), cation exchange capacity (CEC), robust
adsorption capabilities, environmental stability, and embedded micronutrients. Biochar exhibited potential
characteristics for environmental oversight, greenhouse gas (GHG) emission reduction, and soil fertility improvement. This review… More >
