Abstract
Transfer of technology is rapidly evolving from traditional, top-down, face-to-face methods where experts directly instruct farmers toward integrated, digitally enabled, multi-channel advisory systems. Digital technologies including mobile applications, SMS advisories, IoT sensors, AI-driven analytics, and decision-support systems (DSS) offer unprecedented opportunities to enhance outreach, deliver personalized recommendations, strengthen farmer decision-making, and improve resource-use efficiency. These tools can facilitate two-way communication, integrating local knowledge and feedback into extension services, while also supporting market linkages, climate risk management, and sustainability goals. Evidence indicates that mobile and SMS-based advisories are highly inclusive and scalable, whereas IoT, AI, and DSS represent advanced precision technologies with adoption challenges due to costs, digital literacy, connectivity, and institutional capacity. While digital extension can increase productivity, incomes, and resilience, it also risks reinforcing existing inequalities and creating dependencies if accessibility, local relevance, trust, and human facilitation are insufficiently addressed. Key barriers include digital literacy gaps, content localization, gender and socio-economic inequities, data governance, and institutional limitations. Successful digital agriculture requires blended extension models, participatory content design, capacity-building, inclusive service and financing mechanisms, and robust policy frameworks. This review synthesizes recent empirical and market evidence on digital agriculture adoption, impacts on knowledge, productivity, and market access, and identifies research gaps and best practices for inclusive, sustainable, and scalable digital extension services.

Abstract
The population dynamics of indigo psyllid, Euphaleropsis isitis (Cotes) (Hemiptera: Psyllidae) infesting Indigofera tinctoria L. were studied under field conditions at the College of Agriculture, Vellanikkara, Kerala, from September 2024 to August 2025. Fortnightly observations on egg, nymph, and adult were recorded from 15 plants, and the population was correlated with major weather parameters viz., maximum temperature, minimum temperature, morning relative humidity, evening relative humidity, wind speed, bright sunshine hours, rainfall. The egg stage exhibited multiple peaks without any significant correlation with the weather factors. Nymphal population showed distinct peaks during February, May, and August, with a significant positive correlation with rainfall, indicating that humid conditions favoured their development. The adult population showed three major peaks (March, May, and August) and was negatively correlated with maximum temperature and bright sunshine hours, but positively correlated with evening relative humidity and rainfall. Adult and nymphal abundance was highest during the post-monsoon months (July–August), coinciding with vigorous vegetative growth of the host plants. Population reduction was recorded from mid-October to mid-December. The study suggests that rainfall, moderate temperature, and higher humidity promoted population build-up of Euphaleropsis isitis in Kerala.

Abstract
Postharvest diseases cause substantial losses in fruit production worldwide, with fungal pathogens being the primary causal agent. Traditional control methods rely heavily on chemical fungicides, which pose environmental and health concerns while promoting pathogen resistance. Induced resistance offers a sustainable alternative by activating the fruit's natural defense mechanisms rather than directly targeting pathogens. This review examines two main types of induced resistance: Systemic Acquired Resistance (SAR), triggered by chemical treatments and providing long-lasting protection, and Induced Systemic Resistance (ISR), activated by beneficial microorganisms with faster response times. Various elicitors can trigger these defenses, including physical treatments (UV-C light, heat, modified pressure), chemical compounds (salicylic acid, jasmonic acid, brassinosteroids), and biological agents (chitosan, harpin, oligandrin, beneficial microbes like Bacillus, Pseudomonas, Trichoderma, and antagonistic yeasts). Each elicitor category offers unique advantages for disease management. Application methods such as dipping, spraying, and coating enable practical implementation in commercial systems. While challenges exist regarding timing, formulation stability, and variability across fruit types, combining different elicitors and integrating them with other control strategies shows promise. As regulations tighten and consumer demand for safer produce grows, induced resistance is emerging as a key component of sustainable postharvest disease management.

Abstract
Seed germination and early seedling development are critical stages that determine crop establishment and final yield. In Sesamum indicum L. (sesame), improving germination rate and early morphological growth can significantly enhance stand establishment under variable field conditions. Two promising and complementary approaches silicon (Si) application (including seed priming) and inoculation with arbuscular mycorrhizal fungi (AMF) have been investigated across crops and in sesame specifically. This review synthesizes the available literature on mechanisms by which Si and AMF influence seed germination and early seedling traits in sesame, summarizes experimental findings (including a composite data able compiled from multiple studies), and discusses practical implications and research gaps. We show that both Si seed treatments and AMF inoculation generally increase germination percentage, root and shoot elongation, biomass accumulation, and stress resilience; combined Si + AMF treatments often yield additive or synergistic benefits. Representative experimental/compiled data are provided to illustrate typical effect sizes and to guide future experimental design.

Abstract
The objective of the works is to identify, select, cultivate and adopting strategies to yield higher Chlorella vulgaris microalgae for bio hydrogen production by performing various steps. The identification step contains sample collection, morphology and bioenergy producing capability of microalga. Selection criteria of microalgae involve several parameters i.e. easily availability, survival conditions like environmental and biological factors, efficient photosynthetic capability, rapid growth rate and biomass accumulation, high starch and lipid accumulation, sustainable cultivation and scale-up feasibility in semi-arid Malwa region, Indore MP. The process of cultivation was conducted in a photo bioreactor (PBR) or closed system. Key features of photo bioreactor (PBR) are controlled environment, scalability, high biomass productivity ease of harvesting etc. Key environmental factors, including light intensity and nutrient media, are essential in photo bioreactors (PBRs) to enhance cell biomass growth rate and yield. Chlorella vulgaris achieved a peak biomass of 4.43–4.57 g/L after 96 hours, with a maximum CO₂ fixation rate of 4.23 g/L/d and dissolved oxygen (DO) release of 1.85 g/L/d. showing highly reproducible results across optical density, transmittance, and dry weight methods. These findings highlight its strong potential for CO₂ biofixation, oxygen enrichment, and sustainable bioenergy applications.

Abstract
Ornamental flowering trees are vital in landscape gardening due to their aesthetic and ecological significance. However, commercial propagation of ornamentals often results in genetic variability and delayed flowering when propagated through seeds. Vegetative propagation helps overcome these limitations by producing genetically uniform and early-flowering plants. The present study was conducted to evaluate the effect of cutting type and auxin concentrations on clonal propagation of Pride of India (Lagerstroemia speciosa) using IBA and NAA. The experiment was laid out in Factorial Completely Randomized Design (FCRD) with three replications and seven treatments under a mist chamber. Semi-hardwood and terminal cuttings treated with IBA (1500 ppm and 1000 ppm) performed significantly better than untreated controls. Semi-hardwood cuttings treated with 1500 ppm IBA recorded the highest shoot length (25.00 cm), number of leaves (54.00), number of roots (27.00), root length (35.70 cm) and survival percentage (92.10%). The results demonstrate that clonal propagation through semi-hardwood cuttings treated with IBA at 1500 ppm is the most efficient method for commercial multiplication of Pride of India.

Abstract
Melia dubia is a fast-growing, short-rotation tree species widely cultivated for plywood, pulp, and biomass production; however, large-scale planting is constrained by poor seed germination and genetic variability. Although epicormic shoot-based propagation offers a reliable clonal alternative, the influence of branch size on epicormic shoot induction and rooting under hormone-free conditions has not been adequately quantified. The present study evaluated the effect of branch diameter and length on epicormic shoot production and propagation success. Branches were categorized into four treatments based on two diameter classes (1.0-1.5 cm and 3.0-5.0 cm) and two length classes (30 and 90 cm) and maintained under mist chamber conditions. Epicormic shoot emergence, growth attributes, and shoot vigour index were recorded after 50 days, followed by rooting of shoots in sand medium. Thinner branches exhibited earlier sprouting and higher shooting percentage but produced weak shoots that failed to root. In contrast, larger branches produced delayed sprouting but generated more vigourous shoots with higher shoot vigour index, superior rooting percentage (83.33%), complete survival, and enhanced root and shoot growth. Therefore, larger branches are the most suitable source material for efficient epicormic shoot-based clonal propagation of Melia dubia.

Abstract
The main finding of this study is a clear shift in extension priorities, moving from general awareness programs to more structured, skill-based training that meets changing climate needs. Understanding how these priorities change is important for better planning and policy decisions. While Krishi Vigyan Kendras (KVKs) regularly record extension activities, their data is rarely analyzed for deeper insights. This study looked at four years (2021–2024) of extension program data from ICAR-KVK Baramulla to track changes in priorities. We collected and analyzed secondary data on the number, type, and participation in extension programs using descriptive trend analysis. The results show a steady move from general awareness programs to more structured training, with a greater focus on skill-building and climate-responsive activities. These findings show that regular institutional data can reveal important changes in extension priorities and help with adaptive planning.

Abstract
This study examines the significant cultural and spiritual significance of nature worship within the Tipra (Tripuri) community of Tripura India, focusing on the central role of bamboo in religious rituals. For generations, the Tipra people have maintained a polytheistic, animistic belief system where natural elements including hills, rivers, and trees are revered as divine manifestations. Central to this spiritual framework is the Wathop (or Lampra Wathop), a sacred symbolic altar crafted specifically from the wathwi variety of bamboo. The Wathop serves as a vital intermediary between the community and the divine, utilized in rituals spanning the human lifecycle from birth and weddings (Kailai Panda) to purification rites following death. Beyond individual milestones, the ritual is essential for communal welfare, performed twice annually and during festivals like Ker Puja to repel negative energy and ensure agricultural prosperity. The execution of these sacred ceremonies is the exclusive responsibility of the Ochai (priest), who acts as a spiritual guide and healer, assisted by the Baruwa in assembling the ritual items. By examining these practices, this work shows the enduring legacy of bamboo-based worship as a cornerstone of Tipra identity and its role in maintaining a harmonious relationship with the natural world.
