Morphometric Taxonomy of Meloidogyne spp. Infesting Vegetable Crops in Sri Lanka via Female Perineal Pattern Analysis

Meloidogyne spp. are among the most significant plant-parasitic nematodes in agriculture, necessitating precise identification for effective management. This study aimed to identify and taxonomically characterize Meloidogyne spp. infesting vegetable crops in Sri Lanka using female perineal pattern analysis. A total of 54 root and soil samples were collected from 17 agricultural regions and analyzed at the Horticultural Crop Research and Development Institute (HORDI), Sri Lanka. Single egg-mass cultures were established using a nematode-susceptible tomato variety (KWR), and second-stage juveniles (J2) were used for precise inoculation. Perineal patterns of mature females were prepared following standard protocols and examined microscopically. A total of 101 female nematodes were identified, revealing the presence of M. arenaria (33%), M. javanica (30%), M. incognita (25%), and M. hapla (13%). M. arenaria exhibited forked lateral fields and a low dorsal arch, while M. javanica displayed distinct double lateral incisures. M. incognita was characterized by an angularly oval pattern with a high dorsal arch, and M. hapla showed a concentrated punctation between the anus and tail terminus. Host range analysis indicated that M. hapla had a narrow host range, whereas the other species were oligophagous, with M. incognita affecting a broad spectrum of crops, including tomato, spinach, brinjal, and okra. The study confirmed that M. incognita, M. javanica, and M. arenaria are the predominant Meloidogyne spp. in Sri Lanka’s vegetable-growing regions, with M. arenaria being the most frequently detected. These findings align with previous research and highlight the necessity of targeted management strategies. The results provide a valuable foundation for developing species-specific nematode control measures in Sri Lanka’s agricultural systems.

Neneng Qori Farida, Setyono Yudo Tyasmoro, Adi Setiawan

Sweet corn (Zea mays saccharata Sturt L.) is one of the horticultural commodities that has increasing market demand but declining production levels. This is because most of the fertilization that is done is continuous and excessive chemical fertilization. The use of chemical fertilizers can have a negative impact on the soil, one of which can cause damage to soil structure and function, so that it will slowly reduce soil quality. This study aims to assess the effectiveness of using chicken manure in optimizing KNO₃ fertilizer so as to increase the growth and yield of sweet corn plants (Zea mays saccharata Sturt L.). The research was conducted in Jemekan Village, Ringinrejo Subdistrict, Kediri District, using a Spli Plots Design using doses of chicken manure (0, 4, 8, and 12 tons.ha-1) and KNO₃ fertilizer (0, 25, 50, and 75 kg.ha-1). The results showed that the combination of chicken manure dose of 12 ton.ha-1 with KNO₃ 25 kg.ha-1 produced higher cob fresh weight than other treatments. Chicken manure contributed to the improvement of soil structure and increased nutrient availability, while KNO₃ supported vegetative growth and yield. The interaction between the two fertilizers showed an increase in macronutrient uptake (N, P, K) by plants, with nitrogen and potassium uptake increasing significantly in the late vegetative to early generative phase. This study concludes that the use of chicken manure and KNO₃ is an effective and environmentally friendly solution to increase sweet corn productivity.

A Facet of Marketing Effectiveness of Button Mushroom Production in Mid-Hills of Himachal Pradesh

Girish Mahajan, Rajesh Thakur

Mushroom marketing involves promoting and selling mushroom produce to wholesalers, retailers and consumers. Studying the marketing aspect of button mushroom production is crucial because it helps mushroom growers to understand consumer demand, optimizing pricing strategies, identifying effective distribution channels and ultimately maximizing profits by ensuring their mushrooms reach the market efficiently and meet consumer expectations, especially considering the perishable nature of the product and need to maintain supply fluctuations in a dynamic market. In this respect, an attempt has been made in this paper to identifying the major marketing channels involved in mushroom business and the different functionaries involved in transferring the product from producer to ultimate consumers along with their marketing costs, margin, price spread, marketing efficiency and the producer share in the consumer’s rupee. It has been found that three marketing channels were followed in the study area but channel-2 (Mushroom growers—Retailer---consumer) was the most widely used channel in which 48.16 per cent of the produce was marketed by 40.60 per cent of the mushroom growers. The producer’s share in the consumer’s rupee was highest for chaneel-1 (98.87 %) but this channel could absorb only 10.55 per cent of the total produce. Channel-2 was the important channel from the sale point of mushroom as it absorbs 48.16 per cent of the produce and was used by 54 mushroom growers and had 73.65 per cent of the producer’s share in the consumer’s rupee. Additionally, opinion of the mushroom growers and their marketing functionaries were also enlisted regarding their problems and the constraints which hampered them not to take this enterprise/venture as their farming business in a big way. In this context, production, marketing, institutional and social problems are the major constraints which inhibit them not to adopt this venture as their business in a big way.

Mukesh, Sehar Anwar, Amna Gulshan, Maria Ali, Khawaja Muhammad Ali, Yahui Guo

This study examines the production of antimicrobial paper of sugarcane bagasse at the pilot-scales and also evaluates its potential to displace conventional plastic packaging. Early chemical analysis indicated the high cellulose content of SCB (≈45%) was suitable for pulping and paper formation. Pilot-scale experiments showed pulping yields in the 55–70% range under optimized conditions (120–160 °C, 30–90 min), and attributed improved fiber separation and less residual lignin to the established process. To improve their antimicrobial activity and mechanical properties, nanocomposite coatings based on silver nanoparticles (AgNPs,) chitosan-silver (CS-AgNPs), and silver/zinc oxide (Ag/ZnO) were deposited. The bending stiffness (up to 23±3 N/mm), tensile strength (up to 41±3 Nm/g), and folding endurance (up to 47±5 cycles) are vastly superior compared with the data of uncoated samples. Abstract: Antimicrobial testing against E. coli and S. aureus showed significant inhibition zones (maximum 17.0 mm), Ag/ZnO 2% exhibited the best antimicrobial activity. A preliminary cost and energy analysis revealed that significant drivers of cost came from nanoparticle synthesis and drying stages, and energy analysis reported a cumulative energy requirement of 1.3 kWh/kg of paper. Notwithstanding these obstacles, the results underscore the promise of SCB in obtaining high-performance, antimicrobial packaging. To enable large-scale production of this sustainable material, improvements in coating deposition, cost management of nanoparticles, and energy efficiency may facilitate commercial roll out.

Nguyen Thi Lang, Bui Chi Hieu, Bien Anh Khoa, Nguyen Trong Phuoc, Bui Chi Buu

This study to quantify flavonoids and polyphenols between 10 different rice varieties from white and brown rice. The phenolic content (TPC) of 10 rice varieties in the Mekong Delta :TPC of brown rice and white rice of different rice varieties differed significantly (p < 0.05). The TPC measured in brown rice was significantly higher (118.98-206.06%) than in white rice. Brown rice TPC levels were highest in NepThan (771.12 mg/100 g), while the lowest levels were found in OM5451 (100.12GAE mg/100 g). The highest and lowest levels of GAE were found in HATRI 11 (215.06 mg/100 g) and OM5451 (133.08 mg/100 g). The difference in the total phenolic content between varieties can be attributed to differences in genotype. It is noteworthy that HATRI 11's TPC is the highest among white rice, but it is only 119.47% higher than the lowest white rice varieties. The flavonoid content (TFC) of 10 TFC rice varieties of brown rice and white rice of different rice varieties differed significantly. The TFC of brown rice is in the range of 142.26–919.1RE mg/100 g, while white rice is in the range of 68.72–645.29RE mg/100 g: brown rice has a total flavonoid content 10%-20% higher than white rice. The total anthocyanin content in free form and the bonds vary between different genotypes of pigmented rice bran. The content of free and binding anthocyanins in the rice fraction of ten different genotypes of pigmented rice ranged from 2.18 to 256.11 and 5.25 to 38.51 mg of Cy3-GE/100 g DM, respectively. The highest concentration of anthocyanins was detected in free form. Nep Than showed the highest anthocyanin content (234.62 mg Cy3-GE/100 g DM), followed by HATRI 11 (73.88 mg Cy3-GE/100 g DM) and white rice (50.42 mg Cy3-GE/100 g DM). Polyphenols and flavonoids and the mechanism of rice growth and development from the limited description of previous works. Our studies have enriched the active compounds of rice and laid a solid foundation to improve the active compounds for the type of rice served as functional foods for Vietnam.

Effects of Leaf Reserved and clipped on Axillary Bud Quality in Umbrella-Shaped Hevea brasiliensis ‘Reken 628’ Bud-sticks

Zhennan Cha, Jinglan Ruan, Xiying Jiang, Xuedan Gong, Xianhong Chen, Jun Wang

The insufficient supply of bud-sticks from traditional single-stem rubber trees (Hevea brasiliensis) remains a bottleneck for mini-seedling budding in commercial rubber plantations. To address this issue, we investigated the impact of leaf reserved versus leaf clipped on axillary bud development in umbrella-shaped ‘Reken 628’ rubber trees. After removing apical dominance by topping, the plants developed multiple branches, yielding 4–6 times more bud-sticks than conventional methods. Bud-sticks were harvested when petioles detached naturally and leaf scars turned brown. Axillary buds (scale buds and petiole buds) from the second (2nd) and third (3rd) leaf whorls were analyzed for quantity, moisture content, and morphological traits (bud scar dimensions, bud eye size). :Leaf reserved 2nd buds exhibited superior quality, with significantly higher moisture content (9.40–10.69%), larger bud scar width (43.21%), and thicker bud scars (19.69%) compared to their clipped counterparts (P < 0.05). Leaf-clipped reduced physiological consistency, increasing variability in leaf length (CV: 21.40–25.86%), leaf width (20.79–23.36%), and stem moisture (5.89%). Correlation analysis revealed strong synergies between leaves reserved, stem thickness, and bud moisture, critical for grafting success. We conclude that reserved leaves on 2nd whorls of umbrella-shaped trees optimizes bud-sticks quality for mini-seedling budding. Post-topping management should prioritize frequent irrigation and balanced fertilization to sustain nutrient supply. This strategy enhances bud-sticks yield, grafting efficiency, and survival rates, offering a scalable solution for high-demand rubber nurseries.

Genome-Wide Identification and Characterization of Superoxide Dismutase (SOD) Gene family in Finger Millet (Eleusine coracana)

The metallo-enzyme superoxide dismutases (SODs) are significant in protecting plants from environmental challenges as well as regulating their growth and development. Although many plants have been determined to possess SOD gene families in their genomes, it is known, very scarcely, about such gene families in finger millet (Eleusine coracana). This study explored the SOD gene family across the entire genome of finger millet. A total of 10 SOD genes were discovered, comprising eight Cu/ZnSODs and two Fe/MnSOD. These EcSODs are spread irregularly throughout 3A and 8B chromosomes. Phylogenetic analysis revealed that SOD proteins in plants possibly classified into three primary groups for both EcCu/ZnSODs and EcFe-MnSODs. The motif and exon/intron makeup of SOD genes are conserved within the same subgroup. Protein structure prediction showed all homologs contains highest similarity with SOD peptide structure. Furthermore, numerous cis-elements that react to distinct stresses were distributed differently. The various biological processes associated with background molecular roles of SODs are further demonstrated by gene ontology analysis. The transcriptional factors discovered indicate that SODs are mostly connected to external environmental and biotic stress. This study lays the groundwork for future cloning, Genetic manipulation of SOD gene in finger millet which contributes towards finger millet breeding programs.

Aditi Sarma, Ningombam Priyadarshi, Rachana Chakraborty, Padmashree Kulkarni

Discharge of melanoidin containing distillery wastewater raises a serious environmental concern as it can pose severe health risks to aquatic bodies and soil due to absorption of sunlight, change in the alkalinity and inhibition of seed germination. Several physicochemical and biological based clean-up technologies have been investigated to combat this environmental pollution. Strategies to decolorize the distillery effluents using potential microbial communities are efficient and cost-effective. Distillery effluent treatment methods using fungi, algae and bacteria have demonstrated promising results. Microbial enzymes involved in the mechanism of decolorization have also been studied extensively. Current advances in melanoidin decolorization using nanoparticles show great promise for treating industrial effluents. The focus of the present review is to explore the current approaches of use of different groups of microbes and novel approaches such as use of nanoparticles in decolorization of melanoidin containing distillery wastewater.

Contribution of green technologies on infrastructure performance in Rwanda, a case of green buildings constructed in the green Gicumbi project

In Rwanda, integrating green technologies in building projects presents an opportunity to enhance infrastructure performance while minimizing environmental impact. However, the extent to which these technologies contribute to the overall effectiveness of these infrastructures remains underexplored, especially in rural contexts like the Gicumbi District. Therefore, this study aimed to assess the contribution of green technologies used in green building projects to infrastructure performance. To achieve this objective, the study used a descriptive research design and a census sampling technique to select the entire population of 107 people, including the residents and beneficiaries of the green buildings project. Primary data were collected through a combination of questionnaires, interviews, and direct observations, while secondary data were gathered through documentary analysis and published research studies. The findings revealed that all green technologies such as resources-efficient design, low-emission materials, and waste management have a significant positive influence on the performance of the Green Buildings project in the Gicumbi district where a increase of one unit in resources-efficient design, low-emission materials, and waste management would lead to increase of 0.152, 0.14, and 0.178 in performance of Green Buildings. The study concluded that the change of 65% in the performance of Green Buildings is due to green technologies in terms of resource-efficient design, low-emission materials, and waste management at a 95% confidence interval.

Teleconnection between Atmospheric Circulation and Meteorological Drought in Southwest China

Meteorological drought represents one of the most prevalent and consequential climate disasters in China, exerting severe impacts on regional ecosystems and socioeconomic development. This study investigates the teleconnection between meteorological drought and atmospheric circulation patterns in Southwest China from 1960 to 2022. Employing the Standardized Precipitation Evapotranspiration Index (SPEI) across multiple temporal scales alongside atmospheric circulation data, we conducted a comprehensive analysis using statistical methodologies including run theory, Mann-Kendall trend tests, and Pearson correlation analysis. These approaches enabled an in-depth examination of the spatiotemporal characteristics of drought events and their atmospheric teleconnections in the region. The results demonstrate that (1) Since 1960, the seasonal drought occurrence probability in Southwest China follows the order: spring > winter > autumn > summer. Light and moderate droughts are the predominant types in the study area, while severe droughts occur relatively infrequently, with no extreme drought events recorded. (2) Significant spatial variations in meteorological drought exist at seasonal scales across Southwest China. Spring drought generally shows a mitigation trend, summer exhibits a northeast-wet/southwest-dry pattern, autumn demonstrates increasing aridity in most regions, and winter displays a distinct southeast-wet/ central-dry/ northwest-wet gradient. (3) Regional atmospheric circulation influences exhibit distinct patterns: ENSO demonstrates the most pronounced teleconnection impact across the entire region; PDO shows strong secondary influence, particularly in southeastern and northern areas; AO exhibits relatively weak effects, mainly affecting northern and northwestern sectors; and NAO displays minimal impact, with only 7.1% of southern and northern areas showing significant positive correlations. These findings provide valuable scientific references for drought research and integrated management in Southwest China, offering both theoretical foundations and empirical support for regional economic development planning. The results contribute to enhanced drought monitoring systems and informed policymaking for climate adaptation strategies in the region.

Soil Pollution and its effects on Agriculture

Dr. Anupriya Gupta, Dr. Kiran Maheshwari, Netram meena

Soil pollution can lead to the emergence of new pests and diseases by changing the balance of ecosystems and causing the disappearance of predators or competing species that regulate their biomass. It also contributes to the spreading of antimicrobial resistant bacteria and genes, limiting humanity’s ability to cope with pathogens. Pollution can also cause the quality of soil to dwindle over time, making it harder to grow crops. Currently, the degradation of land and soils is affecting 40 per cent of the world’s population. Soil has a key role to play through its ecosystem functions as it affects water regulation, nutrient recycling, food production, climate change and the biodiversity of terrestrial ecosystems. Transitioning from soil degradation to practices that restore soil is critical to ensure the food security and wellbeing of generations to come has now become a call of time.

Jay N. Yadav1, Hemant Kumar Singh2, Vibha Yadav1, R.P. Diwakar1

Artificial insemination and embryo transfer have emerged as revolutionary technologies in the livestock industry, offering remarkable opportunities for genetic improvement and efficient herd management. In modern agriculture, these assisted reproductive technologies are increasingly being utilized for a wide range of applications, including out-of-season estrus induction, enhancement of reproductive performance, and preservation of endangered species or breeds. Nonetheless, significant advancements have been made in embryo technologies, particularly in the areas of estrus synchronization, superovulation, and in vitro embryo production. Incorporating applied reproductive technologies continues to effect animal production systems by providing producers opportunities to enhance genetics, reduce transfer of disease, advance fertility, and ultimately increase offspring value. Improvements in fertility and technology, reductions in cost, and improvements in ease of application will ensure that more cattle producers will adopt applied reproductive technologies in future years. However, incorporation of applied reproductive technologies into production systems will vary worldwide depending on cattle markets, infrastructure, production systems, and climate.

Collection and Quantification of Infectious Medical Waste at the University Hospital Center (CHU) of Abidjan / Cocody, Health and Environmental Risks, Ivory Coast

Coulibaly Foundere, Sinan Adaman, Yao Innocent Kobenan

A questionnaire, an interview guide and observation were used to collect data for this action research. The CHU of Cocody has a modern technical platform and a wide range of treatment options for various diseases. Thus, the vastness and diversity of the CHU's care activities inevitably lead to the production of enormous medical waste of various types. Among these wastes, infectious medical waste and sharp objects (OPCT) are the subject of this research. In fact, the CHU produced 4267.12 kg of these infectious medical waste and sharp objects (OPCT) from 01/01/2024 to 31/03/2024. Quantification by weighing of this infectious waste, made it possible to note that 40.04% of this waste, or 1708.66 kg are OPCT and 59.96% or 2558.46 kg, are infectious medical waste. 90% of this waste is collected, however the route of the remaining 10% is unknown according to our surveys. 66.66% of the administrative and technical staff of the CHU. 72.72% of the PCI and PGOP staff are aware of the existence of the ministerial decree on the regulation of the management of health waste. The waste management process requires the establishment of a program for the management of said waste. This program, although existing at the PCI, requires training of the various actors in the medical waste management process as a whole. Sorting is abnormally done because pre-collection is and collection can only undergo. Only 90% of infectious medical waste is collected. The three-quarter (¾) filling of safety boxes (BS) and the method of introducing OPCTs into the BS are not respected by a large part of the medical staff. In fact, 45.46% of this staff is not even aware of the existence of decree 131 of June 3, 2009 relating to the management of medical waste and the lack of training is the cause.

Dipak Khanal, Dhurba Banjade, Laxmi Prasad Joshi, Aman Shrestha, Sanisha Khatri

A study assessed the farmers' knowledge of technology adoption status in large cardamoms in the Taplejung district of Nepal. For the study, primary data were collected from 60 randomly selected farmers using a semi-structured interview schedule, focal group discussion (FGD), and key informant interview (KII). Secondary information was collected by reviewing different relevant publications. The data were processed and analyzed using descriptive statistics through SPSS and Excel programs. The study shows that farmers are aware of modern technology available for large cardamom cultivation. Most farmers adopt modern irrigation techniques (86%) to irrigate cardamom orchards. Only 2% farmers used chemical fertilizer in cardamom orchards, and 50% of farmers use organic manure. Mainly, cultural practices are used to control diseases, insects and pests. During field preparation, 72% of farmers used traditional tools, i.e., spades. For pruning operations, only a few farmers, 28%, used chainsaws but mainly used secateurs, and for weeding, hand tools are used primarily than brush cutters (only 33% adopted). The study shows that most farmers adopt improved air dryers (68%) rather than traditional dryers for post-harvest technology. The tail trimming method is carried out by 86% of cardamom farmers, and grading operation is not carried out before selling. Farmers mostly received subsidies from PMAMP and a few from the Agriculture Knowledge Center and other organizations. Furthermore, a lack of financial resources, technical issues, a lack of training or capacity-building programs, and difficulties with maintenance and repair were the significant constraints to adopting technology.

Keshram Meena, Lokesh Gupta, Bhavya Pal, Pradeep Nodal, Manoj Jat

The current study was planned to examine the “Impact of adding powdered Azolla (Azolla pinnata) leaves to the diet on the carcass and economic characteristics of turkey poults”. One hundred and twenty-eight-day-old turkey poults were randomly assigned to four treatment groups, each consisting of eight poults and four replicates. Azolla meal was added to the basal diet at 2.5% (T2), 5% (T3), and 7.5% (T4) levels to create three experimental diets. The control group (T1) was fed a basal diet without azolla supplementation. The dietary treatments were arranged in complete randomized design and analysed for the carcass traits and economics of rearing turkey poults. The findings ascribed to improved live weight, eviscerated weight, dressed weight and B: C ratio. The results indicate that up to 5% of Azolla leaf powder can be added to turkey feed as an unusual feed item without causing any negative side effects.

Mohith K, C Narayanaswamy

The research was undertaken in the Tumkur district of Karnataka during 2022–2023 adopting an ex-post-facto research design to compare the technological gap among coconut growers. Tumkur was deliberately chosen for its status as one of the state’s leading coconut-producing regions. Based on differences in productivity, four taluks namely Tiptur, Turuvekere, Chikkanayakanahalli and Sira were selected from the district’s ten taluks. A total of 120 coconut farmers with 30 respondents randomly chosen from each taluk formed the study sample. The comparison of the technological gap among coconut growers using the Kruskal-Wallis one-way ANOVA showed that there is a significant difference in the technological gap among taluks with H-value of 44.43 significant at one per cent level. Where Tiptur taluk performed better with 32.93 mean rank followed by the Turuvekere taluk with mean rank 47.92 and then followed by the Chikkanayakanahalli taluk with mean rank 74.93 then by the Sira taluk with mean rank 86.22 where it indicates that as the mean rank value is less/decreased the technological gap is also less/decreased and vice versa.
