Mapping the Global Research Trends of Renewable Energy -Biogas from Animal Dung: A Bibliometric Critical Research Analysis
Biogas provides renewable, eco-friendly energy alternative to fossil fuels, supports sustainable waste management and addresses the global energy challenges. The bibliometric analysis explores the global research trends in biogas/biofuel from 2000 to 2024, indexed in the Scopus database. The documents obtained were 744 from 334 sources, with an annual growth rate of 16.91 per cent. India, Indonesia, and Nigeria are leading countries in research output, reflecting significant contributions in this research area. The analysis also reveals robust regional and international collaboration networks, particularly in Southeast Asia, Africa, and South Asia, facilitating knowledge sharing and innovation. The most frequent words/terms like biogas (267 occurrences) and anaerobic digestion (171 occurrences), co-digestion (73), reflecting the biogas production processes. Terms like "biofuel", "waste management" and “emission” have seen a surge in the recent years, indicating an increased focus on the broader implications of biogas and waste-to-energy systems. This study has provided valuable insights for researchers, policymakers, and industry stakeholders aiming to develop sustainable waste management and energy production strategies.
From Field to Fact: Analyzing the Communication and Information Ecosystem of Rapeseed-Mustard Farmers
The communication behavior of farmers significantly influences their adoption of agricultural innovations and sustainable practices. This study explores the communication channels and behavioral dynamics of rapeseed-mustard growers in Dhemaji district, Assam, where productivity disparities persist despite the crop's economic significance. A purposive sampling method selected 120 respondents across three blocks, utilizing a pretested interview schedule for data collection. Findings reveal that informal and local community sources, such as progressive farmers (60% regular use) and input dealers (54.17% regular use), are the most preferred channels due to their accessibility, trustworthiness, and practical advice. Government and institutional sources, including extension officers (40% regular use), are valued for their credibility but face challenges like limited reach and awareness. Extension programs such as Kisan Melas (38.34% regular use) and field demonstrations (37.5% regular use) attract moderate participation, emphasizing their role in hands-on learning. Mass media sources like television (41.68% regular use) and social media platforms (46.68% regular use) provide accessible and timely information but are hindered by digital literacy barriers, particularly for emerging channels like mobile apps (21.67% regular use) and the internet (26.67% regular use). The study underscores the need to enhance farmer-extension linkages, improve awareness of digital tools, and customize mass media content to ensure relevance. These insights can inform farmer-centric agricultural policies and communication strategies.
Arecanut based cropping system –A way forward towards improvement of soil quality and profitability of the farming community
Soil quality play a key role in ecosystem functions for sustained crop productivity and promotion of plant health. In recent years, pronounced decline in soil health has been observed globally, resulting from non-adoption of appropriate agricultural practices and land-use approaches. Long-term sustainability of perennial crops like arecanut is threatened by soil degradation resulting from intensive land use practices in small and marginal holdings. Effective utilization of natural resources is encouraged by temporal and spatial arrangement of crops of different height, canopy patterns and root architecture in arecanut based cropping system (ABCS) become effective in improving productivity and also bringing gradual improvement in the soil properties by continuous addition of biomass into soil. Cropping system approach also helps to meet the diversified need of the farmers, increased profitability per unit area and mitigating the risk of mono-cropping. In this context, crop diversification in arecanut plantation with compatible subsidiary crops under six models were evaluated and results indicated significant improved of soil organic carbon (0.60% to 0.86 %), soil reaction (5.43-5.68) status over mono-cropping in the top layer of soil, along with a positive impact on the availability of essential macronutrients. ABCS involving crop combination of arecanut with black pepper, bay leaf, pineapple and colocasia contributed to higher chali equivalent yield (3,761 kg ha-1) from the subsidiary crops. ABCS not only providing additional income from different component crops, but also increased the chali yield even up to 50 % more than arecanut mono-cropping with highest net return per rupee of investment (4.21).
Marine-derived antioxidant fortification of chicken nuggets using Sargassum tenerrimum seaweed
The study envisages assessment of antioxidant activities and fat deteriorative parameters in Sargassum tenerrimum incorporated functional chicken nuggets. Significant reduction of cholesterol content by 32.60% proves its potential to develop low fat meat products. The enhanced antioxidant activities such a DPPH radical scavenging activity, ABST decolourization assay and Ferric acid reducing ability, and the lipid deteriorative parameters such as TBARS, FFA and PV of S. tenerrimum incorporated millet based (7% kodo millet + 3% refined wheat flour) chicken nuggets proves the synergistic impact of S. tenerrimum seaweed in kodo millet based chicken nuggets over the refined wheat flour incorporated nuggets. The results reveal that the S. tenerrimum is a candidate source of functional ingredient in chicken meat nuggets.
Production performance and egg quality characteristics of commercial layer chicken on dietary supplementation of Panchagavya and Phytogenic feed additive
The objective of this study was to evaluate the effect of dietary supplementation of panchagavya (PG) and phytogenic feed additive (turmeric) in commercial layers on production performance and egg quality characteristics. Four-hundred-day-old commercial layer chicks (BV-300) were randomly allotted into eight treatment groups with five replicates of ten chicks per replicate and reared upto 30 weeks of age. Dietary treatment groups consisted of T1 (control)-basal diet and T2 group were fed basal diet with oxytetracycline-50 ppm. The groups T3, T4 and T5 were fed basal diet supplemented with 5, 7.5 and 10 g/kg of panchagavya respectively. The other treatment groups T6, T7 and T8 were fed basal diet supplemented with turmeric 1 g/kg in combination with panchagavya at 5, 7.5 and 10 g/kg levels respectively. The egg production performance was recorded for the period from 19 to 30 weeks of age. Age at sexual maturity, age at 50 and 90 per cent egg production and feed consumption were recorded. The feed efficiency per dozen eggs, feed efficiency per kg egg mass, hen day and hen housed egg production were calculated. The egg quality characteristics such as egg weight, specific gravity, albumen index, haugh unit, yolk index, yolk colour and eggshell thickness were recorded. The results obtained from this study shown that the age at sexual maturity was significantly (P<0.05) earlier in all treatment groups except T7 (PG-7.5 g/kg and turmeric -1g/kg) group which attained sexual maturity in later age (129.40 days). No significant difference observed between the treatment groups for age at 50 and 90 per cent egg production. The results on hen day and hen housed egg production (per cent), feed consumption (g/bird/day) from 19 to 30 weeks of age showed no significant difference between the treatment groups. The overall feed efficiency per kg egg mass (19-30 weeks) showed significant (P<0.05) difference. Moreover, better feed efficiency per kg egg mass (2.35 and 2.37) was observed in T2 (antibiotic) group followed by T6 group (PG – 5 g/kg and turmeric -1 g/kg) as compared to other treatment groups. The results showed no significant effect on the egg quality characteristics such as shape index, albumen index, Haugh unit and yolk index of commercial layer chicken eggs between the treatment groups. Yolk colour (5.20) was significantly (P<0.01) higher in T6 (PG -5 g/kg and turmeric -1 g/kg) and T7 (PG -7.5 g/kg and turmeric -1 g/kg) groups as comparison with antibiotic fed group (4.50).
