This study aimed to evaluate, for the first time, the phenolic contents, antioxidant, antibacterial, and antifungal properties of the Hodna sub-arid lentisk seed oils obtained through hot (traditional method) and cold extraction techniques. The cold pressing process resulted in a much greater yield (15%) compared to the traditional method (5%). Both Hodna lentisk oils obtained by cold pressing (HLCO) and hot extraction (HLHO) were rich in polyphenols, but the total phenolic content of HLCO (94.54 mg GAE/100 g) was twice that of HLHO (48.02 mg GAE/100 g), making HLCO a richer source of phenolic compounds. HLHO and HLCO showed very high free radical scavenging activity, which were respectively 113.81 and 107.47 mM TE/100 g. Limited inhibitory effects were observed against a panel of five pathogenic bacteria and six fungal strains. The sub-arid origin of P. lentiscus oils, more particularly the cold-extracted one, may be a natural source of promising phenolics compounds that could be incorporated into new products or replace synthetic compounds in the health, food, and cosmetics sectors.
Considering the increasing global population and the importance of food security, it is crucial to develop sustainable agricultural production systems that reduce greenhouse gas emissions, are climate-resilient and sensitive, prevent erosion, and conserve soil. This study aims to compare strip tillage, one of the conservation tillage techniques, with conventional tillage in terms of plant emergence parameters and yield in cotton cultivation. The research was conducted between the 2023–2024 on an experimental field located in the Ceyhan Plain of the Çukurova Region. Cotton (Gossypium hirsutum L.) was used as the plant material. The results showed that the highest mean emergence date was observed in the conventional tillage method (12,61 days). In other words, plant emergence occurred in a shorter time (11,88 days) with the strip tillage method compared to conventional tillage. The emergence rate index was higher in the strip-till method (2,09 plants/day m). Regarding the percentage of emergence, the highest value was observed in the strip tillage method (%99,95), while the lowest value was recorded in the conventional tillage method (%91,50). In terms of yield, conventional tillage an average yield of 472,5 kg/da −1, while strip tillage resulted in an average yield of 461 kg/da −1. In conclusion, cotton plants grown using the strip tillage method demonstrated better performance in terms of plant emergence parameters. The strip tillage method, which is sustainable, protective, restorative, environmentally friendly, and economical, should be promoted as an alternative to conventional tillage practices.
An experiment conducted to the asses the carcass quality of Landrace X Desi pigs under split weaning and different feeding regime was carried out at Indian Veterinary Research Institute, Izatnagar, Barielly, Utter Pradesh. Eighteen pregnant gilts (62.5% Landrace and 37.5% Desi) were randomly divided into two groups (C and T, respectively) having 9 gilts each. After birth of piglets in control group were allowed to suckle their dams until 56 days of age and kept as control and weaned thereafter. In other half (T), heavier piglets (> 1.2 kg body at birth) were weaned at 28 days and remaining comparatively lighter piglets were weaned at 42 days after birth. Weaned piglets again distributed 3 subgroups with 15 piglets in each group and these piglets were fed with 100% Concentrate ration, 50 Concentrate and 50% Kitchen waste and 100% kitchen waste. The split weaned heavier half piglets (T2) and lighter half (T3) were again distributed 3 subgroups and fed with same as control groups. All the selected animals were housed on similar concrete floored pens provided with separate feeder and water facility with a run area behind. After 12 weeks, 4 males were selected and reared upto 60 ± 5 Kg from each subgroup for studying the carcass traits. Treatments had no significant effect on live weight, carcass weight, carcass length, Bach fat thickness. But significant (P<0.01) effect was observed on dressing percentage and loin eye area. Dressing percentage was highest in T2 (70.56±0.64) compared to T1(67.24±0.74). Loin eye area (sq.cm) was significantly higher in T1 (39.67±1.2). Diet had highly significant (P<0.01) effect on live weight, fasting weight, head, carcass weight, back fat thickness, belly, loin and ham but dressing percentage, carcass length and picnic had significant (P<0.05). Hence, based on the study it is advisable to feed pigs with concentrate and kitchen waste diet to get maximum economic value due to good carcass quality.
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.
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.
