ABSTRACT: In Jashpur district, there is renewed concern about post-harvest losses which account for 20–30% loss of farm produce. The lack of adequate storage facilities also affects produce quality, reducing produce market value with negative implications for various parts of the value chain (consumers, processors, etc.) requiring high quality raw materials. Adoption of post-harvest practices was studied at Jashpur district of Chhattisgarh. Majority of the respondents (61.67%) have medium level of adoption of post-harvest management practices for rice, followed......

Keywords: Rice farming, tribal farm families, adoption and post-harvest management activities.

ABSTRACT: This study assessed the efficacy of Natu Choline DS, a natural herbal choline replacer, in enhancing growth, liver health, and cost-efficiency in commercial pigs. Thirty-six weaned crossbred piglets were randomly assigned to three dietary treatments: control (no choline), choline chloride (60%) at 1 kg/ton, and Natu Choline DS at 150 g/ton feed. The trial lasted 90 days. Parameters recorded included body weight, feed conversion ratio (FCR), liver enzymes, backfat thickness.....

ABSTRACT: Background: Rice (Oryza sativa L.) is crucial for global food security, especially in Angola, where its production growth has experienced very little growth despite rising consumer demand. Enhancing rice productivity in the country requires development and adoption of rice varieties well-adapted to local environmental conditions. Therefore, this study evaluated three rice varietiesto the central-southern coast of Angola. Materials and Methods: A randomised block design with three replicates was used to test three rice varieties —Chilahila, Limpopo, and Sertaneja — over 2017-2018 growing season. Crops were cultivated in plots measuring 11m x 6m with......

ABSTRACT: Agriculture remains the primary source of livelihood and food security for smallholder crop farmers in South Africa’s Limpopo Province. However, this sector is increasingly threatened by climate change, prompting farmers to adopt various adaptation strategies. This study investigates the socioeconomic factors influencing climate adaptation strategies among small-scale tomato and avocado farmers across three districts: Capricorn, Vhembe, and Mopani. Using a multistage sampling technique, data were collected from 156 respondents through structured questionnaires....

ABSTRACT: Background: Vesicular stomatitis (VS) is one of the most relevant viral enzootic diseases of the livestock in the tropical and subtropical regions of the Americas. The VS disease in Brazil is caused mainly by Vesiculovirus Alagoas (VSAV), a member of the Vesiculovirus genus from the Rhabdoviridae family. The VSV is an arbovirus, enveloped, bullet-shaped containing a non-segmented, RNA negative sense genome. The VSAV is epitheliotropic, provokes proliferative skin and mucosal lesions as blisters- like vesicles, hypersalivation, erosion and ulcers around the mouth, tongue....

ABSTRACT: "Fruit-based agroforestry systems, integrating fruit trees with crops and/or livestock, present a multifunctional strategy to address pressing global challenges, including climate change, biodiversity loss, soil degradation, and economic insecurity. This review examines their potential through a comprehensive analysis of ecological, agronomic, and socio-economic benefits, drawing upon global case studies such as India’s traditional home gardens, Central America’s shade-grown coffee systems, and Africa’s Faidherbia albida parklands. Findings reveal that these systems enhance carbon sequestration, with tree biomass significantly increasing storage capacity over time. They support biodiversity through habitat creation and genetic diversity conservation. Soil health is bolstered....

ABSTRACT: Background: Dendrobium orchids are among the most commercially valuable ornamental plants due to their vibrant floral diversity and horticultural appeal. However, conventional propagation methods, including seed germination and shoot division, remain inefficient for mass production. Somatic embryogenesis offers a promising alternative by enabling rapid in vitro propagation of genetically uniform and disease-free plantlets. This study aimed to identify the optimal combination of 2,4-dichlorophenoxyacetic acid (2,4-D) and sucrose concentrations to induce somatic embryogenesis in Dendrobium sp. explants.
