    Smart farming involves the integration of information and communication technologies into machinery and sensors for use in agricultural systems. It is expected to potentially enhance the sustainability of agriculture and global food security. The need for smart farming arises from the increasing adverse environmental, ecological, social, and economic impacts on food systems. The potential impact of smart farming solutions on different countries is less known. Therefore, we comprehensively analyzed the role of smart farming solutions in sustaining agricultural production in the context of comparing a developed (Republic of Korea), and an emergent (Republic of Uganda) country. We scrutinized the agricultural assets, natural resources, approaches, technologies, policy interventions, achievements, challenges encountered, and reasons of smart farm pursuit for each country. Information presented in the paper indicated that both countries have similar objectives in the pursuit for smart farming: response to climate change and sustaining food security. However, the Republic of Korea employs a holistic approach of revolutionizing agriculture via smart farms. In contrast, distinct smart farming interventions implemented by government institutions, competing private sector, and non-governmental organizations are shaping the development of a smart farm concept in the Republic of Uganda. In conclusion, the application of smart farming solutions appears to be promising in enhancing the stability of the whole food system in both countries.

    In vitro multiplication and phytochemical evaluation of Apios americana Medik for enhanced production of the staple food and tissues with versatile bioactivities.

    Apios americana Medik tissues, including tubers, flowers, leaves, and vines have both nutritional and therapeutic benefits. These tissues are extensively used in products like beverages and food supplements, driving an exponential increase in worldwide demand for the plant. However, conventional propagation of A. Americana through seeds and tubers faces several challenges, including limited seed sets under manual pollination, resulting in reduced production. To overcome these challenges, micropropagation emerges as a promising solution. The current research study has developed an effective in vitro propagation strategy for A. americana using direct regeneration from apical segment explants. Full-strength Quoirin and Lepoivre (QL) medium, supplemented with vitamins and 2.0 mg/L benzylaminopurine (BAP), yielded the highest number of shoots (7.50 ± 0.06) per apical segment explant. QL medium fortified with 1.0 mg/L indole-3-butyric acid (IBA) demonstrated the highest root number (2.80 ± 0.30), length (85.80 ± 7.49 mm), and surface area (10.40 ± 0.82 cm2) in regenerated A. American shoots. The survival rate of the regenerants in the ex-vitro environment was 92.7% after acclimatization. In vitro-regenerated A. Americana plants and mother plants exhibited similar ploidy levels, chlorophyll content, photosynthetic rate, phytochemical composition, and antioxidant capacity, indicating similarity in their physiological and biochemical properties. This protocol offers a rapid and scalable method for generating high-quality, A. Americana plant stocks with stable genome size/ploidy level, meeting the exponentially growing demand for plant tissues. Additionally, it holds potential applications in A. Americana breeding and germplasm preservation.
