Abstract

Background: The study of air-soil coupling is crucial for agricultural lands such as Tarnab since it provides valuable insights into microbial dynamics, soil ventilation, and the biogeochemical cycle. In addition to this, the floods of 2010 (which also affected the Tarnab) add more value to this work. Governing the air-soil coupling is mandatory for providing the vital oxygen for the roots. Aim: In this research, the regression equations linking the seasonal daily average air temperature and seasonal daily average soil temperature have been established for Tarnab. Methods: The data of daily maximum/minimum air temperature and soil temperatures (8 am/5 pm), which have been regularly recorded at the Agriculture Research Institute Tarnab from 1996 to 2023, have been used to find the regression. Results: The average maximum temperature correlates strongly with 5 pm soil temperature in MAM (R2=0.4453] and DJF (R2=0.4995) with 26.75(95% CI: 23.04, 30.77) and 14.28(95% CI: 7.30, 18.83) confidence intervals, respectively and n=28. The R2 for the SON is fairly strong for the relationship between maximum temperature and 5 pm soil temperature, as well as minimum temperature and soil temperature at 8 am, with values 0.1748 {25.96[95% CI: 20.83, 29.43]} and 0.2872 {19.11[95% CI: 14.78, 22.18]}, respectively. Conclusion: Air temperature has shown an influence on soil temperature, besides some irregular behaviour.

Abstract

Background: The agricultural sector faces several challenges, including low productivity, high production costs, and unsupportive policies, which hinder the sector's full potential. This article examines the roles of technology, government policy, and institutions in promoting agricultural development, based on a literature review of the book Economics of Development by Perkins et al. (2013). Aim: This study aims to elucidate the importance of agricultural sector growth and modernization. Methods: This review employs the Literature Review method, drawing upon various scholarly sources related to Agricultural Development and other relevant literature to serve as references and comparative material for the discussion. Results: The review finds that technological innovation and institutional capacity consistently emerge as the most decisive mechanisms for agricultural modernization, while policy effectiveness shows mixed evidence across different contexts. Although there is broad agreement that agricultural growth strongly contributes to poverty reduction, divergence remains regarding the extent to which trade liberalization benefits smallholder farmers. Conclusion: Therefore, an integrated policy approach, the use of appropriate technologies, and the strengthening of institutional frameworks are essential strategies to maximize the agricultural sector’s contribution to economic development and poverty alleviation.

Abstract

Background: Stingless bee honey presents a high-value niche within sustainable agrifood systems, yet small-scale agripreneurs face structural constraints in marketing, certification, and digital engagement that impede inclusive competitiveness. Aim: This study formulates sustainable marketing strategies to empower stingless bee honey agripreneurs in Samarinda, East Kalimantan, thereby enhancing market access, firm-level resilience, and socio-ecological sustainability. Methods: Employing a convergent mixed-methods design, primary data were collected between July and September 2025 through 27 semi-structured interviews, three focus group discussions (FGDs), direct observation, and structured questionnaires involving 65 agripreneurs, eight cooperative leaders, and six local government or institutional stakeholders. Participants were selected using a purposive sampling strategy to ensure representation across enterprise scales and cooperative membership. Internal and external determinants were assessed using IFE and EFE matrices; results were integrated via IE and SWOT frameworks to derive strategy clusters. Results: The IFE (score = 2.86) and EFE (score = 2.93) positions indicate a “Growth and Build” strategic posture. Four strategy clusters emerged: SO (eco-branding, certification, tourism linkages, e-commerce expansion), WO (digital literacy, quality assurance, managerial capacity building, inclusive finance), ST (value-chain diversification, R&D partnerships, sustainability differentiation, cooperative logistics), and WT (community microfinance, joint marketing, insurance/risk-sharing, partnership models). Triangulation of qualitative and quantitative findings strengthens the validity of these strategic priorities. Conclusion: Integrating sustainability principles with digital marketing and cooperative governance offers a viable pathway for transforming stingless bee honey firms into resilient, inclusive agribusinesses. Policy and institutional support that bolsters access to certification, digital capacity, and cooperative finance are pivotal in translating ecological strengths into competitive market outcomes.

Abstract

Background: Entisol soil in the coastal area of ​​Bengkulu has low fertility with limited organic matter and nutrient contents, so it requires soil amendments to increase plant productivity. Aim: This study aims to evaluate the effectiveness of rice husk biochar on improving soil chemical properties and increasing sweet corn (Zea mays saccharata) yield. Methods: The experiment was conducted on a polybag scale (10 kg of soil per polybag) using a Completely Randomised Design (CRD) with four doses of rice husk biochar (0, 5, 10, and 15 t/ha), with each treatment repeated six times. Biochar was produced through indirect pyrolysis at a temperature of approximately 400 °C, incubated for four weeks, and applied to the soil at 50% of the recommended fertilizer dose. Results: The analysis results showed that the application of rice husk biochar had a significant effect (p < 0.05) on increasing soil pH, organic carbon (C), total nitrogen (N), and cation exchange capacity (CEC). A dose of 10 t/ha increased soil pH from 6.01 to 6.61, organic C from 2.09% to 2.81%, total N from 0.11% to 0.17%, and CEC from 4.98 to 5.64 cmol(+)/kg, significantly higher than the control (p < 0.05). This increase in fertility directly impacted the growth and yield of sweet corn, with cob weight reaching 437.5 g, significantly greater than the control at p < 0.05, but not significantly different from the dose of 15 t/ha. Conclusion: Thus, rice husk biochar at a dose of 10 t/ha effectively improves Entisol soil quality and increases sweet corn yields, and has the potential to be applied as a sustainable agricultural innovation in tropical marginal lands.
