Abstract

This study was conducted to determine the effect of compost and vermicompost from market organic waste on the soil chemical properties and the growth of maize. The treatments tested were three doses of compost (2.5, 5, and 10 t/ha), three doses of vermicompost (2.5, 5, and 10 t/ha), and one control (without compost or vermicompost). At the time of harvest (10 weeks after planting), maize shoot dry weight, root dry weight, cob length, cob diameter, cob with husk, and cob dry weight, as well as the soil chemical properties organic carbon (C), total nitrogen (N), total phosphorus (P), available P, total potassium (K), and pH were observed. Maize plant height, leaf number, and stem diameter were observed at 2, 4, 6, and 8 weeks after planting. The results showed that the application of compost and vermicompost significantly affected soil chemical properties and the yield of maize. The application of 10 t vermicompost/ha resulted in the highest yield of maize and highest increase of soil organic carbon, total phosphorus available phosphorus, total potassium, and pH by 7.21%, 112.41%, 287.44%, 85.44% and 17.58%, respectively. The application of 10 t compost/ha resulted in the highest increase of soil total N by 44%.

Abstract

The objective of this research was to evalu-ate the tolerance of peanut lines generated from Gamma ray iradiation against polyethylene glycol (PEG) solution stress. The peanut lines seeds of mutan M3 generation were used in this experiment. Peanut plants of cv. “Local Bima” were also tested as control plant. The mutan and control peanut plants were planted on rice hush charcoal medium. The peanut plants that 15 to 50 days old were watered with PEG 15% solution (0.41 Mpa osmotic potential = drought stress). Identification of tolerant peanut lines on PEG stress were calculated with using drought sensitivity index value (S) on observed parameter and proline content. Results of the experiment showed that peanut line G300 was classified as moderate tolerant to PEG solution stress with the highest proline content. Keywords : peanut lines, gamma ray, mutan, polyethylene glycol

Abstract

Background:  Soil biodiversity is a key element of terrestrial ecosystems that underpins their resilience to environmental stress, especially amid accelerating climate change. Among soil organisms, earthworms are vital ecosystem engineers that regulate soil structure, nutrient cycling, and organic matter decomposition. However, intensive land use and climatic pressures have led to declining soil biodiversity, threatening ecosystem stability and sustainable land management. Methods: This review synthesizes recent empirical and experimental studies on the dual roles of earthworms in carbon and nitrogen cycling, soil organic carbon (SOC) accumulation, and greenhouse gas (GHG) fluxes under different management systems. Findings: The analysis emphasizes conservation tillage, organic amendments, and precision nutrient management as key strategies influencing earthworm-mediated processes. Evidence shows that earthworm activity can increase nitrous oxide (N₂O) emissions by up to 42% in nitrogen-enriched soils. Conversely, interactions with organic amendments such as compost and biochar can enhance SOC by up to 32.69%. Conservation tillage, particularly strip tillage, improves carbon sequestration (1.21 Mg C ha⁻¹ year⁻¹) and increases earthworm abundance by up to 133%. These results demonstrate that management practices strongly mediate the balance between earthworm-driven GHG emissions and carbon storage. Conclusion: Earthworms are central to sustainable agriculture through their roles in improving soil quality and mitigating climate impacts. Implementing earthworm-friendly practices, such as reduced tillage, organic matter addition, and balanced nutrient application, can optimize their ecological benefits while minimizing GHG emissions. Novelty/Originality of this article: This review provides an integrative perspective on the paradoxical function of earthworms as both GHG emitters and climate mitigators. It offers a conceptual framework to guide future research on enhancing carbon sequestration and sustainability through earthworm-based soil management.
