Abstract

Epigenetics plays a crucial role in how plants adapt to environmental stressors such as drought, salinity, and extreme temperatures. Understanding the mechanisms behind epigenetic modifications can provide insights into plant resilience and survival strategies in changing environments. This study aims to investigate the role of epigenetic mechanisms in plant adaptation to various environmental stressors. By examining specific epigenetic modifications and their effects on gene expression, the research seeks to elucidate the pathways through which plants respond to stress. A combination of field experiments and laboratory analyses was employed to study epigenetic changes in selected plant species exposed to different environmental stress conditions. Techniques such as DNA methylation profiling and histone modification analysis were utilized to assess epigenetic alterations. Findings indicate that epigenetic modifications, including changes in DNA methylation and histone acetylation, play a significant role in regulating gene expression in response to stress. Certain stress-induced epigenetic changes were associated with enhanced tolerance to adverse conditions, suggesting a vital adaptive mechanism for plants. This research highlights the importance of epigenetics in understanding plant adaptation to environmental stress. The findings contribute to the growing body of knowledge regarding plant resilience mechanisms and may inform breeding programs aimed at developing stress-tolerant plant varieties

Abstract

This study designs, implements, and evaluates an autonomous robotic weeding system as a mechanical solution to reduce herbicide dependence in organic vegetable farming. Organic farming faces persistent weed management challenges due to restrictions on synthetic herbicides and rising labor costs. Weeds compete with crops for essential resources, resulting in yield losses and reduced efficiency. While mechanical weeding has been a viable alternative, traditional methods often lack precision and can harm crops. Recent advances in robotics and automation offer a solution by enabling intelligent, autonomous weed control that aligns with sustainable agricultural practices. The research uses a design-and-experimental methodology, developing an autonomous robotic platform equipped with vision-based sensors, navigation algorithms, and mechanical weeding tools. The system was tested in organic vegetable plots, and field trials measured weed removal efficiency, crop safety, operational accuracy, and energy consumption, with comparisons to traditional manual weeding methods. The results showed that the robotic system effectively reduced weed density with high precision while minimizing crop disturbance. The system demonstrated consistent performance across test plots and significantly reduced reliance on manual labor and chemical inputs. Weed control efficiency was comparable to traditional methods, with improved consistency and reduced operational fatigue. The study concludes that robotic weeding is a viable, sustainable solution for weed management in organic vegetable farming and offers promising implications for smart agriculture and technology-integrated education.
