Abstract

This research aims to analyze the relationship between soil structure and plant biomass production. Soil structure is an important factor that influences plant growth through its influence on aeration, drainage and nutrient availability. In this research, soil physical parameters were measured, such as density, porosity and aggregate size, as well as observations of plant biomass production in various types of soil. The analysis results show that soil with good structure, characterized by high porosity and low density, tends to produce higher biomass. Additionally, a significant positive relationship was found between soil aggregate size and the volume of biomass produced. These findings emphasize the importance of managing soil structure to increase crop productivity, as well as providing insights for sustainable agricultural practices. It is hoped that this research can become a reference for farmers and land managers in efforts to increase agricultural yields through improving soil structure.

Abstract

This study aims to explore the effect of lighting on plant growth and development. Two different lighting conditions, namely bright and dark places, were selected as independent variables in this study. The samples used in this study were mung bean and corn (Phaseolus vulgaris) plants. The selection of mung bean and corn plants as samples was based on several considerations, including: Mung bean and corn plants are easy to plant and care for, so they are suitable for research that requires intensive observation over a certain period of time. The results of the study showed that plants placed in bright places showed better growth compared to plants placed in dark places. Plants in bright places had higher plant heights, more leaves, and greater leaf weight. This shows that sufficient lighting is an important factor in supporting plant gowth. The conclusion of this study is that lighting plays an important role in plant growth. Adequate lighting can increase photosynthesis, which in turn supports plant growth and development. This study provides insight into the importance of lighting in agriculture and can be a basis for further research on optimizing lighting conditions for optimal plant growth.
