Abstract

Soil infiltration capacity is a critical factor in water management and soil conservation, particularly in agricultural systems and natural ecosystems. Effective infiltration allows water to penetrate the soil, reducing surface runoff, preventing erosion, and enhancing groundwater reserves. A key element influencing infiltration capacity is the presence and activity of soil microorganisms, which play a vital role in soil structure formation and aggregate stability. This study aims to analyze the role of soil microorganisms, including bacteria, fungi, and actinobacteria, in enhancing infiltration capacity through organic matter decomposition, aggregate formation, and the production of exopolysaccharides that bind soil particles. The findings demonstrate that soils with active microbial populations exhibit significantly higher infiltration capacity compared to soils with limited microbial activity. This is attributed to microbial processes that improve soil structure, increase porosity, and stabilize aggregates, facilitating water absorption. The study underscores the importance of sustainable agricultural practices that support microbial diversity to improve soil quality and ecosystem resilience. By highlighting the essential contributions of soil microorganisms to infiltration, this research provides insights into soil health management strategies that enhance water retention and soil conservation.

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.

Abstract

Yard-long bean (Vigna unguiculata L.) is an important horticultural commodity that requires optimal nutrition for maximum growth and production. This study aimed to determine the optimal dose of compost fertilizer that can improve the yield and quality of yard-long bean plants. The research was conducted using a Completely Randomized Design (CRD) with 5 compost fertilizer dose treatments: K0 (control), K1 (10 tons/ha), K2 (20 tons/ha), K3 (30 tons/ha), and K4 (40 tons/ha), each replicated 4 times. The observed parameters included plant height, number of leaves, pod length, number of pods per plant, pod weight per plant, and chlorophyll content. The results showed that compost fertilizer application significantly affected all growth and production parameters. Treatment K3 (30 tons/ha) gave the best results with an average plant height of 185.5 cm, 42.3 pods per plant, and pod weight of 245.7 g per plant. The highest chlorophyll content was also obtained in K3 treatment with a value of 48.2 SPAD. Application of compost fertilizer at a dose of 30 tons/ha is the optimal dose for improving the yield and quality of yard-long bean plants, with a production increase of 67.3% compared to the control.
