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 determine the effect of shallot (Allium ascalonicum) sliced ​​water on the quality of bean (Phaseolus vulgaris) seed germination. The study was conducted with two treatments, namely seeds soaked in plain water (control) and seeds soaked in shallot sliced ​​water for 8 hours. The results showed that seeds soaked in shallot water had a better germination percentage, growth rate, and root and shoot length than the control. Shallot sliced ​​water has been proven to contain natural growth stimulants that can improve the quality of seed germination organically.

Abstract

Water deficiency is one of the major abiotic factors that significantly affects the growth and productivity of rice (Oryza sativa L.). Insufficient water availability disrupts vital physiological processes such as nutrient absorption, translocation, and distribution from roots to plant tissues. This study aims to analyze the effects of water shortage on the nutrient transport mechanism in rice plants. The methods included observations of soil moisture content, leaf nutrient levels, and transpiration rates under various drought treatments. The results revealed that water deficiency significantly reduced the roots’ ability to absorb essential macronutrients such as nitrogen (N), phosphorus (P), and potassium (K), due to decreased mass flow and ion diffusion in the soil. Furthermore, the reduction in turgor pressure and xylem activity disturbance inhibited the upward transport of nutrients, leading to lower vegetative growth and yield. Overall, this study emphasizes that optimal water availability is a key factor in maintaining nutrient transport efficiency and rice productivity, providing a scientific basis for developing adaptive irrigation strategies under drought conditions.
