Abstract

This study aims to examine the relationship between soil physical properties and plant resistance to diseases. Soil physical properties, such as texture, density, and water-holding capacity, significantly influence plant health and their susceptibility to pathogen attacks. Using experimental methods involving the measurement of soil parameters and analysis of plant responses to various diseases, the results indicate that soils with optimal texture and aeration contribute to reduced infection rates. These findings suggest that proper management of soil physical properties can enhance plant resistance, providing important implications for sustainable agricultural practices. The study advocates for an integrated approach to soil management to improve plant resilience against diseases, ultimately leading to increased agricultural productivity.

Abstract

The use of differential equations in plant growth is an effective mathematical approach to describe and model the dynamics of plant growth. Differential equations are used to depict changes in plant size and biomass over time, considering factors such as water availability, light, temperature, and nutrients. These models help in predicting agricultural yields, gaining deeper insights into plant physiological processes, and optimizing cultivation practices. By utilizing differential equations, researchers can develop more accurate plant growth models, which are useful in natural resource management and increasing agricultural productivity

Abstract

This study aims to determine the effect of light intensity on the photosynthetic rate and growth of spinach plants (Amaranthus sp.). The research was conducted experimentally using a Completely Randomized Design (CRD) with one treatment factor: light intensity consisting of four levels—100% (P1), 75% (P2), 50% (P3), and 25% (P4) of natural sunlight. Observed parameters included photosynthetic rate, plant height, number of leaves, leaf area, fresh weight, and dry weight. The results showed that light intensity significantly affected all observed variables. The highest photosynthetic rate (18.5 μmol CO₂/m²/s), plant height (22.4 cm), number of leaves (18), fresh weight (35.2 g), and dry weight (5.7 g) were obtained under full sunlight (P1). In contrast, the lowest values were recorded under 25% light intensity (P4). It can be concluded that higher light intensity enhances photosynthetic activity and vegetative growth of spinach plants significantly. Therefore, managing appropriate light levels is crucial for optimal spinach cultivation, especially in controlled or indoor farming systems.
