Abstract

This study aims to examine the differences in plant growth placed in bright and dark places. Light is one of the important factors in photosynthesis, which plays a direct role in plant growth and development. In this study, several plant samples from the same species were grown in controlled environmental conditions and placed in two different locations: a bright place with direct access to sunlight, and a dark place that did not receive any light at all. The parameters measured included plant height, number of leaves, and leaf color during a certain period. The results showed that plants placed in bright places had more optimal growth than plants in dark places. Plants in bright places showed a significant increase in height, a greater number of leaves, and fresh green leaf color. In contrast, plants in dark places tended to have stunted growth with pale or yellowish leaf color. This study confirms the importance of light as a key factor in plant growth, and provides insight into plant management in various environmental conditions.

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.
