Abstract

This study aimed to analyze the effect of shading on the growth and photosynthetic rate of red chili pepper (Capsicum annuum L.). The results showed that shading treatment had a significant effect on morphological parameters, namely plant height and total dry weight, but did not significantly affect leaf width, leaf number, and leaf length compared to plants grown without shading. Physiologically, shading influenced quantum yield, photochemical quenching, and non-photochemical quenching, whereas the maximum photosynthetic rate (Pmax) did not show a significant difference. From an ecophysiological perspective, shading treatment significantly increased proline and ascorbic acid contents. These findings indicate that red chili pepper exhibits a high adaptive capacity to low light intensity conditions. This study is expected to contribute as a reference material and learning resource in the fields of plant physiology and plant biology.

Abstract

The soil’s ability to store water is one of the key factors determining agricultural productivity, particularly in lowland areas that frequently experience water saturation. This study aimed to examine the effects of soil texture and structure on the soil’s water-holding capacity. Soil samples were collected from several points in lowland areas and subsequently analyzed in the laboratory using the pipette method to determine soil texture, morphological observations to assess soil structure, and the gravimetric method to measure water-holding capacity. The results showed that fine-textured soils, such as clay, have a higher water-holding capacity compared to coarse-textured soils, such as sand. Soil structures that are granular and stable enhance soil porosity and enable water to be retained for a longer period. The combination of clay texture and granular structure resulted in the most optimal soil water-holding capacity. Therefore, soil physical conditions, particularly texture and structure, play a crucial role in maintaining soil water balance. Soil management practices involving the addition of organic matter and appropriate tillage are essential measures to improve soil water-holding capacity and support sustainable agriculture in lowland areas.

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.

Abstract

Nitrogen is an essential nutrient that plays an important role in chlorophyll formation and photosynthesis. This study aimed to determine the effect of nitrogen fertilization on photosynthesis rate, chlorophyll content, and growth of maize (Zea mays L.). The research was conducted from October to December 2025 in Dahana Village, Universitas Nias, using a Completely Randomized Design (CRD) with four nitrogen levels and five replications. Observed parameters included plant height, number of leaves, and plant dry weight. Data were analyzed using analysis of variance (ANOVA) and LSD test at the 5% level. The results showed that nitrogen fertilization significantly affected maize growth by increasing plant height, leaf number, and dry weight. However, excessive nitrogen application did not always result in optimal growth. Therefore, appropriate nitrogen fertilization is required to support optimal maize growth.
