Abstract

This research is an experimental study with a qualitative approach aimed at determining the effect of banana peel water concentration on the germination of corn seeds. The study was conducted in Hilimbaeodesolo, Gunungsitoli City, over four days using three different treatments: 25%, 50%, and 100% concentrations of banana peel water, each repeated three times. The seeds were soaked for 36 hours, and observations were made on the emergence of radicles, the number of germinated seeds, and signs of decay. The results showed that the 50% concentration was the most effective treatment, producing healthy sprouts and the highest number of germinated seeds. The 25% concentration showed limited early growth, while the 100% concentration caused the seeds to rot due to excessive fermentation. The study concluded that banana peel water concentration affects germination success, with a balanced concentration (50%) being the most optimal to support early growth. It is recommended to use moderate concentrations and conduct further testing on plant growth after the germination phase.

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.
