Abstract

This study aimed to describe the application of an intercropping system between sweet corn (Zea mays var. saccharata Sturt) and tomato (Solanum lycopersicum L.) practiced by farmers in Dahana Tabaloho Village. The research employed a descriptive case study approach. Data were collected through field observations, farmer interviews, and documentation of cultivation activities. The observed aspects included planting patterns, planting spacing, crop maintenance, fertilization, pest and disease management, and crop yields obtained by farmers. The results indicated that the intercropping system provided more efficient land utilization compared to monoculture systems by allowing two commodities to be cultivated simultaneously on the same land area. Furthermore, the system has the potential to improve land-use efficiency, diversify crop production, and increase farmers' income. However, challenges were identified, particularly competition among plants for light, water, and nutrients when planting arrangements were not properly managed. Therefore, the intercropping system of sweet corn and tomato in Dahana Tabaloho Village can serve as an effective land management alternative to enhance agricultural productivity and farming sustainability.

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.
