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 using coconut husk soaking water as a watering medium on the growth of celery plants (Apium graveolens). Coconut husk soaking water is known to contain various nutrients such as potassium, magnesium, and natural growth hormones that can support plant development. The research was conducted using an experimental method with a randomized block design (RBD), consisting of two main treatments: watering with plain water (control) and watering with coconut husk soaking water. Observed parameters included plant height, number of leaves, and leaf color over a specific growth period. The results showed that celery plants watered with coconut husk soaking water exhibited better growth compared to the control, particularly in terms of leaf number and greener leaf color. These findings indicate that coconut husk soaking water has the potential to serve as a natural watering alternative that can enhance soil fertility and the quality of celery plant growth. Thus, utilizing coconut husk waste in the form of soaking water can be an environmentally friendly solution for sustainable agricultural practices.

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.
