Abstract

An inventive way to raise farmers' knowledge and proficiency in rural regions is through digital-based agricultural extension. The purpose of this study is to evaluate the extension program's effectiveness and how it affects farmers' satisfaction. 50 farmers participating in the initiative were given questionnaires and conducted in-depth interviews as part of the methodology. According to the findings, 75% of farmers learned new skills and 82% of farmers gained more information; on a Likert scale of 5, the average satisfaction level was 4.2. Technology adoption is nevertheless hampered by issues including low digital literacy and inadequate internet infrastructure, despite the program's effectiveness. According to the study's findings, enhancing digital literacy and building infrastructure are critical to the long-term viability of Indonesia's digitally based extension initiatives.

Abstract

This study aims to optimize nitrogen fertilization in corn (Zea mays) to increase yields on marginal land. Marginal land often experiences nutrient deficiencies, especially nitrogen, which have a negative impact on plant growth and productivity. In this study, an experiment was conducted using a Randomized Block Design (RBD) involving five nitrogen fertilizer dose treatments, namely 0 kg N/ha (control), 75 kg N/ha, 150 kg N/ha, 225 kg N/ha, and 300 kg N/ha. The parameters observed included plant height, stem diameter, leaf area, fresh weight of cobs, and yield. The results showed that nitrogen fertilization significantly increased all growth parameters and yields of corn. The highest dose (300 kg N/ha) produced an average plant height of 180 cm, stem diameter of 4.5 cm, leaf area of ​​550 cm², fresh weight of cobs of 0.9 kg, and yields reaching 8 tons/ha. These findings support the hypothesis that increased nitrogen availability positively contributes to vegetative growth and yield of corn. This study provides practical recommendations for farmers to apply nitrogen fertilization optimally on marginal land to increase corn productivity. Further research directions are suggested to explore the long-term effects of nitrogen fertilization and the combination of organic and inorganic fertilizers for agricultural sustainability.

Abstract

To support environmentally sound agricultural practices, this study assessed the effectiveness of a single type of organic fertilizer applied at different dosage levels in optimizing the yield of groundnut (Arachis hypogaea L.). The methodology involved a Completely Randomized Design (CRD) field trial structured around four treatments: a control and three compost dosage levels, each executed in triplicate. Key performance indicators included plant morphological traits (height and number of pods) and harvest parameters (fresh pod weight and yield per hectare). Data analysis confirmed that all organic fertilizer applications led to statistically significant increases in groundnut growth and yield when compared to the untreated control. The highest dosage treatment (30 tons/ha) produced the most favorable outcome, with a fresh pod yield of 615 g/m². These improvements are attributed to the compost’s ability to enhance soil physical, chemical, and biological properties. This research supports the use of organic fertilizer as a sustainable strategy to improve groundnut productivity while maintaining environmental quality.

Abstract

Water plays a crucial role in agricultural productivity and food security, particularly in irrigated rice farming systems. However, seasonal water shortages and inefficient water management often reduce crop yields in several irrigation areas. This study aimed to evaluate irrigation water use efficiency in the Antokan Irrigation Area, Nagari Manggopoh, Agam Regency, West Sumatra, to support more effective water management strategies. The evaluation was conducted through field measurements of irrigation discharge and channel efficiency, combined with calculations of irrigation water requirements based on consumptive use, land preparation needs, percolation losses, and effective rainfall. Water balance analysis was also applied to assess the adequacy of water supply. The results showed that water availability in the Namuang Saiyo irrigation channel reached 0.061 m³/s, while the total irrigation water requirement was 0.051 m³/s. The irrigation channel efficiency was 94.81%, indicating good hydraulic performance and minimal conveyance losses. The overall irrigation water use efficiency reached 83.29%, classified as efficient. These findings indicate that the Antokan irrigation system is capable of meeting crop water requirements optimally and can serve as a reference for improving irrigation management in similar agricultural areas.
