Abstract

The next step after designing the composter is to test the performance of the composter. It is very important to observe the composting process find out the optimum type of composter to use both in the rate of composting and the compost produced. The aims of this research was to compare aerobic and anaerobic composters on composting rates and the compost. The method used was quasi-experimental by comparing the performance of the composter both in terms of composting speed, temperature, humidity, degree of acidity, color and smell of the compost. The results showed that anaerobic composting had a better rate (12 days) than the aerobic method (25 days). The composting process using an aerobic composter required a slightly higher temperature (36oC) than an anaerobic composter (32.5oC). The composting process using an aerobic composter has an average humidity value of 60.75 while that of an anaerobic composter is 68.54. Anaerobic composter showed almost the same value as the aerobic method for the degree of acidity. In terms of odor and color measurements, anaerobic composters produced a more pungent odor and a blackish brown color.

Abstract

This extension program focuses on exploring business opportunities for farmer-entrepreneurs in horticultural plant nurseries, utilizing cutting and grafting techniques to serve local markets. The initiative aims to enhance farmers' technical skills, market understanding, and business management capabilities in plant propagation. Through participatory training methods, including hands-on demonstrations and mentoring sessions, participants acquired practical knowledge of vegetative propagation techniques with demonstrated success rates of 80-90%. Market analysis revealed strong local demand for fruit seedlings (particularly citrus, mango, and guava) and ornamental plants, offering profit margins of 40-60%. Key challenges identified include limited access to capital, price fluctuations, and competition from imported seedlings. The program proposed solutions such as improved financing access, strengthened marketing networks, and quality certification systems. Post-intervention results showed significant improvements: 30-50% increase in production capacity, expanded market connections, and 20-40% income growth among participants. The program effectively enhanced both technical competencies and business acumen, creating sustainable livelihood opportunities in the horticultural nursery sector. Recommendations include establishing government-agriculture department partnerships, developing digital marketing platforms, and implementing continuous mentoring programs to ensure long-term business sustainability. These findings highlight the potential of vegetative propagation techniques in empowering small-scale nursery entrepreneurs while contributing to local agricultural development.
