Community Service Outreach on Utilizing Rice Fields for Mustard Green Cultivation Before the Paddy Harvest Period

Abstract

This community service program addressed the underutilization of rice fields during the idle period before the main paddy harvest. This phase is often left unproductive in many rural farming systems despite its potential for short-cycle crop cultivation. The primary objective of this program was to introduce mustard green (Brassica juncea) cultivation as an intercropping solution to maximize land use and increase farmers’ income without disrupting rice production. The outreach activity occurred in Banyuasin Regency and involved collaboration between university students, academic supervisors, and local farmers. The method involved a series of participatory activities, including organic fertilizer preparation, field spraying, mustard green planting, and growth inspection. Field demonstrations and informal discussions were used to transfer technical knowledge effectively. The results showed healthy mustard green growth, rapid crop cycles (within 3–4 weeks), and strong community interest in adopting the practice. Farmers responded positively due to the low cost, environmental friendliness, and potential for income diversification. The novelty of this program lies in its practical integration of short-cycle crops into existing rice-based systems using sustainable techniques and community-centered implementation. Unlike conventional monoculture outreach, this initiative empowered local communities through joint knowledge creation and field-based learning. In conclusion, this community service effort presents a scalable model for sustainable land optimization that enhances agricultural resilience, food diversity, and farmer livelihoods, particularly in rural rice-producing regions.
