Abstract

This research was carried out to determine how liquid organic fertilizer (LOF) produced from agricultural waste influences watermelon (Citrullus lanatus) production among members of the Mangele Farmers' Group in Teluk Belukar Village. A field trial was set up to contrast crops grown without any LOF input, serving as the control, against crops given LOF derived from farm waste. Fruit diameter and fruit weight recorded at harvest time became the two indicators tracked throughout the trial. All data were processed through descriptive statistics, with mean values calculated for each indicator and arranged into tables to allow the two groups to be compared side by side. Findings revealed that watermelon output responded positively to LOF application: fruits under the LOF treatment averaged 58.0 cm across, compared with only 34.0 cm for the control group, while average fruit mass reached 3.68 kg under LOF versus 2.24 kg without it. Such outcomes suggest that fertilizer produced from agricultural residue can supply nutrients more efficiently, which in turn assists the fruit-forming and fruit-enlarging stages of growth. Consequently, LOF sourced from farm waste offers a promising, environmentally sound fertilization option for boosting watermelon yields while simultaneously putting agricultural waste to productive, sustainable use.

Abstract

Fertilization is a crucial aspect in increasing the productivity of soybean (Glycine max L.), both in terms of vegetative growth and yield. Organic fertilizers, such as compost and manure, play a long-term role in improving the physical, chemical, and biological structure of the soil, increasing microbial activity, and gradually supporting nutrient availability (Widodo et al., 2018; Yang et al., 2004). Meanwhile, inorganic fertilizers such as urea, NPK, and SP-36 provide nutrients quickly and efficiently, thereby accelerating plant growth and increasing yields in a relatively short time (Putra Manik et al., 2019). However, excessive use of inorganic fertilizers can lead to decreased soil fertility and environmental pollution (Nugroho et al., 2017). Several studies indicate that the combination of organic and inorganic fertilization can create synergy that increases nutrient uptake efficiency, improves soil quality, and supports sustainable plant productivity (Migunansyah, 2009; Khaerunisa, 2013). Therefore, an integrated fertilization strategy is highly recommended in an environmentally friendly soybean cultivation system.
