Abstract

Liquid organic fertilizer (LOF) is increasingly utilized as an organic-based agricultural input to support environmentally sustainable crop production. The presence of nutrients in soluble form enables LOF to enhance vegetative growth during the early stages of plant development. This study assessed the vegetative response of long bean (Vigna unguiculata subsp. sesquipedalis) to LOF application using plant height and leaf number as growth parameters. The experiment was conducted from October to November 2025 at an agrotechnology practicum field characterized by relatively uniform environmental conditions. A Completely Randomized Design (CRD) was applied with three treatments, namely no LOF application, LOF at a rate of 20 mL per plant, and LOF at 40 mL per plant, each replicated three times. The collected data were analyzed using analysis of variance at a 5% significance level, followed by the Least Significant Difference test. The results revealed that different LOF application rates significantly affected vegetative growth of long bean plants. The application of LOF at 20 mL per plant resulted in the highest mean plant height (25.5 cm), which was significantly greater than that of the control (18.0 cm) and the 40 mL treatment (21.0 cm). A similar trend was observed for leaf number, where the 20 mL treatment consistently produced higher values than the other treatments. These findings indicate that LOF applied at a rate of 20 mL per plant is the most effective dosage for promoting early vegetative growth of long bean.

Abstract

Tomato (Solanum lycopersicum L.) is an important horticultural crop that requires high-quality seeds to achieve optimal growth and development. One approach to improving the physiological quality of seeds is organic priming using environmentally friendly natural materials. Moringa (Moringa oleifera L.) leaves contain various bioactive compounds, including cytokinins, auxins, vitamins, minerals, and antioxidants, which have the potential to enhance seed germination and vigor. This study aimed to evaluate the effect of organic priming with moringa leaf extract on tomato seed germination and vigor and to determine the most effective extract concentration. The experiment was conducted at the Laboratory of Weetabula Catholic University from April to May 2026 using a Completely Randomized Design (CRD) with a single factor consisting of moringa leaf extract concentrations: P0 (0%), P1 (25%), P2 (50%), P3 (75%), and P4 (100%), with four replications. Tomato seeds were soaked in the extract solutions according to the treatments for 12 hours and subsequently germinated using the rolled paper test method. The observed variables included germination percentage, germination rate, vigor index, primary root length, plumule length, and seedling fresh weight. Data were analyzed using analysis of variance (ANOVA) at the 5% significance level, followed by the Least Significant Difference (LSD) test at the 5% level. The results showed that organic priming with moringa leaf extract significantly affected all observed parameters. The P3 treatment (75% extract concentration) produced the best results, with a germination percentage of 96.25%, germination rate of 22.08% day⁻¹, vigor index of 89.50, primary root length of 5.95 cm, plumule length of 7.43 cm, and seedling fresh weight of 0.69 g. The P3 treatment did not differ significantly from P2 (50%) but differed significantly from P4 (100%), P1 (25%), and P0 (control). Therefore, moringa leaf extract at a concentration of 75% was the most effective treatment for improving tomato seed germination and vigor and has potential as an inexpensive, environmentally friendly, and sustainable seed enhancement technology
