Abstract

Celery (Apium graveolens L.) is a horticultural crop that is consumable and offers numerous health benefits. The purpose of this study was to ascertain how celery growth and yield cultivated on alluvial soil were affected by the interaction between liquid organic NPK fertilizer and chicken manure. The study utilized a field experiment that was designed completely randomized comprising two factors. The first factor was the dosage of chicken manure with three levels: C1: 50 g/pot, C2: 100 g/pot, and C3: 150 g/pot. The second factor was liquid organic NPK fertilizer with three levels: L1: 1%, L2: 2%, and L3: 3%. All treatment combinations were performed in triplicates. The results indicated that the interaction between chicken manure and liquid organic NPK fertilizer significantly affected the number of tillers and dry weight of celery yield. Chicken manure as a single factor significantly influenced the number of stems and tillers. Liquid organic NPK fertilizer as a single factor significantly influenced the number of tillers, fresh weight, dry weight, and plant height. The combination of chicken manure and liquid organic NPK fertilizer (C1L3) produced the highest number of stems per clump (79.44 stems) and the highest number of tillers per clump (9.78 tillers). The combination of C2L3 yielded the highest fresh weight (184 g) and dry weight (17.33 g). Keywords: Alluvial soil, Celery, Chicken manure, Liquid organic NPK fertilizer

Abstract

Soybean (Glycine max L.) production in Indonesia faces persistent challenges, with productivity declining from 16.70 quintals/ha in 2021 to 14.56 quintals/ha in 2023. Alluvial soils in West Kalimantan, encompassing approximately 1,495,033 ha, present opportunities for soybean expansion but are constrained by low pH, poor nutrient availability, and suboptimal biological activity. This study investigated the combined effects of arbuscular mycorrhizal fungi (AMF) inoculation and moringa (Moringa oleifera) leaf extract application on soybean growth and productivity on alluvial soil. A factorial completely randomized design was employed with AMF doses (0, 5, and 10 g/polybag) and moringa leaf extract volumes (150, 200, and 250 ml polybag⁻¹ at 20% v/v), replicated three times. Two-way factorial ANOVA showed significant main effects and significant interaction effects (M×E) between AMF and moringa extract for all measured variables (P < 0.05 or P < 0.01). The combination of AMF at 10 g/polybag with moringa extract at 250 ml/polybag (M₂E₃) produced optimal results with 97.2 pods/plant and 48.6 g seed dry weight (DW) per plant, representing increases of 129% and 191% over the non-mycorrhizal lowest-dose control (M₀E₁), respectively. These findings suggest that integrated application of AMF and moringa extract represents a promising strategy for improving soybean productivity on marginal alluvial soils, pending field-scale validation.
