Overuse of inorganic fertilizers can degrade soil quality, and chicken bone meal (CBM), a poultry by-product containing nitrogen, phosphorus, and calcium, is a potential organic alternative, yet its effects on watermelon alone or combined with branch pruning remain poorly documented. This study evaluated three CBM rates (0, 2.25, and 4 t ha?¹) combined with three pruning levels (no pruning, three branches, and five branches), plus an NPK control, on the growth, yield, and fruit quality of yellow watermelon (Citrullus lanatus). The research was conducted in Cicalengka, Bandung Regency, using a single-factor Randomized Complete Block Design (RCBD) consisting of 10 structured treatment combinations with three replications, yielding 30 experimental units. Data were subjected to analysis of variance followed by Duncan’s multiple range test (P<0.05). Treatments significantly affected flowering time (P<0.01), total soluble solids (P<0.01), and fruit diameter (P<0.05), but not plant length, leaf number, stem diameter, canopy diameter, harvest index, fruit weight per plant, rind thickness, or sensory acceptance. Flowering was earliest at 2.25 t ha?¹ CBM with three branches (28.00 days after planting) and latest at 0 t ha?¹ with five branches (40.33 days), a 12.33-day difference. Total soluble solids ranged from 4.33 °Brix (4 t ha?¹, unpruned) to 10.33 °Brix (2.25 t ha?¹, five branches). Fruit diameter was largest at 2.25 t ha?¹ without pruning (8.07 cm) and smallest at 4 t ha?¹ with three branches (5.67 cm). The most favorable treatment differed among parameters, and no single treatment was superior overall.

PENGARUH KONSENTRASI PUPUK ORGANIK CAIR (POC) KEONG MAS (Pomacea canaliculata) BERBASIS ASAM AMINO TERHADAP PERTUMBUHAN DAN HASIL TANAMAN PAKCOY (Brassica rapa L.)

Pakcoy (Brassica rapa L.) is a leafy vegetable whose growth and yield depend strongly on nutrient availability. Declining soil fertility and low organic matter can constrain nutrient availability and crop productivity, particularly in intensively cultivated horticultural land. Golden apple snail (Pomacea canaliculata) is locally abundant and contains protein and amino acids that can be processed into liquid organic fertilizer (LOF). This study aimed to evaluate the response of pakcoy to different concentrations of amino-acid-based golden apple snail LOF and to identify the concentration producing the best growth and yield under the experimental conditions. The experiment was conducted from March to May 2026 in Binaka Village, Gunungsitoli Idanoi District, using a non-factorial Randomized Complete Block Design with five treatments (0, 20, 40, 60, and 80 mL/L) and five replications, for 25 experimental units. Data were analyzed using analysis of variance (ANOVA), followed by Duncan’s Multiple Range Test (DMRT) at the 5% level when significant. The 80 mL/L treatment produced the highest values at 4 weeks after transplanting, namely plant height of 29.04 cm, 18.00 leaves plant?1, and fresh weight of 348.80 g plant?1. Relative to the control, these values represented increases of 44.05%, 100.00%, and 316.23%, respectively. The results indicate that 80 mL/L was the best concentration among the concentrations tested. However, the optimum concentration beyond 80 mL/L and the physiological and biochemical mechanisms underlying the response require further study.

PENGARUH PEMBERIAN BOKASHI DAN PUPUK HAYATI TERHADAP MUTU FISIOLOGIS DAN PATOLOGIS BENIH KEDELAI (Glycine max (L.) Merril)

Soybean is a strategic food commodity that requires improvements in productivity and seed quality. Crop management through the application of bokashi and biofertilizers has the potential to improve growing conditions, support plant growth, and enhance the physiological quality and pathological health of seeds. However, the effectiveness of combinations of bokashi, Biofresh, and Agrisoy in maintaining seed quality during storage remains unknown. This study aimed to determine the effects of bokashi and biofertilizers on the physiological and pathological quality of soybean seeds. The study was conducted at the Agrotechnology Laboratory, Plant Pest and Disease Science Unit, Faculty of Agriculture, Universitas Halu Oleo, Kendari, using a Completely Randomized Design (CRD) with one factor consisting of six treatment combinations: control (B0A0), soybean straw bokashi + Biofresh biofertilizer (B1A1), soybean straw bokashi + Biofresh + Agrisoy biofertilizers (B1A3), rice straw bokashi + Biofresh biofertilizer (B2A1), rice straw bokashi + Biofresh + Agrisoy biofertilizers (B2A3), and soybean straw + rice straw bokashi + Biofresh + Agrisoy biofertilizers (B3A3). The research activities included land preparation, bokashi application, biofertilizer application, planting, crop maintenance, and harvesting. The results showed that the combination of bokashi and biofertilizers improved the physiological and pathological quality of soybean seeds. The combination of soybean straw + rice straw bokashi with Biofresh + Agrisoy biofertilizers (B3A3) showed the most balanced overall performance in maintaining germination capacity at 94.67%, maximum growth potential at 98.67%, growth uniformity at 94.67%, vigor index at 89.33%, and the lowest seed contamination at 13.33%.
