Optimalisasi Kombinasi Biochar dan Pupuk Kotoran Ayam Terhadap Morfologis Bawang Putih (Allium sativum L.) di Tanah Alluvial

Sutikarini — 2025-10-09

Garlic (Allium sativum L.) plays a strategic role as a food and health ingredient for the Indonesian people, but the high gap between national production and domestic demand requires efforts to expand agriculture, particularly on potential alluvial land in West Kalimantan. This study aims to evaluate and determine the optimal combination dose of biochar and chicken manure fertiliser on garlic growth parameters and yield on alluvial soil. This study was conducted in South Pontianak District, Pontianak City. The research method was a Complete Randomised Design (CRD) Factorial. The first factor was the biochar dosage (5, 10 and 15 tonnes/ha) and the second factor was the chicken manure dosage (10, 20 and 30 tonnes/ha), resulting in 9 treatment combinations, namely b1p1, b1p2, b1p3, b2p1, b2p2, b2p3, b3p1, b3p2, and b3p3. The combination of biochar and chicken manure had a significant effect on the morphology (bulb diameter and plant height) of garlic in alluvial soil. Among the various variations, the b2p3 treatment (10 tonnes/ha of biochar and 30 tonnes/ha of chicken manure fertiliser) was identified as the most effective dose for optimising plant growth beyond the achievements of other dose combinations.

Pakcoy (Brassica rapa L.) plays a strategic role as a food and health ingredient for the Indonesian people, but the high gap between national production and domestic demand requires efforts to expand agriculture, particularly on potential alluvial land in West Kalimantan. This study aims to evaluate and determine the optimal combination dose of biochar and Arbuscular Mycorrhizal Fungi (AMF) on pakcoy growth parameters and yield on Podzolic Red-Yellow soil. This study was conducted in Jawa Tengah Village, Ambawang District, Kubu Raya Regency from May to July 2025. The research method was a Randomized Complete Block Design (RCBD) with a single factor of AMF dosage consisting of six levels: F0 (control), F1 (10 g/plant), F2 (15 g/plant), F3 (20 g/plant), F4 (25 g/plant), and F5 (30 g/plant). Each treatment was replicated four times with 3 sample plants per replication, resulting in 72 plants total (6×4×3=72). Parameters measured included plant height, number of stems, fresh weight, and root volume. Results showed that AMF application had a highly significant effect (p<0.01) on the number of stems, fresh weight, and root volume, but no significant effect on plant height. Treatment F4 (25 g/plant) yielded the best results for plant height (32.25 cm) and number of stems (13.25 stems), while F5 (30 g/plant) produced the highest fresh weight (164.50 g) and root volume (9.75 mL). These findings indicate that AMF at dosages of 25–30 g/plant can effectively enhance pakcoy productivity on acidic, nutrient-poor soils

Pengaruh Pemberian Ekstrak Daun Kelor (Moringa oleifera) Terhadap Pertumbuhan dan Hasil Tanaman Seledri (Apium graveolens L.) di Tanah Podsolik Merah Kuning

Agus Suyanto — 2025-10-09

Seledri (Apium graveolens L. subsp. chinensis) is a highly nutritious vegetable crop with significant economic value, yet its productivity remains constrained by marginal soil conditions, particularly on Podzolic Red-Yellow soils widespread in tropical Indonesia. These soils are characterized by high acidity (pH < 5.5), low cation exchange capacity, high exchangeable aluminum, and nutrient deficiency. Moringa leaf extract (Moringa oleifera) has emerged as a promising natural biostimulant containing phytohormones (cytokinins, auxins), vitamins, and minerals that enhance vegetative growth. This study evaluated the effect of moringa leaf extract on seledri growth and yield on Podzolic Red-Yellow soil. The research was conducted in Nanga Tepuai Village, Hulu Gurung District, Kapuas Hulu Regency, from April to July 2024, using a Randomized Complete Block Design with six dosage levels: M0 (control), M1 (35 mL/L), M2 (40 mL/L), M3 (45 mL/L), M4 (50 mL/L), and M5 (55 mL/L), each replicated four times. Results showed highly significant effects (p < 0.01) on leaf number, but non-significant effects on plant height, fresh weight, and root volume. Treatment M5 (55 mL/L) produced the highest leaf number (15.25 leaves), M4 (50 mL/L) the tallest plants (26.75 cm), while M2 (40 mL/L) yielded the highest fresh weight (98.75 g) and root volume (7.25 mL). These findings suggest moringa leaf extract at 40–55 mL/L effectively stimulates leaf development in seledri on acidic, nutrient-poor soils

Pengaruh Pupuk Kompos Jerami Padi Terhadap Pertumbuhan dan Hasil Tanaman Bawang Daun (Allium fistulosum L.) pada Tanah Podsolik Merah Kuning

Setiawan — 2025-10-09

Green onion (Allium fistulosum L.) is an economically important horticultural crop widely used as a flavoring ingredient in Indonesian cuisine and valued for its nutritional content, including vitamin C, provitamin A, and essential minerals. However, productivity remains low among farmers, primarily due to cultivation on marginal soils such as Podzolic Red-Yellow (PMK) soil, which is widespread across Indonesia, particularly in Kalimantan, Sumatra, and Sulawesi. PMK soils are characterized by high acidity (pH < 5.5), high exchangeable aluminum, low cation exchange capacity, and deficiency in macronutrients such as nitrogen, phosphorus, and potassium, severely limiting crop growth and nutrient uptake. Rice straw compost represents a promising organic amendment to address these constraints, as it contains essential nutrients, improves soil structure, enhances cation exchange capacity, and stimulates beneficial soil microbial activity. This study evaluated the effect of rice straw compost at varying doses on the growth and yield of green onion cultivated on PMK soil. The research was conducted in Bugang Village, Hulu Gurung District, Kapuas Hulu Regency, from May to July 2024, using a Completely Randomized Design with six treatments: J0 (control/no compost), J1 (40 g/polybag), J2 (45 g/polybag), J3 (50 g/polybag), J4 (55 g/polybag), and J5 (60 g/polybag), each replicated four times. Parameters measured included plant height, leaf number, tiller number, and fresh weight. Results showed highly significant effects (p < 0.01) on leaf number and tiller number, but non-significant effects on plant height and fresh weight. Treatment J4 produced the tallest plants (60.00 cm), while J5 yielded the highest leaf number (23.75 leaves) and tiller number (6.25 tillers), and J3 resulted in the highest fresh weight (40.25 g). These findings indicate that rice straw compost at 50–60 g/polybag effectively enhances vegetative growth of green onion on acidic, nutrient-poor PMK soils
