Abstract

Mustard greens are a vegetable that thrives in soil rich in organic matter and sufficient moisture. Fertilization is essential for mustard greens. Bamboo shoots are a vegetable that can be used as a raw material for organic fertilizer. Liquid organic fertilizer from bamboo shoots contains gibberellins and a high organic carbon content, which can stimulate plant growth. This study aimed to determine the effect of applying liquid organic fertilizer (POC) from bamboo shoots on the growth of mustard greens. This research was conducted at the green house of the Faculty of Agriculture, Sam Ratulangi University, Manado. The study lasted for two months, from September to October 2025. The design used in this study was a completely randomized design (RAL) consisting of five treatments and four replications, resulting in 20 experimental units. The treatments given included P0: (Control), P1: (100 ml POC + 1 L water), P2: (200 ml POC + 1 L water), P3: (300 ml POC + 1 L water), P4: (400 ml POC + 1 L water). The results obtained from the administration of bamboo shoot POC significantly affected the growth of green mustard greens from plant height, number of leaves, fresh weight, root weight. The right POC concentration was shown in the P1 treatment (100 ml POC + 1 L water) with a plant height of 31.7 cm, number of leaves 14.75 strands, fresh weight 60.25 grams, and root weight 5.75 grams. Keywords: bamboo shoot, growth, liquid organic fertilizer, mustard greens, yield

Abstract

Spinach is a type of leafy vegetable that has high nutritional value and is widely consumed by the community as a source of important nutrients for the body. In general, spinach is known for its protein, vitamins A and C, and B vitamins, and also contains mineral salts such as calcium (Ca), phosphorus (P), and iron (Fe). Batik spinach (Amaranthus tricolor L.) is a plant that belongs to the Amaranthaceae family and originates from North Amerika. PGPR (Plant Growth Promoting Rhizobacteria) are a group of beneficial bacteria that live in the root zone (rhizosphere) and play an important role in enhancing plant growth and productivity.This study aimed to determine the effect of PGPR application on the growth and yield of batik spinach (Amaranthus tricolor L.) and to find optimal concentration of PGPR. The study wa conducted in the greenhouse of the Faculty of Agriculture, Sam Ratulangi University, Manado, in June to July 2025, using a completely randomaized design (CRD) with 5 treatments and 4 replications (20 plants). The treatments were plant height, number o leaves, fresh weight, and root weight. The results showed that PGPR treatment affected the growth of batik spinach, with the optimal concentration being 35 ml/L of water. Keywords: batik spinach, growth, nutritional value, plant growth promoting rhizobacteria, yield

Abstract

This study aims to analyze the physical and chemical properties of compost produced from a mixture of dry leaves and vegetable waste through fermentation of Local Microorganisms (MOL) from goroho banana stems. The study was conducted in October–December 2025 with two main treatments, namely the addition of 30 ml, 60 ml, and 90 ml of MOL to a mixture of 1 kg of dry leaves and 2 kg of vegetable waste, the compost analyzed was a compost that had a faster composting time with a crumbly texture and a blackish brown color. The parameters observed included composting time, texture, color, and the content of macronutrients nitrogen (N), phosphorus (P), and potassium (K). The research data will be analyzed using descriptive statistics, the test results are presented in tabular form. The results showed that the 90 ml MOL treatment produced the fastest composting time, which was 25 days, while the 60 ml treatment required 30 days. Both treatments produced compost with a crumbly texture and a blackish brown color, indicating that the compost was mature. The nutrient content of the compost in the 60 ml MOL treatment was N 0.49%, P 0.06%, and K 0.54%, while in the 90 ml MOL treatment it was N 0.42%, P 0.03%, and K 0.55%. Keywords: compost, dry leaf, fermentation, vegetable, waste
