Abstract

Caisim (Brassica chinensis var. Parachinensis) is a type of vegetable that is in great demand by the public, because it contains many nutrients that humans need. Using chicken manure on caisim plants to provide nutrients for plant survival and growth. This research aims to see and determine the growth response of caisim plants (Brassica chinensis var. Parachinensis) by administering varying doses of chicken manure. This research was carried out in Sea Village, Pineleng District, Minahasa North Sulawesi from January to February 2023.This research used a completely randomized design (CRD) method with varying doses of chicken manure, with chicken manure needs are : Without treatment (A0), 312,5 grams/ polybag (A1), 625 grams/ polybag (A2), 937,5 grams/ polybag (A3). Data analysis from the observations was analyzed using Analysis of Variance (ANOVA) and continued with the Least Significant Difference Test (LSD) with unequal replications.From the research result, the caisim plant lacks light in the plant growth process. The hypothesis was also rejected because varying doses of chicken manure had no effect on the growth and development of the caisim plant. It is recommended to choose an ideal research location for succes in the cultivation process, the importance of the need for sunlight in plant growth to influence photomorphogenesis, namely plant growth and development which is directly controlled by sunlight. Keywords : caisim, dosages of chicken manure

Abstract

This study aims to determine the effect of combining Fruit-Based Local Microorganisms fertilizer with inorganic fertilizer on pakcoy yield, and to identify the most effective combination for enhancing production. The research was conducted from May to June 2025 in Kaskasen II Village, North Tomohon, North Sulawesi, using a Completely Randomized Design with one-factor combinations and six treatments (A: 150 ml/L water, B: 100 kg/ha NPK + 100 kg/ha Urea, C: 50 kg/ha NPK + 50 kg/ha Urea + 150 ml MOL, D: 50 kg/ha NPK + 50 kg/ha Urea + 300 ml MOL, E: 100 kg/ha NPK + 100 kg/ha Urea + 150 ml MOL, F: 100 kg/ha NPK + 100 kg/ha Urea + 300 ml MOL), each with four replications. The observed parameters included plant height, number of leaves, leaf length, leaf width, and fresh weight. The results showed that the combination of inorganic fertilizer and MOL had a significant effect on fresh weight (846.62 g), but no significant effect on plant height, number of leaves, leaf length, or leaf width. Therefore, the combination of inorganic fertilizer and MOL is effective in improving pakcoy yield. Keywords: pakcoy, inorganic fertilizer, local microorganisms

Abstract

ABSTRACT Pakcoy (Brassica rapa L.) is a horticultural crop that is highly favored by the public; however,its productivity has declined due to limited land availability. The wick hydroponic system is an efficient alternative cultivation method. This study aimed to determine the effects of different growing media and to identify the best medium for the growth and yield of pakchoi. The research was conducted from May to June 2025 in Kotamobagu, North Sulawesi (789.71 meters above sea level), using a Randomized Block Design (RBD) with four treatments of growing media (rockwool, cocopeat, rice husk charcoal, and compost) and four replications. The observed variables included plant height, number of leaves, leaf length, and fresh weight. The results showed that the growing media treatments had a significant effect on all parameters. Compost medium (P4) produced the best growth and yield response, with a plant height of 23.06 cm, 16.5 leaves, a leaf length of 11.25 cm, and a fresh weight of 53.88 g. In conclusion, compost is the most suitable growing medium for pakchoi cultivation in the wick hydroponic system. Keywords: Pakcoy, hydroponics, wick system, growing media, compost.

Abstract

Accurate and environmentally friendly fertilization is essential to optimize the growth of vegetable crops. This study aims to examine the effects of coconut water-based Liquid Organic Fertilizer (LOF) on the growth and yield of red amaranth (Amaranthus tricolor L.) under different application frequencies. The experiment was conducted from February to April 2025 at the Greenhouse of the Faculty of Agriculture, Sam Ratulangi University, Manado. A Completely Randomized Design (CRD) was used with four treatments: F0 (control/no LOF), F1 (LOF application once per week), F2 (twice per week), and F3 (three times per week), with each treatment receiving 250 ml per liter of water. Each treatment was replicated four times for a total of 16 experimental units and 32 plants. Observed parameters included plant height, number of leaves, and fresh weight. The results showed that application of coconut water LOF once a week (F1) significantly improved plant height, leaf number, and biomass compared to the control. However, increasing frequency beyond once a week (F2 and F3) did not lead to significant improvements, suggesting that one weekly application is sufficient and efficient. Therefore, coconut water-based LOF is recommended as an effective, eco-friendly alternative for red amaranth cultivation. Keywords: Red amaranth, Amaranthus tricolor L., liquid organic fertilizer, coconut water, frequency, plant growth

Abstract

Chrysanthemum is an ornamental plant prepared for export by the City of Tomohon, but the availability of seedlings remains limited. Vegetative propagation with the aid of garlic extract as a natural growth regulator (PGR) can be a solution to accelerate the rooting of shoot cuttings.This study aimed to determine the effect of using garlic extract (Allium sativum L.) and to identify the best concentration of garlic extract as a natural PGR on the root development of chrysanthemum shoot cuttings (Chrysanthemum morifolium R.). The research was conducted in September 2024 at the Screen House of the UPTD Seed Breeding and Agrotourism Show Window, Tomohon City. The study used a Completely Randomized Design (CRD) with five levels of garlic extract concentration treatments: P0 (0% garlic extract + 100% sterile water), P1 (25% garlic extract + 75% sterile water), P2 (50% garlic extract + 50% sterile water), P3 (75% garlic extract + 25% sterile water), P4 (100% garlic extract + 0% sterile water). Each treatment was replicated three times, with three cuttings per experimental unit, resulting in a total of 45 cuttings. The observation data were analyzed using ANOVA and further tested with the 5% Least Significant Difference (LSD) test. The results showed that garlic extract had an effect on the root length of chrysanthemum shoot cuttings and provided protection against pest and disease attacks. Keywords: Garlic extract; Natural PGR; Shoot cuttings; Root growth; Chrysanthemum.
