Abstract

This study aims to evaluate the effect of soil tillage systems and NPK fertilizer doses on the growth and yield of sweet corn (Zea mays L.). The study was conducted using a two-factor factorial RAK, namely soil tillage (no tillage, minimum, and maximum) and NPK doses (0, 60, 90, and 120 g/plot). The results showed that the maximum soil preparation treatment (O3) and NPK fertilizer rate of 120 g/plot (P3) generally yielded the best results. However, the combination of O1P2 (no soil preparation + 90 g of fertilizer) also showed high yields on certain parameters, indicating the potential for fertilizer efficiency without the need for intensive soil preparation. This study underscores the importance of combining appropriate land management and fertilization practices to sustainably enhance sweet corn productivity. Keywords: sweet corn, soil tillage system, NPK fertilizer, growth, yield

Abstract

This study focuses on controlling Fusarium wilt disease in red chili plants, a common horticultural crop in Indonesia. The disease caused by Fusarium pathogens poses challenges to farmers. An alternative control method is the use of biofungicides derived from fungi Trichoderma harzianum and Trichoderma koningii. The research was conducted at two different locations, including the isolation of Fusarium pathogens and identification of  Trichoderma fungi. The multiplication of  T. harzianum and  T. koningii was carried out on a rice medium at the Agensia Hayati / Botanical Pesticide Laboratory in Biaung. Seedling planting and biofungicide application took place at the Agensia Hayati Laboratory field, Jalan Tegal Harum, Gang Sakura, Biaung, East Denpasar District, Denpasar City, Bali, from May to August 2025.The experimental design used was a Completely Randomized Design (CRD) with 7 treatments and 5 replications. Treatments included a control (0 grams) and biofungicide doses of 10, 20, and 30 grams for both T. harzianum and T. koningii. Statistical analysis using one-way ANOVA showed significant differences (p<0.05) among treatments in reducing Fusarium wilt disease intensity. The highest dose of 30 grams of both biofungicides was the most effective, achieving 100% disease suppression 28 days after treatment. Additionally, the biofungicide application showed significant effects on the number of leaves at 7 days after treatment and plant height at 28 days after treatment. These results indicate that biofungicides from T. harzianum and T. koningii can be used as an environmentally friendly and sustainable alternative to control Fusarium wilt in red chili plants. Keywords: Fusarium Wilt, red chili pepper, Trichoderma harzianum, Trichoderma koningii

Abstract

Tomato (Solanum lycopersicum L.) is one of the vegetable commodities cultivated by farmers in Indonesia and is considered a multifunctional crop. In addition to being consumed as a vegetable, tomatoes are also used as raw materials in the pharmaceutical and cosmetic industries, as well as in food processing. This research was conducted at the Research Field of Pembangunan Panca Budi University, located in Dusun 3, Sampe Cita Village, Kutalimbaru District, Deli Serdang Regency, North Sumatra, at an altitude of approximately 500 meters above sea level. The aim of the study was to determine the effect of cow manure and banana peel liquid organic fertilizer (POC) on the growth and yield of tomato plants. The experiment employed a factorial randomized block design (RBD) with two factors, namely cow manure (K) and banana peel liquid organic fertilizer (C), each replicated three times. Factor I consisted of cow manure application (K) at four levels: K0 = 0 kg/plot, K1 = 1.5 kg/plot, and K2 = 3 kg/plot. Factor II consisted of banana peel POC application (C) at four levels: C0 = 0 ml/L water/plot, C1 = 175 ml/L water/plot, C2 = 350 ml/L water/plot, and C3 = 525 ml/L water/plot. The results showed that the application of cow manure and the concentration of banana peel POC significantly influenced plant height, stem diameter, number of fruits per plot, fruit weight per sample, total fruit weight per plot, and fruit diameter. However, these treatments did not significantly affect flowering time.. Keywords: cow manure fertilizer, banana peel liquid organic fertilizer (POC), tomato

Abstract

Ipomoea reptans P. commonly known as water spinach, is a leafy vegetable with high economic value and is widely consumed by the Indonesian population. This plant is extensively cultivated due to its short harvest cycle of approximately 25–30 days after planting, which provides farmers with the opportunity to increase land productivity. This study was conducted on agricultural land at the Universitas Pembinaan Masyarakat Indonesia (UPMI), Medan, from June to August 2025. A factorial Randomized Block Design (RBD) 4×4 with three replications was employed. The first factor was the Auxin Plant Growth Regulator (PGR) with four levels: Z0 = control, Z1 = 50 ml/L, Z2 = 100 ml/L, and Z3 = 150 ml/L. The second factor was POC PSB with four levels: P0 = control, P1 = 50 ml/L, P2 = 100 ml/L, and P3 = 150 ml/L. The results indicated that the application of Auxin PGR significantly affected the production parameters, with treatment P2 (100 ml/L) yielding a fresh weight of 58.1 grams. Furthermore, the interaction between Auxin PGR and POC PSB had a highly significant effect on the fresh weight of plants. The optimal combination was found in treatment Z3P2 (150 ml/L Auxin + 100 ml/L POC PSB), resulting in a fresh weight of 65.7 grams. In conclusion, the combined application of 150 ml/L Auxin PGR and 100 ml/L POC PSB significantly enhances the growth and yield of Ipomoea reptans and represents an environmentally friendly alternative technology to improve horticultural productivity. Keywords: ipomoea reptans, auxin plant growth regulator, POC PSB, growth, yield

Abstract

Japanese cucumber (Cucumis sativus L.) is one of the popular horticultural commodities due to its high nutritional value and benefits for health and beauty. However, the continuous use of chemical fertilizers to increase production can lead to environmental degradation and a decline in soil quality. Therefore, sustainable and eco-friendly cultivation innovations are needed, such as the use of organic fertilizers like cattle manure bokashi and biofertilizers such as Arbuscular Mycorrhizal Fungi (AMF). This study aimed to determine the effect of cattle manure bokashi and AMF application on the growth and yield of Japanese cucumber plants. The research was conducted experimentally using a Randomized Complete Block Design (RCBD) with a combination of bokashi and AMF treatments. Observed parameters included stem diameter, number of fruits per sample, fruit weight, and fruit length. The results showed that the application of bokashi and AMF, both individually and in combination, had a highly significant effect on plant yield. The best combination treatment was able to optimally improve both the quality and quantity of Japanese cucumber production. Keywords : bokashi, CMA, japanese cucumber, organic fertilizer, growth, production

Abstract

This study aims to determine the effect of MKP fertilizer and ecoenzyme, as well as to determine the effect of interaction on the application of MKP fertilizer and ecoenzyme in improving the quality of growth, production, and secondary metabolite content tests. This study was conducted from December 2024 to March 2025 in Klumpang Village, Hamparan Perak District, North Sumatra. Using a factorial randomized block design (RAK) with 2 treatment factors, each treatment repeated 3 times. The parameters observed were plant height (cm), number of leaves (strands), fresh plant weight (gr), wet tuber weight (gr), dry tuber weight (gr) and secondary metabolite tests on 6 compounds, namely alkaloids, flavonoids, terpenoids, saponins, and tannins. The results showed that MKP fertilizer had a significant effect on plant height at 4 WAP, 6 WAP, 8 WAP, plant weight parameters, wet tuber weight, and dry tuber weight. The best treatment was M1 (MKP dose of 10 gr/plant). Ecoenzyme treatment did not significantly affect all parameters. The interaction between MKP fertilizer and ecoenzyme did not significantly affect all parameters. The best treatment combination was M2E0 (MKP 20 grams/plant and ecoenzyme (control)). The phytochemical test of secondary metabolites in shallot (Allium cepa L) extracts continued to increase with increasing doses of MKP and ecoenzyme fertilizers. The best treatment was M2E2 (MKP 20 grams/plant and ecoenzyme 20 ml/liter of water) with results of 4 to 5 plus as shown in the lab results. Keywords: MKP, ecoenzyme, red onion, secondary metabolite

Abstract

Eggplant (Solanum melongena L.) is a vegetable crop cultivated for its fruit, which is used as a food ingredient, either consumed fresh or processed into various dishes due to its pleasant taste. The decline in purple eggplant production can be caused by several factors, including poor soil fertility, inadequate cultivation practices, and improper fertilizer use. This study aims to analyze the effect of compost and NPK 16:16:16 fertilizer on the growth and yield of purple eggplant, as well as the interaction between the two types of fertilizers. The research was conducted at the experimental field of the Faculty of Agriculture, Universitas Pembinaan Masyarakat Indonesia, using a factorial randomized block design (RBD). The factors tested were compost doses (0, 1, 2, and 3 kg/plot) and NPK 16:16:16 doses (0, 50, 100, and 150 grams/plot). Eggplant growth data were measured at 14, 21, and 28 days after planting and analyzed using ANOVA followed by Duncan's multiple range test. The results showed that the best fertilizer treatment for eggplant growth was the combination of 3 kg compost/plot and 150 g NPK/plot, which resulted in a plant height of 70.3 cm. This indicates that the combination of both fertilizers significantly improved plant growth compared to other treatments. Keywords: eggplant, compos, NPK fertilizer

Abstract

This study aimed to examine the effect of Arbuscular Mycorrhizal Fungi (AMF) and cow manure fertilizer on the growth and yield of purple eggplant (Solanum melongena L.), as well as their interaction in enhancing productivity. The research was conducted using a factorial Randomized Block Design (RBD) with two factors. The first factor was AMF (M) with four levels: M0 = without AMF, M1 = 10 g/plot (100 kg/ha), M2 = 15 g/plot (150 kg/ha), and M3 = 20 g/plot (200 kg/ha). The second factor was cow manure fertilizer (P) with four levels: P0 = without cow manure, P1 = 1 kg/plot (10 tons/ha), P2 = 2 kg/plot (20 tons/ha), and P3 = 3 kg/plot (30 tons/ha). The observed parameters included plant height, number of leaves, number of branches, fruit diameter, fruit length, number of fruits per plot, and fruit weight per plot. The results showed that AMF significantly affected all growth and yield parameters. Cow manure fertilizer significantly influenced most parameters, especially fruit diameter, fruit length, number of fruits, and fruit weight. The interaction between AMF and cow manure fertilizer had a significant effect on yield parameters but was not significant for all vegetative growth parameters. Overall, the combination of 15–20 g/plot AMF with 2–3 kg/plot cow manure produced optimal growth and yield of purple eggplant..
