Abstract

Red garlic (Allium ascalonicum L.) is one of the most important holticultural commodities for society, both in terms of its high economic value and its nutrient content. One attempt to boost the growth of onion crops through cultivation techniques is fertilization aimed at increasing soil productivity by supplying plant nutrients. One of the fertilizers used is cattle barracks and NPK fertilizer in the polybag. In increasing the production of red onions need the addition of the element of hares that are ephesien. This study used a factorial random group plan (RAK) consisting of two factors, namely the first factor of cattle cage fertilization as basic fertilizer (K) consists of three dimensions: K0 = 0 g/polibag, K1 = 100 g / polibag and K2 = 200 g / polyibag. The observed parameters are the height of the plant (cm), the number of leaves (leaves), the amount of bulbs per plant, the weight of the bulb per plot. Analysis with ANOVA, continued with DMRT at 5% if there is a real treatment. Average height of red garlic crop gives the highest results on treatment K1 = 100 g/ polibag and P1 = 3 g/polibag is 25.79 (cm). The best treatment on the number of leaves parameter is K0 = 0 g/Polibag, and the best treatment of P1 is 3 g /polibags of 11.44 leaves. Best treatment on parameter number of bulbs per plant is K1= 100 g / polibags and P2 = 5 g / polyibag of 7.17 bulbs. Keywords: red onions, cattle's cage fertilizer, NPK fertiliser

Abstract

Water spinach (Ipomea reptans Poir) is a type of vegetable that is very popular among Indonesians because of its delicious taste. This plant originated in India but then spread to various countries in Asia and Africa (Plucknett and Beemer, 1981). NPK fertilizer in water spinach cultivation is the most widely used compound fertilizer containing the nutrients Nitrogen, Phosphorus and Potassium. Organic fertilizers are fertilizers composed of living matter, such as weathering of plant, animal and human remains. This research will be carried out in the experimental field of the Faculty of Agriculture, Indonesian Community Development University UPMI Medan, on Jl. Waqf, Pasar 12 Marindal II, Patumbak District, Deli Serdang Regency, North Sumatra Province. Altitude 40 m above sea level. Based on the results of field observations, it directly shows the normal growth of land kangkong plants (Ipomoea reptans Poir.). Parameters observed included plant height (cm), number of leaves (strands), sample wet weight (g), overall wet weight (g), root length (cm) and root volume (mm). Single effect NPK fertilizer application at N2 level (1.5 gram/plant (300 kg/ha) has an effect on increasing plant height growth at 3 WAP) based on the 5% DMRT test. The interaction effect of NPK fertilizer and liquid organic fertilizer had no effect on plant height, number of leaves, sample wet weight, overall wet weight, root length and root volume.

Abstract

Strawberries are a plant that has various benefits. The fresh fruit and attractive color make strawberries very popular with all groups (Oktarina et al., 2017). In conventionally grown strawberry plants, flowers and stolons generally appear around 8 weeks after planting (WAP), and one parent plant is only able to produce 3 to 4 stolons. This research was carried out in Sempajaya Village, Berastagi District, Karo Regency, North Sumatra, at an altitude of 1,000–1,300 meters above sea level. This research was started in June–August 2023. The research method used was a randomized group design (RAK) with two factors, including: Factor I: Giving Nasa Liquid Organic Fertilizer (P), which consists of 3 levels: P0: control, P1: 2.5 ml, P2: 5 ml, and P3: 7.5 ml. Factor II: Stolon pruning (S) consists of 3 levels, namely: S0: no pruning; S1: 1 pruned stolon; and S2: 2 pruned stolons. From the results of this research, it can be concluded that the single effect of giving Nasa liquid organic fertilizer is significantly different on the number of fruit in harvest 1 and harvest 3, but is not significantly different on the number of fruit in harvest 2, plant height (cm), number of leaves (strands), and fresh weight of sample plants; the single effect of stolon pruning was not significantly different on plant height (cm), number of leaves (strands), number of fruit, and fresh weight of sample plants; and The interaction effect of giving Nasa liquid organic fertilizer and pruning stolons was not significantly different on plant height (cm), number of leaves (strands), number of fruits, and fresh weight of sample plants (g).

Abstract

Cayenne pepper or small chili (Capsicum frutescens L.) is an important horticultural crop in Indonesia which is most widely consumed by the community so that chili production has a very high potential and economic value for farmers also affects high economic value and is useful as a flavoring dish. This cayenne pepper plant is easy to grow in the lowlands and highlands and contains nutrients needed by the human body. Chili is a vegetable commodity that is not wasteful of land because it is more concerned with its cultivation technology to be improved so that production increases. Intensive cultivation and care of chili peppers and further using post-harvest technology creates new jobs. Some of the vitamin content contained in chili peppers includes vitamin C antioxidants that can prevent several diseases such as cancer and vitamin B which can improve digestion, help increase immunity and avoid the body from bacterial disease. One way to increase the yield of cayenne pepper plants is to increase soil productivity, using the addition of NPK fertilizer. This study used a factorial randomized group design (RAK). For accuracy in this study, it was repeated 3 times. namely: NPK fertilizer (N) with 3 levels, namely: N0 = Control, N1 = 15 g/plant, and N2 = 20 g/plant. From the ANOVA test results, the variance of treatments that have a significant effect is continued with the Duncan DMRT test at the 5% level. The results of the ANOVA test showed that the effect of NPK fertilizer treatment on plant height 2 weeks and 3 weeks, stem diameter (mm) 1 week, 2 weeks, and 3 weeks, and the number of flowers showed a significant effect. While the observation of plant height at 1 st, number of flowers, number of fruits per sample plant (g), and weight of fruits per sample plant showed no significant effect. The best average NPK fertilizer treatment is the treatment level N2 = 20 g/plant. Keywords: NPK fertilizer, NPK dosage, and cayenne pepper plants

Abstract

North Sumatra is shallots. Shallot (Allium ascolonicum L.) is a horticulture that has many benefits for people's lives, both from economic value and nutritional content, so that shallot production increases every year and is proven based on BPS (Central Statistics Agency) for the last 5 years. The effort needed to meet the needs of shallot production is to increase soil productivity, using the addition of NPK fertilizer. This study used factorial randomized group design (RAK). For accuracy in this study, it was repeated 3 times. namely: NPK fertilizer (N) with 3 levels, namely: N0 = Control, N1 = 5 g/plant, and N2 = 10 g/plant. The results of the Anova Variance test showed that the response of NPK fertilizer treatment to plant height 3 mst, 4 mst, 5 mst, 6 mst and wet weight of tubers per plot (g) had a significant effect, but the observation of the number of tubers per sample plant (tubers), and the diameter of tubers per sample (mm) had no significant effect.  Keywords: NPK fertilizer, NPK dosage, and shallots

Abstract

Yellow leaf curl virus infection in chili pepper (Capsicum frutescens L.) can significantly reduce crop yield. This study aimed to evaluate the effect of turmeric extract and NPK fertilizer doses on the incidence of yellow leaf curl virus in chili pepper plants. The research was conducted at the experimental field of Universitas Pembinaan Masyarakat Indonesia from June to August 2025 using a factorial Randomized Complete Block Design (RCBD) with two factors: turmeric extract (0%, 10%, 15%, 20%) and NPK dosage (0, 3.3 g, 5 g, 6.6 g per plant), resulting in 16 treatment combinations. Disease incidence was observed from 2 to 9 weeks after transplanting. The results showed that the highest incidence occurred at weeks 3 and 8. The K3P0 treatment (high-dose turmeric without NPK) resulted in the lowest incidence rate at 11.2%, while K1P3 (low-dose turmeric + high NPK) showed the highest at 137.5%. Although ANOVA results revealed no statistically significant differences (p>0.05), descriptively, high-dose turmeric treatments reduced symptoms and spread of disease. These findings highlight turmeric's potential as an eco-friendly botanical agent for managing viral diseases in chili cultivation. Keywords: chili pepper, disease incidence, NPK, turmeric, yellow leaf curl virus

Abstract

This study aims to determine the effect of dolomite and SP-36 fertilizer on the growth and production of red chili plants (Capsicum annum L.). The hypothesis tested in this study is the existence of a single response to dolomite and SP-36, as well as the interaction of both on the growth and production of red chili. The study was conducted from May to July 2024 at the experimental garden of the Faculty of Agriculture, Indonesian Community Development University (UPMI) Medan, using a factorial Randomized Block Design (RAK) with two factors: (1) Dolomite with three levels (D0 = without dolomite, D1 = 5 g/plot, D2 = 10 g/plot) and (2) SP-36 with three levels (S0 = without SP-36, S1 = 4.03 g/plot, S2 = 6.03 g/plot), with 9 treatment combinations. The results showed that dolomite administration had a very significant effect on the number of branches, fruit weight of sample plants, and fruit weight per plot, but was not significant on plant height and number of leaves at all observation ages. The treatment of dolomite 10 g/plot (D2) gave the best results for most parameters compared to the control (D0) and a dose of 5 g/plot (D1). The application of SP-36 fertilizer also had a very significant effect on the weight of the sample plant fruit and the weight of fruit per plot, but was not significant on plant height, number of leaves, and number of branches. The treatment of SP-36 at a dose of 6.03 g/plot (S2) showed the best results on several growth and production parameters. The interaction between dolomite and SP-36 had a very significant effect on the number of branches and weight of fruit per plot, but was not significant on other vegetative parameters. This study shows that the application of dolomite and SP-36 fertilizers significantly increases the production of red chili plants, especially in terms of the number of branches and fruit weight, with optimal doses of dolomite 10 g/plot and SP-36 6.03 g/plot. Keywords: dolomite fertilizer, SP-36, red chili
