Abstract:Cayenne pepper (Capsicum frutescens L.) is a horticultural commodity with high economic value and continuously increasing market demand. The success of cayenne pepper production is largely determined by vegetative growth…
in the early stages, which is influenced by the availability of nutrients and plant growth regulators. The use of manure as a source of organic matter and natural Plant Growth Regulators (PGRs) is expected to enhance vegetative growth. This study aimed to determine the effect of manure application and natural PGRs on the vegetative growth of cayenne pepper and to identify the treatment that produces the best growth.The research was conducted from December to January 2026 at the land of the Kopbun Suka Tani Sejahtera Business Research Center, Kota Juang District, Bireuen Regency. The study used a factorial Randomized Block Design (RBD) with a 4 × 3 pattern and three replications. The first factor was the dosage of manure consisting of 0 kg (control), 1 kg, 1.5 kg, and 2 kg per plant. The second factor was the type of natural PGR, consisting of shallot extract, rice water, and coconut water. The observed parameters included plant height, number of leaves, leaf width, and number of branches at 15, 30, and 45 days after planting (DAP). Data were analyzed using the F-test and continued with the Honestly Significant Difference (HSD) test at a 5% significance level if the results were significant.The results showed that manure application had no significant effect on all vegetative growth parameters up to 45 DAP. The application of natural PGRs also showed no significant effect at 15, 30, and 45 DAP, as well as on other parameters. There was no significant interaction between manure and natural PGRs on all observed parameters.
Abstract:This study aims to determine the effect of manure dosage and types of plant growth regulators (PGRs), as well as their interaction, on the generative phase of bird’s eye chili plants (Capsicum frutescens L.) in order to…
o improve productivity, which remains fluctuating due to suboptimal cultivation practices. The research was conducted from February to March 2026 at the experimental field of the Pusat Riset Bisnis Kopbun Suka Tani Sejahtera, Kota Juang District, Bireuen Regency, using a factorial Randomized Block Design (RBD) of 4 × 3 with three replications. The first factor was the dosage of manure (control, 1 kg/plant, 1.5 kg/plant, and 2 kg/plant), while the second factor was the type of natural PGR (onion extract, rice water, and coconut water). Data were collected through direct observations on several parameters, including number of fruits, fruit weight, fresh biomass weight, root fresh weight, and root length, and were then analyzed to determine the effects of treatments and their interactions.
The results showed that certain doses of manure had a significant effect on increasing yield and root growth, while natural PGRs were able to enhance flowering, reduce flower drop, and accelerate fruit formation. The interaction between both treatments indicated that the optimal combination produced higher results compared to single treatments. The novelty of this study lies in the use of a combination of manure and natural PGRs based on local materials as a strategy to improve the generative phase. The implications of this research are expected to serve as a scientific reference for the development of sustainable cultivation techniques, as well as learning material and further research in the fields of agronomy and horticulture.
Abstract:This research was conducted at the UPT Benih Induk Palawija located in North Sumatra, precisely at Jl. Pendidikan No. 23, Tanjung Selamat, Sunggal District, Deli Serdang Regency, the research was conducted in the period…
of June--September 2023. RAK or Randomized Block Design through factorial with two treatment factors was used as the method of this research. Three levels namely: D1 = 0 g / plot (0 kg / ha), D2 = 40 g / plot (270 kg / ha), D3 = 60 g / plot (400 kg / ha), the three of them became the first factor of dolomite (D) dosage which was grouped into three levels. In addition, N1 = 30 g / plot (200 kg / ha), N2 = 45 g / plot (300 kg / ha), N3 = 60 g / plot (400 kg / ha), the three of them became the second factor of NPK Mutiara fertilizer dosage which was divided into three levels. Dolomite application, 60 g/plot produces optimal yield and growth of peanut plants, namely the weight of 100 dry seeds, plant height, pod weight per plot, flowering age, pod weight per plant, number of branches, number of filled pods per plant, number of gynophores per plant, number of empty pods per plant, and total number of pods per plant are significantly affected by dolomite application. Meanwhile, application of NPK Mutiara fertilizer with a dose of 60 g/plot shows the same thing. The combination of dolomite and NPK Mutiara fertilizer only has a significant effect on the number of gynophores per plant.
