Abstract

Green spinach is one type of vegetable commodity that the people of Indonesia most widely consume because it has a relatively high nutritional content such as iron, vitamin C, protein, and carbohydrates. However, currently, there is a decrease in green spinach vegetable productivity in Indonesia due to several things, including cultivation techniques that could be more optimal, low seed quality, and limited application of agricultural technology. For this reason, agrarian intensification is needed by using natural plant growth regulators (PGR) to increase the growth of green spinach. Red onions and shallots are part of the allium genus, which has growth phytohormones, namely auxin and gibberellins, which have the potential to be natural PGR. This study aims to compare the use of red onion and shallot extracts in increasing the growth of green spinach plants. The research design used was a randomised group design (RGD) with variations in extract concentrations (0%, 15%, 30%, 45%). Parameters of observation of green spinach plant growth are plant height, number of leaves, leaf circumference, and wet biomass of harvested plants. The application of red onion and shallot extracts was carried out on green spinach plants aged seven days after planting (DAP) with a time interval of 1 week until 28 DAP. Observation of green spinach plant growth parameters began at the age of 14-35 DAP. Statistical analysis of the data using analysis of variance (ANOVA) and then the Duncan Multiple Range Test (DMRT) further t-test a 5% significance level. The results showed that red onion and shallot extracts affected all observed growth parameters of green spinach plants. Shallot extract with a concentration of 45% gave the best results on all green spinach plant growth parameters.

Abstract

Indonesia has abundant horticultural commodities, including chilli plants, which have high economic value. However, their productivity remains low at 8.35 tons/ha, compared to the potential 20–40 tons/ha. To boost the productivity of red cayenne pepper, additional supplements such as phytohormones auxin, gibberellin, and cytokinin are needed. This study uses natural sources of phytohormones derived from banana stems and mung bean sprouts. The aim is to measure the antioxidant activity and total phenolic content of various combinations of these natural plant growth regulators (PGRs) to support plant productivity. An experimental design was used, analyzing antioxidant activity using the DPPH method with IC50 values, and total phenolics using the Folin-Ciocalteu method. Six variations were tested: A (banana stem extract 10:0), B (banana stem:bean sprouts 8:2), C (6:4), D (4:6), E (2:8), and F (bean sprout extract 10:0). Antioxidant activity and total phenolics were measured using a UV-Vis spectrophotometer. The results showed that variation C (6:4) had the highest total phenolic content (8.8 mg GAE/g) and an IC50 value of 210 ppm, indicating moderate antioxidant activity. These findings suggest that the combination of banana stem and bean sprout extracts in the right proportion can enhance the functional properties of natural PGRs, potentially supporting the growth and productivity of red cayenne pepper plants.

Abstract

Organic farming is now increasingly gaining attention as a solution to the challenges of environmental damage and the need for healthy food in the modern era. One important aspect of organic farming practices is the use of natural Plant Growth Regulators (PGRs) to increase crop yields and quality. This study aims to examine the potential combination of red onion and bean sprout extracts as natural PGRs through total phenolic analysis and antioxidant activity as a reference basis for further application to potato plants. Extracts from both materials were obtained through the maceration method, then formulated in six different ratio comparisons and analyzed for their total phenolic content using the Folin–Ciocalteu method and their antioxidant activity through the DPPH test. The results showed that variation B (8 g/L red onion + 2 g/L bean sprouts) had the highest total phenolic content of 14.77 mg GAE/g and the strongest antioxidant activity with an IC50 value of 173.7 ppm. The results were supported by the DMRT test, which showed significant differences between the combination variations. The content of natural hormones such as auxin, gibberellin, and cytokinin in both materials works synergistically in stimulating the biosynthesis of secondary metabolites such as phenolics, which contribute to antioxidant activity and its effectiveness as a PGR. Thus, variation B has the highest potential to be developed as an environmentally friendly and sustainable natural PGR to support the growth and resistance of potato plants. This formulation shows promising potential for further development in the field of organic farming and nature-based agricultural innovation.

Abstract

The demand for soybeans continues to increase, but local production remains insufficient, requiring strategies to enhance productivity and quality, such as the application of Plant Growth Regulators (PGRs). Natural PGRs derived from moringa leaves and mung bean sprouts, which are rich in auxins and cytokinins, have the potential to accelerate growth and stimulate the production of secondary metabolites. This study investigated various proportions of moringa leaf and mung bean sprout extracts to evaluate their phenolic content, antioxidant activity, and potential as natural PGRs in soybean cultivation. The extracts were analyzed using the Folin–Ciocalteu method for total phenolics and the DPPH assay for antioxidant activity. Among the treatments, Variation E, with a higher proportion of mung bean sprout extract, proved to be the most effective, enhancing both antioxidant activity and phenolic compound production. These findings highlight the novelty of combining moringa leaf and mung bean sprout extracts as a natural PGR strategy, demonstrating promising potential to support soybean growth and improve crop quality.

Abstract

Mustard plants are green plants that can be cultivated easily in various climatic conditions and can be consumed as a companion to cooking. In addition, mustard plants have enough content to meet the human body's needs. Giving a combination of PGR concentration of red onion extract and the right combination of media composition can affect mustard plants' growth and propagation system. This study aims to determine the effect of PGR red onion extract and the best composition of planting media, as well as to know whether there is an interaction between PGR and the composition of planting media regarding the growth and production of mustard plants. Sample selection is carried out using random sampling techniques in each population. The study was conducted in July-August 2023 in the Pasuruan City area using the 2-factor RAK (Group Random Design) research method. The first factor is the concentration of PGR, which consists of control (T0), concentration of 10% (T1), concentration of 20% (T2), and concentration of 30% (T3). The second factor is the composition of the planting medium with a ratio of soil, husk charcoal, and manure, namely (1: 2: 1) and (1: 1: 2). The results showed that the PGR factor of red onion extract with a concentration of 30% had a very real influence and gave the best results on the parameters of plant height, leaf width, and wet biomass of mustard plants. Planting media factors significantly affect and provide the best results in 1: 1: 2 treatment regarding plant height parameters at age 35-42 HST and wet biomass of mustard plants. The interaction between PGR and planting media has a real effect on the wet biomass of plants but does not have a real effect on plant height and leaf width of mustard plants.

Abstract

The euphorbia flower (euphorbia geroldii), widely used by the public as an ornamental plant because of its visual beauty, has an aesthetic function and health benefits that still need to be researched. The euphorbia genus has antimicrobial, antioxidant, and antidiabetic activity, which comes from its abundant terpenoid compounds, flavonoids, and other phytochemical compounds. Due to these high benefits, optimization of cultivation is carried out by adding phytohormones, better known as Growth Regulatory Regulator (PGR), further to increase the quality and quantity of euphorbia flowers so that the economic value will also increase in the realm of the agricultural industry. This research aims to analyze the effect of the natural PGR concentration of red onions (Allium cepa L.) on the growth of euphorbia flowers, including the parameters of the number of flowers on one tree, the time the buds appear, and the duration of flower survival. The research method used was quantitative experimental using a one-factor Randomized Block Design (RBD), namely testing the effect of several variations in PGR concentration (0%, 1%, 3%, 5%, 7%, and 10%) and statistically analyzed using SPSS. The results of the research show that all variations in PGR concentration have a positive effect on all parameters, where the PGR concentration of 10% indicates the highest increase, including the average number of flowers on one tree, which is 13 flowers, the average time for buds to appear is 2.5 times in one week. The average duration of flower survival is 139.5 hours. It can be concluded that the natural PGR of red onions has a positive effect on all parameters, with the highest results shown at a concentration variation of 10%.
