Abstract

Eggplant (Solanum melongena L.) is an important horticultural crop with high economic value and is widely cultivated in various regions due to increasing demand. This study aimed to determine the effects of gibberellin (GA3) concentration and eggplant varieties on the growth and yield of eggplant (Solanum melongena L.). The research was conducted in Kolomayan Village, Wonodadi District, Blitar Regency, from February to May 2025. A Completely Randomized Design (CRD) with a factorial arrangement of two factors was used. The first factor was gibberellin concentration at 0 ppm, 100 ppm, 200 ppm, and 300 ppm. The second factor was the eggplant variety, including Hitavi, Mustang, Pulus, and Teho 555. Parameters observed included vegetative and generative growth traits. The results showed a significant interaction between 200 ppm GA3 concentration and the Hitavi variety on total harvested fruit weight. The 200 ppm GA3 treatment alone produced the best results across all observed parameters. The Teho 555 variety excelled in plant height and leaf number, while the Hitavi variety outperformed others in flower number, total fruit number per plant, total fruit weight per plant, and fruit set.

Abstract

White jasmine (Jasminum sambac (L.) Aiton) is an ornamental plant of high economic value that requires access to quality, uniform seeds. Propagation through stem cuttings often faces challenges in root formation and initial growth. This study aims to analyze the effects of Indole-3-Butyric Acid (IBA) concentration and soaking time on the initial growth of white jasmine cuttings. The study employed a factorial completely randomized design with two factors: IBA concentration (0, 50, 100, and 150 parts per million) and soaking time (30, 60, and 90 minutes). The parameters observed included shoot emergence time, shoot length, number of leaves, number of primary roots, and root fresh weight. Data were analyzed using analysis of variance at a 5% significance level. The results showed a significant interaction between concentration and soaking time for all parameters. The combination of 100 ppm IBA with a 60-minute soaking time resulted in the fastest shoot emergence (11.27 days), the longest shoot length at eight weeks after planting (11.27 cm), the highest number of leaves (12.60), the greatest number of primary roots (12.52), and the largest fresh root weight (1.06 g). Treatments without growth regulators showed the lowest values for most parameters. Thus, a concentration of 100 ppm with a 60-minute soaking time was the most effective combination for enhancing the initial growth of white jasmine cuttings. Applying this treatment has the potential to improve seedling quality and uniformity, supporting the development of white jasmine cultivation.

Abstract

Background: Dendrobium orchids have high economic value (in 2020 generated an export value of US$61.87 thousand), yet micropropagated seedlings commonly exhibit slow growth and high mortality during the acclimatization stage. This problem is largely associated with the use of unsuitable planting media and inadequate nutrient supply, which limit seedling adaptation and survival after tissue culture. This study aims to determine the best combination of planting media and foliar fertilizer types for the growth of Dendrobium orchid seedlings during the acclimatization stage. Methodology: The study was conducted in Penambangan Village, Semanding District, Tuban Regency, East Java Province from November 2024 to February 2025 using a Completely Randomized Design (CRD) with 9 treatment combinations and 4 replications. The first factor was the treatment of planting media types (M1: Black Moss, M2: Rice Husk Charcoal, M3: Cocopeat), and the second factor was the type of foliar fertilizer (P1: Gandasil D, P2: Gaviota 63, P3: Grow Quick LB). The observed research variables included the percentage of live seedlings, plant height, leaf area, seedling growth rate, number of shoots, and number of roots. Findings: The results showed that the use of cocopeat planting media resulted in the highest percentage of seedling survival at 88.33%. The combination of cocopeat planting media and Grow Quick LB leaf fertilizer produced the best relative growth rate (RGR) at 8-12 WAP of 41.22 mg/month.This research produces the best combination of planting media and foliar fertilizer for orchid seedlings at the acclimatization stage. Contribution: The findings contribute to a more systematic understanding of how substrate physical properties and foliar nutrient supply interact to influence survival and growth performance during orchid acclimatization, offering a scientifically grounded framework for improving ex vitro propagation efficiency
