Abstract

Eggplant is widely appreciated as a food source across all levels of society and is among the most popular dishes in various communities. Therefore, the growth and production of eggplant require fertilizers to supply essential nutrients. Fertilizer materials can utilize potential waste, such as market waste. To increase the phosphorus content in liquid organic fertilizer, it can be enriched with maja fruit. Liquid organic fertilizer derived from market waste, consisting of vegetables and fruits, contains high levels of nitrogen, which is a fundamental component of protein and chlorophyll in plants. The purpose of this study was to determine the effect of applying liquid organic fertilizer (POC) made from market waste enriched with maja fruit on the growth and production of purple eggplant (Solanum melongena L.). The experimental research employed a Non-Factorial Completely Randomized Design (CRD). The treatments were as follows: A0 – no POC application; A1 – POC concentration of 100 ml per liter of water; A2 – POC concentration of 200 ml per liter of water; and A3 – POC concentration of 300 ml per liter of water. The results showed significant effects on flowering and harvest age. The treatment that produced the best results across all parameters was A2, which involved applying market waste POC enriched with maja fruit at a concentration of 200 ml per liter of water. However, this treatment did not significantly affect plant height (cm), fruit weight per plant (grams), or the number of fruits per plant. The liquid organic fertilizer produced contains high levels of essential nutrients, such as boron (B) and iron (Fe), which accelerate the generative phase, including flowering, thereby advancing the plant's harvest age. Reason: The text was revised to improve clarity, coherence, and technical accuracy. Grammar, punctuation, and spelling errors were corrected. Vocabulary was enhanced for better readability and precision, and sentence structure was refined to ensure a smooth flow and a professional tone appropriate for scientific writing.

Abstract

Corn is a strategic food commodity with increasing demand, necessitating enhanced production through optimized fertilization, especially in marginal lands such as tidal areas. This study aims to evaluate the effect of foliar fertilizer application on three corn genotypes and its impact on nitrogen fertilizer use efficiency in tidal lands. A split-plot design with three factors was employed: the first factor was corn genotype; the second factor was urea fertilizer dose (0 kg, 255 kg, and 310 kg per hectare); and the third factor was foliar fertilizer treatment, which included no spraying (control), spraying on the 30th day, the 45th day, both the 30th and 45th days, the 60th day, the 75th day, and both the 60th and 75th days. Each treatment was replicated three times. The results indicated that applying 300 kg of urea fertilizer per hectare, combined with foliar fertilizer, positively influenced the growth of the G3 corn genotype and resulted in a high yield in tidal lands. This treatment produced 7.44 tons of corn per hectare, a significant increase compared to other treatments, making it an efficient strategy for enhancing corn productivity in tidal areas. It is recommended that farmers in tidal regions use a combination of 300 kg urea per hectare and foliar fertilizer applications to optimize corn yields.

Abstract

Pakcoy (Brassica rapa L.) is a short-lived leafy vegetable with high nutrient requirements and is highly responsive to environmental conditions, making it well-suited for cultivation using hydroponic systems. Additionally, the limited availability of agricultural land in urban areas due to land conversion necessitates efficient cultivation methods that do not rely on soil. Hydroponic systems offer more precise control over nutrient management and the growing environment compared to conventional soil-based cultivation, potentially increasing production efficiency on limited land. The success of hydroponic pakcoy production is significantly influenced by the type of growing medium, which supports root development, maintains water availability, and facilitates aeration and nutrient absorption. Therefore, research on various growing media is essential to identify the most effective medium for enhancing pakcoy plant growth and yield. This study aims to: 1) determine the effect of various growing media on the growth and production of pakcoy plants in hydroponic systems (Brassica rapa L.); and 2) identify the best alternative growing medium for optimizing the growth and production of pakcoy in hydroponic cultivation. The research was conducted from May to July 2025 in the greenhouse of the Payakumbuh State Agricultural Polytechnic, Harau District, Lima Puluh Kota Regency, West Sumatra. This study employed a completely randomized design (CRD) with a non-factorial approach. The factor studied was the growing media, consisting of seven treatments: rockwool, bamboo humus, coconut fiber, chopped fern, rockwool + bamboo humus, rockwool + coconut fiber, and rockwool + chopped fern. The parameters observed included plant height, number of leaves, leaf width, leaf length, root length, and fresh plant weight. The results indicated that variations in growing media significantly affected the growth and production of Pakcoy plants in the hydroponic system. The combination of rockwool and coconut fiber as planting media yielded the best results for Pakcoy plant growth and production. Therefore, the optimal alternative planting media for Pakcoy growth and production in the hydroponic system was rockwool combined with coconut fiber.

Abstract

Dry land has significant potential for cultivating hybrid corn. However, its limitations include water scarcity, poor soil physical properties, and limited availability of NPK nutrients. To improve dryland conditions, organic fertilizers, inorganic fertilizers, and organic fertilizers enriched with phosphate-solubilizing bacteria can be applied. The use of organic fertilizers—such as chicken manure and empty oil palm bunches (tankos)—as well as organic fertilizers enriched with phosphate-solubilizing bacteria, can enhance soil quality by improving its physical structure (making the soil looser and more fertile) and chemically increasing nutrient availability, thereby supporting better growth and yield of hybrid corn plants. This study aimed to evaluate the effectiveness of various fertilizer types on the growth and productivity of hybrid corn cultivated on dry land. The field experiment was arranged in a randomized complete block design (RCBD) with four treatments, each replicated six times: recommended chemical fertilizers (A), chicken manure fertilizer (B), organic fertilizer enriched with phosphate-solubilizing bacteria (C), and empty oil palm bunches (tankos) fertilizer (D). The highest yield was achieved using the recommended chemical fertilizer, producing 3.42 kg per plot (13.68 tons per hectare). The second highest yield was obtained with organic fertilizer enriched with phosphate-solubilizing bacteria, yielding 2.98 kg per plot (11.92 tons per hectare). The third-highest yield came from chicken manure fertilizer, producing 2.67 kg per plot (10.68 tons per hectare), followed by tankos fertilizer at 2.2 kg per plot (8.8 tons per hectare). The novel finding of this study is that organic fertilizer enriched with phosphate-solubilizing bacteria, without the addition of inorganic fertilizers, can achieve yields comparable to those obtained with recommended chemical fertilizers. While inorganic fertilizers are effective in increasing hybrid corn yields in the short term, their long-term use may negatively impact the environment and soil fertility. Therefore, organic fertilizer enriched with Azospirillum bacteria presents a more environmentally friendly and sustainable alternative.

Abstract

Kale (Brassica oleracea var. Acephala) is a plant that has good adaptability to various environmental conditions, and can be cultivated throughout the year with relatively simple cultivation. This study investigated the effects of LED light exposure duration (9, 12, and 15 hours/day) and various growing media (cocopeat, rice husk charcoal, and rockwool) on the growth of kale microgreens (Brassica oleracea var. Acephala) in a controlled indoor environment. Using a split-plot design, key parameters including plant height, leaf number, leaf greenness index, and fresh weight were evaluated over 14 days after planting (DAP). Results indicated that cocopeat significantly enhanced plant height (up to 10.76 cm) and fresh weight (0.55 g), while rockwool promoted superior leaf greenness (22.10 units) and leaf count (2.22 leaves). Longer light exposure (15 hours) improved leaf number, greenness, and fresh weight, with significant interactions observed in leaf count. These findings highlight optimal conditions for urban farming, supporting efficient nutrient-rich microgreen production amid declining agricultural land.

Abstract

Cucumber (Cucumis sativus L.) is a plant that has various advantages, one of which is a relatively short harvest period. This study was conducted to determine the most effective dose of NPK Phonska fertilizer and the optimal concentration of gibberellin growth regulator (GA3) to increase the growth and productivity of cucumber (Cucumis sativus L.) plants. This study was conducted from May to August 2025 at the Puri Serang Hijau, Serang City, Banten. The experiment was designed as a randomized block design with two treatment factors: the dose of NPK Phonska fertilizer (0, 350, 400, and 450 kg/ha) and the concentration of GA3 (0, 150, 175, and 200 ppm). The results showed that a single application of NPK Phonska fertilizer at a dose of 400 kg/ha gave the best effect on the growth and productivity of cucumber. This was reflected in greater plant height and more leaves, compared to other doses. The application of a single GA3 at a concentration of 200 ppm improved plant reproductive characteristics, such as accelerated flowering time. This study highlights the age of flower emergence and harvest age according to the varieties used as research objects.

Abstract

Sweet corn is a horticultural crop with high economic value and steadily increasing market demand. However, sweet corn productivity in Indonesia remains relatively low, ranging from 8 to 10 tons per hectare, well below its genetic potential of 12 to 15 tons per hectare. This low productivity is attributed to several factors, including soil fertility degradation caused by unsustainable cultivation practices, pest and disease infestations, and limited farmer access to quality agricultural inputs at affordable prices. Sweet corn plants respond well to inorganic fertilizers; however, long-term use of these fertilizers can degrade soil quality and fertility, reduce microbial activity, and increase production costs. Moreover, excessive reliance on inorganic fertilizers leads to soil nutrient imbalances, reduced organic matter content, and adverse environmental impacts. Therefore, efforts are needed to reduce this dependence, one of which involves utilizing eco-enzymes as an organic nutrient supplement. This study aimed to evaluate the growth and yield responses of Hybrid-F1 sweet corn plants to reduced NPK fertilizer doses, combined with eco-enzyme application via soil drenching and foliar spray. The study employed a Randomized Block Design with four replications and four treatment levels, comparing full NPK fertilizer doses, a 50% reduction in NPK fertilizer combined with eco-enzyme, and standalone eco-enzyme application. The results demonstrated significant improvements in fertilization efficiency, with the combination of a 50% reduction in NPK fertilizer and weekly applications of 1 ml/l eco-enzyme via soil drenching and foliar spray achieving optimal growth and production equivalent to full fertilization. Another important finding is that eco-enzyme can be used independently without inorganic fertilizers; plants still grew normally and produced ears, although yields were relatively lower. For best results, it is recommended to use a combination of a 50% reduction in NPK fertilizer dose and eco-enzyme application through both soil drenching and foliar spray. This approach not only reduces production costs by up to 50% but also promotes more sustainable and environmentally friendly cultivation practices.

Abstract

Shallot propagation using seeds or True Shallot Seed (TSS) faces several challenges, including low seedling survivalrates and slow seedling development. This study aims to evaluate the effects of silica concentration and plantingmethods on optimizing the growth and productivity of TSS shallot bulbs. The research was conducted at the UPTDevelopment of Rice and Secondary Crops Seeds in Malang Regency from February to June 2025. The experimentemployed a factorial design arranged as a Completely Randomized Design (CRD) with two factors, resulting ineight treatment combinations, each replicated five times. The first factor was silica concentration at four levels:0 g/L, 12 g/L, 14 g/L, and 16 g/L. The second factor was the planting method, with two levels: direct plantingand soil-block seeding. Observed parameters included seedling growth percentage, plant height, number ofleaves, number of bulbs, wet weight of stover per clump, dry weight of stover per clump, and dry weight of bulbs.The results indicated no significant interaction between silica concentration and planting method on the growthand yield of TSS shallot bulbs. However, the single treatment at 16 g/L silica concentration (S3) significantlyimproved seedling growth percentage and plant height, whereas the direct planting method (T1) yielded higherplant height. These findings suggest that applying a 16 g/L silica concentration and direct planting can enhanceshallot plant growth when propagated from TSS seeds.

Abstract

Growth and production of tomato (Lycopersicon esculentum) are influenced by the quality of the planting mediumand nutrient availability. This study aimed to determine the effects of planting medium and eco-enzymeconcentration on the growth and yield of tomato plants. A two-factor Randomized Block Design was used, withfactors including planting medium (soil; soil and rice husk charcoal 1:1; soil and cow manure 1:1; soil, rice huskcharcoal, and cow manure 1:1:1) and eco-enzyme concentration (0, 1, 2, and 3 ml/L). The results showed asignificant interaction between planting medium and eco-enzyme concentration on plant height from 28 to 63days after planting, number of fruits per plant, and fruit weight per plant. The best treatment was thecombination of soil and cow manure (1:1) with 3 ml/L eco-enzyme. The planting medium significantly affectedplant height at 14 to 21 days after planting, the number of leaves from 14 to 42 days after planting, and floweringage, while the eco-enzyme concentration significantly affected plant height at 14 to 21 days and the number ofleaves from 14 to 35 days after planting. The combination of organic growing media with eco-enzymes canenhance tomato growth and yield, particularly in terms of plant height, fruit number, and fruit weight per plant.These results suggest this treatment is optimal for increasing tomato growth and production by improving soilphysical, chemical, and biological characteristics.
