Abstract

Cucumber (Cucumis sativus L.) is rich in nutrients and vitamins, an is popular for fresh salads and various processed foods. The objective of this work is to study the effects of branch pruning and NPK fertilizer dose on the growth and yield of baby cucumber in order to solve the decrease in cucumber production. The research was executed in Dander Village, Bojonegoro Regency, East Java. The experiment was performed according to a Randomized Block Design with two factors. The first factor is branch pruning, and the second factor is the dose of NPK fertilizer. Branch pruning was carried out in four ways: no pruning, pruning branches at nodes 1–3, nodes 1–4, and nodes 1–5. The NPK fertilizer dose was also applied at four levels: 800, 900, 1,000, and 1,100 kg/ha. The observed parameters included plant length, number of leaves, time to female flower appearance, fruit length, number of fruits per plant, total fruit weight per plant, and fruit weight per hectare. The data were analyzed using analysis of variance (ANOVA) and tested with HSD at 5%. The results showed that the combination of no pruning and the application of 1,100 kg/ha NPK fertilizer produced the best results in terms of fruit weight per hectare.   Keywords: Baby cucumber, Branch pruning, Harvest, Macro-nutrients, Photosynthate translocation.

Abstract

Cayenne pepper cultivation in urban areas faces several obstacles, including infertile soil, irregular watering due to busy daily activities, pests and diseases that spread more easily in urban areas, and high temperature changes. This study aims to obtain the optimal concentration of paclobutrazol and Gandasil fertilizer for the development and production of cayenne pepper. This study used a factorial completely randomized design with two factors, namely paclobutrazol concentration consisting of 4 levels (0 ppm, 75 ppm, 100 ppm, and 125 ppm) and Gandasil B/D fertilizer consisting of 4 levels (1 g/L, 2 g/L, 3 g/L, and 4 g/L). Results showed that treatment combination of paclobutrazol 100 ppm and Gandasil 3 g/L gave the best results on the number of flowers per plant (822.0), number of fruits per plant (144.5), and fruit weight (156.77 g/plant). This combination may, however, result in low fruit yield and inhibit vegetative development, including leaf number and plant height. The fastest flowering age was obtained at combination paclobutrazol 125 ppm and Gandasil concentrations of 4 g/L with a value of 39.33 days.   Keywords: Concentration, Gandasil fertilizer, Growth, Paclobutrazol, Yield.

Abstract

The demand for avocados in Indonesia continues to rise, while the availability of high-quality seedlings remains limited. Propagation through stem cuttings with the application of IBA (Indole Butyric Acid) is expected to improve propagation success. This study aims to determine the effect of IBA concentration on the growth of avocado stem cuttings. The research was conducted in Bojonegoro, East Java, using a Completely Randomized Design (CRD) with one factor, namely five concentrations of IBA: 0, 75, 100, 125, and 150 ppm. Observed parameters included shoot length, number of shoots, number of leaves, and number of primary roots. The results showed that IBA concentration had a significant effect on all observed parameters, while cutting length had no significant effect. A concentration of 100 ppm produced optimal growth of 1.92 cm, 2.50 shoots, and 4.33 leaves. The treatment without IBA resulted in the lowest values. The application of IBA at concentrations of 75–100 ppm effectively enhanced the growth of avocado stem cuttings, particularly in shoot and leaf development.

Abstract

Rice (Oryza sativa L.) is the primary staple food crop and a strategic source of carbohydrates for the Indonesian population. In recent years, rice production has declined at both national and local levels due to climate change, land limitations, and pest disturbances. This condition highlights the urgent need for research to develop more efficient and sustainable rice cultivation strategies. This study aimed to determine the interactive effects of planting systems and Paclobutrazol concentrations on the growth and yield of the rice variety Inpari 32. The research was conducted in Ngraho District, Bojonegoro Regency, East Java, using a Split Plot Design with two factors: planting systems (Tegel/traditional, SRI, Legowo 2:1, and modified Legowo) and Paclobutrazol concentrations (0, 600, 700, and 800 ppm). Observed parameters included plant growth and yield components. The results revealed significant interactions between planting systems and Paclobutrazol concentrations on several parameters, including the number of panicles, panicle length, and grain weight per cluster. The best results were obtained with the modified Legowo system combined with 600 ppm Paclobutrazol, which produced yields exceeding 6 tons per hectare. This combination is recommended as an effective cultivation strategy to enhance rice productivity and support sustainable national food security.

Abstract

Efforts to improve the quality of the Anjasmoro soybean variety (Glycine max L. Merrill) include the use of seed coating techniques. Seed coating involves applying a layer of specific materials to seeds, serving as carriers for additional substances that extend seed shelf life, protect against pathogens, and stimulate plant growth. This study aimed to identify the most effective seed coating material to enhance soybean growth after storage for three months. Growth tests were conducted using the following treatments: FP 0 (control); FP 1 (CMC 1.5% + Liquid Smoke 0.5% + CaCO₃ 72 g + Gypsum 18 g); FP 2 (CMC 1.5% + Liquid Smoke 0.5% + CaCO₃ 72 g + Talc 18 g); FP 3 (CMC 1.5% + Liquid Smoke 0.5% + CaCO₃ 72 g + Pumice stone 18 g); FP 4 (CMC 1.5% + Liquid Smoke 0.5% + CaCO₃ 72 g + Quicklime 18 g); FP 5 (CMC 1.5% + Liquid Smoke 0.5% + CaCO₃ 72 g + Dolomite 18 g); and FP 6 (CMC 1.5% + Liquid Smoke 0.5% + CaCO₃ 72 g + Zeolite 18 g). Observations included plant height (cm), number of leaves, and number of branches. The study was conducted from April to October 2024 at the UPT Center for Rice and Secondary Crops Seed Development 2, Singosari District, Malang, using a randomized block design (RAK) with seven formulations of seed coating materials. Each treatment consisted of 16 plants with four replications. The research data were analyzed using ANOVA, followed by a BNJ (Honestly Significant Difference) test at the 5% significance level (BNJ 0.05). The results showed that the FP 1 treatment resulted in a plant height of 56.50 cm, 19.75 leaves, and 4.75 branches at 35 days after planting (DAP). The FP 1 treatment significantly enhanced growth, as indicated by plant height, leaf number, and branch number. FP 1 demonstrated the best combination of seed coating materials compared to other treatments at 21, 28, and 35 DAP

Abstract

Tomatoes (Lycopersicum esculentum Mill.) are a horticultural commodity with high economic value, but theirproductivity is often hampered by flower and fruit loss. Increasing growth and yield can be achieved throughpotassium fertilization, which plays a role in photosynthesis and fruit formation, and through the application ofthe growth regulator paclobutrazol, which suppresses vegetative growth and stimulates the generative phase. Thisstudy aims to evaluate the effects of potassium fertilizer dose and paclobutrazol concentration, and theirinteractions, on tomato growth and yield. The study was conducted in Surabaya from November 2024 to February2025 using a factorial Randomized Block Design with two factors: potassium fertilizer doses (110, 125, 140, 155kg/ha) and paclobutrazol concentrations (0, 100, 125, 150 ppm), each factor repeated three times. The resultsshowed that the combination of 140 kg/ha potassium fertilizer and 125 ppm paclobutrazol produced the highestnumber of leaves (37), number of bunches (6.78), total number of fruits (37.67), and total fruit weight per plant(1,509.27 g). Potassium fertilizer at 140 kg/ha alone produced the highest number of flowers (69.41), whilepaclobutrazol at 125 ppm accelerated flower emergence (34.53 days), increased the number of flowers (69.77),and increased fruit weight per harvest period. Thus, using 140 kg/ha of potassium fertilizer combined with 125ppm paclobutrazol is recommended as the most effective treatment to optimize tomato plant growth and yield.

Abstract

Background: Purple eggplant (Solanum melongena L.) is a high-value nutritional crop with significant market demand. However, production in Indonesia fluctuated between 2021 and 2023; after reaching a peak of 551,552 tons, yields dropped to 510,749 tons in 2023. This decline is largely attributed to the excessive use of synthetic fertilizers. This study aims to evaluate the interactions and effects of integrating goat manure with various liquid organic fertilizers (LOF) on purple eggplant growth. Furthermore, this research seeks to establish sustainable cultivation practices that reduce chemical dependency in horticulture. Methodology: This research followed a Factorial Randomized Block Design (RBD) with two factors and three replications. The first factor was the goat manure dosage at four levels: 0 g/plant (control), 500 g/plant, 750 g/plant, and 1,000 g/plant. The second factor consisted of four types of liquid applications: NPK 16:16:16 (control), eco-enzyme LOF, banana peel LOF, and cabbage waste LOF. Observation data were analyzed using Analysis of Variance (ANOVA), followed by Tukey’s Honestly Significant Difference (HSD) test at a 5% significance level where significant effects were detected. Findings: The results showed that the combined treatment of goat manure dose of 1,000 g/plant and banana peel LOF gave the best results in the parameters of plant height (46.67 cm), number of leaves (16.33 leaves), total fruit number per plant (11.72 fruits), and total harvest weight per plant (1635.94 grams) compared to other organic combination treatments. Contribution: The combination of goat manure and banana peel liquid organic fertilizer (LOF) emerged as the most effective treatment compared to other organic combinations. This organic treatment resulted in a 28% yield increase over the control. Althought this specific increase was not statistically significant, the study strongly recommends organic fertilizers as a sustainable and eco-friendly alternative to reduce inorganic fertilizer dependency in horticultural farming systems
