Abstract

Porang (Amorphophallus onchophyllus) has many benefits for industry and health, because of the high content of glucomannan in its tubers. Porang needs to be developed, but the problem is getting a uniform source of tuber seeds. To get the uniform tuber seeds by dividing them. This study aims to get a uniform source of tuber seeds. This study was conducted in the field and laboratory. The experiment was arranged in a CRD. There are two factors, in seed tuber division: U1= Intact tuber, U2=Tuber cut in 2, U3=Tuber cut in 3 parts, and U4=Tubers cut into 4 parts. The second factor is fertilizer consisting of Urea, Za, and Phonska. The results of the combined treatment between tuber division and fertilizer treatment showed no significant interaction in all observed parameters. The seed tuber division treatment affects the bud break time, plant height, stem diameter, and canopy width, only at the beginning of growth. U1 gives the highest growth. The various fertilizer treatments only had a significant effect on plant height and stem diameter at 7 and 8 WAP. The treatment of splitting tuber seeds can replace intact tubers to be used as Porang tuber seeds

Abstract

Long bean (Vigna sinensis L.) is a valuable vegetable commodity recognized for its high nutritional value; however, its production in Indonesia has declined. This decrease can be attributed to improper cultivation techniques. To enhance production, strategies such as NPK fertilization and the application of growth regulators, specifically gibberellic acid (GA3), can be employed to improve yields. The combination of these two methods has the potential to improve both the growth and yield of long beans. This study employed a randomized complete block design (RCBD) with two factors, where each treatment combination was replicated three times. Data analysis was conducted using analysis of variance (ANOVA). This research aims to provide insights and recommendations regarding the most effective doses of NPK fertilizer and GA3 concentrations to enhance growth and yield. Specifically, it seeks to determine the optimal concentration of GA3 that promotes the growth and yield of long bean plants. The combination of NPK fertilizer and GA3 had a significant influence on the growth and yield of long bean plants. The treatment of NPK at 15 g/plant combined with GA3 at 100 ppm resulted in increased plant height, while NPK at 5 g/plant combined with GA3 at 100 ppm led to a higher number of fruits. Additionally, the combination of NPK at 15 g/plant and GA3 at 150 ppm significantly increased pod weight. Furthermore, the individual treatments of NPK at 15 g/plant and GA3 at concentrations ranging from 100 to 150 ppm also positively affected the growth and yield of long bean plants.

Abstract

The productivity of long beans (Vigna sinensis L.) in Indonesia remains low due to an imbalance between vegetative and generative growth, with long bean production experiencing significant fluctuations between 2017 and 2022, dropping to 352,700 tons in 2019 and rising again to 360,674 tons in 2022. Research on the use of paclobutrazol and NPK fertilizer on long beans is generally conducted separately, so information regarding their interaction on fruit set and productivity remains limited. Therefore, this study aims to evaluate the interaction between paclobutrazol concentration and Phonska Plus NPK fertilizer dose on the growth and yield of long beans (Vigna sinensis L.), as well as to determine the most effective treatment combination for improving the plants' generative performance. The study employed a two-factor randomized block design (RBD) with four levels of paclobutrazol (0, 100, 150, 200 ppm) and four levels of Phonska Plus NPK fertilizer (250, 300, 350, 400 kg/ha), each replicated three times. Data were analyzed using analysis of variance (ANOVA) and followed by a BNJ test at the 5% level if significant effects were found. The results showed significant interactions for plant height at 14 and 56 days after sowing (DAS), pod number in the 2nd and 3rd weeks of harvest, pod weight per plot, and fruit set. The combination of 150 ppm paclobutrazol and 400 kg/ha NPK Phonska Plus yielded the highest fruit set at 86.92% and high pod weight. Physiologically, a moderate dose of paclobutrazol effectively suppressed vegetative growth in a controlled manner, allowing for more efficient distribution of photosynthates to the generative organs, while sufficient levels of N, P, and K enhanced photosynthetic activity and the pod-filling process. This study demonstrates the synergy between hormonal regulation and balanced fertilization in enhancing the generative performance of long beans, and provides recommendations for effective dose combinations to support more efficient and targeted productivity improvements

Abstract

Hydroponics serves as an alternative to conventional land-based agriculture. This technique enables the cultivation of vegetables in regions with poor fertility or limited space and high population density. The hydroponic planting system's advantage is based on its ability to precisely regulate nutrients. Ensuring adequate nutrition will yield optimal outcomes and be economically efficient. A hydroponic system has long been used to grow pakchoy and samhong plants. The purpose of this study is to ascertain how best to utilize AB-Mix nutrition to achieve the best growth possible for both varieties of mustard. The experiment uses a Completely Randomized Design (CRD) factorial. The first factor are concentrations of AB-mix, 1000 ppm, 1200 ppm, and 1400 ppm. The second factor is Brassica spesies are samhong and pakcoy. There are six treatment combinations, and they were repeated five times. Observations on plant height and leaf number are carried out for four weeks. ANOVA was used to test the observation data, and DMRT was used for additional testing. The pakcoy and samhong plants' plant height were best achieved when an AB-Mix concentration of 1200 ppm was used.

Abstract

Cucumber (Cucumis sativus L.) is a vegetable from the Curcubitaceae family or gourds that originated in India and has spread throughout the world including Indonesia. In Indonesia, cucumber is one of the vegetables that is much favored by all levels of society because it can be consumed and used as a cosmetic and medicinal ingredient. This study aims to determine the effect of gibberellin concentration and NPK fertilizer dosage on the growth and yield of cucumber plants. The research was conducted in Dasri Village, Tegalsari District, Banyuwangi Regency, East Java,  from August to November 2024. This research was conducted using the method of Divided Plots Design (RPT) with two treatment factors. The treatments used were concentration of gibberellin as main plot and dosage of NPK fertilizer as sub plot. The concentration of gibberellin consisted of four levels, namely: 0 ppm/plant, 100 ppm/plant, 200 ppm/plant and 300 ppm/plant. The second factor is the dose of NPK fertilizer including: 100 kg/ha, 400 kg/ha, 500 kg/ha and 600 kg/ha. The results showed that the treatment combination of gibberellin concentration of 300 ppm/plant with NPK fertilizer dosage of 600 kg/ha affected to length of plant and total of leaves.
