Abstract

Basil can be grown in all regions of Indonesia. The purpose of this study was to identify the response of 2 types of basil against the use of N fertilizer dose on the early growth. In the growth process, plants require sufficient nutrients so that the physiological processes in plants’ organs can be held properly. The nutrients used by plants can be sourced from within the soil itself or in the form of fertilizers that have been put into the soil. Plants will grow properly if the elements needed by plants are fulfilled. The research was carried out from February to April 2022 at the Experimental Field of the Faculty of Agriculture and Animal Husbandry at the University of Muhammadiyah Malang. The design used in this study was the factorial Randomized Complete Block Design (RCBD) with a treatment dose of Urea fertilizer in basil type. The results showed that there was no interaction between the types of basil and the dose of urea at all the observation parameters. On the other side, the type of basil affects the parameters of the number of leaves, plant height, and total fresh weight where the type of tidore basil was better than other types of basil. Furthermore, the urea fertilizer dose treatment affected the number of leaves, plant height, and total fresh weight where the better urea fertilizer dose was N125.

Abstract

The research aimed to explore the impact of vermicompost fertilizer dosage and application timing on kale (Brassica oleracea var. Acephala) varieties. Conducted in Sukoharjo Village from July to September 2020, the study implemented a Randomized Complete Block Design with two factors: vermicompost dosage (D0: NPK 2 g/plant/untreated, D1: 250 g/plant, D2: 500 g/plant, D3: 750 g/plant) and application time (T1: planting, T2: 7 days after planting, T3: 14 days after planting). Analysis revealed no interaction between dosage and application time. Doses of 250 g (D1), 500 g (D2), and 750 g (D3) significantly differed in plant height, leaf number, stem diameter, leaf area, and fresh and dry weights. Notably, the application time at planting (T1), 7 days after planting (T2), and 14 days after planting (T3) significantly affected leaf number. In conclusion, the study found no interaction effect between vermicompost dosage and application time on kale. Doses of 250 g, 500 g, and 750 g exhibited significant differences, impacting plant growth and dry weight. Application times at planting, 7 days after planting, and 14 days after planting significantly influenced leaf number. These findings emphasize the importance of proper dosage and timing for optimizing kale growth with vermicompost fertilizer, contributing to sustainable agricultural practices.

Abstract

Cucumber (Cucumis sativus L.) is one type of vegetable from the cucurbitaceae family that has been grown by farmers in Indonesia. The research was conducted for 4 months from September 23 to December 13, 2022 in one of the experimental fields owned by PT Aditya Sentana Agro. The purpose of this study was to determine whether the 2 candidate varieties CI-88 and CI-87 of kyuri cucumber tested would show significant differences in characters from 3 comparison varieties F1 MK 01, F1 MK 02, F1 MK 03 and to determine whether the results obtained from the 2 candidate varieties CI-88 and CI-87 of kyuri cucumber to be used as varieties and produced. This study consisted of 2 genotypes of hybrid variety candidates CI-88 and CI-87 and 3 comparison varieties namely F1 MK 01, F1 MK 02 and F1 MK 03 which were used as treatments. The three comparison varieties were used because they were in high demand in the market so that they had a high selling value and had a good response from farmers. Qualitative characteristics observed were stem shape, leaf shape, flower color, fruit shape, fruit skin color, fruit flesh color, and fruit taste test. The results of observations of qualitative character traits are presented in the form of tables and picture documentation. The results of quantitative characterization observations include stem diameter, fruit weight per plant, fruit weight per fruit, fruit diameter, fruit length, number of fruits per plant, leaf width, leaf length, age from flowering and age from harvest. The results of the two candidate varieties tested have the opportunity to be developed and registered as new varieties because the results obtained are comparable to the comparator varieties already on the market..

Abstract

Strawberries (Fragaria sp.) are a popular fruit and have high commercial value worldwide. Strawberry production continues to increase, but challenges related to temperature and environment affect fruit growth and quality. Temperature is a major factor in strawberry growth. Increased temperature can also affect fruit size, weight, and color, as well as sweetness. This study used a literature search method to analyze the impact of temperature and environment on strawberry growth. To overcome these challenges, the use of greenhouses is one of the appropriate techniques for climate engineering. Greenhouses create suitable temperature conditions and protect plants from adverse climatic conditions and can maintain optimal temperatures for strawberries. Nonetheless, it is necessary to consider the use of shadin g techniques in greenhouses. Relative humidity also plays an important role, and dehumidification techniques, such as dehumidification ventilation, are required to maintain optimal internal conditions.

Abstract

A. glycine soybean infestation caused yield loss reaching 58%. Environmental friendly controls are carried out using natural ingredients. This study was conducted to determine the effectiveness of the combination of gadung and grass grinting tuber extracts on soybean virus (A. glycine) vector pests and to know the mechanism of toxicity to these pests. This research was conducted from June to September 2018. The effectiveness of applications using simple Randomized Completed Block Design (RCBD). Analysis of Varian at 5% level, and Duncan's Multiple Range Test (DMRT) test. Calculations of LC50 and LT50 use probit regression analysis. The results showed that the highest compounds contained in gadung tubers were alkaloids, whereas in grinting grasses were saponins. Both of these compounds have the potential as a base for vegetable insecticides. The combination treatment of gadung extract and grinting 3: 2 (v / v) (P7) and 3: 1 (P8) showed the most effective results compared to positive controls and other treatments with mortality mean values at all observations of 87.44% and 86, 7%. The LC50 value of gadung extract at the first observation was 3%, the grinting extract was 3.08%. The lowest LT50 value is in treatment P7 (3: 2) with a time of 3.88 hours. a combination of gadung extract and grinting can suppress A.glycine infestation and potentially a plant-based insecticide.

Abstract

This study examined the effect of growing media and the combination of PGR concentration and soaking time on root induction in Lipstick Aglaonema (Aglaonema crispum L.). The study aimed to evaluate the interaction between growing media and the combination of PGR concentration and soaking time on root induction in Lipstick Aglaonema, as well as to identify the optimal growing medium that meets export standards for this plant. The experimental design used was a Factorial Randomized Block Design (RBD), where factor 1 was the combination of PGR concentration and soaking time: K1 (water), K2 (Atonik 2 ml/l for 20 minutes), K3 (Rootone-F 200 mg/l for 1 hour), K4 (Prokar PGR 10 ml/l for 15 minutes), K5 (Prokar PGR 10 ml/l for 30 minutes), and K6 (Prokar PGR 10 ml/l for 45 minutes). The second factor was the growing media: M1 (a mix of manure, cocopeat, soil, rice husk, and charcoal), and M2 (a mix of cocopeat and rice husk charcoal). There was an interaction between the growing media and the PGR concentration and soaking time on leaf area and stem diameter parameters. The longer soaking treatments using Prokar PGR for 15 and 30 minutes were more effective for enhancing the growth of Lipstick Aglaonema cuttings in terms of the number of roots and root length. However, the growing media did not significantly affect all observed parameters.

Abstract

Porang (Amorphophallus muelleri Blume.) is a type of tuber plant that is widely available in Indonesia and has tremendous potential and prospects to be developed in Indonesia. Porang is widely exported from Indonesia to several countries. The demand for porang exports continues to increase while the production of porang is still low. In vitro culture is an alternative solution in porang plant propagation to meet the needs of many porang seeds and in a relatively short period of time. Provision of growth regulators in the media can affect the growth of porang. This study aims to obtain information whether there is an interaction between IBA and TDZ in the media, to obtain information on the effect of adding IBA and TDZ with different concentrations on the growth of porang plantlets. This research was conducted using MS medium which was then added with IBA with a concentration of 0.5 ppm, 1 ppm and added PGR TDZ with a concentration of 0.5 ppm, 1 ppm and 1.5 ppm. The results of this study showed that there was no significant difference between the emergence of shoots and the time of emergence of leaves from all treatments. The I1T3 treatment (IBA 0.5 ppm + TDZ 1.5 ppm) was the best combination treatment in this study by showing the fastest root emergence time (6 MSI), the highest average number of shoots (7.25 shoots), the average number of shoots the highest number of roots (3.67 roots), the highest average number of leaves (6 strands) and the highest average shoot height (1.33 cm).

Abstract

The The bambara groundnut has the potential to continue to be developed, but the obstacle faced is the very limited availability of bambara groundnut seeds. This is because there are no varieties from the results of breeding that are released and the low quality of the seeds. Low seed quality is caused by slow germination and results in the seed growth process being non-unison, this is influenced by seed dormancy. The purpose of this study was to determine the effect of soaking time in KNO3 on germination, vegetative morphology, and crop yield in the field by measuring seed viability and vigor, vegetative morphology and yield. The research was carried out for 4 months, from June-October 2022 which took place at the Agrotechnology Laboratory of the Muhammadiyah University of Malang and Dadaprejo Land, Batu City. The study was conducted using a simple Completely Randomized Block Design (RKLT) consisting of 10 treatments, and was repeated 3 times. The observed variables included moisture content, DB, PTM, IV, KCT, T50, plant height, number of leaves, leaf shape, leaf color, stem color, pod color, pod shape, number of pods, pod dry weight, number of seeds, dry weight seeds, yield potential, and weight of 1000 seeds. The results showed that the long soaking of seeds in KNO3 did not affect their vegetative morphology. Soaking time of seeds in KNO3 had no significant effect on DB and PTM values, but had a very significant effect on IV values, the number of leaves in the vegetative and generative phases. And it has a significant effect on the height of the KCT, T50, and plant height in the vegetative phase. As for the yield variable, the results showed no significant effect. Soaking time in KNO3 only affected germination, plant height, and number of bambara groundnut leaves.

Abstract

In Indonesia, pineapple is one of the horticultural commodities that has the potential to be developed. It is seen that the amount of demand for fresh pineapple from abroad is quite high. Intensification of pineapple land is still lacking where the number of pineapple seedlings planted has only reached 2,500 from ideally 10,000 stems per hectare. Alternative to overcome this problem is by propagating plants in vitro through callus induction which later is thought to potentially have quality and quantity seeds as expected. This study uses a combination of ZPT 2,4-D and cytokines which are expected to grow callus with good quality and relatively faster time.This study uses Factorial Randomized Block Design (RBD). By using the first factor namely 2,4-D concentration and the second factor cytokines (BAP and TDZ). The data can be analyzed for variance and a real honest test (BNJ) level of 5%. Based on the results of the study, it was found that the combination of giving concentrations to 2,4-D and cytokines was not significant for each parameter. The interaction between 2,4-D growth regulators and cytokinins has no significant effect on the induction of pineapple varieties of Smoooth cayenne. The treatment of 2,4-D 0 mg/L - 5 mg/L growth regulators has no significant effect on callus induction in vitro on the Smoooth cayenne varieties. The treatment of cytokinin (Thidiazuron 0.001 mg/L - 0.1 mg/L and BAP 0 mg/L - 4 mg/L) had no significant effect on in vitro callus induction on the Smoooth cayenne varieties.

Abstract

Potatoes (Solanum tuberosum L.) are carbohydrate-rich crops. Low potato productivity in Indonesia stems from farmers' inadequate access to quality seed potatoes. One solution to this issue is enhancing quality seed potato production, achievable through aeroponic systems. Lighting, whether incandescent or LED, can optimize potato mini tuber propagation in aeroponic systems. Research on lighting's effects on potato growth remains incomplete. This study aims to investigate how lighting color and duration affect mini tuber production of Solanum tuberosum L. PPT4 Zebra using aeroponic systems. Conducted in Jurangkuali, Bumiaji sub-district, Batu, the study employed a split plot design. The main plot consisted of lighting colors (WC): light yellow (WK), white (WP), and purple (WU). Subplots were lighting duration (LP) at 3 hours (LP 3) and 5 hours (LP 5), each replicated four times. Each replication comprised 8 samples, with 18 potato plant cuttings per population. Variables included plant height, stem diameter, leaf count, chlorophyll level, root length, tuber count, tuber diameter, budding seed count, and tuber weight. Data were analyzed using F-tests followed by BNJ tests at a 5% significance level. Results indicated no interaction between lighting color and duration. Purple lighting yielded the highest tuber count and weight, while 3-hour lighting duration yielded superior plant height, stem diameter, leaf count, and root length.
