Abstract

Mustard productivity in Indonesia tends to increase in 2019 by 10.72 tons/ha. However, this number is still below the yield potential of one of the national mustard varieties, namely the Puteri variety (PT Bintang Citra Asia), which has a yield potential of 20-25 tons/ha. An effort is needed to increase the productivity of national mustard by using liquid organic fertilizer (LOF) gamal leaves and managing the composition of the planting media. This study aims to determine the effect of the ratio between the doses of liquid organic fertilizer gamal leaves and the composition of the planting medium (soil, cow dung and husk charcoal) on polybag mustard plants. This study used CRD (completely randomized design) with 2 factors. The first factor is the planting medium (M) with 4 levels, namely soil (M0), soil + cow dung + husk charcoal = 1:1:1 (M1), 1:1:2 (M2), and 1:2:1 (M3) ). The second factor was gamal leaf POC (K) with 4 levels, namely without fertilizer application (K0), 80 ml/L (K1), 160 ml/L (K2) and 240 ml/L (K3). The data was then tested using ANOVA and 95% DMRT follow-up test. Treatment M3 and K3 were the best treatments for variable plant height, number of leaves, leaf width, leaf area index, fresh weight and dry weight. The interaction of the two M3K3 factors resulted in the highest average values for the 4 observational variables, namely plant height of 32.7 cm, leaf area index of 0.171 cm2, wet weight of 105.2 grams and dry weight of 8.57 grams. Soil, cow dung and rice husk charcoal and liquid organic fertilizer for gamal leaves can affect the growth and yield of mustard greens.

Abstract

This study aims to assess the impact of Organic FertilizerPlus on soil fertility status, nutrient uptake, and soybean yield in Alfisol. The research employs a randomized complete group design (RCGD) with a single factor, consisting of P0 (Control), P1 (Cow dung, 5 tons ha-1 + Zeolite dose of 2.5 tons ha-1), P2 (Cow dung, 5 tons ha-1 + Zeolite dose of 5 tons ha-1), P3 (Cow dung, 5 tons ha-1 + Dolomite dose of 2.5 tons ha-1), P4 (Cow dung, 5 tons ha-1 + Dolomite dose of 5 tons ha-1), and P5 (Cow dung, 5 tons ha-1 + Zeolite dose of 5 tons ha-1 + Dolomite dose of 5 tons ha-1), repeated four times. The results indicate that the application of Organic FertilizerPlus enhances soil fertility status (pH, organic C, CEC, and available P), with the highest values observed in treatment P5, including pH (6.70), soil organic C (6.28 g.kg-1), cation exchange capacity (CEC) (6.85 cmol.g-1), and available P (2.63 mg.g-1). This leads to increased phosphorus uptake, consequently improving soybean yields. The highest soybean yield is achieved by applying Organic FertilizerPlus (P5) at 2.17 t.ha-1.

Abstract

Zodia are included in medicinal plants because it contains secondary metabolites such as flavonoids, tannins, alkaloids, steroids/triterpenoids that have many benefit and also as mosquito repellents. The growth and content of secondary metabolites in plants can be affected by environmental factors such as water availability. Research on the cultivation of this crop is still limited. Environmental modification in cultivation is needed to increase its secondary metabolites, and the study of the potential of this plant as medicine are necessary. This study aimed to determine the effect of water availability on the growth and secondary metabolites of zodia. The research was carried out in July-November 2021 in Greenhouse, Faculty of Agriculture, Universitas Sebelas Maret, Surakarta. The method used was a completely randomized design, one treatment factor with 4 levels namely, 100, 80, 60 and 40% of field capacity. Each treatment was repeated 6 times so that there were 24 experimental polybags. The data analysis used is Analysis of Variance, and the Duncan’s Multiple Range Test at the 5% level. The results showed that the availability of water at a level of 60% field capacity gave the best average growth parameters (plant height and number of leaves) among other treatments. The flavonoid content in each treatment showed the same average. The results of the GCMS (Gas Cromatography and Mass Spectroscopy) test of zodia leaves showed that there were dominant bioactive compounds, namely ethylbenzene, octadecamethyl cyclononasiloxane, pentadecanoid acid and heptadecanoid acid. It is suspected that the content of these compounds has the potential as antifungal, antibacterial, antioxidant and anticancer.

Abstract

Wood vinegar is a liquid made from steam cooled wood smoke in the sublimation process. Recently, this material is known to be used as a biopesticide, so it does not have side effects that are harmful to the environment, especially for non-target insects. Ambarwati et al (2013) reported that wood vinegar can control cabbage heartworm (Crocidolomia pavonana) and has an effect in accelerating its life cycle. In addition, wood vinegar can also increase the weight of Edamame soybeans almost twice (Ramli et al, 2020) According to Sri Hartati et al (2013) wood vinegar is also able to inhibit the growth of conidium up to 76%. Mustard greens are vegetables that have good commercial value, but the production is fluctuating. One of the factors that influence the fluctuation of mustard greens production is the presence of Spodoptera litura caterpillars. The development of botanical pesticide is needed to substitute chemical pesticide. This research purposed to obtain an effective concentration of wood vinegar and an appropriate application method to control S. litura caterpillars. This research was conducted in the Laboratory of Plant Pest and Diseases Faculty of Agriculture, Sebelas Maret University (UNS) and in Satriyan, Ngrundul, Kebonarum, Klaten starting from May until August 2020. This study was conducted using a completely randomized experimental design (CRD) with two factors. First factor is concentration of wood vinegar from rice husk (0%, 2%, 4%, 8%, dan 16%) and second factor is application method (leaf dipping method and larvae spraying method). The result showed that wood vinegar with various concentrations tested has no effective effect on S. litura and application methods that used have no different effect.

Abstract

Chinese betel is a plant widely found in Indonesia, especially in the ex-Karasidenan area of Surakarta. The existence of growing Chinese betel can be found at various altitudes with humid growing conditions with low sun intensity. People in Surakarta believe that Chinese betel can be used as a traditional medicine. Chinese betel nut is suspected to contain a minerals and bioactive substances that are beneficial to health. Currently, there are few references to Chinese betel, especially related to genetic diversity. This study aims to study the diversity of Chinese betel band patterns based on RAPD markers using OPA-3, OPA-4, OPA-11, OPC-05, and OPD-4 primers. This research was carried out at the Plant Breeding Laboratory, Faculty of Agriculture, Gadjah Mada University, Yogyakarta in July - November 2023 using Chinese betel leaf DNA taken from various places in the ex-karasidenan area of Surakarta. The results of the data analyzed by NTSYSpc version 2.02 with the SimQual (Similarity for Qualitative Data) function using the UPGMA (Unweighted Pair Group with Arithmetic Averaging) method based on the Jaccard similarity index value. The amplification results showed 30 bands with 13 polymorphic bands and 17 monomorphic bands. The level of polymorphism among Chinese betel samples in the five RAPD primers used presented 44.36% of the total 13 polymorphic bands. Jaccard's genetic similarity matrix data ranged from 0.667 – 0.964. The results of the dendogram show that the sample is divided into two clusters with a diversity index of 0.28.

Abstract

The main problem in garlic cultivation was root rot disease caused by Fusarium oxysporum f.sp. cepae. Environmentally friendly control following sustainable agriculture can be used to increase plant resistance by providing biological fertilizers such as mycorrhizae and organic fertilizers such as compost and husk charcoal. This research aimed to evaluate the effectiveness of the application of mycorrhizae and organic fertilizers against Fusarium oxysporum f.sp. cepae. The research was conducted from June to November 2021 at the Tawangmangu Horticultural Seed Garden in Jl. Raya Tawangmangu, Beji, Tawangmangu, Karanganyar. Laboratory test was conducted from December 2021 to January 2022 at Laboratory of Plant Pests and Diseases and Laboratory of Soil Chemistry, Faculty of Agriculture, Sebelas Maret University. The method used was completely randomized design with a combination of mycorrhizae treatment (2 gr plant -1), compost fertilizer (16 ton ha-1), and husk charcoal fertilizer (6 ton ha-1). The data obtained were analyzed using analysis of variance and then continued with the Duncan’s Multiple Range Test. The results showed that mycorrhizae gave 22.95% effectiveness in wilting control and 20.93% in tuber rot control. Organic fertilizers provide the wilting effectiveness control by 9.27% (compost) and 8.06% (husk charcoal), as well as tuber rot effectiveness control by 27.91% (compost) and 25.58% (husk charcoal). The combination of mycorrhizae and organic fertilizers gave the highest wilt control effectiveness of 26.07% in the combination of mycorrhizae, compost, and husk bran. The effectiveness of tuber rot control was found in the combination of Mycorrhizae and compost, which was 34.88%.
