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%.

Abstract

Spodosols are widely distributed across Indonesia, covering approximately 2.16 million hectares, presenting significant potential for utilization as industrial forest plantation land, heavily reliant on its physical properties. The selection of the type of HTI plants to be cultivated depends on their adaptability. Eucalyptus is one plant known for its good adaptability to less fertile soil. This research was conducted on the land of PT. Wirakarya Sakti for 3 months, from February to April 2023, located in District 1, Betara District, Tanjung Jabung Barat Regency, Jambi Province. The aim of the research is to investigate the impact of land use planted with Eucalyptus compared to conservation forest on the physical properties of the soil. The research utilized a field survey method covering an area of approximately 326.4 hectares and the determination of points and sample collection using the stratified random sampling method. Samples were taken at locations including the conservation forest and land planted with Eucalyptus aged 1, 2, and 3 years, with 6 samples taken at depths of 0-30 cm and 30-60 cm, totaling 48 samples. Observed variables included soil texture, organic matter, bulk density, total pore space, moisture content, and permeability. The research results indicate that the physical properties of Spodosol soil include high soil volume weight due to the presence of an albic horizon in the upper layer and a spodic horizon in the lower layer, as well as high organic carbon content in the spodic horizon

Abstract

Research which aims to determine the response of several varieties of soybean plants to the time of application of phosphate fertilizer under stands of rubber plants has been carried out at the Sungai Putih Research Institute, Galang District, Deli Serdang Regency, North Sumatra Province. The method used was a Factorial Randomized Block Design method with two factors. The first factor was several soybean plant varieties (Anjasmoro, Dega 1, Dena 1, and Devon 2). The second factor was the time of administration of the phosphate fertilizer dose (111 g/plot giving phosphate fertilizer 1 week before planting, 111 g/plot giving phosphate fertilizer at planting time, and 111 g/plot giving phosphate fertilizer 1 week after planting). The parameters observed were plant height, amount of leaf chlorophyll, flowering time, number of filled pods, number of empty pods, seed weight and weight of 100 seeds. The research results showed that the treatment of several varieties had a significant effect on all observation parameters. The timing of phosphate fertilizer application had a significant effect on plant height, flowering age, number of filled pods, seed weight and 100 seed weight, but had no significant effect on the amount of leaf chlorophyll and the number of empty pods. The interaction between the two treatments had no significant effect.

Abstract

The continuous use of chemical fertilizers can reduce nutrient absorption efficiency and contribute to gas emissions that trigger global warming. One solution to increase nutrient absorption efficiency is to use nano fertilizers. This study aims to evaluate the effect of organic NPK nano fertilizer application on shallot yield. The research was conducted using a completely randomized design (CRD) arranged in a factorial design, consisting of two treatment factors with 12 treatment combinations repeated three times. Fertilization of shallot plants by applying nano NPK fertilizers up to a dose of Nitrogen 220, Phosphorus 160, and Potassium 120 kg/ha can increase the growth variables of shallot plants. The best results were obtained in the Crok Kuning variety with nano fertilizer doses of Nitrogen 220, Phosphorus 160, Potassium 120 kg/ha, and the Tajuk variety with nano fertilizer doses of Nitrogen 160, Phosphorus 100, Potassium 60 kg/ha, which produced the optimal number of tubers. However, in both Crok Kuning and Tajuk varieties, the application of nano NPK fertilizers did not have a significant effect on plant fresh weight, leaf area index, specific leaf area, relative growth rate, tuber weight per plant, and tuber diameter. Further research can be conducted with the method of fertilizer application through the leaves and using different varieties.

Abstract

Orchids are ornamental plants that have a high selling value so they are very prospective in the world of the ornamental plant business. This high economic value means that market demand for orchid commodities tends to increase. Efforts made to meet the need for orchids in the market are by propagating orchids using in vitro culture. This research aims to determine the effect of adding organic materials and NAA on the growth of orchids resulting from crossing Coelogyne pandurata and Coelogyne rumphii in vitro. This research used a completely randomized design (CRD) with two factors, namely the type of organic material (tomato, carrot and potato) and the concentration of ZPT NAA (0, 1 and 2 ppm). The research results showed that the addition of potato and tomato organic materials to the VW base medium was able to stimulate plant growth. The added NAA concentrations of 1 and 2 ppm are able to stimulate optimal plant growth. The combination of adding tomato organic matter and 1 ppm NAA concentration had the best growth in the number of roots and leaves, while adding tomato organic matter and 2 ppm NAA had the best growth in the number of shoots. The combination of adding potato organic material and 2 ppm NAA can stimulate plant height growth.

Abstract

Dendrobium spectabile is unique in that it has very diverse colors, shapes and sizes of flowers which make its market demand high but not commensurate with its production. The way to overcome this gap is with synthetic seed technology. The research design used was a completely randomized design with 2 factors, namely chitosan, which consisted of 5 levels, namely 0.05; 0.1; 0.15; 0.2% as well as control and betel leaf extract consisting of 4 levels, namely control; 1; 2; and 3%. Synthetic seeds are made with an Alginate concentration of 2.5%, starting with encapsulation and then providing chitosan soaking treatment and betel leaf extract according to the treatment. Observations were made 1 week after treatment and 3 weeks after treatment. The results show that the three-layer synthetic seeds have the characteristics of being white, non-wrinkling and dense. The lowest percentage of contamination was found in the treatment (0% chitosan + 3% betel leaf), (0.1% chitosan + 0% betel leaf), (0.1% chitosan + 1% betel leaf), (0.1% chitosan + 0.1% betel leaf). betel 3%), (chitosan 0.2% + betel leaf 0%), chitosan 0.2% + betel leaf 2%) of 25%. The cause of contamination is the fungus Rhizoctonia sp. and Aspergillus sp.. The highest shoot growth rate was found in the 0.15% chitosan + 1% betel leaf treatment. The highest number of roots was found in the treatments (0.15% chitosan + 0% betel leaf) and (0.2% chitosan + 2% betel leaf). The longest root growth was found in the treatment (0.15% chitosan + 0% betel leaf).

Abstract

The titan arum (Amorphophallus titanum (Becc.)), an endangered and endemic flora from the island of Sumatra, faces a significant risk of extinction. Conservation efforts for the titan arum were undertaken, including in vitro conservation through tissue culture. The study aimed to determine the optimal concentration of the growth regulator Benzyl Amino Purine (BAP) for inducing shoot formation in titan arum and to observe cellular changes during the shoot stage through histological test. This research was conducted from November 2023 to March 2024 at the Tissue Culture Laboratory, Andalas University. The experiment was arranged in a Completely Randomized Design (CRD) with five treatment levels: 2, 3, 4, 5, and 6 ppm.  Data analysis was performed using an F-test at a 5% significance level. If the F-test showed significant differences, further testing was carried out using Duncan's Multiple Range Test (DMRT) at a 5% significance level. Meanwhile, data on explant rooting percentage and root count were presented as means and standard deviations. Results indicated that various concentrations of BAP could induce shoots formation of Amorphophallus titanum Becc., with the percentage of explants forming shoots reaching 80–95%.  The concentration of 5.0 ppm BAP was the most effective, yielding the highest average number of shoots at 7.80. Histological test revealed cell enlargement at the shoot tips. This research is pivotal for the conservation of titan arum and promotes further studies in in vitro culture techniques.
