Abstract

Currently, seaweed extracts are widely used as plant biostimulants to increase the efficiency of nutrient use, tolerance of abiotic stress, and improve plant quality. In this study, tested the effect of different Padina minor seaweed extract formulas (liquid extract and powder extract) and the frequency of application of Padina minor seaweed extract (b0 = control; b1 = 1 x application; b2 = 2 x application; and b3 = 3 x application) as a biostimulant to the growth of upland rice. From the results of the study, it was found that there was no significant effect of the application of the two extract formulas and the frequency of application, but the administration of Padina minor extract 3 times during vegetative growth increased all growth parameters, such as: plant height, number of tillers, fresh and dry weight of plants, and chlorophyll content. It was concluded that giving Padina minor extract 3 times could increase the vegetative growth of upland rice effectively.

Abstract

Biostimulants are formulations of organic compounds derived from plants or microorganisms and can increase the efficiency of nutrient absorption, tolerance of abiotic stress and plant productivity. Padina minor contains high levels of macro and microelements, growth-regulating hormones and secondary metabolites. Centella asiatica contains secondary metabolites, essential oils, and amino acids. This study aims to determine the effect of seaweed extract Padina minor, Centella asiatica and a combination of extracts Padina minor and Centella asiatica on the growth of soybean plants grown on ultisol soil. This study used a completely randomized design (CRD) with 4 treatments with 6 replications. This treatment consisted of Padina minor, Centella asiatica and a combination of Padina minor and Centella asiatica. The results showed that the administration of Padina minor extract had an effect on increasing plant height, while Centella asiatica extract had an effect on leaf area and the combination of Padina minor and Centella asiatica extracts had an effect on increasing plant height, number of leaves, leaf area and wet weight of soybeans planted. on ultisols.

Abstract

Biostimulants are organic compounds which in small amounts can have a positive effect on plant growth. Plant extracts are a source of biostimulants which contain compounds such as secondary metabolites and other organic compounds that can enhance plant growth. Portulaca is a wild plant that contains secondary metabolites, amino acids, macro and micro nutrients which have the potential as a source of biostimulants. Kale is a vegetable from the Brassicaceae family which is known as a super food because of its health benefits. Efforts to improve the quality of Kale production need to be increased in line with public demand. This study aims to analyze the effect of giving several concentrations of Portulaca extract and its compatibility on Kale growth. The method used in this study was an experimental method with a completely randomized design (CRD) with 5 treatments and 5 replications. Some concentrations of Portulaca extract are as a treatment consisting of: A (0%); B (1.5%); C (3%); D (4.5%); and E (6%). The application of Portulaca extract had a significantly different effect on chlorophyll and total chlorophyll of Kale plants with the highest content of 0.822 and 1.462, but did not have a different effect on other growth parameters. Based on proximate analysis, increasing the concentration of Portulaca extract can increase the highest percentage of protein content, namely at a concentration of 6% by 23.75%.

Abstract

Using biostimulants in plant cultivation can increase plant growth and make plants more stress-resistant. Plant extracts are one source of natural biostimulants such as Moringa (Moringa oleifera L.), which contain secondary metabolites and plant growth hormones. In the process of plant extraction, the type of solvent used affects the quality of the resulting extract. This study aimed to determine the effect of biostimulants of Moringa leaf extract extracted with several types of solvents on the growth of red spinach (Amaranthus tricolor L.)  This research was conducted from March to April 2022 in the Greenhouse and Plant Physiology Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Universitas Andalas, Padang. This study used a Completely Randomized Design (CRD) with four treatments and eight replicates. As treatment is a solvent for extracting moringa leaves consisting of without extract (A), Distilled water (B), Methanol (C), and Ethanol (D). The results showed that the solvent used to extract moringa leaves gave a significantly different effect on the number of leaves but had no significant effect on plant height, leaf area, root length, wet weight, dry weight, chlorophyll content, and anthocyanin content of red spinach plants. Extraction of moringa leaves with methanol and ethanol increases the number of red spinach leaves, which is  14.1 strands.

Abstract

Magnaphorte oryzae is a pathogenic fungus that causes blast disease in rice plants. This disease can cause a decrease in rice production. Therefore, it is necessary to control the disease, one of which is by administering microbes that are antagonistic to Magnaphorte oryzae. This research aims to determine the percentage of inhibitory power of Bacillus subtilis ATTC 6633 and Trichoderma harzianum on the growth of Magnaphorte oryzae with varying soaking times of 24, 48 and 72 hours on the Anak Daro rice variety. This research carried out viability tests for Bacillus subtilis ATTC 6633 and Trichoderma harzianum, as well as antagonist tests using the dual culture method. The results showed that the growth inhibition of Magnaphorte oryzae by Bacillus subtilis ATTC 6633 for a soaking period of 24 hours was 28.48% in the weak category, 48 hours was 32.27% and 72 hours was 31.01% in the medium category. Inhibition of Magnaphorte oryzae by Trichoderma harzianum for a soaking period of 24 hours was 50.63%, 48 hours was 57.59%, and 72 hours was 56.32% in the high category.

Abstract

Dendrobium lasinthera is an orchid that has considerable potential as a raw material for anti-cancer drugs and for the production of cut flowers. Therefore, this orchid is a plant with high economic value. This orchid has beautiful and long-lasting flowers. The demand for this orchid is increasing along with its diverse uses, so the propagation of this orchid needs to be increased. In vitro propagation is the most appropriate step to reproduce this orchid. One of the stages that determines the success of orchid propagation through tissue culture is the root induction stage before acclimatization. Using the right type and concentration of Growth Regulatory Substances (ZPT) is very important. This research aims to determine the effect of several NAA Growth Regulatory Substance (ZPT) concentrations and determine the best NAA concentration for Dendrobium lasianthera root induction. This study used a Completely Randomized Design (CRD) with several NAA concentrations (Control (A); 0.5 mg/L (B), 1 mg/L (C), and 1.5 mg/L (D)), on Murashige & Skoog (MS) media. The results of this study show that NAA has a significant influence on the percentage of root formation, root emergence time, and root length in the Dendrobium lasianthera orchid. NAA 1.5 mg/L is the best concentration for induction of Dendrobium lasianthera orchid roots.
