Abstract

Peanuts (Archis Hypogea L.) are one of the most important food sources, namely as a source of vegetable protein. This is because peanuts have high nutrition and are good for health, besides being good for health, peanuts also have a fairly high fatty acid content. This study aims to determine the effect of the number of seeds per planting hole on the growth and yield of peanut plants. This study was conducted in Boludawa Village, Suwawa District, Bonebolango Regency. The research method was carried out using a factorial randomized block design (RAK), the first factor was the number of seeds per hole (1 seed per hole, 2 seeds per hole) the second factor was the fertilization technique (tugal, larikan, sebar technique) with 3 replications and consisted of 6 treatments. Data analysis was carried out using ANOVA analysis of variance, where if the calculated f is greater than the f table, the smallest BNT test at 5% level will be carried out. The results of the study showed that the fertilization technique using the dip method had a significant effect on the growth and yield of peanut plants on plant height (4 MST), the fertilization technique using the spreading method had a significant effect on the growth and yield of peanut plants on the number of leaves (2 MST), and the weight of seeds per planting. The number of 1 seed per planting hole had a significant effect on the weight of seeds per planting.

Abstract

Bird’s eye chili is a type of plant with a very high market price. The low production of bird’s eye chili is influenced by factors such as water supply and seedling density, both of which affect plant growth and yield. This study aims to investigate the effects of water volume and seedling density per planting hole and their interaction on the growth and yield of bird’s eye chili. The study was conducted at the agricultural instrument standardization agency (BSIP) in Gorontalo Province from May to September 2024. The study used a factorial randomized bloch design (RBD). The first factor was water volume with three levels, and the second factor was seedling density with two levels. The parameters observed included plant height, leaf area, flowering age, number of fruits, and fruit wight. The data were analyzed using ANOVA followed by duncan’s multiple range test (DMRT) at a 5% significance level. Water volume significantly affected plant height, flowering age, and the weight of the first harvest fruit. In addition, No. interaction was found between water volume and seedling density for any of the observed parameters.

Abstract

The availability of high-quality mango seedlings is a major challenge in improving fruit yield and quality, which can be addressed through vegetative propagation techniques, such as grafting that combines rootstocks with strong root systems and scions from superior varieties. This study aimed to determine the effects of the interaction between cover type and rootstock height on mango grafting success. This study was conducted from July to September 2022. A split-plot design was employed, with the main factor being the cover type (single and mass cover) and the sub-factor being the rootstock height (50 cm and 30 cm). The measured parameters included the time for bud emergence, percentage of bud emergence, number of leaves, and grafting success, with data analyzed using ANOVA and LSD tests at a 5% significance level. The results showed that mass cover significantly influenced grafting success, with an average time of bud emergence of 12.40 days, percentage of bud emergence of 100%, average number of leaf average of 6.90, and grafting success rate of 100%. Conversely, the rootstock height did not significantly affect these parameters. Mass cover has been proven to create an optimal microenvironment for plant growth by maintaining humidity and temperature and protecting plants against extreme environmental conditions. In contrast, grafting incompatibility was detected in certain rootstock height treatments, potentially affecting the nutrient flow and graft quality. In conclusion, mass cover had a dominant effect on grafting success, whereas rootstock height had no significant impact. No interaction was found between cover type and rootstock height in mango grafting. Keywords: cover type, rootstock height, grafting

Abstract

Agriculture in Indonesia is generally characterized by monoculture planting systems, continuous use of fertilizers and pesticides, increased doses and frequency of application resulting in decreased fertility, structure and biotic balance of the soil, surface water and ground water pollution, are characteristics of agricultural models that are dangerous for the ecosystem and human health. Bio Input is an environmentally friendly agricultural input using existing resources to support agricultural production, economic improvement and conservation of natural resources, as well as the independence and welfare of farmers in a sustainable manner, but there are still many farmers who have not implemented it. The purpose of this activity is to apply agricultural bio-input technology through increasing knowledge and skills to groups of farmers and housewives as a sustainable agricultural action plan in Longalo Village. The methods used are socialization, training and direct practice of product making, while data analysis uses pre-test and post-test techniques. The results obtained show that bio input technology has been implemented by farmer groups and housewives in Longalo Village, as seen from the increase in knowledge and skills in: making eco-enzymes, which initially only 60.50 people knew, to 81.25 people who knew and could make them, making compost, which initially only 67 people knew, to 88.25 people who knew and could make them, and making biopesticides, which initially only 63 people knew, to 85.50 people who knew and could make them.

Abstract. Retnowati Y, Kandowangko NY, Katili AS, Pembengo W. 2024. Diversity of actinomycetes on plant rhizosphere of karst ecosystem of Gorontalo, Indonesia. Biodiversitas 25: 907-915. The objective of this study was to isolate and identify the actinomycetes associated with the rhizosphere of plants in the karst ecosystem. This study was descriptive-quantitative. Soil sampling was conducted at three locations of the karst ecosystem of Gorontalo, i.e., Bangga Hills at Bangga Bubaa Coastal area of Gorontalo District, Hills around Lake Limboto of Gorontalo District, and Oluhuta Beach Hills at Bone Bolango District. Rhizosphere-soil sample was collected from 15-30 cm of soil depth. Isolation of actinomycetes was performed using the plate method. The screening of phosphate-solubilizing bacteria was based on the ability to solubilize phosphates indicated by the clear zone on the Pikovskaya medium. Identification of actinomycetes bacteria based on morphology and molecular characters. The morphology character included the color of aerial and substrate mycelium. Molecular characteristics based on the sequence of 16S rRNA gene compared to sequence data on the gene bank of NCBI. The phylogenetic tree reconstruction was based on the Neighbor-joining algorithm. The results successfully found six isolates, including three actinomycetes isolates, two non-actinomycetes bacteria, and one yeast. They were isolated from the rhizosphere of Malastoma malabathrum, Chromolaena odorata, Cycas rumphii, Leucaena leucocephala, and Jatropha curcas. The actinomycetes isolate showed plant-growth-promoting potential indicated by solubilizing phosphate and Indole 3-Acetic Acid production activities. Based on the molecular analysis, actinomycetes were closely related to Streptomyces aegyptia (MT505707.1:42-1426), Streptomyces sp. GGCR-6 (MH718844.1:5-1391), and Streptomyces carpaticus strain PES-A23 (MH712039).

Abstract. Retnowati Y, Katili AS, Kandowangko NY, Pembengo W. 2024. Molecular identification of rhizospheric Actinomycetes from karst ecosystems of Gorontalo, Indonesia, and its seed germination induction capability of Zea mays var. doti. Biodiversitas 25: 4763-4771. Karst, as an extreme ecosystem, was a source of diverse Actinomycetes with varied biological activities. This study explored the plant-growth-promoting potential of rhizospheric Actinomycetes from the karst ecosystem of Gorontalo, with a focus on inducing seed germination in Zea mays var. doti. Four locations in Gorontalo were selected to explore Actinomycetes, targeting approximately 20 different rhizospheric plant species to isolate these microorganisms. Among the 25 isolates obtained, representing diverse morphological types from 12 rhizospheric plants, eight actinomycete isolates exhibited phosphate-solubilizing activity and produced indole-3-acetic acid (IAA). The 16S rRNA gene sequence analysis showed that approximately 75% of the isolates belonged to the Streptomyces genus, including Streptomyces cavourensis strain KRZm-02, Streptomyces sp. strain KRZm-03, Streptomyces pratensis strain KRLl-01, Streptomyces carpaticus strain KRIt-01, Streptomyces sp. strain KRIt-02, and Streptomyces aquilus strain KRPa-01. Additionally, 12.5% of the isolates were identified as Nocardiopsis alba strain KRZm-01 and Micromonospora sp. strain KRPt-01, respectively. The two isolates with the highest plant-growth-promoting potential, Streptomyces pratensis strain KRLl-01 and Streptomyces carpaticus strain KRIt-01, were further tested for their ability to promote germination of Zea mays var. doti seeds over 7 days. Among the two, Streptomyces carpaticus strain KRIt-01 exhibited the highest germination-inducing potential. Overall, the karst ecosystem of Gorontalo offers a valuable reservoir of biological resources with the potential for Plant-Growth-Promoting Rhizobacteria (PGPR). Further studies on the application of these actinomycete isolates as biofertilizers in agricultural and plantation crops could significantly contribute to improving crop growth and productivity, thereby revolutionizing agricultural practices.
