Abstract

The combination of PGPR (Plant Growth Promoting Rhizobacteria) with bokashi aims to increase nutrient availability in the soil. PGPR which comes from paitan roots is known to have the potential to help nutrient availability so by combining it with bokashi it is hoped that it will optimize its potential in increasing tatsoi production. The bokashi used in this research were chicken manure bokashi and goat manure bokashi. Research design with two factors, namely five doses of PGPR and two types of bokashi. The PGPR doses used were 0 ml/L (D0), 50 ml/L (D1), 100 ml/L (D2), 150 ml/L (D3), 200 ml/L (D4) and two types of Chicken bokashi (A) and Goat Bokashi (K) with 5 repetitions. The observations measured were plant height (cm), number of leaves (strands) and crop diameter (cm). The results of the research showed that the combination of PGPR with bokashi chicken manure and bokashi goat manure did not have a significant effect on plant growth, namely plant height, number of leaves and crop diameter of tatsoi.

Abstract

Green chili is a large red chili that is harvested in its young phase and used for cooking ingredients. The need for chili continues to increase and the average consumption of large chili is 2.42 kg/capita/year and cayenne pepper is 2.19 kg/capita/year. The development of green chili in urban areas for household scale is constrained by limited land. The solution offered is to plant chili using planting media in polybags. This study aims to determine the composition of planting media, NPK fertilizer and their best interactions on the growth and production of green chili. The study used a Randomized Block Design (RAK) with 2 treatments, namely the composition of planting media (M) and NPK fertilizer (16-16-16) (P). The composition of the planting media was made into 4 levels, namely M0 (100% soil), M1 (50% soil + 50% rice husk charcoal), M2 (50% soil + 50% chicken manure) and M3 (50% soil + 25% rice husk charcoal + 25% manure). Each planting medium was weighed and the weight of M0 (10 kg/polybag), M1, M2 and M3 were 8 kg/polybag each. NPK fertilizer (16-16-16) was made into 4 levels, namely P0 (0 g/kg planting medium), P1 (0.112 g/kg planting medium), P2 (0.225 g/kg planting medium) and P3 (0.335 g/kg planting medium). NPK fertilizer was given together with dolomite base fertilizer 1.65 g/kg planting medium when mixing the planting medium until homogeneous and incubated for 21 days. The experiment was repeated 3 times, so that there were 16 experimental units each consisting of 3 polybags and a total of 144 polybags containing 1 (one) plant per polybag. The results obtained, the composition of the planting medium had a very significant effect on the stem diameter, a significant effect on the production of planting and per hectare but had no significant effect on plant height, number of branches and number of fruits. NPK fertilizer and its interaction with the composition of the planting media had no significant effect on all parameters. The best composition of the planting media was found in M3 and M2 which were not significantly different from each other in increasing the growth and production of green chili.

Abstract

The aim of this research is to determine the effect of seed type and automatic seeder suction pressure on seed sowing efficiency. This research was carried out at the engineering research (ER) center located in the engineering workshop, Malaysian Agricultural Research and Development Institute (MARDI) Serdang, Malaysia. With an altitude of 1,400 meters above sea level, in September 2024. This research used a non-factorial randomized block design, where each combination of seed type and suction pressure was tested three times, namely: 10 cc; 14cc; 20cc. Based on the results of tests and analysis that have been carried out on the performance of the automatic seeder for three types of seeds (chilies, shallots and cabbage) with variations in suction pressure, it has a real influence on sowing efficiency, but the influence varies depending on the type of seed. Chili seeds showed increased efficiency as suction pressure increased. 20 cc pressure gave the best results with 91.67% of seeds in the P1 category (one seed per hole). Shallot seeds show different responses to pressure variations. 14 cc pressure provides the best balance between the P1 and P>1 categories. High pressure (20 cc) causes a significant reduction in efficiency. Cabbage seeds showed consistent efficiency at low (10 cc) and high (20 cc) pressures. There is a slight decrease in efficiency at medium pressure (14 cc). Automatic seeders show significant potential to improve seeding efficiency in modern agricultural practices. However, its effectiveness is highly dependent on precise adjustments to the characteristics of the seeds used. This research highlights the importance of optimizing operational parameters of automatic seeders to maximize efficiency and productivity in the seeding process.

Abstract

Liquid Organic Fertilizer (LOF) obtained of vermicomposting processis an alternative organic fertilizer that has the potential to enhance sustainable plant growth. This study aims to investigate the effects of liquid organic fertilizer vermicompost on the vegetative growth of selected lfruity plant species, as okra (Abelmoschus esculentus) eggplant (Solanum melongena), and white radish (Raphanus sativus). The research was conducted at the Integrated Organic Farm and the Organic Laboratory of the Malaysian Agriculture Research and Development Institute (MARDI) in Serdang, Selangor, Malaysia, during September 2024. The study was carried out in two phases: field trials and laboratory tests. The field trial used a non-factorial Randomized Block Design (RBD) with four treatments, each replicated three times. The treatments of LOF vermicompost were as follows: V1 = 25% LOF; V2 = 50% LOF; V3 = 75% LOF; and V4 = 100% LOF. The laboratory tests utilized a non-factorial Completely Randomized Design (CRD) with eleven treatments, also replicated three times. The treatments were: V0 = Control (no treatment); V1 = 10% LOF; V2 = 20% LOF; V3 = 30% LOF; V4 = 40% LOF; V5 = 50% LOF; V6 = 60% LOF; V7 = 70% LOF; V8 = 80% LOF; V9 = 90% LOF; V10 = 100% LOF. The results indicated that the concentration of liquid organic fertilizer (LOF) vermicompost did not significantly affect the time of plumule emergence, the number of leaves, the fresh weight, and the dry weight in okra, eggplant, and radish. However, a significant effect was observed on plant height growth in the seedling trays. The study showed no significant differences in responses to the concentrations of LOF vermicompost among the three seed types. Nonetheless, white radish (R. sativus) exhibited better growth potential, particularly in plant height in the seedling trays. The concentration of LOF vermicompost did not significantly influence the time of plumule emergence, the number of leaves, and the dry weight in okra, eggplant, and radish. However, significant effects were observed on plant height and fresh weight in the laboratory. Overall, radish (R. sativus) demonstrated the best potential compared to okra and eggplant, especially regarding plant height and fresh weight in the laboratory.

Abstract

This study aims to analyze the effect of goat manure and liquid organic fertilizer on the growth and yield of cucumber plants. This research was conducted in the Experimental Garden of the Faculty of Agriculture, Syiah Kuala University using a Randomized Group Design (RAK) factorial pattern with two factors: the dose of goat manure consists of 4 levels, namely: K0: Without goat manure (0 ton/ha), K1: 10 tons/ha, K2: 20 tons/ha, K3: 30 tons/ha. The liquid organic fertilizer factor consists of 4 levels, namely P0: Without liquid organic fertilizer (0 ml/liter of water), P1: 5 ml/liter of water, P2: 10 ml/liter of water, and P3: 15 ml/liter of water. The parameters observed consisted of plant height, fruit number, fruit diameter, fruit length, and fruit weight. The results showed that the application of goat manure had a significant effect on plant height (15, 30, and 45 HST) and fruit length, but had no significant effect on fruit diameter, fruit number, and fruit weight. In contrast, the application of liquid organic fertilizer, either singly or in interaction with goat manure, showed no significant effect on all parameters observed. This study concludes that goat manure is effective in increasing plant growth.

Abstract

Bakanae disease caused by Fusarium fujikuroi causes high yield losses ranging from 3.0-95.4%. The use of epiphytic yeast as a biocontrol agent has the potential to control F. fujikuroi. The aim of this research is to obtain epiphytic yeast species as potential biological control agents to suppress the growth of F. fujikuroi. This research will be carried out in two stages: isolation and in vitro screening. Isolation was carried out using the systematic sampling method and screening using several tests. The parameters observed were morphological characterization of epiphytic yeast and percentage of relative inhibition level against pathogen growth (%). The result showed that shape of the epiphytic yeast cells is round, oval, rod-shaped, and budding. The color of the colonies is pink, milky white, yellow and some form pseudomycelium. The results of observations of the hight percentage of relative inhibition levels against pathogen growth in three consecutive epiphytic yeast isolates were respectively KPSL1.11 (72,44 %), KPSL1.7 (61,37%) dan KPS3 (53,57%).

Abstract

Endophytic microorganisms have become a central focus in numerous studies related to sustainable agriculture due to their dual potential as biological agents—functioning both as biocontrol and biofertilizers. The presence of endophytes within plant tissues has been shown to enhance vegetative growth, strengthen resistance against pathogenic attacks, and optimize nutrient uptake. This article presents a systematic review of recent studies from 2018 to 2024, addressing the classification, mechanisms of action, and potential applications of endophytic microorganisms in agriculture. Several bacterial genera, including Bacillus spp., Azospirillum spp., and Pseudomonas spp., along with non-pathogenic fungal groups such as Trichoderma spp. and Fusarium spp., have demonstrated effectiveness in nitrogen fixation, phosphate solubilization, phytohormone synthesis, and the production of antimicrobial compounds. Research findings indicate that the application of endophytic microorganisms as biological inputs holds great promise in supporting the development of environmentally friendly, sustainable, and high-yielding agricultural systems.
