Abstract

Application of biocontrol agents on pre- and post-harvest commodities is a promising disease control strategy. This research was objected to study the potencies and antagonism mechanisms of eight isolates of yeast-like fungus Pseudozyma, i.e. P. hubeiensis Dmg 18 BEP, Dmg 20 DEP, Dmg 23 DEP, Dmg 27 BEP, and Dmg 32 DEP, P. shanxiensis Dmg 28 DEP, dan P. aphidis SG 25 BE and SG 53 BE in controlling Colletotrichum acutatum, the cause of anthracnose on chili. Those isolates of Pseudozyma were obtain from chili leaf and fruit surfaces and tissues. To study their potencies in controlling anthracnose on chili caused by C. acutatum, the eight Pseudozyma isolates were applied on chili fruit. While the study of the antagonism mechanisms was performed by antibiosis, volatile compound formation, chitinolitic activities, hyperparasitism, and ACC deaminase production tests. The results showed that all isolates of the Pseudozyma had the potencies to control anthracnose on chili caused by C. acutatum with more than 60% control levels. The mechanisms were production of volatile compounds, chitinolitic activities, and hyperparasitism. Those Pseudozyma isolates did not produce ACC deaminase.

Abstract

The Tungro disease is a significant issue that impedes rice production. It is spread by green leafhopper vectors carrying the RTBV and RTSV pathogens. The infection causes a decline in various components of rice yield and is categorized based on a scoring system ranging from 1 to 9. The objective of this study was to investigate the correlation between the scoring values and yield loss, as well as determine the production factor that had the greatest impact on yield loss for each score. The research was conducted at the IP2TP Tungro Disease Research Station between August and October 2020. A purposive sampling technique, which involved the direct observation of tungro-affected rice fields, was employed as the research method. A score was assigned to 5 clumps of plants for each case. Data analysis was performed using simple regression, correlation, and PCA. The findings indicate that with the exception of the empty grain parameter, which increased along with the scoring value, each increment in the Tungro score resulted in a decrease in the yield variables. The components of yield that declined in all scores as a result of Tungro infection included total grain weight, weight of 100 seeds, total grain count, and total grain content.

Abstract

In oil palm, Ganoderma boninense causes stem rot disease, which is often difficult to control, and soil fertility status is related to the ecology of G. boninense as a soil-borne pathogen. Therefore, this study aims to evaluate the relationship between soil fertility and stem rot disease as well as appropriate management methods to control the disease. This was carried out at the Nusantara Plantation Company's 7, Unit Kiwah Rejosari-Pematang from June 2021 to January 2022. The determination of observation blocks was carried out selectively using three blocks of land attacked by Ganoderma boninense with the same criteria for the year of planting and the same soil type. Each block consists of five plots. Each plot consisted of five sub-plots, consisting of 3 oil palms for disease severity assessment and soil sampling. The soil for each subplot was composed of 15 samples, which were analyzed for physical and chemical properties of the soil. Determination of fertility status based on the soil research manual published by the Indonesian Bogor Soil Research Center with parameters from the analysis results. The limiting factor for fertility is the cation exchange capacity of the soil, which ranges from 10.07 meq/100 g to 17.68 meq/100  g, and the C-organic content, which ranges from 0.40 to 1.15%. According to chi-square analysis, this fertility-limiting factor is related to disease severity. Therefore, management needs to be done by adding organic matter to the soil, practicing organic or inorganic fertilization, and following the principles of cultivating healthy oil palm plants.

Abstract

Space between plant (Gawangan) of immature rubber plant is one of the potential locations for the development of soybean plants. This study aims to obtain recommendations for adaptive soybean cultivation technology packages for immature rubber plantations. The research was conducted in August-November 2018 on a three-year-old rubber plantation in Gardu Village, Armajaya District, North Bengkulu Regency, Bengkulu Province. The study was conducted using a randomized block design of 4 treatments which was repeated 5 times. The data collected included the components of growth and yield of soybeans as well as input and production costs for each technology package. The growth component and yield component data were analyzed using analysis of variance and if there was a difference, then Duncan Multiple Range (DMRT) was done. The feasibility of farming is calculated from the value of the cost of revenue (R/C ratio). The results showed that the treatment had a significant effect on the number of branches, empty pods, weight of filled pods, filled seeds, seed weight per plant. However, the treatment had no significant effect on plant height, filled pods, number of pods per plant, empty or damaged seeds, number of seeds per stem, percentage of empty or damaged seeds, 1000 grain weight of seeds. All technology packages are economically feasible to develop because they have an R/C ratio > 1.

Abstract

The presence of salt levels can cause an important abiotic stress today. Plants have a special strategy for dealing with salt stress. The purpose of this study was to determine the effect of the inoculation of the arbuscular mycorrhizal fungus Glomus etunicatum on several biochemical parameters of tomato (Solanum lycopersicum L.) grown under high levels of salt stress conditions. This study used a randomized block design with a factorial pattern and five replications. The first factor was with and without inoculation of the fungus G. etunicatum. The second factor was several concentrations of NaCl (0, 50, 100 and 200 mM). Parameters observed were levels of phosphorus, root infection, concentrations of chlorophyll and carotenoids, activity of antioxidant enzymes (superoxide dismutase and catalase) and levels of malondialdehyde at the end of observation (day 45). The results showed that the increasing concentration of NaCl, decreased the levels of phosphorus, the concentration of chlorophyll and carotenoids as well increased the activity of superoxide dismutase, catalase and malondialdehyde levels. While the G. etunicatum inoculation treatment had the opposite effect from the NaCl treatment. Likewise, the parameters of root infection decreased in tomato plants inoculated with G. etunicatum with increasing NaCl concentration treatment. The conclusion of this study is that the presence of arbuscular mycorrhizal fungi can reduce the negative impact of salt stress on tomato plants.

Abstract

Soybean is one of the national strategic commodities. The increasing of soybeans needs, it is necessary to prepare the high quality seed. Different environmental conditions such as soil condition and cropping system will affect the quality of seed. The aimed of this study was to investigates the quality of soybean seed from different types of soil and cropping system. The research was conducted experimentally using Randomized Block Design (RBD) with two factors. The first factor is the source of seeds that come from two types of soil, namely peat and mineral. The second factor is seeds that come from monoculture and intercropping. Based on the results of the study, it showed that the fat and protein content of soybean seeds from seeds planted on mineral soils was better than seeds from peat soils. Planting soybean seeds in peat soil can increase the fiber and carbohydrate content of the seeds as well as the viability and vigor of the seeds. Intercropping system increased protein and fiber content of seed, but not affect its vegetative growth.
