Abstract

ABSTRACT Onion is one of the vegetable commodities that have significance for the community, both from economic value and nutritional content. In the last decade the demand for onion for consumption and for domestic seeds has increased, so that Indonesia must import to meet those needs. The production and quality of onion shall always be enhanced through intensification and extensification. Induction of mutation as one of the methods of plant breeding to obtain genetic diversity is expected to meet the expectations in increased onion production.The purpose of this research was to find out radiosensitivity and the effect of various dosages of gamma on onion (Allium ascalonicum L.) growing. The research materials were two Southeast Sulawesi onion landraces namely Landrace Tomia and Landrace Buton. Gamma irradiation was conducted at the Center for Application Technology Isotope and Radiation, National Nuclear Agency, Jakarta. Onion bulbs were irradiated by 60Co gamma at dosages of 2, 4,6, and 8 Gy. It was found that the landrace Buton was more sensitive than the landrace Tomia. Gamma irradiation increases plant height, number of leaves mutant landace Tomida except dose 8 Gy and increases number of tillers at all doses of gamma irradiation. Gamma irradiation increases plant height, number of leaves and number of tillers at all treatment doses. All of the observed variables underwent increases after the gamma irradiation except for a dose of 8 Gy on Landrace Tomia. Based on the observed data, the results of this research showed: (1) the Buton was more sensitive than the Tomia; (2) the dosages of irradiation affect the sensitivity of the plant.

Abstract

This research motivated by the Fusarium oxysporum which is a soil borne fungus that can infect cultivated plants. F. oxysporum is a facultative parasite that is part of its life as a saprophyte and becomes a parasite if there is a host plant. This study aims to determine the potential of endophytic bacteria from wild plants as biological agents control of F. oxysporum in-vitro. This research was conducted at the Laboratory of Plant Protection, Phytophatology Unit, Faculty of Agriculture, Halu Oleo University from September 2020 to March 2021. The results showed that endophytic bacteria isolated from wild plants such as as Jamaica cherry/kersen (Muntingia calabura), Suruhan (Paperomia pellucida), and Markisa Hutan/Rambusa (Passiflora foetida) have the potential as biological agents to control F. oxysporum in vitro, with the two best isolates, namely ASR-7(3) and BK-3(2) which were to inhibit the growth of F. oxysporum through the mechanism of antibiosis and competition, produced enzyme bioactive compounds (amylase and protease) which degrade of pathogenic fungi, and are able to produce volatile compounds.

Abstract

Rice is the main food crop in Indonesia, and plant health greatly affects production. Farmers in Lebo Jaya Village, Konda Subdistrict, South Konawe Regency, still use traditional cultivation techniques such as scattered planting systems and minimal liming and intensive fertilization, resulting in low levels of rice plant health. Digital image processing technology offers a more efficient and accurate alternative in diagnosing plant health compared to traditional methods. This study aims to evaluate the differences in the health level of paddy rice plants using different planting systems and cultivation technology inputs in Lebo Jaya Village based on digital image processing. The methods used include field surveys, recording, and image processing of rice plants of the Inpari 32, Ciliwung, and Inpari 33 varieties managed by farmers and HKTI-Sultra (Association of Indonesian Farmers Harmony-Southeast Sulawesi). The results showed that rice plants managed by HKTI-Sultra with a more advanced planting system and cultivation technology inputs had a higher level of health compared to rice plants managed by local farmers. Digital image processing technology proved effective in detecting and evaluating the health of rice plants based on differences in cultivation systems.

Abstract

Chili is one of the important vegetables that are cultivated commercially in tropical countries with various benefits. One of the important diseases of chili plants is jaundice caused by Begomovirus or gemini virus. The disease is transmitted through a whitefly (Bemisia tabaci). The research aims to evaluate the ability and number of whitefly insects that can transmit the gemini virus to chili plants. The research was carried out using a group random design (RAK), 4 treatments each treatment was repeated 5 times. The treatment consisted of no inoculation of whitefly on plants (S0), inoculation of 1 whitefly/plant (S1), inoculation of 3 whitefly/plant (S2) and inoculation of 5 whitefly/plant (S3). The variables observed were vegetative growth, incidence and severity of disease. The presence of the whitefly (B. tabaci) increases the incidence and severity of jaundice and inhibits growth in cayenne pepper plants (C. annuum). The transmission of the gemini virus is faster with the inoculation of 5 ticks/plant with the highest incidence and severity of the disease.

Abstract

Pest is one of the constraints causing the decrease in the productivity of plants. One of the pests known as the most potential in causing the lost of cashew nut yield is Sanurus indecora. Generally, pest control still relies on the use of pesticides, while the other control methods such as biological control have not been applied optimally. The research of isolation, the effect of media and the use of Synnematium sp. to control S. indecora had been carried out from July to November, 2010. The objectives of this research were to know the pathogenic fungi infecting S. indecora in the field and the suitable media for their mass rearing, and to know the pathogenicity of Synnematium sp. on S. indecora. Test of the effects of media on the growth of Synnematium sp. consisted of five treatments and five replicates. Five kinds of media as treatment i.e: (1) PDA; (2) rice; (3) corn; (4) rice straw and (5) sago were arranged in complete randomized design. Test of the effects of spore concentrations of Synnematium sp. on mortality of S. indecora was conducted by using complete randomized design with five treatments and five replicates. Five concentrations of suspension as treatments were: control; 0.025 gml-1; 0.05 gml-1; 0.1 gml-1 and 0.2 gml-1. The results showed that the pathogenic fungus isolated from field infected S. indecora was Synnematium sp. The second experiment showed that the growth medium containing Rice Straw gave the best growth of Synnematium sp. colonies among the other treatments and 0.1 gml-1 of Synnematium sp. mycelium resulted in the highest mortality of S. indecora (57,5%) at 5 days after application. Key word: Cashew, Sanurus indecora, Synnematium sp.
