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

This research aimed to examine the relationship between soil pH, exchangeable aluminum (Al-dd), and available phosphorus (P-available) in Ultisol soil through the application of sago waste compost. The research was conducted in a greenhouse located in Wowawanggu Village, Kadia District, Kendari City. Soil analysis was performed at the Laboratorium Dasar Kimia Analitik, Haluoleo University. The study was designed based on a Completely Randomized Design (CRD) with sago waste compost treatment doses, where each treatment was repeated 3 times. The doses of sago waste compost tested consisted of three levels: 10 tons/ha (KAS1), 20 tons/ha (KAS2), and 30 tons/ha (KAS3). Soil analysis was conducted on pH, Al-dd, and P-available before and after the application of sago pulp compost. Observations after application were made in stages every 7 days with four observations. The results showed that the application of sago waste compost had a significant effect on increasing pH and P-available and decreasing Al-dd in Ultisol soil. There was a very strong relationship between pH, P-available, and Al-dd, as indicated by a correlation coefficient value of > 0.90. The best treatment was shown by KAS3, with a sago waste compost dose of 30 tons/ha.

Abstract

Cashew is a promising plant in Southeast Sulawesi due to its reasonably high economic value. This species has been cultivated for years in Southeast Sulawesi, particularly in South Konawe, Konawe, and East Kolaka, with 20 to 30-years-old average plant age. This research aimed to identify morphological variations at the vegetative stage of the cashew in three evaluated Southeast Sulawesi populations (South Konawe, Konawe, and East Kolaka). The descriptive observations were carried out on the leaf apex shape, leaf shape, leaf margin, leaf venation, the color of young and mature leaves, branching pattern, tree habit, ease of peeling bark from the twig, leaf texture, as well as leaf aroma. We indicated the morphological variations in the evaluated cashew. The variations were observed in leaf shape (obovate, oblong, and circular), leaf apex shape (pointed, rounded, and indented), leaf venation (curved up, curved down, and flat), branching pattern (intensive and extensive), tree habit (upright and open, upright and compact, spreading), ease of peeling bark from twigs (difficult and easy), leaf texture (smooth and rough), and aroma (mango-like and guava-like).

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

This research aimed to determine the effect of PolyEthylene Glycol (PEG)-6000 concentration on the viability/germination and vigor of soybean seeds. The research was carried out at the Agrotechnology Laboratory, Agronomy Unit, Faculty of Agriculture, Halu Oleo University, Kendari. This research was carried out using a completely randomized design consisting of 5 treatments of PEG-6000 solution concentration and each was repeated 3 times. Each replication consisted of 3 samples so there were 45 experimental units. The variables observed were germination capacity, vigor index, maximum growth potential, growth simultaneity, and normal dry weight of the sprouts. The results of variance analysis showed that the concentration of PEG-6000 had a very significant influence on the observed variables of germination (%), vigor index (%), maximum growth potential (%), growth simultaneity (%) and normal dry weight of sprouts (g). The highest average germination capacity and maximum growth potential were obtained when administering a 6% PEG-6000 concentration, which was significantly different from the other concentrations. Meanwhile, simultaneous growth and the highest dry weight of normal sprouts were obtained at a PEG-6000 concentration of 12%, which was significantly different from the other concentrations.
