Abstract

This research aims to determine the effect of using endophytic bacteria from wild plants in the biological control of Fusarium Wilt disease on tomato plants and to find out which isolate method is best for controlling Fusarium Wilt disease on tomato plants. The research was carried out at the Plant Protection Laboratory, Phytopathology Unit, and Experimental Garden Greenhouse 1, Faculty of Agriculture, Halu Oleo University, Kendari, from September to November 2022. This research used a Randomized Block Design (RBD) with 5 treatments repeated 3 times for a total of 15 treatment units. The variables observed were divided into 2, namely vegetative plant growth (plant height, number of leaves, and number of productive branches) and the incidence of Fusarium Wilt disease on tomato plants. The data was analyzed using variance and if there was a real influence, it was continued with the Duncan Multiple Range Test (DMRT) at a confidence level of 95%. The results of the research showed that endophytic bacteria from wild plants were able to increase plant growth and control Fusarium Wilt disease in tomato plants and ASR-3(2) isolate was the best isolate in increasing plant growth and controlling Fusarium Wilt disease.

Abstract

This study aimed to determine the response of growth and yield of lettuce (Lactuca sativa L). This research was carried out at the Field Laboratory of Experimental Gardens II and the Laboratory of Agrotechnology, Faculty of Agriculture, Halu Oleo University from December 2021 to February 2022. This research was carried out using a Randomized Block Design (RBD) with a single factor consisting of five treatment levels, namely, No Organic Fertilizer Liquid (P0), Liquid Organic Fertilizer 10 ml.L-1 (P1), Liquid Organic Fertilizer 20 ml.L-1 (P2), Liquid Organic Fertilizer 30 ml.L-1 (P3), Liquid Organic Fertilizer 40 ml. L-1 (P4) and each treatment was repeated three times, each replication contained 15 plants, so the total treatment unit was 45 polybags. The variables observed were: plant height (cm), number of leaves (strands), leaf area (cm2), wet weight of plants (g), dry weight of plants (g), wet weight of plant roots (g), and dry weight of plant roots. Each observation variable was analyzed using analysis of variance to determine the effect of treatment. if there is F-count greater than F-table followed by UJBD at a 95% confidence level. The results showed that the liquid organic fertilizer treatment had an effect on the observed variables of plant roots at harvest, which showed that at (10 ml.L-1) is the best concentration by showing the highest average value of lettuce plant growth and yield

Abstract

The rain-fed rice fields of Jati Bali Village have contributed to increasing rice productivity in South Konawe Regency. This study aims to determine the status of soil fertility in rainfed paddy fields and to determine fertilization recommendations in rainfed lowland fields. This research was conducted in Jati Bali Village, West Ranomeeto District, South Konawe Regency and the Biology Laboratory of the Faculty of Mathematics and Natural Sciences, Halu Oleo University, taking place from May to July 2022. This research used a purposive sampling method based on different altitudes. Soil samples were taken, namely upper rice fields (65-71 m asl), middle rice fields (58-64 m asl) and lower rice fields (50-57 m asl) then carried out laboratory analysis on the soil samples. The results showed that the fertility status of rainfed lowland rice fields was classified as low and moderate. Low soil fertility is found in the upper paddy fields and middle paddy fields. While soil fertility is found in the lower paddy fields. Fertilizer recommendations for the upper paddy fields are 200 kg ha-1 of NPK fertilizer, 175 kg ha-1 of Urea fertilizer and 2 t ha-1 of manure. While the recommendation for fertilizer for middle and lower paddy fields is the application of NPK fertilizer as much as 150 kg ha-1, Urea fertilizer as much as 200 kg ha-1 and manure as much as 2 t ha-1.

Abstract

This study aims to determine the genetic diversity of several local cayenne pepper cultivars from Southeast Sulawesi and to find out which local cayenne pepper cultivars from Southeast Sulawesi show the best growth and yields. This research was carried out at the Agricultural Extension Center (BPP) Pilot Land located in Langkoroni Village, Maligano District, Muna Regency. The research implementation time starts from October 2021 to February 2022. Data analysis using variety fingerprints, if it shows a real and very real influence then continued Duncan multiple range test (DMRT) with the help of statistical product and service solution (SPSS) application facility and calculate genetic diversity value. The results showed that quantitative characters with high diversity were found in the characters of flowering age, harvest age, number of fruits, fruit weight, fruit length and fruit diameter. Somewhat high is found in the character of plant height and leaf area. Slightly low was found in the character of the number of leaves and low was found in the character of the length of the fruit stalk. The qualitative characters observed were uniform because there were no differences in the observed local cayenne pepper cultivars from Southeast Sulawesi. The local cayenne pepper cultivar from Southeast Sulawesi that showed the highest growth and fruit yield was found in the cultivar from Kolaka (145.96 grams/plant), followed by North Buton-2 (125.71 grams/plant), then South Konawe (121.93 grams/plant) compared to other local cayenne pepper cultivars.

Abstract

Burn disease caused by the fungus Ustilago scitaminea is an airborne pathogen whose spores can be carried by the wind, agricultural tools and people who wear the clothes they wear. The use of resistant varieties is a fairly effective control in controlling smut disease in sugarcane. This study aims to determine the resistance response of sugarcane varieties to smut disease on sugarcane (Saccharum officinarum L.). This research was conducted at the Laboratory of Plant Protection, Phytopathology Unit, Faculty of Agriculture and the Green House of the Faculty of Agriculture, University of Halu Oleo, Kendari. The research design used a completely randomized design (CRD) consisting of 4 varietal treatments namely the Kidang Kencana variety (V1), the Bululawang variety (V2), the green sugarcane cultivar (V3) and the red sugarcane cultivar (V4). The results of this study indicated that disease incidence and disease severity had no significant effect at all observation times (7, 14, 21, 28, and 35 DAP). The longest incubation period with the incidence and severity of the disease was 0% in the V1 and V2 treatments.

Abstract

Ultisol still has the potential for the development of dry land agriculture. However, the utilization of Ultisol faces soil fertility constraints which can inhibit plant growth, especially bean plants, if not managed properly. The aim of the study was to determine the effect of manure and dosage on pH, organic C, total N, and yield of chickpea plants (Phaseolus vulgaris L.). The research was conducted at Field Laboratory II, Faculty of Agriculture, Halu Oleo University, from November 2021 to January 2022. The research was arranged according to a Split Plot Design with a factorial pattern. The main plot consists of three levels, namely chicken manure (KA), goat manure (KK) and cow manure (KS). Subplots consisted of 4 levels, namely: without manure (D0), 2% manure (D1), 4% manure (D2) and 6% manure (D3). The results showed that chicken manure, goat manure and cow manure had an effect on soil pH, C-organic and N-total. The highest increase in soil pH was achieved in chicken manure treatment (6.3), followed by goat manure and the lowest in cow manure. The highest increase in C-organic occurred in the chicken manure treatment (2.07%), then goat manure and the lowest was cow manure. The highest increase in N-total occurred in the cow manure treatment (0.13%), then the chicken manure and the lowest was in the goat manure treatment. There was no significant interaction between manure and dosage on bean yields. Manure has an independent effect on the number of pods and pod weight. The highest number of pods and the heaviest weight were achieved in the KK treatment with 20.17 pods and 97.17 g weight, followed by the KA treatment with 17.00 pods and 75.75 g weight and in the KS treatment with 3.25 pods and weighs 12.17 g.
