Abstract

Tomato (Solanum lycopersicum L.) is a vegetable commodity whose market demand continues to increase from year to year, so it requires good cultivation management so that the quantity and quality of tomatoes also continues to increase. One of the reasons for the less than optimal production of tomatoes is caused by the fungus Fusarium spp. This study aims to determine the Effectiveness of Soursop Leaf Powder Application with Various Doses of Bokashi Against Fusarium Wilt Disease in Tomato (Solanum lycopersicum L.). This research was conducted at the Plant Protection Laboratory of the Phytopathology and Land Unit I (one) Faculty of Agriculture, Halu Oleo University, Kendari from October 2022 to January 2023 using a Completely Randomized Design (CRD) Factorial 2 Factors. The first factor was soursop leaf powder (T) consisting of control (T0), 50 g soursop leaf powder (T1), 75 g soursop leaf powder (T2). The second factor was bokashi fertilizer consisting of control (B0), 500 g bokashi fertilizer (B1) and 500 g bokashi fertilizer (B2). Thus, 9 treatments were obtained, and each treatment was repeated 3 times to obtain 27 experimental units. The variables observed were the incubation period, disease severity, AUDPC and disease suppression index. The best disease severity interaction was found in the T2B2 treatment with an average disease severity of 33.33%. The effect of the interaction application treatment had a very significant effect on the treatment of soursop leaf flour and bokashi fertilizer with an average incubation period of 63.33% HSI

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

Analysis of land suitability and economic feasibility is a way that can be done to plan the development of food crops on rocky land. The research was carried out in Gu District, Central Buton Regency and soil analysis was carried out at the Integrated Laboratory of Halu Oleo University. The research method is a free survey method, land observation type is through drilling and socio-economic data is collected through filling out questionnaires and interviews with farmers. Land suitability analysis is carried out in actual conditions and land suitability after improvements have been made. The assessment is carried out by matching land characteristics with plant growth requirements. The economic parameter used to assess the feasibility of farming annual crops is the ratio of revenue to total production costs Revenue Cost Ratio (R/C). The results of the research show that the development of food crops is based on an analysis of land suitability and financial feasibility, namely the very suitable and very feasible category reaching 485.68 Ha, quite suitable and quite feasible reaching 3,568.69 Ha and not suitable and not feasible reaching 2,305.88 Ha. Directions for planting field rice, corn or soybeans by applying liming technology, applying organic material, nitrogen and phosphorus fertilization, making terraces and planting in the direction of the contour.

Abstract

The increasing need for red ginger as a raw material for medicines is a challenge for the farmers, but unfortunately ginger production is still lower than local and export demand. Basically, low soil fertility is a major obstacles in improving the productivity of ginger plants. This study aims to evaluate the changes of several soil chemical properties and the growth of red ginger plants treated with banana peel compost. This research was carried out at the Experimental Farm at the Faculty of Agriculture, Halu Oleo University from August to October 2021. This study used a randomized block design comprised of 4 treatments, namely K0 = no compost, K1 = 10 t ha-1 (400 g polybag-1), K2 = 20 t ha-1 (800 g polybag-1), K3 = 30 t ha-1 (1,200 g polybag-1) and repeated 4 times. The results revealed that the application of banana peel compost improved soil quality by increasing soil pH, organic C, CEC and total soil K. The improvements of soil properties were linear until the application of banana peel compost at 40 t ha-1. The application of banana peel compost has a significant effect on plant height and number of leaves and the impact was linear up to application of 30 t ha-1 (K3).

Abstract

This study aims to investigate the effect of combining Kinetin and IAA on the growth of kepok banana shoots in vitro. The research was conducted at the In Vitro Laboratory, Agrotechnology Unit, Faculty of Agriculture, Halu Oleo University, from January to April 2023. The study utilized a Completely Randomized Design (CRD) with six treatments: P1 = (Kinetin 1 mg L⁻¹ + IAA 2 mg L⁻¹), P2 = (Kinetin 3 mg L⁻¹ + IAA 4 mg L⁻¹), P3 = (Kinetin 5 mg L⁻¹ + IAA 6 mg L⁻¹), P4 = (Kinetin 2 mg L⁻¹ + IAA 1 mg L⁻¹), P5 = (Kinetin 4 mg L⁻¹ + IAA 3 mg L⁻¹), and P6 = (Kinetin 6 mg L⁻¹ + IAA 5 mg L⁻¹). Each treatment had five replicates, resulting in 30 experimental units, with four Kepok banana shoot explants per culture bottle. The observed variables included shoot emergence time, number of shoots, shoot length, and shoot growth percentage. Results indicated that the combination of Kinetin and IAA concentrations significantly affected the number of shoots and shoot emergence time and shoot length, but did not significantly affect the shoot growth percentage. The best treatment was P2 = (Kinetin 3 mg L⁻¹ + IAA 4 mg L⁻¹) for in vitro growth of Kepok banana shoots.

Abstract

This research is motivated by the fact that eggplant production is still low because it is triggered by the condition of agricultural land which is less fertile and the limited availability of nutrients. One alternative used to overcome this is liquid organic fertilizer (LOF) from rice washing water. This research aims to determine the effect of LOF made from rice washing water on the growth of eggplant plants and to determine the treatment that has the best effect on the growth of eggplant plants. This research was carried out at the Experimental Garden Field Laboratory II and the Agrotechnology Laboratory, Agronomy Unit, Faculty of Agriculture, Halu Oloe University (HOU) Kendari, Southeast Sulawesi from August to October 2023. The design used was a randomized block design (RBD) with LOF treatment of washing water rice consisting of three levels, namely 150 mL (B1), 300 mL (B2) and 450 mL L-1 water (B3). The variables observed were stem diameter, number of leaves, leaf area, number of branches, flowering age, total dry weight and root shoot ratio (RSR). Data from observations were analyzed using variance analysis (ANOVA) and further testing using Duncan's multiple range test (DMRT) at a confidence level of 95%. The results showed that LOF treatment of rice washing water had a very significant effect on stem diameter at 56 DAP; number of leaves and total leaf area at 14, 28, 42 and 56 DAP; number of branches, and total dry weight. The best treatment to increase the growth of eggplant plants is LOF at a dose of 450 mL L-1 water.
