Resistance of Ten Local Rice Cultivars From Central Sulawesi to Nephotettix virescens (Hemiptera: Cicadellidae)
No full textThe green leafhopper (Nephotettix virescens) is the primary vector of the tungro virus, posing a significant threat to rice productivity in Indonesia. The utilization of local cultivars with natural resistance represents a sustainable strategy to mitigate such biotic constraints. This study aims to evaluate the resistance levels of ten local rice cultivars from Central Sulawesi against N. virescens using the International Rice Research Institute (IRRI) standard evaluation. The assessment covers parameters such as incubation period, symptom severity, and disease index (DI) to classify phenotypes and recommend priority genotypes. The research was conducted from April to September 2025 at the Plant Pest and Disease Green House, Faculty of Agriculture, Tadulako University, utilizing a Randomized Block Design (RBD) with three replications. The ten cultivars tested originated from Ampana (Gondu, Masai, Kamba Bulili, and Kalendeng), Sigi (PM and Kas), and Banggai (Habo, Sampara, Dongan, and Uva Buya). Results indicated that the symptom incubation period ranged from 5 to 7 days after infection (DAI). Based on the disease index (DI) observed from 14 to 56 DAI, significant genetic response diversity was found among the cultivars. The cultivar Kamba Bulili was classified as resistant with the lowest DI value of 3.8. In contrast, the cultivars Kas (DI 7.4) and PM (DI 7.0) were categorized as susceptible. The remaining seven cultivars exhibited a rather resistant response
A Study on Mapping the Potential of Rice Production in Banggai Regency
No full textThe background of this research is the need to improve regional food security amidst conditions where land degradation, land use changes, and reduced labor can disrupt the proper exploitation of agricultural resources. This study aims to analyze the potential of rice as a food crop in Banggai Regency, Central Sulawesi, which is focusing on the harvested area, production, productivity, and production base by sub-district. Research data were collected from the Central Statistics Agency (BPS, 2024) and the Food Crops, Horticulture, and Plantation Service of Banggai Regency. The analytical approach uses descriptive statistics to describe the harvested area, production, and productivity of rice, and the Location Quotient (LQ) to determine the main production base. The results of this study indicate that West Toili District has the largest harvested area (12,035 hectares), followed by Toili (11,605 hectares) and Moilong (5,038 hectares). Toili is the largest rice-producing district (67,309 tons) with an average productivity of 5.80 tons/ha. Toili, West Toili, Moilong, and Masama are the main rice production bases with LQ values > 1.00, with other sub-districts contributing to lower distribution. Less productive sub-districts need to improve cultivation technology and irrigation networks, thereby providing production facilities. Mapping can be used as a strategic reference for local governments in developing agricultural policies to achieve sustainable food security
The Effect of Nutrition Supply Duration and KNO3 Concentration on Melon Growth and Yield
No full textThis study aimed to evaluate the effect of the interaction between the duration of AB-Mix nutrient solution application and the concentration of Potassium Nitrate (KNO3) on the growth and yield of melon plants. The decrease in the sweetness of melon fruit is often associated with the use of low potassium NPK fertilizers. KNO3 is known to play an important role in improving fruit quality, especially sweetness. This study used a split-plot design with four levels of nutrient application duration (D1, D2, D3, D4) as the main plot and three levels of KNO3 concentration (K0=control, K1=850 ppm, K2=1000 ppm) as subplots, replicated four times to produce 48 experimental units. The results showed that the treatment of nutrient solution application interval (D) significantly affected plant height at 2 and 3 WAP and the number of leaves at 2, 3, 4, and 7 WAP, and the number of female flowers. The application of KNO3 (K) fertilizer significantly affected plant height at 2, 3, and 5 WAP, as well as the level of fruit sweetness (Brix). The interaction between the two treatments showed no significant effect on growth parameters and yield. Treatment D4 (the longest watering duration) resulted in a significant increase in plant height, while D3 produced the highest number of leaves and female flowers. A concentration of 1000 ppm KNO3 (K2) alone increased fruit sweetness

Interactive Effects of Monosodium Glutamate and Paclobutrazol on Growth and Flower Induction of Dendrobium Orchid
No full textDendrobium is one of the most widely cultivated ornamental orchids in Indonesia, valued for its aesthetic appeal and commercial potential. However, its relatively slow vegetative growth and long period to reach the flowering stage often hinder efficient production. The use of plant growth regulators and biostimulants can be an effective strategy to accelerate growth and promote flowering. This study aimed to evaluate the effects of Monosodium Glutamate (MSG) and paclobutrazol (PBZ) on the growth and floral induction of Dendrobium orchids and to determine the most effective combination for optimal performance. The experiment was arranged using a Randomized Block Design (RBD) with two factors, namely four MSG dosages (0 g/L, 7.5 g/L, 10 g/L, and 12.5 g/L) and three paclobutrazol concentrations (0 ppm, 200 ppm, and 400 ppm). Each treatment combination was replicated five times. Observations were made on plant height, number of leaves, days to flower initiation, and number of flowers per spike. Results showed that the interaction between MSG and paclobutrazol significantly influenced both vegetative and flowering parameters. The combination of 7.5 g/L MSG and 200 ppm paclobutrazol resulted in the most favorable response, producing taller plants, more leaves, earlier flower initiation, and a higher number of flowers compared to other treatments. Excessive paclobutrazol concentration tended to suppress vegetative growth without further improving flowering performance. These findings indicate that applying 7.5 g/L MSG together with 200 ppm paclobutrazol can effectively promote balanced growth and enhance floral development in Dendrobium orchids, offering practical benefits for commercial orchid cultivation in tropical environments
