Abstract

The aim of this study was to determine the effect of giving VAM (mycorrhizal arbuscular vesicular) and chitosan on the growth and yield of kencur plants (Kaempferia galanga L.). The research design used factorial randomized block design (RBD) with two treatment factors. The first factor included VAM dose consisting of (V0: 0 g/plant, V1: 10 g/plant, V2: 20 g/plant, V3: 30 g/plant) and the second factor was the dose of chitosan consisting of (C0: control, C1: immersion dose of 25 ml/L, C2: immersion dose of 25 ml/L + follow-up spraying, C3: immersion dose of 50 ml/L, C4: immersion dose of 50 ml/L + follow-up spraying). The results showed the treatment of VAM (mycorrhizal arbuscular vesicular) and chitosan gave an interaction for all observation parameters however the disease incidence component (%) had no significant effect. The best results found in the combination treatment dose of VAM 30 g/tan and Chitosan soaking dose of 50 ml/L (C3V3) with the highest average value on the number of leaves, namely 30.3 leaves, the number of tillers, namely 32.7 tillers, leaf area at the age of 5 BST that is 521.4 cm2and increased to 666.0 cm2 at the age of 6 BST, the fresh weight of the stover was 239.5 g and the dry weight of the stover was 38.6 g, the fresh weight of the rhizomes reached 85.8 g and the dry weight of the rhizomes was 34.6 g, and the production yielded a value of 10,292 tons ha1. The application of mycorrhiza on kencur plants is able to suppress pathogen infection with an average disease incidence ranging from 0-0.6%.

Abstract

The purpose of this study was to determine the effect of spraying the insecticide fipronil on the growth and intensity of pest attacks on green bean plants. This study used a randomized block design with four replications. The treatments tested in this study used application of the insecticide fipronil with a concentration of 2 ml/l in the vegetative and generative growth phases, the application of insecticides on vegetative growth only, the application of insecticides on generative growth only, and control without insecticide treatment.  The results showed that the insecticide fipronil used on vegetative and generative phases was used once and two times a week could reduce the intensity of leaf pests (24.98%) and pod pests (4.50%). Fipronil insecticide can also act in a plant growth substance as shown in the parameters of plant height, the number of leaves and components of mung bean seed yield is better than the control without fipronil application the application of insecticides on vegetative growth. The application of insecticides on the vegetative and generative growth phase by spraying insecticide once a week also affected yield components of 400.31g/clump and seed weight per mung bean plant of 27.67g/clump compared to other treatments.

Abstract

Low productivity of cayenne pepper (Capsicum frutescens L.) is often caused by high disease incidence. The application of biological agents like mycorrhizae and chitosan offers a promising strategy for sustainable intensification. This study aimed to evaluate the synergistic effects of mycorrhizae and chitosan on the growth, yield, and disease resistance of cayenne pepper var. Bara. A field experiment was conducted from April to July 2023 in Batu, Indonesia, using a factorial Randomized Complete Block Design (RCBD). The first factor was mycorrhizal dosage (M: 0, 5, and 10 g/plant ), and the second was chitosan concentration (C: 0, 4, 8, and 12 mL/L). Results showed a significant interaction (P 0.05) between mycorrhizae and chitosan on most vegetative and generative parameters. The treatment M2C3 (10 g/plant mycorrhizae + 12 mL/L chitosan) yielded the best performance, producing 8.03 t ha⁻¹, a 204% increase compared to the control (2.64 t ha⁻¹). This combination also significantly enhanced plant height, leaf count, and biomass. While no statistical interaction was found for disease incidence, both agents individually reduced disease severity. This study demonstrates a strong synergistic effect between soil-applied mycorrhizae and foliar-applied chitosan, highlighting its potential for significantly boosting cayenne pepper production.

Abstract

Coleoptera play a crucial role in maintaining the balance of agroecosystems through decomposition, nutrient cycling, and biological control. This study aimed to examine the effects of nitrogen (N) fertilizer and rice husk biochar on Coleoptera population abundance in a sorghum (Sorghum bicolor L.) plantation. Conducted at UNITRI Science Technopark, the experiment used a Randomized Complete Block Design with eight treatment combinations of N fertilizer (0, 100, 150, 200 kg/ha) and biochar (5 tons/ha), replicated three times. Coleoptera specimens were collected using pitfall traps and analyzed with ANOVA and DMRT. Results demonstrated that N fertilizer variation had no significant effect (p0.05) on Coleoptera abundance, while biochar application consistently and significantly increased individual counts (p0.05). From 1,533 identified individuals belonging to 11 morphospecies, the distribution was nearly balanced between natural enemies (777 individuals) and other insects. Biochar enhanced soil insect abundance by improving habitat quality, indicating its positive role in supporting Coleoptera populations and its potential as a key component of biodiversity conservation-based sustainable soil management.
