Abstract

Predatory insects are essential in controlling pest populations; however, their ability to work depends on prey availability and quality. This study investigates the potential of alternative prey to enhance the predatory efficiency and reproductive success of Sycanus annulicornis, a generalist predator used in pest management. The research assessed predation behavior, longevity, and reproductive capacity of S. annulicornis when fed with Hermetia illucens, Tenebrio molitor, and Alphitobius diaperinus. Choice and no-choice tests revealed a significantly higher predation rate for H. illucens (98.0 ± 50.25 for females and 89.0 ±14.0 for males; P < 0.05) compared to T. molitor (67.0 ± 15.4 for females, 54.2 ± 11.2 for males) and A. diaperinus (67.0 ± 12.1 for females, 65.5 ± 17.0 for males). Longevity analysis showed that females fed H. illucens lived significantly longer (49.7 ± 1.00 days, P < 0.05) than those consuming T. molitor (41.2 ±6.46 days) or A. diaperinus (41.3 ± 8.45 days). Reproductive performance was highest for H. illucens, with fecundity (33.1 ± 22.0 eggs) and fertility (27.5 ± 18.7%) exceeding that of T. molitor (24.5 ± 13.1 eggs, 10.0 ± 4.4%) and A. diaperinus (30.3 ± 22.3 eggs, 19.0 ± 12.7%). This study supports using H. illucens as a nutritionally adequate prey for mass rearing S. annulicornis, improving its application in biological pest control.

Abstract

Zinc oxide nanoparticles (ZnO-NPs) can be used as nanofertilizers and nanogrowth regulators to enhance plant agronomic performance. Nevertheless, far too little interest has been paid to the impacts of ZnO-NPs integrated with vermicompost in horticultural crop cultivation. This study investigated the effects of ZnO-NP-enhanced vermicompost (NEV) on the growth, leaf nutrient content, yield, and quality of tomato plants. A controlled greenhouse experiment was conducted, in which tomato plants were subjected to various treatments, including application of NEV combined with various doses of ZnO-NPs via direct soil and foliar spray, compared with control, NPK fertilizer, and vermicompost. The results showed that direct soil application of NEV positively affected tomato leaf growth and NPK content. This enhanced nutrient uptake contributed to increased tomato yield. The direct soil application of NEV (ZnO 50 mg kg-1) increased the tomato fruits (315% and 183%) and the fresh weight of tomato fruits (344% and 197%) in comparison to the control and NPK fertilizer. Additionally, the study demonstrated that applying NEV not only increased yield but also increased the vitamin C content of tomatoes. The findings highlight the potential of this innovative agricultural approach as a sustainable means to enhance tomato production.

Abstract

Peatlands have the potential to support sustainable agricultural production when properly managed, particularly through the use of organic inputs. This study aimed to evaluate the effects of organic fertilizer on the growth and nitrogen, phosphorus, and potassium nutrient uptake efficiency of Dayak onion plants cultivated in inland peat soil. The research was conducted from September to December 2023 at the Experimental Garden of the Faculty of Agriculture at the University of Palangka Raya. A randomized block design was used with five levels of cow manure application: 0, 5, 10, 15, and 20 t.ha-1, each replicated four times. The application of cow manure significantly increased leaf number at 50, 60, and 70 days after planting (DAP), as well as the increase in leaf number between 40 and 50 days, root and shoot fresh weight, number of tillers, and fresh bulb weight. The 10 t.ha-1 treatment increased leaf number by 87% at 50 DAP, 74.2% at 60 DAP, and 43.8% at 70 DAP compared to the control treatment. However, it did not significantly affect plant height. The regression equation is y = −0.0081x² + 0.2226x + 2.8726, with R² = 0.99. The dose of cow manure fertilizer that produces maximum tuber fresh weight is approximately 13.75 t ha⁻¹. This dose shows the best growth response before tuber weight decreases at higher fertilization levels. These findings indicate that applying organic fertilizer, particularly at an optimal dosage, can improve the productivity of Dayak onion grown in peat soil, supporting the sustainable use of marginal land for horticultural development.

Abstract

Kale (Brassica oleracea L. var. sabellica) is a high-value horticultural crop in Indonesia that requires precise water management to enhance productivity. This study examines the effects of growing media composition and type on water use efficiency, evapotranspiration (ET), and growth performance using a Randomized Complete Block Design with ANOVA and Duncan’s Multiple Range Test (DMRT). Two factors were tested: (1) media composition (M1: soil: media mix = 1:1; M2: 3:1; M3: 1:3) and (2) media type (P1: rice husk biochar; P2: manure; P3: cocopeat). Results showed an average water consumption of 254.98 ± 131.3 ml/day and water use efficiency of 11.6 ± 4.3%. ETo, ETc fluctuated due to environmental factors. Using Blaney-Criddle, ETo averaged 6.18 mm/day with Kc of 1.8 ± 0.45, while Hargreaves yielded 12.24 mm/day with Kc of 0.9 ± 0.22. Cocopeat and a 3:1 soil-media mix yielded 162 g/plant and a potential yield of 1.8 tons per hectare. These findings highlight the importance of optimized growing media for increasing water spinach productivity in tropical greenhouse conditions and provide a quantitative integration of evapotranspiration analysis across various growing media compositions and types.

Abstract

Hiyung chilli (Capsicum frutescens) is a local cultivar grown in the lowland swamp agroecosystem of Hiyung Village, South Kalimantan, where cultivation is constrained by seasonal flooding and water fluctuation, limiting planting to once annually. This study evaluates the availability of essential macronutrients, such as nitrogen (N), phosphorus (P), and potassium (K), in floating raft-based growing media supplemented with NPK fertilizer. A descriptive method was applied using three fertilizer doses: 0, 150, and 300 kg ha⁻¹. Results show that increasing fertilizer doses proportionally enhances nutrient availability, including NH₄⁺ (189,54 ppm), NO₃⁻ (26,17 ppm), available P₂O₅ (17,57 ppm), and K (0,65 me 100 g⁻¹), accompanied by a pH increase to 5.54. Correlation analysis reveals a strong to very strong positive relationship between pH elevation and macronutrient availability, and a weak to very strong relationship between nutrient levels and plant growth. These findings support sustainable nutrient management strategies to improve Hiyung chilli productivity under swamp-based cultivation conditions.

Abstract

Soil density is a crucial parameter for soil physical health. It influences the ability of plant roots to penetrate the soil, which in turn impacts the plant's absorption of water and nutrients. The research was conducted in Jatipurno Subdistrict, Wonogiri Regency, to determine the distribution of soil density, the influence of sources of diversity, the determinants of soil density, and recommendations for land use. Descriptive exploratory research through survey and laboratory analysis was employed in this study, with soil density measured using the Dynamic Cone Penetrometer (DCP). The quite high soil density class covers 2,631.28 ha (60.51%), and the high soil density class covers 1,716.87 ha (39.49%). Land use did not significantly affect soil density, whereas soil type, slope gradient, and rainfall did. Soil density values have a significant positive correlation with bulk density (r = 0.862; P-value = 0.000; N = 45) and texture (r = 0.572; P-value = 0.000; N = 45), and have a significant negative correlation with water content (r = -0.457; P-value = 0.002; N = 45), porosity (r = -0.699; P-value = 0.000; N = 45), and organic C (r = -0.404; P-value = 0.006; N = 45). These five parameters were selected as determining factors, increasing bulk density and texture (clay content), and decreasing water content, porosity, and organic C will increase soil density. Improved land management, based on these determining factors, is needed to increase agricultural land use for sustainable agricultural production, such as mulching, increasing organic matter content, and minimal tillage to maintain soil surface moisture.

Abstract

Spodoptera frugiperda is a pest that can rapidly destroy maize plants and cause economic losses for maize farmers. The objective of this study was to analyze the incidence and severity of S. frugiperda on maize crops in Kulon Progo District. Sampling locations were determined using the random stratified method. The purposive method was used to determine the maize fields used for sampling. The W-scouting method was used to calculate the incidence and severity of S. frugiperda infestation. The collected data were analyzed using a correlation test to evaluate the relationship between the incidence and severity of S. frugiperda infestation. The analysis revealed spatial variability in infestation levels. The lowest incidence was observed in Samigaluh Sub-district, with an infestation rate of 9.13%, whereas the highest was observed in Panjatan Sub-district, with a rate of 20.95%. The degree of crop damage also differed among locations. In Lendah Sub-district, the pest caused substantial injury, with 14 corn plants categorized as severely damaged. In contrast, Temon Sub-district recorded 176 plants exhibiting only minor damage symptoms. These results indicate that S. frugiperda infestations were present throughout the surveyed region, with the highest incidence detected in Panjatan and the lowest in Samigaluh, suggesting localized differences in pest pressure and environmental suitability.

Abstract

The golden apple snail, Pomacea canaliculata, is known to be an injurious introduced species in the rice ecosystem of Southeast Asia, while the native apple snails, represented by Pila scutata, have shown declining populations over various parts of the region. Dietary differences may contribute to the contrasts in ecological damages, but information regarding comparison studies involving agricultural and aquatic plants is limited. This report considers the feeding rates of P. scutata and P. canaliculata on rice, Oryza sativa, and two other aquatic plants, Ludwigia adscendens and Pistia stratiotes, using a standardized laboratory bioassay. In this investigation, the feeding rates of individual snails of P. scutata and P. canaliculata were determined on pre-weighed plant material after starving them for 24 hours. In the bioassay, the amount of plant material eaten by the snails and the ratio of the reduced or remaining weight to the initial weight were used to determine the feeding rates. In general, the amount of plant material consumed by P. canaliculata is much higher than that eaten by P. scutata over all the plant species (Mann-Whitney U test, Holm-corrected P < 0.05). In particular, the consumption of rice seedlings by P. scutata is characteristically low.
