Abstract

Cayenne pepper (Capsicum frutescens L.) was a plant that has high economic value. The application of phosphate fertilizers in inorganic forms is not friendly to the environment and is slowly available to plants. This research was carried out from October 2019 to January 2020 in Pancot Village, Kalisoro Village, Tawangmangu District, Karanganyar Regency with an altitude of 1200 meters above sea level and Andisol soil type. This study used a completely randomized design with two treatment factors (factorial), namely the first factor is the dose of fast soluble phosphate fertilizer namely 0 kg/ha (no SP36 fertilizer), 150 kg/ha (one application), 150 kg/ha (3 times application), 100 kg/ha (3 times application), and 50 kg/ha (3 times application). The second factor is the dose of chicken manure consisting of 2 levels, namely 0 tons/ha (no chicken manure), and 40 tons/ha. Parameters observed were plant height, flowering age, fresh weight of the plant, number of branches, and number of fruit per plant. The results showed that fast soluble phosphate fertilizer had a very significant effect on plant fresh weight and fruit number. Manure treatment has a significant effect on the parameters of plant height, fresh weight of the plant, total fruit per plant. The interaction of fast soluble phosphate fertilizer and manure had a significant effect on flowering age, fresh weight, and the number of fruits per plant. The best results were in the interaction of fast soluble phosphate fertilizer with a dose of 50 kg/ha and 40 tons/ha of manure.

Abstract

Sweet corn (Zea mays var. Saccharata, Sturt) is a horticultural crop with high economic value. Sweet corn plants are susceptible to attack by plant pest organisms, reducing production yields. Using synthetic chemical pesticides of the carbamate group can reduce the diversity of predatory insects as biological controllers. Many farmers do not know about the role of predatory insects in agriculture, so there is often a mistarget in control. This study aimed to determine the diversity of predatory insects on sweet corn. The research was conducted in Cabeyan, Sukoharjo district, using the descriptive observation method. Data collection is done directly. In this study, several types of predatory insects were found, including three species from the Araneae order, two from the Odonata, one from the Hymenoptera, one from the Diptera, and one species from the Coleoptera.

Abstract

Heavy metals rank high among the hazardous contaminants in the fresh produce of plant origin, originating from growing media and contaminated air environments. Plants absorb heavy metals depending on the availability of heavy metal ions in the soil and anthropogenic activities using agrochemicals. The entry of heavy metals into the human body through the tropic level can cause various chronic diseases; so regular monitoring of the presence of heavy metal contaminants in fresh products of plant origin is critical. Testing for heavy metal contaminants in plant tissues using an atomic absorption spectrophotometer – flame. The research results showed that the heavy metal contaminant Cd was not detected in the pre-cultivated agricultural land. In plant tissues, Pb in the pre-cultivated land was detected at 49,271 ± 0,423 mg kg–1, while Cu in the pre-cultivated land was 87,369 ± 0,867 mg kg–1, and in soybean seed tissue 12,571 ± 0,698 mg kg–1. Based on research results for Cu contaminants, show that a THQ value of 0.001 means that it does not have the potential to suffer chronic non-carcinogenic health consequences. This situation is reinforced by the THQ < RfD value means that stakeholders to be vigilant about reducing Cu contaminants on agricultural land, by consistently implementing good agricultural practices.

Abstract

Copper (Cu) is an essential micronutrient for plant growth, but at elevated concentrations it can become toxic, particularly in agricultural systems transitioning to organic practices where organic fertilizers are applied intensively. This study aimed to evaluate the bioaccumulation of Cu and physiological stress responses in chili plants (Capsicum annuum L.) cultivated under varying doses of cattle manure in a transitional organic farming system. The experiment was arranged in a completely randomized block design with manure application rates ranging from 15 to 50 tons per hectare. Observed parameters included yield, Cu concentration in the fruit, and food safety indicators such as Bioaccumulation Factor (BAF), Estimated Weekly Intake (EWI), Provisional Tolerable Weekly Intake (PTWI), and Target Hazard Quotient (THQ). The results showed that increasing manure dosage significantly enhanced fruit yield and Cu accumulation. However, no traces of cadmium (Cd) or lead (Pb) were detected, and Cu levels remained within acceptable food safety limits. The highest Cu concentration was observed at the highest manure dose, yet BAF and PTWI values indicated minimal risk to human health. These findings suggest that while cattle manure can improve crop productivity, it may also contribute to Cu accumulation that could trigger oxidative stress in plants. This research contributes to the scientific understanding of micronutrient dynamics, food safety, and plant stress physiology within sustainable organic farming systems.
