Abstract

Tomatoes rank among the top five most globally demanded crops and serve as a key ingredient in numerous dishes. However, productivity may decline due to challenges such as diseases, pest infestations, and climate change. Therefore, automatic disease detection is essential to identify early signs of illness during the growth period. This study proposes a method for detecting tomato leaf diseases using image processing techniques. The approach involves image enhancement, feature extraction, and classification. Initially, leaf disease images were enhanced using the Contrast Adjustment technique. Subsequently, color and texture features were extracted using Color Moments and the Gray-Level Co-occurrence Matrix (GLCM), respectively. Disease detection was carried out using a Support Vector Machine (SVM). The method was tested on 50 images each for healthy leaves and four types of tomato leaf diseases: Bacterial Spot, Yellow Leaf Curl Virus, Early Blight, and Late Blight. The performance of the disease detection system was evaluated using a confusion matrix, achieving an overall accuracy, sensitivity, and specificity of 96%, 90%, and 97.5%, respectively. These results demonstrate the effectiveness of the proposed SVM-based approach for tomato leaf disease detection.

Abstract

The factors that affect the low national soybean production are the reduction of agricultural land, the dry season, and extreme temperatures due to El Niño. Agroforestry can be one of the solutions, but the environmental conditions that make soybean plant growth less suitable can make it vulnerable to pathogens causing disease, such as a bacterial pustule caused by Xanthomonas axonopodis pv. glycines. This research aimed to evaluate the field response to bacterial pustules and the yield potential of various soybean varieties in mahogany agroforestry systems under the stress of the 2023 El Niño drought. This research was carried out during the El Niño dry season, August-October 2023, in the Alas Bromo Special Purpose Forest Area, Karanganyar District, Karanganyar Regency, Central Java. The research design used in this research was a complete randomized design with the factor of soybean varieties using six varieties planted under mahogany tree stands. The observed variables were height, the number of leaves, disease incidence, disease severity, infection rate, and area under the disease progression curve (AUDPC). The result showed that two varieties resistant to bacterial pustule: Agromulyo and Denasa-2. El Niño, dry season stress, causes low yield productivity; the highest yield was just 0.6 t/ha, produced by the Argomulyo variety.

Abstract

Peatlands are fragile ecosystems, making any utilization susceptible to changes that can disrupt the balance of natural resources and the environment. Three critical aspects that play a significant role in preserving peatland ecosystems (ecological, economic, and social) must be carefully considered in peatland use. A study of biophysical data and peatland usage was conducted in Pelalawan District, Riau Province, Indonesia, followed by a quantitative analysis of sustainability using Multidimensional Scaling (MDS) with the support of modified Rapfish software, referred to as Rapid Appraisal for Peat (RapPeat). The study aimed to assess the sustainability level of various peatland land use types and identify leverage attributes for targeted interventions to improve sustainability status. The research findings suggest that the peatland areas are less sustainable across these three assessed dimensions. The ecological dimension was the most sustainable, followed by the economic and social dimensions. Rubber and oil palm plantation land use types are more sustainable than the other land use types. Improving peatland sustainability involves targeted actions on leverage attributes to facilitate more sustainable practices across all dimensions.

Abstract

Plants have a hard time in its growth and development under salt stress. Salinity stress increase the activity of antioxidants and lessen the damage that salt does, phytohormones might be a good answer. Phytohormones application has emerged as a promising strategy in modern stress management as it defends plants against various abiotic stresses. The study was planned to define whether salt primed seeds treated with plant growth regulators (PGRs) can germinate normally and which level of PGRs can better assist rice germination and seedling growth. Seeds of Malaysian rice cultivars MR263 and MR284 were presoaked with 100 mM NaCl. Salt primed seeds were then treated with 0.25, 0.5, 0.75 and 1 mM Gibberellic acid (GA3), Salicylic acid (SA) and 10, 20, 30, 40 mM Thiourea (TU) in petridishes in controlled lab conditions. The experiment was designed in factorial CRD (completely randomized design) with two factors and four replicates. The interaction between rice cultivars and treatments (PGRs) significantly affected water uptake potential, germination percentage, germination index, seedling fresh and dry weight and seed vigor index. The application of 0.25 mM GA3, 0.25 mM SA and 10 mM TU reduced the inhibitory effect of NaCl priming at germination level.

Abstract

By 2050, a projected global population of 9.7 billion will exacerbate the existing resource scarcity, demanding innovative solutions for sustainable food production. While synthetic fertilizers have boosted yields, their environmental impact—including soil and water contamination, greenhouse gas emissions, and declining response rates—is undeniable. Organic farming and the utilization of biofertilizers offer a compelling alternative. These naturally occurring microorganisms, including nitrogen-fixing bacteria and phosphorus-solubilizing bacteria, enhance soil fertility, boost crop yields, and mitigate the negative consequences of chemical fertilizers. While challenges remain regarding production, distribution, and widespread farmer adoption, the growing global demand for sustainable agriculture, coupled with ongoing research into biofertilizer optimization, paints an optimistic picture for the future of this eco-friendly technology. Indeed, the shift towards biofertilizers represents not just a solution to a pressing problem but a crucial step towards a healthier planet and more secure food supply. The findings suggest that excessive use of chemical fertilizers negatively affect agricultural ecosystems. Besides this, the use of biofertilizers offers a natural sustainable alternative solution to address the imbalance of soil nutrients.

Abstract

Numerous initiatives were carried out to enhance rice production in swampy areas, which required the implementation of suitable technology. The use of adaptive variety, soil, and water management have been reported as the main keys to agricultural culture on tidal swamps. Therefore, this study was conducted to analyze the effect of several levels of substance peat humic application on the growth and yield of rice in tidal swamps. A completely randomized design was also used with two factors and four replications between March to June 2022, in Karya Bakti, Rantau Rasau sub-district of Tanjabtim District, Jambi Province. The first factor was varieties IR-64 and Inpara-4, while the second was the use of humic substance in peat consisting of 0 g/plant, 0.04 g/plant, 0.08 g/plant, and 0.12 g/plant. The cultivation process included the planting of paddy seeds within buckets containing 10 kg of soil. The result showed that the optimal yield of rice varieties IR-64 and Inpara-4, when subjected to peat humic substance in saturated soil culture, was achieved at 0.12 g/plant. This was substantiated by the enhanced uptake of essential nutrients such as N, P, and K in the plants, resulting in superior plant biomass compared to other concentration levels.

Abstract

This research aimed to evaluate the agronomic effect of deficit sprinkler irrigation sin the cultivation of banana Cavendish Musa AAA cv. Williams in Ecuador. Four treatments were carried out with different irrigation levels: T1 (40% of ETc (evapotranspiration of the crop)), T2 (60% of ETc), T3 (80% of ETc), and T4 (100% of ETc), with a design of complete random blocks and three repetitions. The results showed that the crop exhibited better biophysical behavior when irrigated at 100% of ETc throughout the study period, with higher values in total leaves and root weight, while there were no significant differences for plant height, pseudostem diameter, and leaf emission. T1 achieved greater efficiency, managing with less volume to convert the same amount of matter in vegetative development. Finally, the cost of irrigation application during weeks 5 to 16 of the crop's age was higher in treatment T4 (100% of ETc) due to the larger volume of water used in the irrigation system. It is concluded that the use of controlled deficit irrigation helps save large amounts of water, which translates into savings for farmers and better water distribution due to the effects of climate change from the reduction of flow rates.
