Abstract

During the periodical surveys for plant mite in the area of the Gangetic Plain of India, a new species eriophyoid mite, Ditilomiopus trewiacolous sp. nov. of the family Ditilomiopidae is found on the lower surface of the leaves of Trewia nudiflora. Trewia nudiflora L. belonging to family Euphorbiaceae, is an important medicinal plant, grows in moist tropical and semi- evergreen forests as well as non-forest areas of India and its neighbouring countries, Bangladesh, China, and Malaysia. The plant is attacked by a tiny sap sucking parasitic mite belonging to the superfamily Eriophyoidea of subclass Acari of class Arachnida and produces severe damage to the host. This new parasitic mite species is collected and processed for microscopic study and finally described with sufficient illustrations following standard taxonomic procedure. The relationship to the host plant is also described here. A comparative study of this mite with other previously known species has been conducted. After proper taxonomic diagnosis, it is found that this parasitic mite appears as new to Science from India. New name with its etymology has been given to this mite species following the Rules of International Code of Zoological Nomenclature and also registered in Zoo-Bank account to create unique ID: LSID urn: lsid: zoobank.org:pub:3BC0363B-160B-46CE-B9DA- 20864762AD10. This study may be helpful to the plant protection departments and may provide the basis of further research including DNA barcoding and systematic evolution. This research finding may also be helpful to the students of Pharmacology and Medicinal Botany.

Abstract

Corn (Zea mays L.) is the second most important agricultural commodity in Indonesia, after rice. Corn plays an important role as a raw material for animal feed, bioenergy (biofuel), and various other industrial products. However, corn productivity is highly dependent on the availability of nutrients in the growing medium. Therefore, this study aims to evaluate the effect of various AB Mix concentrations on the biomass and chlorophyll of corn (Zea mays L.) plants in a hydroponic system. The experimental design used a simple randomized complete block design (RCBD) with one factor, namely the AB Mix concentration (1/2x, 1x, and 2x) and correlation analysis using R-Studio version 2025. At 6 WAP, differences in shoot, root, and total biomass between treatments were still significant. 2x AB Mix concentration again produced the highest biomass, namely 29.67 g. Variations in AB Mix concentration have a significant effect on biomass yield (biomass of shoots at 5-6 WAP, biomass of roots at 6 WAP, and total weight at 5-6 WAP) and chlorophyll a, b content, chlorophyll a+b ratio in corn leaves.

Abstract

This study aims to study and determine the growth response of several varieties of sugarcane (Saccharum officinarum L.) on the application of coffee grounds liquid organic fertilizer (POC). This research was conducted in Gattareng Village, Salomekko District, Bone Regency, South Sulawesi from April to July 2022. The research was arranged in the form of a two-factor factorial experiment with a randomized block design (RBD) as an environmental design. The first factor is the variety which consists of three varieties namely PS 881, PS 865 and Kidang Kencana. The second factor was the POC concentration of coffee grounds which consisted of four levels, namely without POC, 15 mL/L, 30 mL/L and 45 mL/L. The results showed that the combination of the PS 865 variety with 15 mL/L POC coffee grounds gave results on the parameters of stem diameter (18.67 mm), fresh stem weight (66.50 g), stem dry weight (33.29 g) and root volume (35.33 mL). The PS 865 variety gave the best results on the parameters of plant height (34.61 cm), number of leaves (9.50), root wet weight (23.0 g), root dry weight (6.37 g) and root length (105 g). .92 cm) sugarcane seeds. POC coffee grounds 45 mL/L gave the best results on the parameters of plant height (33.67 cm), root wet weight (22.11 g), and root dry weight (5.86 g) of sugarcane seedlings.

Abstract

The relentless pursuit of increased agricultural productivity has driven the widespread adoption of synthetic chemicals in soil management. Although these chemicals undeniably enhance crop yields, their long-term environmental impacts raise significant concerns. This study examines the implications of synthetic chemical use in agriculture, emphasizing the urgent need for sustainable practices that balance productivity with environmental preservation and move beyond monoculture systems. By evaluating actual farming practices and analyzing non-regulatory policies, we highlight the challenges that our planet faces. Our investigation revealed several compelling findings: 98.2% of farmers now rely entirely on synthetic chemicals, and 87.6% have abandoned traditional tools in favor of mechanical alternatives. Furthermore, a staggering 84.8% of farmers adopted monocropping practices, particularly cotton cultivation, over the past eight years. Senior farmers, drawing on their extensive experience, expressed reservations about the effectiveness of livestock manure under current conditions. A significant 73.56% of respondents believed that livestock contributions may not produce the expected outcomes. As we explored this issue further, we recognized the urgent need to address additional contributing factors. Protecting human health and the environment requires a fundamental shift in current assumptions and practices. Therefore, we propose strategies that balance agricultural productivity and ecological sustainability, fostering a more harmonious coexistence between humans and nature.

Abstract

Celery (Apium graveolens L.) and mint (Mentha sp.) are economically important aromatic crops. However, their propagation through seeds and vegetative methods is often inefficient due to low seed viability, inconsistent germination, contamination risks, and poor plantlet uniformity. Therefore, this study assessed the response of two plant growth regulator formulations for callus induction in both species under in vitro conditions using a descriptive analysis. Two media treatments were tested: MD1 (Murashige and Skoog (MS) + 1.2 mg L-1 2,4-D) and MD2 (MS + 0.3 mg L-1 2,4-D + 0.5 mg L-1 kinetin). Observations were conducted on days 7, 14, 21, and 35 after induction (DAI) to assess explant survival, callus formation, and morphology. MD2 medium showed a tendency toward higher explant survival and greater callus formation percentages than MD1 in both species under the observed conditions. Callus initiation occurred between 7 and 14 DAI, with MD2 producing a greater proportion of viable and actively proliferating calli, predominantly characterized by friable-to-compact textures and lighter coloration. In contrast, explants cultured on MD1 exhibited a higher incidence of tissue browning and reduced callus viability, indicating the inhibitory effects associated with high auxin concentrations. These results suggest that a balanced auxin–cytokinin combination provides a more favorable hormonal environment for early callus induction than a single high-dose auxin treatment alone. Therefore, MD2 medium is recommended as an optimal formulation for early-stage callus induction in celery and mint, with potential applications in micropropagation.

Abstract

Cashew (Anacardium occidentale L.) production in tropical and subtropical regions is under serious threat from fungal diseases, such as anthracnose (Colletotrichum gloeosporioides), powdery mildew (Oidium anacardii), vascular wilt (Fusarium oxysporum), and gummosis (Lasiodiplodia theobromae). For many years, disease management has relied heavily on synthetic fungicides, a practice that has raised environmental and public health concerns. Consequently, alternative and more sustainable disease control strategies have garnered considerable attention. Literature studies indicate that these fungi suppress diseases through several interacting mechanisms, including direct antagonism via mycoparasitism and antibiosis, as well as indirect effects associated with induced systemic resistance and plant growth promotion. Across various experimental systems, certain species, particularly Trichoderma harzianum and T. asperellum, have consistently demonstrated strong antagonistic activity against important cashew pathogens. Overall, the accumulated evidence supports the potential of Trichoderma spp. as effective, residue-free, and environmentally friendly biological control agents for improving disease management in cashew-based production systems.
