Turkish Journal of Agriculture and Forestry

Rice is a fundamental food source for more than half of the global population. This study evaluated the germination capacity of four rice lines [Sakh (V1), Campena (V2), Kharamana (V3), and Binicol (V5)] and one local variety, KSK-282 (V5). The findings revealed significant differences in the germination attributes among the rice lines. V1 and V3 showed superior germination performance, while V5 consistently exhibited the lowest values. The one-way analysis of variance (ANOVA) showed significant differences (p ≤ 0.05) across multiple parameters, including the coefficient of velocity of germination (CVG), germination index, mean germination rate (MGR), and synchronization index.

From Ancient Wisdom To Modern Medicine: The Cultural And Therapeutic Significance Of Ficus Carica L. (Moraceae) Extracts In Colorectal Cancer Treatment, Esra Hacimüftüoğlu, Azizeh Shadidizaji, Kağan Tolga Ci̇ni̇sli̇, Songül Karakaya

Turkish Journal of Agriculture and Forestry

Figs, mentioned in the Torah, the Bible, and the Quran, are of historical and cultural significance and have been used for medical treatment, prompting extensive research. Colorectal cancer (CRC), the second leading cause of cancer-related death worldwide, is expected to significantly increase in terms of mortality rates by 2035, with its progression closely linked to inflammatory processes. Cyclooxygenase 2 (COX-2), an enzyme encoded by the Ptgs2 gene, plays a key role in these processes by converting arachidonic acid into prostaglandin E2 (PGE2), a mediator of inflammation. In the present study, the potential of natural antiinflammatory compounds, specifically fumaric acid and …

Exploring The Impact Of Planting Density And Environmental Variables On Maize Yield Productivity, Bojan Drašković, Bojan Mitrović, Velimir Mladenov, Ivana Mitrović, Milena Janković, Miroslav Zorić, Nenad Đurić

Turkish Journal of Agriculture and Forestry

Our study investigated the performance of various maize hybrids across diverse environments and planting densities, with the aim of understanding the complex interaction between genotypes, environmental conditions, and planting practices. A set of 13 experimental maize hybrids and two commercial check hybrids was tested over a 3-year period at eight different locations and under two distinct plant densities using a split-plot design. The results revealed significant variations in grain yield (GY) among hybrids across different environments, suggesting a substantial genotype-by-environment (G × E) interaction effect, particularly of the crossover type. This variability was attributed to fluctuations in environmental factors such …

Adapting To Climate Change In Semiarid Regions Via Conservation Measures: Climate-Smart Crop Rotations Of Food Legumes In Cool Seasons, Velibor Spalevic, Mohsen Janmohammadi, Naser Sabaghnia, Shuraik Kader

Turkish Journal of Agriculture and Forestry

The high potential of evapotranspiration, unsuitable soil conditions, irregular distribution of rainfall, and ineffective techniques of soil moisture conservation are among the limitations of semiarid regions of Central and West Asia and North Africa (CWANA), and they have intensified during recent decades with climate change. CWANA’s agroecosystems are fragile and highly vulnerable to the consequences of global warming and aggravation of water scarcity, and need to redefine agroclimatic zoning. Winter cereals are the predominant crops in the region of CWANA. The highest amount of cultivation is allocated to societies with dominant rainfed agriculture, which is often not economically profitable. The …

The stepwise linear regression (SLR) method, support vector machine (SVM) regression method, and radial basis function neural network …

Postharvest Application Of 1-Methylcyclopropene And Modified Atmosphere Packaging Extends Shelf Life And Maintains Eating Quality Of Mango Fruit Cv. Sufaid Chaunsa, Hafiz Muhammad Usman, Sajid Hussain, Raheel Anwar, Ahmad Sattar Khan, Aman Ullah Malik, Muhammad Moaaz Ali, Khurram Ziaf, Arooba Abbas

Turkish Journal of Agriculture and Forestry

The mango (Mangifera indica L.) fruit is globally relished for its sweet taste, unique aromatic profile, and enriched nutritional value. However, its short postharvest life is a serious challenge for export to long-distance markets. 1-Methylcyclopropene (1-MCP) is an ethylene inhibitor known to delay ripening in many fruits, including mango. However, comparative research suggesting an appropriate method to treat mangoes with 1-MCP is limited. In this study, mango fruit cv. Sufaid Chaunsa were fumigated with 0.25 ppm 1-MCP or treated aqueously with 1.2 ppm 1-MCP for 5 min and then packed in modified atmosphere packaging (MAP). The control fruits were not …

Anisakid Nematodes In Black Sea Harbour Porpoise (Phocoena Phocoena Ssp. Relicta) From The Turkish Western Black Sea: With Notes About Association With Body Length And Stomach Content, Erdem Danyer, Işil Aytemi̇z Danyer, Arda Mehmet Tonay, Ayhan Dede, Hayretti̇n Akkaya

Turkish Journal of Veterinary & Animal Sciences

Parasites are naturally present in the natural gastrointestinal fauna of marine mammals without necessarily causing any pathology. However, under various stress conditions, parasites can cause pathological disorders in the gastrointestinal system. There is insufficient information on parasite fauna of mammals living in the Black Sea waters off the Turkish coast. This study examined the stomach contents of bycaught and stranded harbour porpoises collected between 2002 and 2003 along the Turkish coast of the western Black Sea for parasitic presence. In a previous stomach content study, 450 nematode fragments (including 232 intact specimens) were occasionally collected from 33 harbour porpoises (27 …

Effects Of Humic Acid And Salt Stress On Growth, Physiological Parameters And Mineral Substance Uptake In Artemisia Dracunculus L. (Tarragon), Serhat Seven, Şener Akinci

Turkish Journal of Botany

In this study, the physiological changes in Artemisia dracunculus L. plants under salinity stress and the remediative roles of leonardite-derived liquid humic acid (HA) were investigated. Salt stress caused a significant decrease in measured growth parameters (plant height, fresh weight of leaves and stems, dry weight of leaves and stems, number of leaves and leaf area). HA had a positive effect on growth parameters at 75 mM NaCl concentration, except for leaf number, but its effect was limited at 150 mM NaCl concentration. The total amount of protein was found to be lower in the leaves of seedlings grown under …
