This paper reports a study which utilizes deep learning for automated detection of the symptoms of diseases on vine leaves. Vine fruits or grapes are very important and have existed in Syria and surrounding areas (e.g., Turkey) for many years. Quality of vine fruits is also very important in grape production as it is consumed in these areas every day. The aim of this study is to improve diseasedetection accuracy in vine leaves and to develop a system to help Syrian and Turkish farmers and agricultural engineers to maintain the quality of grape production. In this study, over 1000 images …

Analysis Of Designs Used In Monitoring Crop Growth Based On Remote Sensing Methods, Cristina Teodora Dobrota, Rahela Carpa, Anca Butiuc-Keul
Turkish Journal of Agriculture and Forestry
Choosing appropriate designs and methods for monitoring crop growth is a challenging process of major importance. Remote sensing from space and manned or unmanned airborne operations are used to measure crop reflectance and a wide variety of other agricultural parameters. While some experiments use only a few, specific methods and designs and organize the results in lists of evidence, other experiments use a wider range of techniques to create a more credible and comprehensive assessment of crop yield. Particular situations related to the available resources in terms of data collection and expertise in addition to the intended use of the …

It is known that a polymorphic population consisting of a large number of genotypes adapts more rapidly to the environment conditions. The availability of a large gene pool predetermines the success of the introduction and further breeding of new cultivars with economically valuable features. Morphometrics is a classical tool for studying the amplitude of the variability of cultivated plants and evaluating the genotypic diversity of the artificial population. The objective of this study was to evaluate the morphological parameters of Lonicera caerulea L. fruits for 26 genotypes from the population introduced in the M.M. Gryshko National Botanical Garden (Kyiv). Morphological …

In this study, biogenic amines levels of Van herby cheese (Van Otlu peynir) matured in dry-salted/filling (basma) and brine (salamura)-salted techniques were investigated. For this purpose, a total of 100 herby cheese samples matured by dry-salted and brine-salted techniques (50 dry-salted and 50 brine-salted) were purchased from the grocery stores in Van province, and chemical characteristics and biogenic amines contents of the samples were determined. The mean chemical composition for Van herby cheese matured by dry-salted method and brine-salted methods were, respectively, as follows: pH value 4.62 and 5.16, acidity 1.50% and 1.08%, salt content 7.85% and 7.15%, dry matter …

Determination Of The In Vitro Bioaccessibility Of Phenolic Compounds And Antioxidant Capacity Of Juniper Berry (Juniperus Drupacea Labill.) Pekmez, Kübra Özkan, Ayşe Karadağ, Osman Sağdiç
Turkish Journal of Agriculture and Forestry
In this study, the total phenolic content (TPC), total flavonoid content (TFC), in vitro antioxidant capacity and individual phenolic compounds of Juniperus drupacea Labill berry and pekmez (molasses) were determined. Since pekmez was the only edible form of berry, the bioaccessibility of phenolic compounds and the antioxidant capacity of the pekmez were assessed following exposure to simulated gastrointestinal conditions. The phenolic compounds determined in the berry and pekmez were similar, while the pekmez was especially rich in protocatechuic acid, and additionally, the berries were rich catechin and chrysin. Generally, through oral to the intestinal stage of the simulated gastric conditions, …

Growth And Nutrient Responses Of Betula Platyphylla, Larix Kaempferi, And Chamaecyparis Obtusa To Different Application Methods Of Solid Compound Fertilizer, Jeong Min Seo, Huong Thi Thuy Dao, Byung Bae Park
Turkish Journal of Agriculture and Forestry
We investigated the effects of different placement methods of applying slow-release fertilizer on the growth and foliar nutrients of three contrasting tree species (i.e., fast-growing Betula platyphylla and Larix kaempferi and slow-growing Chamaecyparis obtusa) to provide implications for increasing their growth and survival in marginal forest lands. We applied 84 g pot-1 of solid compound fertilizer (SCF) at different positions: no fertilization (CON), subsurface placement (SCFs), and bottom placement [35-cm depth (SCFb)] in a greenhouse condition. Results revealed that the height and RCD (root collar diameter) of the three species had the highest growth under SCFs. Total biomass across SCFs, …
Effects Of Biological Metabolism Of Metasequoia Glyptostroboides On Nutrient Elementcontent And Enzyme Activity In Seedling Soil, Cuiyue Dong
Turkish Journal of Agriculture and Forestry
Soil has high spatial variability. Under the change of water level, soil nutrient element content and enzyme activity do not show regular changes. Therefore, the effects of biological metabolism on soil nutrient element content and enzyme activity in the adult stage of Metasequoia glyptostroboides were proposed. The characteristics of the soil were extracted, the irreversibility, accumulation, concealment and refractory rationality of the nutrient element content in the soil were expounded. According to the soil characteristics, the relationship between the nutrient element content and enzyme activity in the soil was analysed. The pH value, organic matter, lead and manganese contents of …

Developing New Hyperspectral Vegetation Indexes Sensitive To Yield Andevapotranspiration Of Dry Beans, Eyüp Seli̇m Köksal, Cengi̇z Erdem, Mehmet Taşan, Kadi̇r Ersi̇n Temi̇zel
Turkish Journal of Agriculture and Forestry
Dry bean (phaseolus vulgaris L.) field experiment was carried out under the subhumid climatic conditions of Bafra, Turkey, to evaluate the possibilities of using hyperspectral reflectance data for estimating yield and water consumption. Three irrigation management treatments that depend on monitoring soil water content and one rain-fed treatment were subjected to dry beans arranged in a randomized complete block design with three replications. In addition to soil water measurements, hyperspectral reflectance observations were made throughout the dry beans? growing season. Actual crop evapotranspiration values were calculated by using a detailed soil water balance approach. After smoothing the hyperspectral reflectance data, …

Approximately 30% of plant species of Turkey, which is among the richest countries in terms of biodiversity, has been endemic. Wild rhubarb (Rheum ribes L.) is a wild vegetable grows especially in the eastern region of Turkey and is an endemic species. In this study, genetic relationships among 80 wild rhubarb genotypes collected from some regions of Lake Van Basin, which are in the distribution area, were tried to be determined by iPBS marker system. At the same time, a commercial variety of R. rhabarbarum, which is a cultivated species, was used as control. PCR studies were conducted with 23 …

Tomato leaf miner is an aggressive and invasive pest that causes serious damage in tomato production, resulting in up to 100% yield losses during serious outbreaks. The management of tomato leaf miner with synthetic pesticides is difficult due to its leaf mining habit, short life span, high reproductive rates, and insecticide resistance problem. In this study, sequences of the mitochondrial cytochrome oxidase I (mtCOI) gene of Tuta absoluta specimens were analyzed and compared with the available COI sequence data members from GenBank. All the specimens of tomato leaf miner were clustered together in a single group with a high support …

Functional Fingerprinting Estimates Renewal Opportunities For Tree Species In A Mixed Turkey Oak Forest, Éva Salamon Albert, Ágnes Csiszár, Dénes Bartha
Turkish Journal of Agriculture and Forestry
Maintaining and managing trees with different ecological plasticity under climate conditions aggravated by short-term variability are major challenges for foresters. Our aims were to investigate species-specific ecophysiological responses of canopy trees in a mixed Turkey oak forest during their early-phase regeneration. We measured plant carbon and water exchange with portable IRGA equipment under natural field conditions (canopy gap) and in a climate-controlled (standardized) environment. We analyzed variability and differences in plant gas exchange in relation to important abiotic site parameters and the species. Assimilation, stomatal conductance, and intrinsic water use were applied as calibrating parameters for plant functional fingerprinting to …
