Turkish Journal of Agriculture and Forestry
In this study, the potential antihyperlipidemic, antidiabetic, and antiobesity effects of extracts obtained via infusion techniques from Artemisia absinthium L., Achillea millefolium L., Calendula officinalis L., Fumaria officinalis L., Mentha piperita L., Origanum onites L., and Urtica dioica L. grown with organic farming techniques were investigated using enzyme inhibition methods (α-glucosidase, pancreatic cholesterol esterase, pancreatic lipase, and α-amylase). It is important that natural compounds or extracts to be used in the treatment of metabolic problems have antioxidant effects. The antioxidant effects of these species were tested in terms of ABTS and DPPH radical scavenging activity, ferric reducing power, and metal …

Chemical Composition And Morphometric Traits And Yield Ofcarrots Grown In Organic And Integrated Farming Systems, Natasa Sink, Maja Mikulic Petkovsek, Robert Veberic, Nina Kacjan Marsic
Turkish Journal of Agriculture and Forestry
Changes in chemical composition and quality traits of carrot roots (Daucus carota L.) grown in organic (ORG) and integrated (INT) farming systems were investigated during two successive years. Three carrot cultivars (Fanal, Rodelika, and Rolanka) were included. Determinations of sugars, organic acids, α- and ß-carotene, and vitamin C were performed with an HPLC system, and a liquid chromatography-mass spectrometry (LC-MS) system was used for the identification and quantification of phenolics. A higher yield of carrot in the ORG system was observed (42-44 t ha-1) as compared with the INT system (37-40 t ha-1). The impact of farming system on morphometric …

Using Plant Extracts To Reduce Asexual Reproduction Of Apple Scab (Venturia Inaequalis), János Bálint, Szilveszter Nagy, Rezso Thiesz, Imre-István Nyárádi, Adalbert Balog
Turkish Journal of Agriculture and Forestry
The aim our research was to develop effective methods for organic apple farming, based on the use of plant extracts to control the asexual reproduction of Venturia inaequalis. Plant extracts of artemisinin, chelidonine, thymol, and populin tested in vitro under laboratory conditions significantly slowed down the germination of V. inaequalis conidia. During a 2-year study under field conditions, the effect of 1% populin, an extract from black poplar buds, on apple scab was tested in parallel with synthetic fungicides and a no-pesticide regime on Golden Delicious and Jonathan apples. Populin significantly reduced the number of scabbed leaves and fruits on …
Integrated Effect Of Different N-Fertilizer Rates And Bioslurry Application On Growth And N-Use Efficiency Of Okra (Hibiscus Esculentus L.), Muhammad Shahbaz, Muhammad Javed Akhtar, Wazir Ahmed, Abdul Wakeel
Integrated Effect Of Different N-Fertilizer Rates And Bioslurry Application On Growth And N-Use Efficiency Of Okra (Hibiscus Esculentus L.), Muhammad Shahbaz, Muhammad Javed Akhtar, Wazir Ahmed, Abdul Wakeel
Turkish Journal of Agriculture and Forestry
Bioslurry obtained from biogas plants has the potential to reduce the use of expensive chemical fertilizers and increase yields. A field experiment was conducted to investigate the growth response and yield production of okra fertilized with various combinations of bioslurry and nitrogen fertilizer. The experiment was planned according to randomized complete block design with 3 replications. Bioslurry was analyzed for its composition and was applied at the rate of 600 kg ha^{-1} along with 50%, 75%, and 100% of the recommended dose of N fertilizer for the production of okra. Phosphorus and potassium fertilizers were added according to recommended rates …
Evaluation Of Efficiency Parameters Of Phosphorous-Solubilizing And N-Fixing Bacteria Inoculations In Wheat (Triticum Aestivum L.), Sancar Bulut
Turkish Journal of Agriculture and Forestry
Chemical fertilizers play a significant role in increasing plant production; however, they may have a negative impact on soil fertility and cause environmental degradation in cases of excessive use. In addition, the highest levels in chemical fertilizer use have already been reached, and further yield increases do not seem possible. Due to their negative impact on soils and the environment, alternatives to chemical fertilizers are needed. Today, biological alternatives are yielding promising outcomes. Biological nitrogen fixation may constitute a significant alternative in organic farming. Therefore, in the present study, the effects of single, dual, and triple combinations of phosphorus-solubilizing [Bacillus …
Organic Materials: Sources Of Nitrogen In The Organic Production Of Lettuce, Maja Manojlovic, Ranko Cabilovski, Martina Bavec
Organic Materials: Sources Of Nitrogen In The Organic Production Of Lettuce, Maja Manojlovic, Ranko Cabilovski, Martina Bavec
Turkish Journal of Agriculture and Forestry
This paper presents the results of 2 experiments: an incubation experiment and a subsequent field experiment. An incubation experiment was set up in order to determine the mineralization potential of different organic materials (OMs) (well-rotted farmyard manure [FTM], guano [G], soybean seed [S], and forage pea seed [P]), the kinetics of mineral nitrogen (N) release, and the correlation between OM content and the quantity of mineralized N. The results of the incubation experiment were checked under field conditions in which different OMs were used as N sources for lettuce (Lactuca sativa L.). The highest mineralization rate constant k (0.127 day^{-1}) …

In Vitro Studies On Some Natural Beverages As Botanical Pesticides Against Erwinia Amylovora And Curtobacterium Flaccumfaciensis Subsp. Poinsettiae, Mehmet Nuri̇ Nas
Turkish Journal of Agriculture and Forestry
Several tannin-rich beverages were tested for their antibacterial activity against 2 important phytopathogenic bacteria, Erwinia amylovora and Curtobacterium flacumfaciensis subsp. poinsettiae. Black tea (9.5, 19 and 38 g l^{-1}), green tea (9.5, 19 and 38 g l^{-1}) and tannic acid (0.2, 0.4 and 0.8 g l^{-1}) inhibited the growth of E. amylovora and C. f. subsp. poinsettiae. Coffee (8.75, 17.5 and 35 g l^{-1}) and cocoa (8.75, 17.5 and 35 g l^{-1}) did not display any inhibitory effect on the growth of bacterial cultures. The numbers of colony forming units (CFUs) of E. amylovora in the presence of black tea, …
