Öğe Adana ili ayçiçeği (Helianthus annuus L.) ekim alanlarında bulunan yabancı otların yaygınlık ve yoğunluklarının belirlenmesi(Hatay Mustafa Kemal Üniversitesi, 2019) Özkil, Mine; Torun, Hilmi; Eymirli, Serdar; Üremiş, İlhan; Tursun, NihatAmaç: Bu çalışmada Adana’nın Yüreğir, Aladağ, Ceyhan, İmamoğlu, Yumurtalık, Karaisalı, Kozan, Sarıçam, Seyhan, Çukurova ilçelerindeki ayçiçeği alanlarındaki önemli yabancı ot türlerinin yaygınlık ve yoğunluklarının belirlenmesi araştırılmıştır. Yöntem ve Bulgular: Ayçiçeği tarlalarındaki yabancı otların yoğunlukları (adet/m2 ), rastlama sıklıkları (%), özel kaplama alanları (%) ve genel kaplama alanları (%) bulunmuştur. Surveyler 2017 yılında iki farklı ayçiçeği gelişim döneminde (4-8 yaprak ve çiçeklenme dönemi) gerçekleştirilmiştir. Survey çıkışlarının tamamında en yüksek rastlama sıklığına sahip yabancı otlar olarak; Convolvulus arvensis, Chenopodium album ve Sinapis arvensis saptanmıştır. İlk survey döneminde yabancı ot yoğunlukları incelendiğinde C. album (6.76 adet/m2 ) en önemli tür olup, bunu Heliotropium europaeum (3.75 adet/m2 ) ve C. arvensis (3.05 adet/m2 ) takip etmiştir. İkinci survey döneminde ise C. album (5.13 adet/m2 ), C. vulvaria (2.42 adet/m2 ) ve Cyperus rotundus (1.98 adet/m2 ) ilk üç sırada yer almıştır. Genel kaplama alanlarında C. arvensis (% 6.89) ve C. album (% 13.57)’un en yaygın türler olduğu tespit edilmiştir. Özel kaplama alanlarına göre en önemli yabancı ot türleri; ilk surveyde S. arvensis (% 24.62), ikinci surveyde ise Cuscuta campestris (% 56.95) olmuştur. Genel Yorum: Survey çıkışlarının tamamında en yüksek rastlama sıklığına sahip yabancı otlar olarak; Convolvulus arvensis, Chenopodium album ve Sinapis arvensis saptanmıştır. Yabancı ot yoğunluğu olarak ise, ilk survey döneminde en yüksek yoğunluk değerine sırasıyla C. album, Heliotropium europaeum ve C. arvensis türlerinin sahip olduğu belirlenirken, ikinci survey döneminde sırasıyla C. album, C. vulvaria ve Cyperus rotundus türlerinin sahip olduğu belirlenmiştir. Çalışmanın Önemi ve Etkisi: Araştırma sonucunda belirlenen yabancı ot türleri ile mücadele imkanlarının araştırılması sağlanarak tarımın sürdürülebilirliğine yarar sağlayacağı düşünülmektedir.Öğe Akdeniz Bölgesi tarım alanlarında bulunan akşam sefası (Ipomoea spp.) İle tarla sarmaşığı (Convolvulus spp.) türlerinin, yaygınlık Ve yoğunluk durumları(Ege Üniversitesi, 2020) Özkil, Mine; Üremiş, İlhanAmaç: Ipomoea spp. ve Convolvulus spp. Convolvulaceae familyasına ait bitkilerden olup, tek veya çok yıllık olarak dünyada yaygın olarak bulunan istilacı yabancı otlardandır. Pek çok kültür bitkisinde sorun olan ve günümüzde istilacı özelliği ile ön plana çıkan Ipomoea ve Convolvulus türlerinin, yaygınlık ve yoğunluklarının belirlenmesi amacıyla Akdeniz bölgesinde sürvey çalışması yapılmıştır. Materyal ve Metot: Akdeniz bölgesinde bulunan Antalya, Adana, Mersin, Hatay, Kahramanmaraş ve Osmaniye illerinde yapılan sürveylerde, her bir il merkezi başlangıç kabul edilmiştir. Sürveyler sırasında her 10 km’de bir rastlantısal olarak durulmuştur. Her bir örnekleme noktasına 1m2 ’lik çerçeveden tesadüfi olarak 5 kez atılarak yabancı ot türlerinin sayımları yapılmıştır. Bulgular: Akdeniz bölgesi genelinde Convolvulaceae familyasından Convolvulus cinsine ait 5 ve Ipomoea cinsine ait 3 olmak üzere 8 yabancı ot türü belirlenmiştir. Bunların türleri, yaygınlık (%) ve yoğunlukları (adet/m2 ), sırasıyla, Convolvulus arvensis L. (52.32 ve 0.57), Convolvulus scammonia L. (0.86 ve >0.01), Convolvulus stachydifolius Coisy (0.69 ve 0.01), Convolvulus betonicifolius Mill. (0.52 ve >0.01),Convolvulus galaticus Roston. ex Choisy (0.17 ve >0.01), Ipomoea triloba L. (9.12 ve 0.13), Ipomoea hederacea (Linn) Jacq. (3.44 ve 0.02) ve Ipomoea purpurea (L.) Roth. (1.20 ve 0.01)’dır. Sonuç: Akdeniz bölgesi genelinde Convolvulus arvensis ve Ipomoea triloba yaygınlık ve yoğunluğu en yüksek olan türler olarak tespit edilmiştir.Öğe Determination of the control methods of Ipomoea triloba L. (three lobe morning glory) in cotton field(2021) Üremiş, İlhan; Özkil, MineCotton (Gossypium hirsutum L.) is used as the raw material in more than fifty industries and is also the main source of raw materials used in the textile, the oil, the animal feed, and the paper industries. Additionally, it is a crop of great economic importance for its producer countries with the added value and employment opportunities. Cotton is among the crops sensitive to weed competition and its yield decreases with the weeds. For this reason, weed control treatments should be employed effectively to obtain high yields in cotton fields. In the recent years, Ipomoea triloba (IPOTR), which has increased in its importance in the agricultural areas of the Mediterranean Region, prevents the development of the cotton because of its invasive features and causes the harvest difficulties during by hand or machine harvest. The aim of this study is to create an effective control program against IPOTR in cotton. Field experiments were carried out in Ceyhan, Adana, Turkey in 2018 and 2019. For this purpose, impact of the treatments including Pyroxasulfone 85% (PYRS) Trifloxysulfuron sodium 75% (TRFS), Pyrithiobac-sodium 383 g/l (PYBS), Glyphosate isopropylamine salt 480 g/l (GLYI), S-metolachlor 915 g/l + Benoxacor 45 g/l + hand hoe (SMEC), inter-row rotary hoe + intra-row hand hoe (FÇEÇ) were investigated 28 day-after treatment and at the harvest during two years. It has been determined that TRFS and PYBS have an efficacy over 90%, while FÇEÇ, SMEÇ, TRFS and PYBS applications have an efficacy over 60%. Applications against IPOTR have increased the cotton lint and yield. However, crop injury was observed after GLYI application (20%).Öğe The effect of hoeing time for weed management on yield and yield criteria of sunflowers (Helianthus annuus L.)(2021) Torun, Hilmi; Özkil, Mine; Eymirli, Serdar; Üremiş, İlhan; Tursun, NihatHoeing time is important in weed management and is effective to reduce weed populations in sunflower cultivation. The study was conducted between 2018-2019 to determine the hoeing times for mechanical weed control in sunflower in Adana province of Turkey. To determine weed control time in experimental fields, weeds were allowed to germinate in natural conditions at intervals between 15 days for mechanical hoeing at the emergence of sunflower to the harvest time. The interactions between weeds and sunflower yield criteria were observed by periodic hoeing treatments. At the end of the experiments, the criteria for sunflower yield, seed yield, oil content, oil quality, head diameter, plant height, weed biomass, and coverages of hoeing time effects were determined. Combining the two-year data, it was observed that the sunflower yield and seed yield were the highest in plots of 75 and 90 days weed-free, while the lowest yield and seed yield were observed in 60, 75, and 90 days weedy. It was determined that the sunflower oil yield was higher in plots of long hoeing period time, but the oil quality did not change. It was found that sunflower height were statistically similar for each year in different hoeing period times, moreover, sunflower head diameter was not affected. In weedy plots with shorter hoeing times, higher weed biomass due to increased weed coverage was noted. As a result, it was determined that long-term hoeing in sunflower weed management increases the yield, and hoeing time is significant in sunflower weed management.Öğe Tarla sarmaşığı (Convolvulus arvensis L.) ve pembe çiçekli akşam sefası (Ipomoea triloba L.)’nın çimlenme biyolojisi üzerinde araştırmalar(Zirai Mücadele Merkez Araştırma Enstitüsü Müdürlüğü, 2019) Özkil, Mine; Üremiş, İlhanGermination biology of field bindweed (Convolvulus arvensis) and three-lobe morning glory (Ipomoea triloba) was investigated in this study. The effects of sulfuric acid (15, 30, 45, 60, 90 and 120 min), sodium hydroxide (5, 10, 20, 30 and 40 min), gibberellic acid (250, 500, 750, 1000 and 2000 ppm), microwave (10, 30, 60, 90, 120 and 150 s), hot water (10, 15, 30, 60 and 120 s), mechanical scarification and hot+cold water (5, 10 and 15 times) applications were investigated in order to break the dormancy of the seeds. According to the results, breaking dormancy studies in the applications examined C. arvensis for 90 and 120 min H2 SO4 ; for I. triloba 15, 30, 45, 60, 90 and 120 min H2 SO4 applications were found to be the best breaking dormancy application. Minimum, optimum and maximum temperatures were determined as 10, 20-30 and 40 ºC for C. arvensis; 15, 25-30 and 40 ºC for I. triloba.Öğe Weed species in banana (Musa spp.) production systems in Türkiye(Sociedade Brasileira da Ciencia das Plantas Daninha, 2023) Torun, Hilmi; Özkil, Mine; Üremiş, İlhan; Uyar, Sevgi; Uludağ, AhmetBackground: Banana (Musa spp.) cultivation, has a centaury history in open fields in Mediterranean part of Türkiye has become enlarged for three decades due to benefits of covered production. Objective: Weed species, their frequencies, distributions and reasons under current techniques and geographical attributes in banana fields and greenhouses were determined to provide data to develop strategies and systems for sustainable weed management and cultivation of banana. Methods: Weeds and their coverage and densities were determined in banana fields and greenhouses surveying 2% of banana production acreage in 2021–2022. Results: 68 different species of 25 families were recorded. The most common weed species were Cardamine occulta, Amaranthus retroflexus, Portulaca oleracea, Conyza canadensis, and Oxalis corniculata. The number of weeds, their coverage and densities in individual fields were not affected significantly by production method (open-field vs greenhouse) or banana cultivars but location. Years and field size affected the number of weed species while homogeneity and cycles affected weed coverage and density. Dominant species in greenhouses were C. occulta, Pilea microphylla, O. corniculata, Echinochloa crus-galli, Setaria verticillata, and A. retroflexus but Cyperus rotundus, S. verticillata, O. corniculata, and P. oleracea in open fields. C. occulta and Pilea microphylla were recorded first time in Türkiye. Conclusions: The most common species and dominant species in fields are mainly aliens including both neophytes and archeophytes. Greenhouses and production techniques might have effect on weed problem. There are needs for further research on banana weeds including their controls to establish better strategies and control systems in banana management. © 2023, Sociedade Brasileira da Ciencia das Plantas Daninha.
