Publication The effects of irrigation with reclaimed wastewater on heavy metal accumulation and plant development in lettuce(Parlar Scientific Publications (P S P), 2020-01-01) Akbudak, Nuray; Biçen, Nafiz; AKBUDAK, NURAY; Biçen, Nafiz; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Bahçe Bitkileri Bölümü; AAH-5045-2021; EMR-8319-2022Due to the increasing growth of the city, agricultural land has begun to take place in and around the living areas. This situation also increases the need for irrigation water available in agriculture. This study assessed the impacts of lettuce irrigation with treated effluents, as compared to domestic water (DW) irrigation, on plant physiological structure and crop productivity. The treated effluents reused for irrigation were produced in two Municipal Wastewater Treatment Plants utilizing two discrete tertiary treatments (physical purification and biological treatment). The experiment was conducted for five months on the agriculture form by using lettuce leaf type and head type lettuce. In all plant groups (the productivity, weight, length, diameter, root fresh and dry weight, root diameter), quality characteristics (deformable and number of marketable leaves per plant, total chlorophyll) and heavy metal contents (Ni, Pb, Cd, and Co) were determined. Application of treated wastewater (TWW) increased marketable yield, the number of leaves per plant, plant height, and diameter. The highest yield of lettuce plants was obtained with the treated wastewater in head type lettuce. TWW irrigation also increased the growth parameters such as the number of leaves, fresh root weight, dry weight, and total chlorophyll. Results show a high influence of TWW in nitrate content of lettuce. Results on Ni, Pb concentrations show higher values for "Festival" (leaf type) and "Bombola" (head type) plants irrigated with TWW than DW. Cd and Co values in the plants subjected to DW and TWW were similar. The values of total leaf chlorophyll content in all plants irrigated with TWW were higher than for those irrigated with DW. Results show that heavy metal accumulation, an important criterion for the use of treated waste water in agriculture, may differ in lettuce varieties. By choosing heavy metal tolerant varieties, treated wastewater can be used for long-term in sustainable agriculture.Publication Farklı domates çeşitlerinde zararlılara karşı savunma yapıları olan trikom yoğunluğunun ve acylsugar konsantrasyonunun belirlenmesi(Bursa Uludağ Üniversitesi, 2024-02-09) Gök, Narin; Özkan, Simge; Çobanoğlu, Sultan; KUMRAL, NABİ ALPER; AKBUDAK, NURAY; GENÇER, NİMET SEMA; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Bahçe Bitkileri Bölümü; 0000-0001-9442-483X; 0000-0003-2669-5667; 0000-0001-8053-5002Ülkemizde domates yetiştiriciliği ekonomik getiri ve beslenme yönünden önem arz etmektedir. Domates yetiştiriciliğindeki önemli sorunlardan biri zararlılar (böcek ve akar) nedeniyle yüksek ürün kayıplarıdır. Günümüzde bazı domates hastalıkları ve nematot zararlılarına karşı dayanıklı domates çeşitleri ruhsatlanmasına karşın; diğer zararlılara karşı dayanıklı tescilli çeşitler henüz kaydedilmemiştir. Domateslerde, böceklerin ve akarların zararına hatta biyolojik mücadele etmenlerinin aktivitesine karşı olumsuz olan unsurlardan biri de domatesin vejatatif organlarında bulunan keseli ve kesesiz trikomlardır. Kesesiz trikomlar bu canlıların vücudunu tahrip ederek olumsuz etki yaratırken; keseli trikomların içinde bulunan acylsugar’ın bunlar üzerinde zehir veya kaçırıcı etkisi bulunmaktadır. Bundan dolayı, bu çalışmada 49 domates çeşidinde bulunan trikom yapıları ve keseli trikomlardan salgılanan acylsugar konsantrasyonları araştırılmıştır. İncelenen domates çeşitlerindeki trikomların tiplerine göre yoğunluklarının saptanması zararlılara dayanıklı çeşitlerin belirlenmesi için temel bilgi sağlarken; aynı zamanda doğal düşmanların etkinliğini sınırlaması açısından da bilgi verilmiştir. Çalışmada yaprak, sap ve dallarda tip IV ve tip VI keseli; tip III ve tip V kesesiz trikomların yoğunlukları tespit edilmiştir. Her bir vejatatif organ ayrı ayrı değerlendirildiğinde farklı trikom tiplerinin yoğunluklarının çeşitlere bağlı önemli düzeyde değişiklik gösterdiği saptanmıştır. Ward’ın minumum varyans analizi metotuna göre her tipteki trikom yoğunlukları düşük, orta ve yüksek olarak kümelenmiştir. İncelenen çeşitler arasından bazılarının hem keseli hem de kesesiz trikom açısından düşük yoğunluğa sahip olduğu belirlenmiştir. Benzer istatistiki farklılıklar, keseli trikomlarda bulunan acylsugar içerikleri açısından da ortaya konmuştur.Publication The effect of irrigation of pickling cucumber with urban wastewater on product quality and heavy metal accumulation(Springer, 2022-08-22) Akbudak, Nuray; Üstün, Gökhan Ekrem; AKBUDAK, NURAY; ÜSTÜN, GÖKHAN EKREM; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Bahçe Bitkileri Bölümü; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi/Çevre Mühendisliği Bölümü; 0000-0002-7126-6792; AAG-8439-2021; EKS-0323-2022Pickled cucumber is one of the vegetables that needs water frequently during its cultivation and is processed and evaluated, and it is consumed high all over the world. In arid and semi-arid regions, wastewater is commonly used for vegetables and forage crop irrigation. In this study, a comparative field study was carried out using untreated wastewater (U), treated wastewater (T), and tap water for control (C) irrigation for the growing of cucumber pickled plants. Plant phenological and some growth parameters, fruit quality parameters, fruit, and leaf color, photosynthetic pigments, phenolic compound, vitamin C and heavy metal (HM) contents (Cr, Ni, Cd, Pb, Cu) in different parts of the plant were defined. In addition, crop productivity was measured by the means of fruit weight and diameter, and length. The results show that plant length and yield of pickling cucumbers increased by 40.90% in U, and 4.39% in T. The plants in U applications were started to harvest 5 days ago when compared with the others. On a positive note, U led to an increase in vitamin C levels and phenolic compounds. Collectively, the data suggest that U can help add value to pickling cucumber by increasing its antioxidant activity as compared to other irrigation water sources. The accumulation in the leaves was Ni > Cr > Cu > Pb > Cd, respectively. Based on the results, this study concludes that it is possible to use wastewater for cucumber irrigation. Since the edible parts of pickling cucumber are consumed after processing, they do not pose a risk to public health. This study may provide a basis for application of using untreated wastewater in high quality cucumber production.Publication The effect of leonardite, vermicompost, farmyard manure on yield and leaf quality of garden cress (Lepidium sativum L.)(Int Soc Horticultural Science, 2019-01-01) Kalaitzis, P; Blazakis, KN; Manganaris, GA; Akbudak, N.; AKBUDAK, NURAY; Zambi, O.; Bursa Uludağ Üniversitesi/Ziraat Fakültesi.; Kalaitzis, P; Blazakis, KN; Manganaris, GAThis study was carried out under greenhouse conditions and investigates the effects of different combinations of fertilizer and soil proportion, (v/v) of leonardite (1:3, 1:4, 1:8), vermicompost (1:3, 1:4, 1:8) farmyard manure (1:3) and control (soil) application on growth and leaf quality of two cultivars of garden cress (Lepidium sativum L. 'Zeybek' and 'Bahargulu'). The garden cress was harvested on the 50th day after seeding. Yield, scapus length, (cm), leaf width (cm), leaf length (cm), chlorophyll a (mg g(-1) leaf), chlorophyll b (mg g(-1) leaf), the total chlorophyll content (mg g(-1) leaf), colour, dry weight were determined in the harvested plants. At the end of the study it was determined that garden cress seeds did not germinate in leonardit applications (1:3, 1:4). The highest yield and leaf quality was in vermicompost and farmyard applications, respectively. The increasing vermicompost rates caused an increase in colour. Furthermore, colour of farmyard manure is higher than vermicompost (1:4, 1:8).Publication Assessing the impact of irrigation with treated wastewater on qualitative and quantitative properties on urfa isot and capia pepper varieties(Parlar Scientific Publications (P S P), 2022-01-01) Zambi, Ozan; Akbudak, Nuray; AKBUDAK, NURAY; Bursa Uludağ Üniversitesi/Ziraat Fakültesi.; F-9641-2013The aim of the present study was to investigate the effect of treated wastewater, untreated wastewater, and municipal water on the quality and quantity characteristics of the bell pepper Urfa Isot (Capsicum annuum cv. Urfa Isoto) and the Capia red pepper (C. annuum L. cv. Capia). We also investigated whether various irrigation waters affect the amount of heavy metal residues. When the results of the analyses were examined for morphological, chemical, and leaf characteristics, the untreated and treated wastewater applications were found to be superior for all parameters compared to that from municipal waters. Between the two wastewaters. the untreated wastewater yielded better results than the treated wastewater. According to the results of heavy metal analyses, no residue was found in the peppers studied, which are classified as the plants from which the fruits are consumed. A hazard index value was determined to be <1. In this case, it was revealed that consumption of the peppers irrigated with the treated wastewater used in our study had no negative effects on the health of the consumer.
