Öğe Effects of Various Irrigation Regimes on Soil Water Balance, Yield, and Fruit Quality of Drip-Irrigated Peach Trees(Asce-Amer Soc Civil Engineers, 2011) Gunduz, M.; Korkmaz, N.; Asik, S.; Unal, H. B.; Avci, M.The aim of this research was to determine the amount of irrigation water, irrigation interval, and water consumption that gave the greatest yield, to determine the effect of irrigation on fruit quality characteristics, and to investigate variations in soil moisture in Redhaven peaches irrigated by drip irrigation in the Aegean region of Turkey. The study was performed in 2003 and 2004 on split plots in randomized blocks with three replications. Main treatments were 3 and 6 days between irrigations, and subtreatments comprised four different pan coefficients (K-p1.25, K-p1.00, K-p0.75, and K-p0.50). According to the 2-year averages of peach yields, the effect on yield of the amount of irrigation water was found to be significant (p < 0.01), but the effect of the irrigation interval was found not to be significant. Total yield varied between 5,966 and 16,340 kg ha(-1), and marketable yield between 5,349 and 14,164 kg ha(-1), according to irrigation treatments. A maximum average yield of 14,101 kg ha(-1) was obtained from treatment K-p1.00. Average irrigation water amount for this treatment was 482 mm, average water consumption was 705 mm, and the K-pc value was 0.785. Maximum water-use efficiency (WUE) of 2.02 kg m(-3) was obtained from K-p1.00. The yield response factor (ky) was found to be 1.2. Weight of individual fruit varied between 203 and 253 g, height varied from 6.3-6.6 cm, diameter from 7.2-7.7 cm, soluble dry matter from 10.8-14.5%, and juice pH from 4.14-4.37. In the years of the study, the declining trend of soil moisture was greater in the treatments that received little irrigation water than in those that received more. After irrigation was ended, soil moisture decreased rapidly and eventually reached the wilting point. To conclude, when setting up a drip-irrigation program for fully grown peach trees in the Aegean region, the irrigation interval may be 3 or 6 days. The amount of water to be applied at each irrigation can be determined by correcting the total evaporation from a Class-A evaporation pan over the chosen irrigation interval by a coefficient of 0.785.

B.; Asik, S.; Gunduz, M.This study determines the water delivery performance at secondary and tertiary canal level of the Menemen Left Bank Irrigation system, an open canal irrigation system located in Turkey, for the irrigation seasons of the years 2005-2007. At secondary canal level, water supply ratio was used, and at tertiary level, the indicators of adequacy, efficiency, dependability, and equity were used. In calculating these indicators in this study, the amounts of water diverted to the canals, efficiency of water conveyance, and of water application were measured. Of these indicators, the water supply ratio was determined for the secondary canal, and the other indicators were determined for a total of six selected tertiary canals at the head, middle, and lower end of the secondary. At secondary level, the water supply ratios obtained to total irrigation water requirements for the months of July and August, when requirement for irrigation water is at a maximum, was determined to be less than one, while the water supply ratios obtained to net irrigation water requirement was found to be more than one. With regard to water delivery performance at tertiary level, adequacy, efficiency, dependability, and equity were found to be poor for each of the three years of the study, with efficiency rising to "fair" level only in 2005. In order to raise the water delivery performance of the system, it is necessary to reduce water conveyance losses to increase the water application efficiency, to prepare water distribution plans which take in tertiary canals, and to measure and monitor the water diverted to the canals.Öğe Evaluation of the Water Delivery Performance of the Menemen Left Bank Irrigation System Using Variables Measured On-Site(Asce-Amer Soc Civil Engineers, 2009) Korkmaz, N.; Avci, M.; Unal, H.

S.; Cetin, B.; Yemisen, M.; Naz, H.; Gorenek, L.; Agalar, C.This study reviewed the clinical, laboratory, therapeutic and prognostic data on genitourinary involvement of brucellosis in this largest case series reported. This multicentre study pooled adult patients with genitourinary brucellar involvement from 34 centres treated between 2000 and 2013. Diagnosis of the disease was established by conventional methods. Overall 390 patients with genitourinary brucellosis (352 male, 90.2%) were pooled. In male patients, the most frequent involved site was the scrotal area (n=327, 83.8%), as epididymo-orchitis (n=204, 58%), orchitis (n=112, 31.8%) and epididymitis (n=11, 3.1%). In female patients, pyelonephritis (n=33/38, 86.8%) was significantly higher than in male patients (n=11/352, 3.1%; p<0.0001). The mean blood leukocyte count was 7530 +/- 3115/mm(3). Routine laboratory analysis revealed mild to moderate increases for erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). The mean treatment duration and length of hospital stay were significantly higher when there were additional brucellar foci (p<0.05). Surgical operations including orchiectomy and abscess drainage were performed in nine (2.3%) patients. Therapeutic failure was detected in six (1.5%), relapse occurred in four (1%), and persistent infertility related to brucellosis occurred in one patient. A localized scrotal infection in men or pyelonephritis in women in the absence of leucocytosis and with mild to moderate increases in inflammatory markers should signal the possibility of brucellar genitourinary disease.Öğe Genotype x environment interaction and stability analysis for dry matter and seed yield in field pea (Pisum sativum L.)(Spanish Natl Inst Agricultural & Food Research & Technolo, 2009) Acikgoz, E.; Ustun, A.; Gul, I.; Anlarsal, E.; Tekeli, A. S.; Nizam, I.; Avcioglu, R.; Geren, H.; Cakmakci, S.; Aydinoglu, B.; Yucel, C.; Avci, M.; Acar, Z.; Ayan, I.; Uzun, A.; Bilgili, U.; Sincik, M.; Yavuz, M.The objectives of this study were to evaluate dry matter (DM) yield and seed yield of six leafed and semi-leafless pea (Pisum sativum L.) genotypes, and to compare them for these traits. Evaluation of genotype x environment (G x E) interaction, stability and cluster analysis were also carried out at eight diverse locations with typical Mediterranean and Mediterranean-type climate during the 2001-2002 and 2002-2003 growing seasons. Significant differences were found among the pea genotypes for DM and seed yield on individual years and combined over years, and in all locations. All interactions which related to G x E interaction showed significance (P>0.001) for DM and seed yield. The highest yield (4789 kg ha(-1)) was obtained from the leafed genotype 'Urunlu'. However, stability analysis indicated that for DM yield, the leafed genotypes 'Golyazi' and 'Urunlu' should be grown in low yielding and high yielding environments, respectively. Cluster analysis, based on grouping locations, showed that P101 was the preferred variety in low yielding environments, and P98, in high yielding ones. It was suggested that the use of both stability and cluster analyses might give better results. Comparison of cluster and stability analyses showed that the stability analysis fails to recommend cultivars to different regions where yield potential showed significant differences. It seems, however, that cluster analysis could be a powerful tool to examine G x E interaction. If the number of environments was sufficient, a separate stability analysis could be run in each cluster.Öğe Identification of Candida species and investigating antifungal susceptibility in Turkey(Elsevier Sci Ltd, 2014) Aydin, E.; Karakas, A.; Savasci, U.; Akpak, Y. K.; Caymaz, S. O.; Aydin, S.; Metin, D. Y.; Ozgenc, O.; Avci, M.; Gul, H. C.; Coskun, O.; Coskuner, S. A.Öğe A Large-Scale Outbreak of Trichinellosis Caused by Trichinella britovi in Turkey(Wiley, 2009) Akkoc, N.; Kuruuzum, Z.; Akar, S.; Yuce, A.; Onen, F.; Yapar, N.; Ozgenc, O.; Turk, M.; Ozdemir, D.; Avci, M.; Guruz, Y.; Oral, A. M.; Pozio, E.An outbreak of trichinellosis occurred in Izmir, Turkey, between January and March 2004. The outbreak was caused by the consumption of raw meat balls made of beef deceptively mixed with pork infected with Trichinella britovi. A total of 1098 people who had consumed this food either in 14 restaurants or from the street vendors located in three different neighbourhoods, consulted six different healthcare centres with a wide range of clinical signs and symptoms. Of them, 418 (38.1%) patients fulfilled the criteria for the diagnosis of acute trichinellosis. The most commonly observed signs and symptoms were myalgia (89.2%), arthralgia (69.9%) and eyelid (67%) and facial oedema (65.8%). High levels of creatinine kinase (69.3%) and lactate dehydrogenase (93.8%) with leucocytosis (> 10 000/mm(3), 58.9%) and eosinophilia (> 1000/mm(3), 60.5%) were the most prominent laboratory findings. All, but 13 of these patients were treated with mebendazole or albendazole. Based on the physicians' assessments of disease severity, 78 (19%) patients were additionally given prednisolone in whom a significantly more rapid recovery of clinical signs and symptoms (e.g. fever, myalgia, facial and eyelid oedema) was observed, with a rapid improvement in leucocytosis, eosinophilia and muscle enzymes, compared with those, who had not received corticosteroids (P < 0.05). Beef illegally mixed with pork of unknown origin, by a wholesale butcher who had sold this product to restaurants and street vendors at a lower price than the prevailing market price of beef, was the cause of this large-scale outbreak in a country with a predominantly Muslim population.Öğe Structure, management, operation and mechanization possibilities of the irrigation systems in Turkey(Farm Machinery Industrial Research Corp, 2008) Asik, A.; Unal, H. B.; Avci, M.; Demir, V.Almost all of the irrigated agricultural land in Turkey is served by open-canal gravitational systems. Water in these systems is regulated by hand-operated gate control and measurement. Nearly all of these systems were constructed by the State Water Works (DSI). From 1993 onwards, transfer of operation and maintenance of these systems to water users' organizations, principally irrigation associations, was accelerated. At present this work is to the point of completion. This paper seeks to evaluate the structural, management, operational and mechanization status of these systems, both before and after the handover. And further to point out the problems that arise from structure and management that need to be overcome for the success of sustainable water management in the operation of these systems, and emphasizing suggested solutions to these problems: financial measures for renovation and modernization; legal measures such as reforms to facilitate the organization of the associations; and educational measures to train farmers and personnel in irrigation.
